1, no show boot
as memory reasons for this failure is usually because of memory caused by poor contact with the motherboard memory slots, as long as smear his finger back and forth with the eraser part of the problem can be solved (Do not use alcohol cleaning), there is damage or motherboard memory slot memory problems can also cause such a failure.
as memory causes no show boot failure, host speakers usually a long beep (for Award Bios speaking) 2, Windows systems running unstable, often have illegal error
for this failure is due to generally poor quality of the memory chip or software causes, should the memory to determine the reasons is only one way to replace.
3, Windows Registry Table often without cause damage that prompts the user to restore
requirements such as memory failures are generally caused by poor quality, it is difficult to repair, replace only one way.
4, Windows often automatically enter safe mode
Such failures are generally due to motherboard is not compatible with the memory or the memory caused by poor quality, common in some do not support the PC133 memory for PC133 memory on the motherboard, you can try to reduce the memory within the CMOS settings to see the read speed can be not solve the problem, should the impossible, it can only replace the memory of the.
5, random crashes
such failures are generally due to using several different memory chips, because the memory speed to produce a different time difference resulting crash, which can reduce the memory speed within the CMOS settings to be resolved, otherwise, only use the same model 内存. Another possibility is that memory is not compatible with the motherboard, such a phenomenon generally rare, there may be another memory poor contact with the board shall cause random computer crashes, such phenomena are more common Dao Shi.
6, after the memory increase system resources would reduce the
such phenomena are generally due to the memory board is not compatible with the cause, common in PC133 some do not support memory for PC133 memory on the motherboard, even if the system reinstall does not solve the problem.
7, Windows starts, the load when the high-end memory file himem.sys have prompted some of the addresses problem
this problem generally is due to memory corruption caused some chips, a solution can be found in the following memory maintenance of a law.
8, run some of the software often prompts
memory general this phenomenon due to lack of space caused by the remaining system disk, you can delete some useless files, leaving some space can be, generally remained in the 300M or so is appropriate.
9 from the hard disk installation guide to detect the disk space Windows Jin Xing, the system prompts the memory Such failures are generally less than
in the config.sys file because the user added the emm386.exe file, just out of its shielding problems can be solved.
fact from the hard disk to DOS mode boot to install windows in the Methods complex and slow one, have to install DOS files on the hard disk, and also configure the config.sys and autoexec.bat files, if files are configured incorrectly, will trigger a series of cases of unforeseen failure, for the very beginners not practical. Second, windows into a successful, due to start the system each time config.sys and autoexec.bat files are transferred to CD-ROM drive, make the system start-up time extension, should the config.sys and autoexec.bat masked after sometimes drive under the windows can not work properly.
10, install Windows to the system configuration, create an illegal error
such failures are generally due to damage caused by memory, the memory repair can be a method to solve, should the No, it can only replace the memory of the.
11, start Windows, the system automatically restarts
many such failures are generally due to memory or power quality problems caused, of course, the system re-start there CPU cooling may be bad, or other human error caused this, the only step by step with the exclusion rule.
memory alarm problem in the frequency of the phenomenon of computer failures at most, while the most easily solved —- open the chassis, the memory to pull out, then plug the look just fine. seriously, it needs to be cleaned of dust inside the chassis, or try another memory slot. compared to other computer hardware failure, memory alarm can be said to be the most simple hardware failure of the is no contact with a computer rookie, under the guidance of the phone can easily these problems.
we have to analyze, why Xianchu alarm memory, there exist memory alarm, how to solve such problems? memory alarm root causes:
1). memory corruption.
2). motherboard memory slot damage.
3). motherboard memory circuit power supply or related problems.
4). memory and memory slots bad contact.
1). memory slot deformation
such failure is not very common, usually found in a deformation motherboard, memory slots for damage, cracks and other phenomena, when we the memory into the memory slot from time to time there will be some poor contact conditions, when the host power-on self test when it can not boot, there will be a row of short \alarm. \memory process, we must pay attention to the direction of the memory, though memory and memory slots are foolproof design, but there are still many rookie insert the memory counter, resulting in memory and memory slots pillow melting of the situation of individual pin , then abandon the use of only the damaged memory slot. pillow melting of memory for the pin, we can double check, if it is only 77 and 85 pillow melting ground side, or maybe the other ground-side memory, even if Finger burned off, and this memory is grounded due to end in the anti-plug power supply with the ground when the short circuit, and led to ignition and burning memory of the golden finger pin memory slots, and memory chips are not any injury, so this memory as long as we plug it in the normal memory slot can be used normally.
sometimes we have to note whether there are other memory inserted foreign body, because if there are other foreign body inserted in the memory slot, insert the memory when the memory can not be inserted in the end, the memory can not be installed in place, of course, turn alarm situation occurs. When we plug the memory is still not solve the problem many times, it is best to check carefully whether the deformation of the memory slots, whether the pin deformation or damage, loss, slot whether a foreign body, etc., this helps us to troubleshoot.

Maintenance is the key board and exclude common me

Maintenance is the key board common failure classification and troubleshooting PC computer
motherboard is the most integrated accessory products, is most likely one of the faulty parts. A high level of integration to the maintenance hassle, maintainability less and less.
but often caused by the board computer failure is very easy to solve, as long as we grasp the good way, maintenance is not difficult for them, then I would 详细 introduction about the classification and motherboard failure exclusion method.
a motherboard fault classification
general, we can board fault is divided into four categories: The first category is based on the impact of computer failures can be divided into non-fatal and fatal failure. non-fatal fault has occurred in the system, Power On Self Test, is usually given an error message; fatal fault occurs in power system self-test period, the general freezing. is based on the extent of Type II can be divided into partial failure and overall failure. partial failure of a system to run one or several abnormal features, such as print control chip on the motherboard is damaged, causing only online print not normal, does not affect other functions; overall failure often affect the entire system’s normal run, so the loss of all functions, such as clock generator damage will paralyze the whole system.
III is the failure phenomenon can be divided into the stability of the fixed fault and fault instability. Stability of functional failure is due to component failure , circuit breaker, short circuit, the phenomenon of stability of its repeated failure, not failure often due to poor contact stability, components degrades the performance of the chip logic function is sometimes normal and not normal when the critical state caused. as as I / O slot deformation, resulting in display card and the socket connection is bad, so display error status was uncertain. Fourth, can be divided into different levels according to affect the independence of failures and related faults. independence of single-function fault Zhi Wan Cheng chip damage; related failure means a failure associated with other failures, the failure phenomenon of many non-functional, and its failure to control the various functions in real terms in the common part of the failure cause (such as soft, hard disk subsystem are not normal, and soft, hard disk controller on the control of its functions are more isolated, fault on the motherboard peripherals often control the DMA data transfer control circuit).
II motherboard failure caused the main
1, human Fault: Live pluggable I / O cards, and board and plug in installed when improper force on the interface chips damage.
2, bad environment: a common cause of static electricity on the motherboard chipset (especially CMOS chip) is breakdown. In addition, the board met damaged or mains voltage power generated peak instantaneous pulse, they tend to damage the system board near the chip power supply plug. If the board covered with dust, can also cause signal short circuits.
3, device quality problems: As the chips and other damage caused by bad quality devices.
3, motherboard troubleshooting common method of repair is often manifested in
motherboard fault system failed to start, no display screen is difficult to visually determine the fault phenomenon. Here are the maintenance methods have advantages and limitations, often in combination.
1, cleaning method: brush can be used to gently brush the dust on the motherboard, also, some card board, chip pin form often because of poor contact pin-oxidation. eraser to the surface oxide layer can be used to re-plug.
2, observe the law: revision of the board to be repeated view to see the plug, the outlet is skew, resistance, capacitance pin if bumped, surface is scorched, the chip surface is cracking, copper foil is blown on the motherboard. have to see if there is foreign matter between the components fall into the motherboard. encountered areas of doubt, the amount of what can make use of multimeter . touch the surface of some chips, if abnormal hot, can try for a chip.
3, resistance, voltage measurement: In order to prevent accidents, what should be measured before the power-board +5 V and ground Shang Dian Yuan ( GND) between the resistance. The most simple way is to measure the power chip resistor between pin and ground. not insert the plug, the resistance should normally be to 300O, the minimum should not be less than 100O. retest about reverse resistance, slightly different, but not too much difference. If the positive and negative or close to the conduction resistance is small, it shows a short circuit occurs, check the short reason. produce such phenomena because there are several :
First, the system board has been breakdown of the chip. generally more difficult to rule out the possibility that such a failure. such as TTL chips (LS series) +5 V together, can absorb +5 V pin on the solder, its suspension, one by one measurement, and to find fault the film. secant method, if adopted, will inevitably affect the life of the motherboard. Second, the board’s resistance and capacitance of damage. Third, there are board conductive debris.
When excluding short-circuit fault, the plug in all the I / O cards, measuring +5 V, +12 V and ground are shorted. In particular, the signal is +12 V and bumped around. When there is a good hand on the same type of motherboard, can also be measured resistance Difangface board of doubt, by contrast, can quickly Faxian chip failures.
Dang Shangshubuzhou O’clock were not effective, you can plug in additional electronic measuring Jiang Dian Yuan. Yiban measuring the power of +5 V and +12 V. When a voltage is found to deviate from the standard value too far, you can cut through the separation or some wire or unplug some of the chips and then measure voltage. When cut a certain wire or disconnect a piece of chip, If the voltage becomes normal, then this leads to the component lead or pull down the chip is the failures.
4, swap exchange: the host system to produce failure reasons, such as its failure or motherboard I / O Bus on a variety of card failure can cause the system to not run properly. with plug repair method is to determine the fault in the motherboard or I / O devices to fast-track approach. The way is off the board-by-piece pull out, pull out one of each plate observed on the boot machine running, once pulled out a piece of board to run after the normal, then the cause of the malfunction is the fault of the plug-in board or the appropriate I / O bus slots and the load circuit. if it pulled out all the plug-in board is still not start after the system normal, the fault is probably in the motherboard. Caiyongjiaohuan France essentially Jiu Shi Cha Jian Ban will be the same type, bus Fangshiyizhi, Gongneng the same plug-in board Huo Xiang Hu chip, the same model of mutual exchange of chips, according to the changes in the phenomenon 故障 Panduan Guzhangsuozai . This method is mainly used easily swap the maintenance environment, such as memory self-test error, the same interchangeable memory chips or memory to identify the problem.
5, software diagnostics: a randomized diagnostic procedures, special maintenance diagnostic card and in accordance with the technical parameters (such as Interface address), self-specific diagnostic procedures to assist hardware maintenance can reach maximum effectiveness. program testing The principle is to use software to send data, commands, line by reading the state and a chip (such as Register) to identify the fault position state. This approach is often used to check a variety of faults and has the address of the interface circuit various circuit parameters. However, this method applied based on the assumption that CPU and bus operating normally able to run the diagnostic software, can run installed in I / O bus slots on the diagnosis of cards. preparation of the diagnostic procedures are strict, comprehensive and focused, allowing some Guanjianbuwei law appeared in the Xin Hao, able to repeatedly on the occasional Guzhangjinxing Ceshi and can display Jiluchucuo situation.

Solving the seven examples of common faults Mother

admin — Fri, 03 Sep 2010 03:11:42 +0000

As the motherboard components and integrated circuits are numerous and complex, resulting in the causes of the relatively more than the memory than can be said to frequent parts failures. In general, their performance after the motherboard failure quite intuitive and good judge. as can not boot, the boot is not lit after the display points, and so on, basically related with the motherboard. we judge motherboard failure, usually by the gradual removal or replacement of motherboard is connected board (memory, graphics, etc.), first rule out these accessories problems that may occur after the target can be locked to the motherboard. other start to fail, no screen display Deng soft failures, motherboard also has a great relationship. the following, the writer instance for the information to you about some of the common , easy fault finding and troubleshooting methods.
fault one: a normal use of the computer broke down, specific performance is in use, often inexplicably reboot, and sometimes even crash . re-install the operating system, the fault persists.
fault analysis: such failure may be due to the driver board caused by the loss. In many cases, such as computer viruses, errors such as misuse after shutdown , will board the driver lost out. Since there are many motherboard after installing the Windows system does not need to install drivers, resulting in a lot of friends, a reduction of this step. Although most cases do not install drivers for the motherboard systems able to work, but there is no guarantee of stability. Therefore, it is recommended you right after the installation of your system motherboard to install the driver program.
troubleshooting method: we can drive the control panel to battery pack is installed correctly. is in turn open the \\; 4 In 1 \Compatible often fail to start recently, occasionally to frequent crashes into the system is seriously affected the work of friends and game entertainment.
Failure Analysis and Troubleshooting: According to a friend describing the failure phenomenon, I initially judged as caused by viruses or hard disk itself problems. in accordance with the first after the hard-soft, simplest to complex maintenance principles, and show the latest anti-virus software on the hard disk to prepare for killing, but with the boot disk into DOS mode, but not able to find the drive, it seems antivirus is unable to 了.
restart the computer and the mobo BIOS, found no irregularities hard Shen Shu, but it can not be identified automatically detect the hard disk, have shown that such software is not a problem, just check the hardware has. open the case, the hard drive power cable and data cable unplug and re-plugged in, boot, or does not recognize the hard disk. Could it be a problem hard drive? to completely rule out the hard drive failure, friends, love machine will remove the hard drive on the machine I received (set jumper to slave), open access to the hard disk checking software to scan and check this piece of hard disk and found no problems. data on the hard disk copy and paste operations can also be normal, indicating the hard disk itself does not have any problem.
Is the data cable or power line problems? author of a new data line will be re-received the computer, and replace a four-pin power jack ladder, reboot, trouble still. will not be power power insufficient? author friend machine the power to conduct a comprehensive inspection, saw a friend using the Great Wall 300W power supply should be no problem. This is why? Is not motherboard problems.
carefully observe the motherboard , hard drive connected to the IDE1 interface, drives connected to the IDE2 interface, why the hard drive to use is a problem. try to drive removed, received the IDE2 interface hard disk, hard even to normal use. scary, how good IDE2 The IDE1 fail, but they are controlled by the same master chip, ah! desperation, had to remove the motherboard to observe, then found the back covered with dust in several places, including one right in the solder joint interface IDE1 Department, the accumulation of dust covered almost joints.
dust will lead to the IDE1 these interface issues, no matter, to say first clean up the dust. The clean-up fixed the board, well the parts installed, restart computer smoothly into the system, everything back to normal. It was these humble dust into the real perpetrators of this failure.
fault Summary: dust is invisible killer computer, prevent the heat accumulation of dust, easy to damage the element devices, in wet weather also caused a short circuit phenomenon. dust on the mechanical parts of the computer have a great impact. Therefore, on a regular basis to the love machine do health is particularly important.
Fault 3: poor heat dissipation, resulting in damage motherboard capacitor failures exclude
fault performance: I assembled a year ago, a compatible computer, the latest in a continuing playing 78 hours of the game, suddenly a black screen, no reaction will again press the power button and the machine chassis still nothing happened.
Failure Analysis and Maintenance: Now that the computer did not reflect, most likely a hardware failure problem. as this situation should first rule out a general power failure. to open the case, it was discovered press the power switch power supply fan. CPU fan is turning, indicating power supply is no problem. It seems the power is no problem, according to the author’s experience, in which case CPU normally does not burn, but the most memory malfunction. but the memory problems Generally, the police, and the chassis of the speaker without any reflection, it seems the problem of memory is not large. relatively easy to rule out the possibility of memory failure, so I love the plane of a 512M DDR400 memory removed, replaced a normal use 256M memory, so the problem remains the same, does not appear in any of the problems.
poor contact will result in certain parts of it? So I put the chassis refresh all plug-ins are a bit, press power switch can still nothing happened. This problem can be under more complex, and appears to be motherboard problem. borrowed a board to all parts of the original machine plugged in to a test result, the machine smoothly and enter the system through the self-test , this shows there really motherboard failure.
remove the broken board, carefully observe the various components on the motherboard, in particular, check the motherboard’s capacitors and transistors, and try to touch his hand then the temperature of components, focusing on part of the CPU power supply were examined. checked and found no problem days. motherboard turned on when I will come back and check the motherboard, and found near the three-pin appears to have a number of yellow? to turn a motherboard of view, this corresponds to the three pins is a small heat sink containing three pins component. according to component model is found to be a step-down management, test out a multimeter and found the two pins short-circuit No wonder the inspection found no problems when the board in front of it, the original of this step-down pipe with a small radiator, was ignored in the inspection.
determine possession of the step-down problem, immediately went to electronics market re-bought a new, carefully iron welding power up, plug in other components, turn on the power, everything back to normal, and sure enough that is the the last. The buck control how the emergence of short-circuit it somehow? So I In the case of driving the machine feel a bit step-down control on the heat sink, ah! pressed in! No wonder the circuit board will be roasted yellow, and such a high temperature of this new management has replaced the buck was barely how long.
author is selected at the time installed a small box, had heat is not good, this is not closed under the chassis heat sink side of the case are this hot, close the case even after the cooling conditions difference. In order to completely rule out the fault, I decided to replace a large radiator. Turn off the power back to the step-down tubes with a large heat sink. once again turn the temperature is kept within an acceptable range, for insurance, during which I stick in the heat sink, a small fan, which is basically under the heat sink does it feel Wen Wen’s.
fault Summary: As the number of motherboard manufacturers, so the use of materials and workmanship and uneven, and many no-name second-tier motherboard But not only work hard, but not very full at the selected materials, combined with good thermal environment, very easily lead to the motherboard capacitor or other component devices appear burned. Consequently, when you in choosing motherboard makers have to choose first-line products, In addition, even if further work materials even the best foot board, if long-term work in high temperatures, long time can also cause burning of the phenomenon of capacitive elements, so we must pay attention, do a good job cooling the work, to prevent accidents .
larger motherboard is the place to gather more dust. dust, is likely to lead to the phenomenon of poor contact socket and the board, then we can toward the slot and play on air, remove dust. If it is the oxidation caused by poor contact pin socket, and can be folded with the hardness of white (smooth surface, it-out), insert slot wipe back and forth. In addition, CPU slot used to detect CPU temperature, or board to monitor the temperature of the thermal resistance of the chassis attach the dust, then, is likely to result in identification errors motherboard temperature, causing a motherboard failure protection issues also need attention during cleaning.
demolition equipment chassis, do not fall into care, such as small screws like conductive material may be stuck in the motherboard causing a short circuit between components, will rise to a \installed between it and a small board for support of small copper pillar; whether the motherboard installed improperly or motherboard and chassis, chassis deformation Ershi direct contact, so that short-circuit protection with automatic power cut off power supply.
Fault 4: by the board failure caused the problem can not be properly shutdown.
fault performance: a computer two years ago to buy the brand, AT motherboard architecture appeared normal shutdown Windows 98 operating system can not fault. When the \, Windows 98 icon and \operating system troubleshooting, but without success. repartition the hard disk, then install Windows 98 operating system, the installation process, the second restart, the computer can not properly shut down the.
fault analysis excluded: I can not determine the normal shutdown caused by the motherboard failure. so inform the computer company, ask them to send someone to replace the motherboard. by the company’s full-time maintenance personnel inspection, confirmed the author’s judgments. replace the motherboard, the failure Exclusion . The other computer has similar problems. machine configuration ATX motherboard architecture, out of the box test machine, the Windows 98 operating system appeared not to shut down the fault, when the \\The results prove it right, replace the motherboard, the fault disappears.
fault Summary: Board of such failure not only in the AT architecture of the motherboard appears, may also appear on ATX motherboard architecture. if such failure , in general, that the board had a problem in their case can not be solved, only replacement of the motherboard.
Fault 4: Upgrade the system stability after the computer can not run
failure phenomena: one using the Windows 98 operating system computer, the recent upgrade to the Windows 2000, can not be stability, often crash or restart of the phenomenon.
Guzhangfenxi: this case Yi Ban is due to the system caused by the strong Jianrongxingbu. As motherboard BIOS too early old, poor recognition of the new operating system, with the result of such failure. In addition, some hardware devices during the upgrade will happen. As the board design or upgrade parts BUG occurs when old and the new compatibility issues, the exclusion problems BIOS settings can download the latest motherboard BIOS refresh.
Skills 1: Clear the CMOS settings, you can solve some \.
Skills 2: When installing the operating system the hardware can not be identified when CMOS setting \
failure five: Capacitance aging cause the machine to reflect inactive
failure phenomenon: there is a Soltek motherboard, using the point of not more than two years after the sudden light, and showed when the switch is closed, power supply fan, CPU fan in turn, but the optical drive, hard disk does not reflect, and wait a few minutes before power-boot machine, starts as usual. to re-start no problem, but a power off and then open as above would like to wait a few minutes. start that is the power problem, replace the still after the failure. replace the motherboard, all the normal, that is, a problem with motherboard. board is the author of a friend, so I check to see if he can repair.
Troubleshooting: from failure analysis of phenomena, motherboards can work with electricity after, indicating motherboard chip is good, the problem may in part on the motherboard’s power supply. but the power supply fan and CPU fan can be in normal operation, indicating the total normal supply of electricity. Power-Run After a few minutes power failure, by smell no smell, hands touching the power part of the electronic components (mainly capacitors, inductors, power regulator IC), found in several CPU next to the capacitor, inductor temperature is extremely high.
you know, electrolytic capacitor to work under long-term high temperature will cause deterioration of electrolyte, which will change capacity. so I initially judged that the two capacitors in question. to find a fault, so I immediately rushed to the market to buy electronic components procurement. and will be carefully welding the damaged capacitor, the capacitance of the new re-welding bought up.
weld capacitor, I have not installed CPU, the first power-up test, test a few minutes, the temperature is normal. then add CPU, plus electricity, screen immediately lit up. so I tried a few times more, and pay attention to the capacitance of the temperature. capacitor temperature is normal, but from the power-up to the light seems slower than normal seconds, it is estimated there are other capacitor problem, so double-check, find a 4500mF capacitor also some deterioration. In order to completely rule out the problem, then went to the market to buy back a capacitor with the model, to replace up. boot test, so a couple of hours continuous pagers are not found in problem, even if this is repaired! a motherboard a few hundred dollars, and two capacitors only two yuan, so maintenance is very valuable.
fault Summary: In general there is a problem if the board, mostly because it is part of the motherboard capacitor aging or damaged, so we can start checking the maintenance capacitor start, careful investigation and, ultimately to find source of the problem. In addition, the need to remind everyone that, since we rule out the capacitance of aging is the most direct way Check the temperature of hand capacitance, while the electronic components afraid of static electricity, so touch the capacitors on the motherboard components, we must first let go of him completely static, the most direct way is to wash or touch the metal , conditions can take anti-static wrist loop.
Fault 6: abnormal temperature rise motherboard motherboard \chip can monitor CPU temperature, so the purchase of the motherboard, the other purchased a 2Pin temperature monitoring line inserted in the slot next to the JTP CPU pins. Later, in a process of playing the game, the machine suddenly blue screen, After rebooting, wait until the CD-ROM drive, hard drive self test finished monitors do not even bright. As previously reported blue screen error, at first thought it was the memory error, was still valid after replacing the memory.
it in the end how the case? So the author in accordance with the minimum hardware elimination, will drive, motherboard, hard drive and other 11 removed for testing after the change, the result was of no avail. is not the CPU burned out? So I began to suspect that CPU failure, borrowed a friend of a CPU for a try, failure remains. Could it be a faulty motherboard, of resignation, the focus began to check the motherboard I suddenly discovered that the temperature control on the motherboard connected line off, swap the motherboard temperature monitoring hh is it the fault line caused it? reconnect Temperature control lines, then all the normal boot actually has.
failure analysis: As the CPU heat is very large, many motherboards offer a strict temperature control and protection equipment. General CPU temperature is too high, or the motherboard temperature control system fails, the motherboard will automatically enter the protected status. refuse to power-start, or alarm. the above example is the motherboard temperature monitoring line off as a result automatically protect the state board refused to increase power. So when your board can not normal start or alarm, first check the temperature monitoring device under the board are normal. Also in many cases because there is no cooling fan in close contact with the CPU, resulting in CPU temperature is too high, also have frequent crashes of the phenomenon.
Fault 7: board anti-virus does not shut down, resulting in system failure can not be installed
phenomenon: a old Celeron machine configuration, the installation of Windows 98 and found that the screen on stage in the installation of Chu Shi sudden emergence of a black rectangular area, such as what advice , then stop installed. Adjust the display brightness and contrast switches are also invalid, feelings, and virus. killing the virus with anti-virus software and did not find any viruses.
Troubleshooting: Under normal circumstances such failure is due to some parts caused by excessive heat, open the case carefully examined, and no excessive heat phenomenon. It seems the computer hardware is no problem. will not the machine poisoned? In DOS, the latest anti-virus software on the computer After a comprehensive anti-virus to install the system, fault still.
motherboard will not be anti-virus function doing strange invasion, and then view the board’s instructions and found that this board does have this feature. into the CMOS setup program , the \success.
Failure Analysis: This phenomenon occurs more easily purchased in the new motherboard, because of their anti-virus settings in the BIOS default setting for most of Enabled, it appears the problem can not install the system. this problem, strictly speaking, board should not be considered failure. but not very often pay attention to many users, leading to frequent.

Common failures caused by bad power

admin — Fri, 03 Sep 2010 03:11:15 +0000

Power is the power base of the host computer is a mainframe computer accessories power source, power supply output current directly influences the performance of mainframe computer parts and service life. If the CPU for the computer than the \entire computer host \a carefully selected computer \All parts of this for the host to provide an important source of power components: power supply. According to statistics, over 70% of computer failures are caused due to power quality. users due to the use of poor quality power supply and there’s all sorts of strange phenomena of countless failures. The following Some are listed because of poor power supply failure caused by the common phenomenon:
1, into the system, the display appears on the screen ripples interference. long-term vision will cause 损害 Zhe Yang.
2, the hard disk bad sectors appear likely, although has bad sectors can be repaired with software, but not for power is easy to damage the hard disk, causing data loss.
3, low-quality power supply filter circuit Discovery works by material, large output voltage ripple, resulting in sound noisy. 4, drive read the disk performance deterioration, occur frequently read the disk crashes, drives to shorten life.
5, overclocking instability
6, install multiple hard disk system does not start, or difficulty in starting. 7, the system frequent random restarts.
8, the computer starts, cause interference to other electrical appliances, such as drop-definition TV, there stripes or textured interference.

Case studies address common failures card

admin — Fri, 03 Sep 2010 03:10:23 +0000

In the PC computer, graphics, and the probability of failure is not great, but graphics cards caused by the fault, different from the failure so good deal, because at this time computers are very likely to be black or Huaping state, can not see the screen prompts , the user is also difficult to rule out even the master fault. Therefore, if the display card itself there Liao Wen Ti, Zhi Neng sent Zhuanye the Weixiuzhongxin Jinxing detection and maintenance. But in many cases the computer screen can not display fault Bingbu Shi Zhijie You show Damage caused by hardware, so we can some small way, their own hands rule. The following summarizes some of the graphics card and the associated fault for reference.
1, graphics and motherboard socket connection is bad fault analysis excluded
If the screen after boot no display, we can first check whether the graphics card and motherboard socket loose or take bad angle. In many cases, as deformation caused by poor contact board is seen by the naked eye, such as a high card an end, it is easy to be excluded. but some cards are hidden poor contact, the surface installed well, but in fact poor contact, resulting in many inexplicable failures. The following terms through Two Cases poor contact with the board about graphics Trouble.
Case 1: Recently, I suddenly can not start a friend’s computer. start phenomenon: the computer self-test process in a \This is a graphics card failure (motherboard is the Award BIOS). to open the case, the card re-compaction. start the computer, trouble still. Could it be graphics card bad? remove the video card plugged into another computer, the computer starts normally. yet others a card inserted into the machine properly, the phenomenon to reproduce.
motherboard the problem? I carefully observed with a magnifying glass motherboard AGP slot, found no abnormality. To check whether the connection is bad, I will swap cards repeated many times were different, and enable the graphics on both sides of the whole and to different depths into the slot. When the trial to the graphics interface to end up with slight upward tweak the time, with a loud sharp short-ming, the computer finally started. then test the graphics card in real again, computers can not start.
the cause, so I installed graphics card when the washer baffle under the mat in about 1.5 mm thick cardboard, tighten the screw, the computer normally. After summarized for the following reasons: because the chassis is a vertical Fangzhi friend’s, Er friends in order to save space, Yi Zhi buy the cabinet level, and display Fangzaishangmian. Youyu computer desk Bingbushifen formation, Shi computer display into a Qingxiejiaoduo, Over time, board deformation, resulting in not very good graphics card and slot access. It seems the computer’s display is not insignificant, if placed properly, so motherboard deformed, will produce a variety of failures.
Case 2 : a Sempron machines, is the month of 2006, 7 installed. some time after the boot is not normal, often at the first turn black when no response, cut off the power before turning on power is successful, like the system to \\and carefully tested, this configuration also purchased other machines did not show such a failure, then proceed from the principle of simple steps, first check the connections, plug it again after the turn, invalidity; in the power settings from the CMOS been adjusted, set the factory default values, null and void; upon inquiry was informed that this machine a few days ago to open the case had been cleared of dust. Thus, the estimate is a component loosening led to poor contact or short circuit.
solution: boot When carefully observed, the panel found that bright light is not immediately, but after 5 seconds after the light, power light, hard light and optical panel lights are normal, just like the system no signal sent to the display, but no alarm system Acoustic mm as the second boot to normal use, so do not rule out the black plug is the reason why the memory. general system memory and graphics card boot black screen is caused by two factors, the possibility of damage to a small board, so I judge may be failure caused by poor contact cards. So, after re-plug, in turn discharge CMOS jumper. After the reboot, a successful, post back to CMOS settings, tested normal, thus solve the problem.
2, power supply or set of
motherboard now advanced power management features offered by many, there is energy, sleep, ON NOW, etc., but some graphics cards and motherboards have some power function of the conflict, will lead into the Windows O’clock Huaping phenomenon. Case: The machine began to doubt in the commissioning process is a power failure, change the CMOS settings in the power supply, in particular the VIDEO related settings, boot into Windows98 进入 Windows after a 256-color, also prompted to install the new drivers. This machine has normal use for six months, and apparently the basic cause of the failure to set wrong, and not by Windows prompt \CMOS power options into the Windows problems immediately after, so no effort to know the impact of power supply options. But if other circumstances arise, may be more difficult to think of this area. recommended not display properly when take note of CMOS power implications, if changes to the settings, it adjusted to factory default value; If you are just installed on the problems, can the factory default value of the energy-saving, ON NOW prohibit any fancy features try. Moreover, because the power consumption of AMD’s CPU large number of poor quality or power supply is not enough, add the purchase of a new larger hard drive or other power equipment, may also cause the power supply is not enough graphics card, you can use exclusion and substitution test.
3, after the BIOS update of
almost every month, there will be graphics card manufacturers release new BIOS on the Internet for DIY their own graphics refresh to get new features and revised BIOS the BUG. but there are many people in refreshed after the crash when playing some games, or automatically jump back to the desktop, and more brand-name manufacturers BIOS brush with bad cases of their own cards. If the refresh task after most of the normal Windows, just a driver error, such as PHOTOSHOP, you can hardly think of is to update the BIOS of the impact, so troubleshooting may be detours.
suggestions: your graphics card working properly, it is best not to abuse \each version of the graphics card BIOS computer motherboards, power supplies have a certain fit (compatible) features, if the current components are friendly, then he do not make a good change. refresh after the so-called new features, in fact most of vainglory . motherboard’s BIOS is the same, unless it is out of consideration to support the new CPU, nothing random brush a bit risky, not worth it. In addition, the graphics do not tighten the screws too tight too dead, medium can be, because the graphics in open box The baffle also point distance, if forced to tighten the screws too tight will pull slightly away from one end graphics card slot, may lead to poor contact. screw it, and against the will of the.
Tips:
General graphics and memory fault diagnosis of the difference between video card and memory problems, the computer boots are black, how different? the main points to note are:
1, note that computer or not trumpet the alarm sound alarm if there is sound, graphics of the problem may be bigger, and we can from the length and frequency of alarm sound to determine the specific failure (motherboard manual will appear Fudai specific method to judge, please got their own reference).
2 If the black screen without warning sound, mostly memory simply not plugged or broken. no memory computer simply can not be switched, of course, will not alarm.
3, pay attention to the display panel LED status, if no alarm has checked the memory, and may be poor contact card problem, often accompanied by the hard disk light Always; also can see the status display lights, a black screen with the monitor if the state regulation of light kept flashing at the same time, may be card to the monitor cable to connect the plug loose, or graphics inserted in the slot did not tight.

Common memory failure analysis

admin — Fri, 03 Sep 2010 03:09:51 +0000

1, no show boot
As the memory reasons for this failure is usually because of memory caused by poor contact with the motherboard memory slots, as long as smear his finger back and forth with the eraser part of the problem can be solved (do not clean with alcohol), there is the memory damage or motherboard memory problems can also cause such failures.
As the memory causes no show boot failure, host speakers usually a long beep (for Award Bios case)
Second, windows system operating instability, often produce illegal error
This failure is generally poor quality of memory chips or software causes, should the reasons for determining that memory is only one way to replace.
3, windows registry often without cause damage, prompt requires the user to restore
Such failures are generally caused because the memory of poor quality, it is difficult to repair, replace only one way.
4, windows often automatically enter safe mode
Such failures are generally due to motherboard is not compatible with the memory or the memory caused by poor quality, common in some do not support the PC133 memory for PC133 memory on the motherboard, you can try to reduce the memory within the CMOS settings to see the read speed can be not solve the problem, should the impossible, it can only replace the memory of the.
5, random crashes
Such failures are generally due to using several different memory chips, because the memory at different speeds to produce a time lag leading to crashes, which can reduce the memory speed within the CMOS settings to be resolved, otherwise, only use the same type of memory . Another possibility is that memory is not compatible with the motherboard, generally rare for such phenomena, while it could also be caused by poor contact with the motherboard memory computer random crashes, these phenomena are more common Dao Shi.
6, the memory increase after the system resources would reduce the
Such phenomena are generally due to the memory board is not compatible with the cause, common in some non-PC133 memory support for PC133 memory on the motherboard, even if the system can not solve the problem reloading
A compatible computer, configured for ASUS P3V133, Celeron 300A OC 450MHz, 64M HY PC100 memory, MGA G200 graphics card. Upgrade to PC133 128M after the failure, fault performance for the first time boot the system without any response, must be reset after a reboot or system to light, then the system working properly, shut down after a period of time, the next reboot failure remains.
Originally suspected to be poor contact card, or memory, after the failure to re-install still; they suspect that the memory card or cheat oxidation lead to poor contact, after the fault is still clean finger. So he suspected short circuit caused the motherboard and chassis failure, the motherboard from the chassis inside out, fault still exists, it seems chassis and motherboard, and there is no short circuit, and the exclusion replacement card and the same memory, breakdown is still not resolved. It seems not at fault because the video card or memory.
Day by chance, because the frequency at overclocking processor cause the machine can not be set too high light, after clearing the BIOS, but found fault disappears, it seems closely related to BIOS settings and the fault!
So Anzhao old habit of trying to set the optimal BIOS, found that the memory parameter, the system would have appeared before the failure! Seem to find the cause of the malfunction. Then set to CL = 3, Troubleshooting. The author of this memory is the memory When the purchase price reduction, although support for PC133, but the CL parameter is only set to 3, set to 2, although very stable in use, but it is for this reason that leads to boot failure.
Although relatively rare in the case of failure, but from this failure, we can see that the quality of memory for system stability are closely connected, in particular the current memory market, the quality varies greatly, many users neglect this important parameter CL, hope The case of failure so that everyone can buy time in the parameters of the memory attention
Start the system or run the application, the system reported: \and memory reduction, memory parity errors and different.
System reported \is set in the CMOS system startup memory above 1M is not self-test, run the application in the system reported \is a software fault; Third Power On Self Test passed into DOS or Windows platform to run applications in the Times \The memory caused by a software fault error, according to the following steps to check and deal with:
1. If it is in the DOS environment, run the application Times \or re-write the system configuration file to resolve the issue on the application can be resolved through the appropriate changes.
2. If you are running under Windows environment application procedures Times \reinstall the system and applications to solve.
3. If the question is in the running for a particular application, it appears, may be caused by the software.
4. Using KILL or KV300 + detection system is infected, there are anti-virus.
Memory errors caused by hardware failures are more common, CMOS settings wrong, memory connection is bad, wrong combination of memory installed, memory hardware damage, memory controller, a memory error with porosity, error, general inspection and treatment according to the following steps: 
1. As the Power On Self Test is displayed \or memory read and write memory wait time is less than the actual value, should increase the memory read and write cycles, or increase the memory to read and write latency.
2. If the fault persists, check the memory slot with the contact between the memory sockets are good, and make the appropriate treatment.
3. If the fault has not ruled out, check the combination of memory installed is correct. General motherboard memory sockets are divided into several physical installation (Bank), each body has 2-4 sockets to install memory, the memory can be installed 2-4 section. As a 72-line memory can provide 32-bit effective data (30 lines memory has been eliminated, will not be discussed here), for Pentium class CPU, the data line 64, to one able to access 64-bit data , it is necessary to install two 72-line memory, so 586 computer motherboard, generally must be installed even line memory 72, that one should be installed 2 or 4 of Article 72 lines SIMM memory. If the memory on the motherboard Article socket is 168 lines, 168 lines of memory as a 64-bit can provide valid data, it can only work to install one. install memory should note the following: For most PC machine is not Bank will be in the same capacity of mixed interpolation of different articles with SIMM. a lot of different PC machines can be installed capacity of the SIMM article, but packed in the same group in all SIMM Bank article must have the same capacity.. For many PC- For instance, if the mixing of different speed SIMM inserted with the article, even if they are the same capacity, may cause problems. For example, the computer has been running at 60ns (nanoseconds) and 16MB of memory, if the motherboard’s free speed of the memory slot and then insert the SIMM 70ns article, the system will refuse to boot or is likely to start soon after the collapse. for some computer terms, if the low speed up to the first group of articles SIMM may solve the mixed problem of the speed, the computer will be the minimum speed of access.. For most of the PC, it must be a set of all the slots are poking, or a total blank (of course not work the first group), slot in a group can not just plug a part of memory.. PC machine accepts a maximum memory size (the maximum can be found from the PC machine instructions. if there is no manual, the only way is to find the maximum value from the practice a). SDRAM is the next generation of dynamic memory, also known as synchronous dynamic memory or synchronous DRAM. Although there are many motherboard supports SDRAM and EDO memory, mixed-install, but best not to mix. The reason is only 3.3V, SDRAM to work, and EDO memory will work most of the 5V voltage. While on the DIMM and SIMM board power supply, respectively, but their data lines always together, if SIMM (72 lines memory) and DIMM (168 Line SDRAM) mixed, although the system can start to work, but used for some time, may cause SDRAM data input is damaged. Of course, if your SDRAM is suitable for wide-voltage (3V ~ 5V) work product, on This will not be damaged.
4. If the fault has not yet resolved, check with the substitution memory is corrupted, and to make appropriate treatment.
5. If the above measures will not work, then suspect a problem with the motherboard or controller chip can be sent to professional maintenance
Computer memory failure is the most common type of fault, and most of them were different in not very good examination ruled out. Encountered some time ago due to computer failures of memory, and now the process of writing out the solution for reference.

Failure of a
Fault performance: a computer configured for Celeron 1.7GHz, 845D motherboard, two 128M DDR memory, but the boot display memory display 128M, occasionally display 256M.
Failure Analysis: open the case, it was discovered two different memory brand, design work are quite different, a question just of Main was originally a memory upgrade to increase. So first memory plugged into a separate machine on the test are shown for the 128M , no problem, but with the plug still show 128M, swap the memory slots are useless. It is clear that the memory compatibility issues cropped up and let him take the old memory to the market increases and the first post in exchange for a similar upgrade memory of memory, troubleshooting.
Maintenance experience: memory compatibility issues, though not many, but the damage is not smaller as they often have a lot of strange performance, we Haishijinliang Bimianbutong Xing Hao’s memory mix, so to avoid possible compatibility issues Neng’s 发生.
Fault 2
Fault performance: a computer configured for KT133 motherboards, Geforce4 MX440 graphics card, 128M memory, install Windows XP frequently crashes, has failed to properly install.
Failure Analysis: Upon request, the machine just to the main computer before the dust, after a system crash occurs, then the system was not installed. After a careful look at the hardware, and found that memory is not very clear there is a hard scratch hurt some of the PCB on the circuit, it seems a problem here. After switching to the other memory, fault disappears, it seems the original memory has been completely damaged.
Maintenance tips: When loading the machine, or dust, we must be careful not to damage the hardware, like accidentally damaged parts of things, be careful with this is completely avoidable.
Fault 3
Fault performance: computer is configured to 815EP motherboard, 128MB memory, the original use of normal, then get a 64MB memory, plug together, the total amount of memory is recognized only 64MB.
Analysis to solve: first memory of a plug into a separate board, confirmed to be good, you can rule out the memory of the quality issues, compatibility issues appear again. But Zheci memory with Huan the method is not practical, after all, white to The 64M memory a little small, for 128M memory also requires a lot of expenses. suddenly remembered motherboard BIOS upgrade may be memory support has increased, so the way the BIOS was upgraded to buy the first time since the fault was finally ruled out.
Maintenance experience: a lot of compatibility problems when the BIOS can be resolved by upgrading the motherboard, so often to see if there for their own BIOS, drivers download is not forgotten.
Fault 4
Fault performance: a computer configured to Celeron 667MHz, BX chipset motherboard, modern 128M SDRAM, one day suddenly turn black, buzzer alarm.
Failure Analysis: issued by the board can determine the alarm sound, most likely a problem with memory or the memory slot. Unplug another first memory slot, fault still appears normal memory slots; then change it for another insert a memory , the fault disappears. appears to be memory problems, but a bad memory for no reason is unlikely, so carefully look at the memory and found a thick layer of dirt cheat section, it seems the problem is poor contact. then get rubber part in the finger wipe several times, and re-inserted into the slot and found everything to normal.
Maintenance tips: Memory finger and slot contacts are good, very important for the stability of the work. If there is a similar connection is bad, we can just use rubber cleaning, a very simple computer dust or need to emphasize. 
Fault 5
Performance: Friends originally wanted to expand the memory capacity but smaller result.
Failure Analysis: Friends do not know where procured four different types of memory capacity and to all studded with four memory slots. Look at the manual, the total capacity of four memory board does not exceed the maximum amount of memory supported BANK motherboard seems to support the issue, really tested on three memory display are normal, once with the 4 memory, the total capacity but will appear as a memory capacity for memory, for the time being does not work, or remove a memory now it.
Maintenance tips: BANK supported by the number of motherboard you should pay more attention, not to say that board has four memory slots can support 4 must also depend on the number of memory BANK number with the motherboard support. And, in addition to support dual-channel and memory with two things, or suggest that you use a single large-capacity memory
Fault 1: to add a PC133 computer memory after the (original memory to PC100 memory), frequent crashes and hot running Kai.
Analysis and Resolution: This usually is due to the added memory and memory between the original, brand, speed, capacity is different or some different solutions can be used \Features seen in DRAM Timing By SPD is set to Enable, be amended to Disable. and then the DRAM Clock to 100MHz. Restart your computer troubleshooting. Should the still does not work, try replacing the memory slots, usually to faster memory inserted in a slot. If these methods fail, it is recommended in pure DOS, the BIOS on the motherboard update, the general problem can be resolved.
Fault 2: boot the system self-test to test three times to pass. Phenomenon: for inspection immediately start from scratch each test several times before it is passed.
Analysis and solution: the above problems encountered, usually because the memory self-test in the number of CMOS settings wrong. Just go to CMOS in the \Inspection will only be a memory test again.
Fault 3: with KT133 motherboard of a computer, using ordinary HY PC133 128 memory, frequent crashes in Windows, there’s illegal operations.
Analysis and solution: because the BIOS to optimize the user is working at optimal memory settings, it can be hard, but the quality of memory in this environment is often unstable. Enter the CMOS, will be in the Advance Chipest Features from the SDRAM Cycle Length 2 to 3, Bank InterLeave by the 4Bank to Disable. problem solving!
Fault 4: machine can not enter Win98, phenomena into the system automatically shuts down immediately after. With the safe mode boot, after reading Himem.sys prompt \Analysis and solution: According to the prompts, the problem should be with the motherboard or memory. Because the surface of the boot prompt Himem.sys files are memory errors, it is generally the first to find out from the memory on the issue. At this point you can try the following: (1) , will set the parameters in the BIOS conservative approach, the simplest way is to use the default BIOS parameters. (2), you can try clear the CMOS memory using the discharge means in the information. If these methods are not, propose to send repair motherboard point or direct replacement.
Fault 5: HY 128MB RAM, running Win98 normal, but after the upgrade to install Win2000, frequent interruptions, the state returned to DOS, and sometimes to complete the installation, but to run unstable.
Analysis and solution: CD no problem, will be replaced by King Max128 memory, was very smooth, very stable. Win NT / Win 2000 on the hardware requirements higher, installed on the hardware detection strict want Win2000/NT, preferably high-quality, large-capacity memory.
Fault 6: After booting the machine can not light up, and accompanied by a long 3 short alarm sound
Analysis and solution: According to a long three short sound the alarm could not judge a memory checksum error. Can be shut off to open the case to see whether there is loosening memory. In addition, if the memory on the finger with aging, can be used slightly damp clean towel gently wipe. then the plug will be the last of the original slot. problems generally can be resolved. Of course, to take note of these steps should ensure that all sockets are closed only after the power, otherwise easily lead to short circuit parts burned
Fault 1: As the use of poor quality can not be properly installed system memory result.
Friends of a machine need to reinstall the old system, I went to help. Configuration is: MSI 6340 motherboard, Duron 650, PC-133 Yuan Han 128M memory, no-name TNT2 graphics card, WD20G hard drive. Using ghost cloning software, a little over 7 minutes is complete. a friend that some of the software version is too old, no use of some software, requires redo an image file. Format C after-hours, with the installation CD-ROM reinstall Windows. nearing completion, the system can not suddenly prompted to copy files Installation failed. replacement installation disc, still stuck in the same place.
In desperation, use ghost to clone a system, then all kinds of testing software testing. The first to use 3Dmark2000 test, test, everything normal. Then Goldmemory (GM) testing of memory, in about 80% of the Department, the software error, suggesting that withdrawal . got a modern re-reload system 64M memory, troubleshooting. After careful observation, found that the root of memory with a memory far Han particle board and PCB solder joint has a very slight fracture, such as the casual observer, could not identify. Friends To save time, have been using ghost cloning software installation system, long hidden but have not made trouble. until discovered warranty has expired, except nothing with foreign hands are tied. hindsight that this failure is due to the use of quality but related memory, a long-term memory is poor contact particles, good times and bad result of the state. And because ghost cloning software is a hard drive can be forced to write data to a software fault undetected. It is my suggestion My friends in the purchase, remember to test the software in several more tests, so that the last regret Moji.
Fault 2: The use of lead has been damaged memory can not install the system.
I an old classmate, purchase a few years, has been properly used. Has suddenly called to say a system crash, need to reinstall the system. Configuration is: Asus P2L97, PII233 over 262, two modern 32M memory, HASEE Riva128ZX graphics, charm enterprise choke red pepper sound card, Quantum 4.3G hard drive. I arrived, the first CPU drop back to the initial frequency, and then format the hard disk, and finally install the system.
Installation, the system prompted to address errors, the installation terminated. Remove the memory, it was discovered that one of the cheat already burned beyond recognition, was less out of place, two points with solder points with the right to act as finger from the traces of it, should be very long and it had very poor and the person’s welders to meet the trouble. The author’s friends on principles of computer hardware basically do not know how to do such a thing? only conclusion when businessmen bought the machine to the pits, and shoddy. However, even the memory of this miracle took so long to go wrong, it makes it confusing.
A time when memory prices, so while my friends from bleeding. In retrospect, computer hardware is precision products, although the major problems in the event of certain techniques can be repaired, but the limited conditions and capacities of individuals, generally can not be repair the damaged components, such as the new. so I once again remind our friends that when the 10 million note purchase inspection carefully to avoid perpetrating a fraud by some unscrupulous businessmen, shoddy.
Fault 3: The use is not compatible with the motherboard CMOS memory caused initialization failed, unable to boot.
Day, an acquaintance calls for help, saying that more than two months to buy the machine suddenly a problem, not start. He’s configuration is: MSI K7Tpro, Thunderbird 750, PC150KingMax128M, Gainward Geforce2MX Gold Edition, IBM Dragon II 30G, Star of the Century Silver Edition power. After the boot to open the case and found the motherboard all the four D-LED indicator light is red. under the motherboard manual, this time on behalf of CMOS self-test initialization failure or CPU failure.

Because AMD’s K7 series CPU core is extremely fragile, due to fan buckle too tight, improper installation, damage caused by the CPU and more numerous. I will remove the CPU, after careful observation showed no damage. Start again after the fan is installed, failure remains. At this point, I believe that is the motherboard’s BIOS is corrupt, but did not give up, follow the graphics card, memory unload all, want to make sure. When turned on, the host PC speaker sound alarm to issue long, suggesting that the memory test failed. observation post found that second D-LED light turns green. shut down, plug in KingMax memory. then boot, D-LED lights all red. got a plug in the machine of modern 128M memory, troubleshooting. culprit, one of those KingMax PC150 128M memory, PCB version 1.1.
After After inquiry, that this version of the memory compatibility of poor, especially in the motherboard with the KT133 with use, there are much more likely not compatible. This is one case of individual differences caused by the incompatibility phenomenon, but not each other compatible with the phenomenon only occurs after the use of more than two months, until all normal, this situation is rare. The final solution is to return the post business, in exchange for one of KingMax PC133 memory. So your friends purchase, please fully understand their needs, do not easily believe that the recommendation of business, so as to ensure their machines less problems.

Pentium 4 motherboard set of common failures and p

admin — Fri, 03 Sep 2010 03:09:30 +0000

Pentium 4 motherboard Common Faults and exclusion program set (1)
phenomenon of a fault in a LandTek Han Wei LH-8ICX Pro P4-level motherboard to install Windows XP operating system, the initial phase of the installation, the computer screen suddenly the emergence of a black rectangle, then the computer stopped installed.
Solution 1 This is a virus-related tips. In LH-8ICX Pro motherboard manual referred to in the BIOS to prevent boot sector virus function, estimated with this. into the motherboard BIOS settings, find BIOS Features Setup (BIOS feature set) in the \prohibited), the re-install Windows XP, it passed.
fault phenomenon 2 1 i845 chipset using Transcend TS-ABD4 motherboard, install Windows 98 Second Edition operating system and found that the operating system can not correctly identify i845 chipset, so the system can only work in running a conservative in the default settings.
Pentium 4 motherboard Common Faults and exclusion program set (2) solution 2, because most of all because of this failure is not installed with the motherboard attached The Intel Chipset Software Installation Utility driver motherboard due. This program can correctly identify the user’s operating system to the i860 from i430TX a chip between any group, and it will automatically install the INF file to identify the appropriate recognition and support all of the features of the chipset. After the installation of the operating system, followed by installation of Intel Chipset Software Installation Utility program, the operating system can correctly identify the i845 chipset has.
fault phenomena 3 1 Gigabyte GA-8IDXH with the P4 computer, sometimes not properly shut down. specific performance for the shutdown will hang or restart, into sleep state after the situation appears not wake up, only to restart the computer.
Resolution 3 of this situation mostly due to the motherboard BIOS The Power Management Power Management settings are wrong, or the setting of the operating system does not match due to the power management settings. can first try to reset the motherboard BIOS, and ensure its consistent operating system power management settings. If the problem still, please go to GIGABYTE’s website (www.gigabyte.com.tw) up to download the latest motherboard BIOS, and upgrading. If the problem still remains, it can only be to repair the motherboard.
Pentium 4 Motherboard Fault and exclusion program set (3) 4 1 P4 motherboard failure phenomenon can be identified to support ATA/100, hard drives and the signal line also supports ATA/100, and also install the corresponding ATA/100 driver, but the system self-test Shique only show support ATA/33.
Jiejue program 4 causing such situation may be two reasons. 一是 signal line fault because of hard drive, but falling short will lead to a working connection to try what can Huan one line; Second, because the 80-pin connector reversed due to the hard disk. If the user when installing the hard drive cable connector 80-pin hard disk drive on the receiving end of the blue, the black side received the motherboard, this failure phenomenon occurs . a change in the location of wiring can resolve this problem.
5 a failure phenomenon using the MSI MSI 845 Pro2 P4 computer every time you start, will have a \, and then everything runs normally, and no other phenomenon.
solution motherboard BIOS is set to 5 improper. first of all understand \, this function is switched automatically when one of the indicators on the computer to detect the problem if there would be prompt to the user. In these Jiance the first one is the voltage detection. When the computer power supply output voltage is higher than the CMOS in set of values, they will appear above the \The option is turned off on it

Motherboard Troubleshooting of 24 cases of common

admin — Fri, 03 Sep 2010 03:09:06 +0000

1, no show boot class fault
【Example 1】: motherboard does not start, boot no display, alarm with memory (\more common, mainly caused by poor contact memory. For example, non-standard memory, memory a bit thin, when the memory into the memory slot, leaving some gaps; memory cheat poor technology, poor cheat the surface of gold , over time, cheat gradual thickening of the surface oxide layer, resulting in poor contact memory; memory slot the poor quality of the reed contacts with the memory of the finger is not really so.
approach: open the case, with rubber carefully wipe the memory clean and cheat, to take down the memory re-insert a little, hot melt adhesive on both sides of the memory slots filled the gap, to prevent the continued use of the process of oxidation. Note: In the swap memory Be sure to unplug the power cord off the host, to prevent accidental burning memory.
【Example 2】: motherboard does not start, start no show, there are graphics alarm (two short of a long tweet)
Fault: General graphics card is loose or damaged. approach: open the case, the card can be plugged in again. To check the AGP slot is a small foreign body, otherwise the card will not plug in place; for the use of voice alarm board, should be carefully identify the contents of voice prompts, and then solve the corresponding failure based on content.
If the above approach is also after the alarm, it could be bad graphics chips, replace or repair the card. If the boot, then hear the \self-test passed, but that did not display the normal image to the card inserted in the other motherboard, use the normal, that is not compatible graphics card and motherboard, graphics card should be replaced.
】【Example 3: Motherboard does not start, boot no display No alarm sound
failure reasons: There are many reasons, mainly the following.
approach: for the following reasons, one by one rule. ask you familiar with the digital circuit analog circuit, will use the multimeter, and sometimes needs the DEBUG Card check failure.
(1) CPU issues
CPU is not powered: multimeter test CPU can be used around the three (or a) field management and three (or a) rectifier diode, check whether the damage CPU .
CPU socket pin with missing or loose: the performance of such failure is not light or occasional crash point. need to open the surface of the superstructure of the CPU socket, carefully observe with your eyes if there is a deformation of the pin.
CPU socket fan fixed clamp fracture: to consider use of other fixation methods, generally do not replace the CPU socket, as easy to stay hidden faults manual welding. SOCKET370 the CPU, the radiator fixed by CPU sockets, if the fixed spring too tight, demolition Be careful when otherwise they will break plastic clamp, there is no way a fixed CPU fan.
CMOS settings in CPU frequency does not: as long as you can clear the CMOS solution. Clear CMOS jumper on the motherboard of the lithium battery generally near its default location is usually 1,2 short, just change it jump a few seconds for the 2,3-circuit can solve the problem, the old motherboard for the past, such as can not find the jumper, as long as the battery removed, boot into the CMOS settings to be displayed after the shutdown, the battery can be installed up to CMOS discharge.
(2) motherboard or expansion card expansion slots because there are problems
motherboard or expansion card expansion slot problems, leading to plug graphics cards, sound cards and other expansion cards, the motherboard does not respond, thus creating a no show boot. disassembly AGP graphics cards such as brute force, leading to cracking AGP slot, you can cause such failures.
(3) memory problems motherboard does not recognize the memory, memory corruption or memory does not match: Some older motherboards more selective memory, motherboard does not recognize when plugged in the memory, motherboard will not start, and even some motherboards do not fault tips (tweet). Another If the plug in different brands, types of memory, and sometimes lead to such failure.
memory slot broken needles or burning: sometimes because of excessive force or improper installation methods, will be a memory fault the reed beds , so that the memory slots scrapped. Note: Plug memory should be the vertical force, not from side to side. in memory before the swap, be sure to unplug the power console, use the STR function to prevent memory live, burning memory section. Also, do not install anti-memory, and to avoid burning memory after power up. But now the motherboard, generally foolproof design, not INSERT.

Fault handling all Raiders board

admin — Fri, 03 Sep 2010 03:08:31 +0000

All components in the computer, the motherboard is to determine the overall computer system performance is a key component, a good board can play a more stable computer system performance, otherwise, the system will become unstable. Motherboard itself, the failure rate actually not very high, but because of all the hardware architecture and software system environment is take this piece of board, and many of our cases also with the message board to determine the existence of other equipment failures. so to master it, you mm solution will find ways of computer failures on your side!
one boot self-test and boot the computer fault handling
favorite friends will know, the computer boot process is a very complicated process. In our press Next start button, the supply voltage is unstable, and board control to the CPU chip set will send a RESET signal to the CPU initialization. When the power supply stable power supply, the chip set will be removed RESET signal, CPU immediately from the address FFFF0H Department started instruction, the address in the address range of the system BIOS, Award BIOS, whether or AMI BIOS, put here only one jump, skip to the system BIOS boot code in a real office. the system BIOS boot code First of all do is to POST (Power On Self Test). POST main task is to test the system in the presence of some key equipment and ability to work, such as memory and graphics cards, etc.. If this time is not given speaker system soon as crisp a \The specific significance of sound as follows, for reference:
1 short: System normal start
2 short: General error, please re-enter the CMOS SETUP option set incorrectly
1 long 1 short: RAM or motherboard error.
1 long 2 short: Monitor or display card error.
1 long 3 short: Keyboard controller error.
1 long 9 short: board Flash RAM or EPROM error, BIOS damage.
repeat length affect: memory is not plugged in tight or damaged.
kept sound: power, monitor and display card is not connected.
repeating short ring: Power problems
If the BIOS self-test there is no problem Most computers boot screen will have two or three screens, the first screen for the graphics-related information, such as manufacturers, graphics chip type, memory capacity etc, if the card information shown here is different nominal target , then the card is likely a problem. The second screen shows more information with memory self-test value, BIOS information (system BIOS, type, serial number and version number, etc), motherboard information codes, quality problems if the memory , will prompt here. Third screen half of the box on the screen will display the computer’s main configuration, the following equipment will be displayed in the PCI slot IRQ and other information. If all is well finished third in the display screen after screen Start the operating system. then there can not be the most common is the start can not find hard drive failure. In addition to poor access to outside lines, the general could not find the hard drive is largely attributable to the hard disk physical damage, but sometimes have suffered hard disk master boot information is the reason the virus caused damage.
addition, since the CPU heat is very large, many motherboards offer a strict temperature control and protection devices. General CPU temperature is too high, or motherboard temperature monitoring system in the failure, the motherboard will automatically enter the protected status. refuse to power-start, or alarm. often due to the motherboard temperature monitoring line of off, which led automatically to protect the state board refused to increase power. So when your motherboard not start or alarm when first check the temperature monitoring device under the board are normal 才对. it is a CMOS RAM may be a problem because the CMOS RAM can not maintain our personal, so the proposal back to original 处理.
boot after the Ti Shi \; CMOS Battery State Low \electric iron re-welding on a new battery can. (2) button-type battery: Direct replacement. (3) Chip: This chip is best used to replace the same type chip replacement. If, after replacing the battery time is not long, there also phenomenon, then, is likely to be board leakage can check the diodes or capacitors on the motherboard is damaged, you can also use an external battery jumper.
2, motherboard components and interface damage
board the plane is a printed circuit board PCB plate, covered with slots, chips, resistors, capacitors and so on. of any components are damaged motherboard is not working properly. such as a chip on the motherboard, the general non-integrated motherboard has two chips, one is the South Bridge chip, a Northbridge chip is. If the North Bridge chip is broken, CPU and system, the exchange will be the main interface problems. southbridge chips if there are problems, the computer will lose the disk controller functions, and no hard drive that is no different than the . can see how important these two chips! burned if the two chips that were fatal, but unless the original back to repair. If the board is more integrated in trouble, because it has only one chip, and if bad the board than the general problem worse. Another example is aluminum electrolytic capacitors on the motherboard (usually around the CPU socket), its internal use of the electrolyte because of the time, temperature, quality and other reasons, will make it happen \; aging \; the replacement can be. If the OZ not been the best business for blocks to find a new motherboard, because, though small, is quite cumbersome to solve. well, if power quality is not good, or other accessories are often caused by short circuit fire resistance. This failure to judge, of course, repeatedly checking to see if the plugs and sockets are skew, resistance, capacitance pin is bumped, the surface is burned, the chip surface is cracking, whether the burning of copper foil on the motherboard off. but also to see if a foreign body between the components fall into the motherboard. encountered areas of doubt, the amount of what can make use of multimeter. touch the surface of some chips, if abnormal hot, try a chip can be changed.
There is also not appropriate because with electric plug, often causing damage to the interface board. such as hot plug the printer due to damage caused by the parallel port on a lot of trouble, not going to change the motherboard in the premise, the solution: First, find one with the chip-level maintenance capability of the manufacturers maintenance; 2 is to add a multi-functional card.
3, motherboard compatibility and stability of the compatibility of motherboard failure
we often fault is one of the problems, such as can not use large-capacity hard drive, can not use certain brands of memory or RAID card, do not recognize the new CPU and so on. the main cause of such failure: first, its board of materials and work problems; second motherboard BIOS problems by upgrading the new version of the BIOS generally will be able to resolve.
motherboard failure is the stability of the more common, such failure is due to component malfunction, the circuit breaker, short circuit, the phenomenon of stability of its repeated failure, rather than stability failure is often due to poor contact, components degrades the performance of the chip logic function is sometimes normal, but not normal when the critical state caused. such as I / O slot deformation, resulting in poor contact display card with the slot so that shows the error status was uncertain. There is also a problem can not be ignored because the motherboard overheating and cause the system to run unstable.
type failure generally occurs due to a problem or motherboard motherboard Cache caused by bad design of heat, the author 815EP motherboard in a brand, once found not good enough for motherboard cooling caused by the fault. touch the CPU after the crash around the motherboard components, found that the temperature is very high and hot. replace the high-power fans, the crash failure is resolved. For the Cache has the problem of fault, you can enter the CMOS setup program, you can smooth the Cache problem after the ban, of course, Cache ban would certainly affect the speed after the.
In addition, the maintenance of the motherboard can not be ignored, the dust is board one of the biggest enemies of the dust may cause board suffered a fatal blow. We should open the case on a regular basis with a brush or vacuum cleaner to remove dust on the motherboard, also, some card board, chip pin form, often because of lead oxide The connection is bad. eraser to the surface oxide layer can be used to re-plug. there is a sudden power-down, you should immediately turn off the computer, so as not to suddenly call the motherboard and power supply burned.
4, chipset and operating system the compatibility of the
we all know, the upgrading of motherboard chipsets faster and faster, the new chipset series of problems arising placed in front of us. like a lot of motherboard chipsets that can not be the operating system correctly identified, it could have been a direct result of the new technologies to support the normal use and compatibility of Wen Ti Bu Neng large numbers. Microsoft Yezhuyidao the current situation, they came up with some solutions. For example, Win2000/XP Xitong upgrade package Chule solution safety, the specially integrated set of Qu Dong Zhu Duo chip process, solve Bushao performance and compatibility issues. However, Microsoft Zuo’s Zhexie only a limited effort, for a number of technological developments remain unable to Zhichi. Women pay more attention to Yixiazhuban Bude Bu driven by the chip set that companies give us, the operating system’s \and performance does not seem to directly link Is that true? In fact if you do not install a patch is likely to lead to sound card not working properly, the graphics card driver not properly installed, the hard disk will not open DMA mode, enter the energy state after such failure can not wake up.
compatible chipset for VIA, etc., its 4-in-1 patch, proper installation is particularly important. VIA 4-in-1 drive is included to meet the interface specification for IDE ATAPI devices available Driver, AGP VxD Driver (virtual device driver), IRQ (Interrupt Request) routing port driver and the VIA INF (driver information). In addition to the compatibility problem outside, VIA 4-in-1 drive can achieve and Intel provides several driver programs similar functions. because compatibility problems will increase as new products for increased, performance Youhua based simultaneously on the 考虑, VIA 4-in-1 driver program updates Bijiao frequently. But you Zaiyingyongzhong Ru Guo did not suffer the problems will not need to always update to the latest version of the 4-in-1 drivers.

Windows operating system common drive failure solu

admin — Fri, 03 Sep 2010 03:07:59 +0000

driver is a basis we use the operating system, without it, we can not hear sound, not see the picture, unable to get online. If the driver out of trouble how to do? topics we often reinstall drivers , but some faults may be you do not think is caused by the driver. Now we gave you about some of the drivers often encounter failure analysis.
Basics: How to actually do the problems in Device Manager Symbols
在 Windows operating system, device manager is a management tool for computer hardware equipment, we can see the computer with Device Manager in the Anzhuang of hardware devices, Shezhi equipment Zhu Xing, install or update the driver, disable or uninstall the device, you can Shui is very powerful.
On the desktop, right-click \shows the local computer to install all the hardware devices, such as optical storage devices, CPU, hard drives, monitors, graphics cards, network cards, modems and so on. Here, I introduce to my friends in the Device Manager, some of the issues symbol.
1. Red crosses
For example, you see the \do not often use the 1394 device and the PCMCIA card, to save system resources and improve the startup speed of consideration before the equipment is disabled.
Solution: Right-click the device, from the shortcut menu, select \2. Yellow question mark or exclamation mark
If you see a device that was displayed before the yellow question mark or exclamation mark, the former indicates that the hardware could not be recognized by the operating system; which means that the hardware is not installed drivers or drivers not installed properly.
Solution: First, we can right click on the hardware device, choose \some cases may need to insert the driver disk, please follow the prompts.
1, sound card
1, Windows prompts did not find the hardware drivers
Such failures are generally due in the first loaded driver is not properly completed, or in the CONFIG.SYS, automatic batch file AUTOEXEC.BAT, DOSSTART.BAT file has been running for a sound card driver, which can be which run a driver file can be deleted, of course, you can delete the three files mentioned above to solve the fault. If the above three documents which have no documents, and the driver, he will not go in, this need to modify the registry, click the \table entry \There is also a most simple way is the sound card into another slot, re-found a new device, load the driver can solve the problem. Although the second method seems simple, but we still follow the first solution software fault the principle of hardware is appropriate, just before carrying out the first method the user the best guide them back up the registry first look in case of emergency.
2, the old sound card driver cause system failure
Failure phenomenon: an old machine recently installed Windows XP system, the installation process is smooth.’s Windows XP system is the large memory consumption, but also installed a second hand 128MB SDRAM memory to make the system run more smoothly more. But Soon the question came: the system during operation of frequent crashes, particularly in the QQ chat online and the most frequent fault.
Analysis solution: installed very smoothly because the system is not the result of installing the secondary memory malfunction? So first remove the piece of memory failure after reboot still. In order to exclude application software and system conflicts, so reloading the system, but the failure still. taking into account the age and the power adapter failure can also result in a similar situation, to be replaced after the failure were not excluded. is now very hot, is not caused by bad CPU cooling phenomenon hang it in the BIOS to detect CPU temperature lasted no more than 46 ℃ eliminated a suspected bad CPU cooling. Finally, the problem seems to be concentrated in the motherboard and hard disk. update of the new Seagate hard drive 20GB, there should be no problem, after system testing has proved this point. Could that be a motherboard driver too old and the new system is not compatible with Windows XP? Internet trying to find a new motherboard driver updates, not found, but discovered by accident onboard ACr97 new sound card driver, although the sound card has been working properly, but also the way to first try to download . Remove the old sound card drivers, install new drivers reboot, troubleshooting. originally the old sound card drivers, resulting in and Windows XP compatibility is not good enough cause system failures.
3, after the completion of the sound card driver into silent
First of all, to see the sound card and speaker wiring is correct, speaker of the signal line should access the sound card’s speaker or spk port, if the wiring is correct and then go to Control Panel’s multimedia options, look inside with or without sound equipment, describes the equipment, the normal sound card drivers loaded, or driver is not successfully installed or existing equipment conflicts, should the existing equipment can be pressed method to solve the conflict:
1) what sound card replacement socket (in my experience, the sound card, MODEM and other expansion card into two, three, four, five slots better as a tank generally will result in conflict with the graphics card).
2) resources into the sound card setup options to see whether its resources have not changed the address or interrupt conflict.
3) The reservation of resources into the project to see whether the sound card to retain the use of resources to prevent other devices.
4) to see whether the sound card can change the interrupt jumper mouth.
5) Close the unnecessary interruption of resource consumption, such as ACPI function, USB port, infrared and other equipment.
6) Upgrade sound card driver.
7) into motherboard drivers and try again. In the above-mentioned option in any multi-media audio device, but the silent sound card, sound card volume control to enter the menu if there is a muted, there is a kind of special situation, some sound card drivers must be installed within the SETUP, it first COUFIG and AUTOEXEC, BAT files, create some of the sound card driver file, under the WINDOWS to the normal place (such as 4DWAVE sound card).
4, ACr97 sound card driver failure and treatment
Failure Analysis: On the desktop task bar represented the voice of \I open the \; resource item there is no interruption of the conflict, \folder \ sound \ adi \ soundMAX \ 188X \ win95, and copied to the local hard disk, and then implementation of the folder of setup.exe to install. the control board observed that this section does not use the 188X series motherboard soft sound card, instead of using the VIA their ACr97 sound card, speakers do not seem to speak out because of errors caused by sound card driver installation.
Troubleshooting: I in the \AC97 PCI Sound Drivers \, is set to \\\selected driver is not selected specifically for the hardware design, and may not run hh Select \\on the correct drive, failure to lift.
5, Windows XP and innovative sound card driver conflict
This may be caused by Windows XP’s driver problems Yinqi process itself of. Because the innovations did not release the sound card drivers in Windows XP 下 procedures, but 由于 Windows XP is Windows 2000 Fa Zhan You come in, we can use The sound card in Windows 2000, instead of the driver, so that can always be solved.
6, the wrong sound card driver installation failure caused
Failure phenomenon: after reinstalling WinXP system, the first turn on the TV card to watch TV programs when the program, the normal sound card can sound, but switching to other channels, the TV program was very quiet. Quit after the procedure to re-open the TV No. can only restart the computer, watching TV, when can we have sound, but as long as the channel after a conversion program to continue to repeat the failure. Moreover, this failure only occurs when using the TV card, the failure occurred before and after play other multimedia files, audio sounds can be normal.
Troubleshooting process: As the TV card is through an audio cable to connect to the sound card’s line input, it can sound when watching TV, I first pulled this audio cable, speaker received directly to the TV card audio output, the result sounds normal, that is, excluding the TV card’s sound output problems, but after replacing the cable, the problem still remains. Therefore, I determine a computer’s sound card out of the question. Because there watching TV silent failure, the computer plays other multimedia files, audio can be normal voice, so I suspect the sound card drivers and TV card driver conflict, but I uninstalled the sound card driver process, the computer actually automatically restart and can not use safe mode into the system. Then I set the BIOS to disable the sound card can not start until the original sound card drivers to uninstall. uninstall sound card drivers, I set the sound card in the BIOS re-open, into the computer, automatically find motherboard drivers for WinXP program disk sound card driver, the system quickly identify the location of the driver and automatically install the sound card driver, but the fault persists.
After reinstalling the TV card driver does not work, reinstall the operating system due in until the computer can watch regular TV programs. Is not a TV card and motherboard integrated sound card is not compatible? With this question, I checked the TV card and the motherboard manual, but the instructions are written on a compatible WinXP system. The motherboard manual to write the sound card model, it caught my attention, because the motherboard manual to write the sound card model is CMI9739, and have the system automatically when installing the sound card driver , installation is ALC100 sound card drivers. In order to determine the model of sound card, I open the case and found the motherboard sound chip is indeed a CMI9739. after I uninstall the original sound card drivers, then reinstall the CMI9739 sound card drivers troubleshooting.
In general, the installation of the wrong sound card drivers, computer sound is not normal, but then I tried it on another computer and found that ALC Series sound card drivers installed, the integrated VTI612A and CMI9739 chip board can properly pronounce only occur with the TV card incompatibility. and often the operating system to install WinXP drivers for the process, we have used only point the next step, the expense of the found the system automatically select the drivers. So suggest that you install the sound card driver, the best a look at the motherboard manual, or check the sound card chip on the motherboard model.
Second, graphics
1, graphics driver failure problem
Q: re-install the operating system, it was found in the \caused by the installation of the driver, but my motherboard and graphics card is integrated, does not know the integrated graphics models.
I used the Everest software testing graphics models, but can not be detected. Then find the motherboard manual, which was written by VIA K8M400 chipset, what is the chipset graphics driver Where can I download?
A: This is a classic problem, and some hardware as too old, will lead to the identification of the motherboard, but that the board chipset model, then the driver does not become a problem.
2, no show boot
Such failures are usually because of poor contact with the motherboard graphics card problem or motherboard slot cause. For some integrated graphics board, if memory shared main memory, you need to pay attention to memory location, usually in the first memory slot should be inserted in memory. As the graphics card causes no show boot failure, boot normally issued after a long two short beeps (in terms of graphics for AWARD BIOS).
3, shows Huaping, blind writing
Such failures are generally due to high-resolution monitor or video card does not support caused. Huaping start mode when the switch to safe mode, and then in Windows 98 into the display settings, in 16-color mode click on the \\. drv = pnpdrver to display.drv = vga.drv later, save the file out, and then update the driver in Windows years.
Color display is not normal, normally the following reasons for this failure:
1). Graphics card and the monitor signal line connection is bad
2).
Display their own fault
3). In some software to run when the color is not normal, usually common in older machines, there is a check in the BIOS, the color of the option to open it can
4). Graphics damage;
5). Display is magnetized, such phenomena are generally due to the magnetic properties of the object with a result of too close, magnetized may also cause the display deflection phenomenon occurs.
4, Death
This failure will normally prevalent in the motherboard and graphics card or motherboard and graphics card is not compatible with poor contact; graphics card is not compatible with other extensions can also cause crashes.
5, abnormal noise while the screen or logo
Such failures are generally due to problems with memory or graphics cards caused by poor contact with the motherboard. Need to clean or replace the graphics card cheat site.
6, graphics driver lost
Graphics driver to load, run some time after the driver automatically lost, such failures are generally due to poor quality or the graphics card is not compatible with the motherboard, making cards too hot, leading to system instability or crashes running, this time Only replace the graphics card.
In addition, a special class of cases, graphics driver prior to loading, but loading the graphics driver after the crash when entering Windows. To change to other models of its graphics card driver in loading, insert the card to be resolved Jiu . Should the further resolve such failures, it indicates the registry failure to restore the registry or reinstall the operating system can
7, graphics driver restart caused by failure
This may be installed after Windows XP did not use its own graphics drivers, but to re-install the graphics driver on the hard disk, because the driver is Windows 2000-specific, and I think Windows 2000 and Windows XP are NT kernel-based 32-bit operating system. and some articles on before, when some dedicated graphics card, if can not find Windows XP drivers, you can try to substitute with Windows 2000/NT, although I used to run after the big Some of the programs and games, but eventually because of driving on some of the small differences caused by the above fault. seemed to install graphics driver also prescribe the right medicine!
8, install the video card and Modem driver crashes after installing sound card driver
This is because the conflict between the Modem and the graphics created. Should install the Modem driver to install the sound card to work before. If the problem persists, you can first open the case, the built-in Modem pull down from the motherboard and then install the Windows98 operating system, then install the video card, sound card driver. Then out of the operating system and shut down, the Modem plugged into the motherboard, restart the computer will be prompted to find new hardware, according to prompts to install the Modem driver, the final restart of the computer.
9, the normal installation of graphics drivers, the Resolution can only be regulated to 640X480, Why?
This may be because the Windows 2000 operating system installed on the display driver is not correct result. Resolved steps:
(1) Right-click the desktop, the pop-up shortcut menu, select \Advanced \(2) In the \Wizard dialog box appears to gradually follow the prompts to install the driver can enter.
10, a hardware conflict causes the driver can not install the most common faults
Is due to hardware interrupts between, DMA, I / O addresses, memory address conflicts caused by the driver can not normally drive after installation hardware. This type of conflict, mainly in Windows98 and Windowsme system where, WIN2000 and WINXP would normally be occurs, symptoms that all the drivers installed correctly, but the hardware is not working properly, the resource manager is out of the red crosses and yellow exclamation mark:
Such failures occur mainly due to two different hardware interrupt number to use the same IRQ, DMA request, the memory address or I / O address, such as the use COM2 serial port mouse with built-in conflict MODEM, LAN, and printers, graphics conflict and other such failures will occur. to address these issues requires a gradual process of exclusion:
The first step: first enter the BIOS to \Step two: still can not solve, try to replace PCI expansion card slot location, turn off the system without the device to release more resources available.
Step Three: If you still can not solve the problem need to manually specify the different resources for hardware, or try to update motherboard BIOS, hardware-driven program to address these failures. Please driver database to help solve the problem sometimes, to install in Windows 98/Me or update the specified hardware drivers, it does not work correctly, even try to install the driver, still OK, when you do nothing, we might rebuild Windows driver database can solve this problem.
What is a \bin file.
When the driver updates or changes, the driver information database information will also be changed. But Windows does not check the driver installation is correct. So, if you have the above-mentioned problem, you can rebuild the driver information database, remove the installation of the driver files may cause a mismatch for any information.
Here take a look at how to rebuild the driver information database:
The first step: before the completion of the update must be prepared to hardware drivers, as you remove the device, Windows restart when prompted to install the device.
Step two: enter Windows Safe Mode, press \equipment, all items, then close, if prompted to restart the computer, click \Step Three: Click the \After, right-click \Step Four: Using the third step of the way to \Step Five: reboot the system and enter the normal mode, Windows will create a driver information database, and prompts the default installation device drivers, hardware drivers into the floppy disk or specify the location to save in hard drive, then install can. After installing the driver work very unstable because the system automatically installed the hardware more compatible with the driver, or an old version of the driver is not completely clear, the hardware does not work or lead to very unstable conditions. such failures are quite common in Windows98, Windows2000, WindowsXP will always be, and because the system automatically loads the drivers, so the surface will not like the interruption of class conflict, failure noticeable error.
Used Intel810 motherboard friends all know that this board because of low prices, to make it carry the sound card chipset grades vary, ALC101, ALC201, Sigmatel 9721, ADI 1881, ESS1869, Crystal 4239, VIA AC97, etc have meant that some students hand when installing the sound card drivers, such as head of cattle, these chips from each other, \clear identification, all showed normal sound card, but that is not normal speech, normal delete the wrong drive, but after reboot, the system then automatically \, the system still will first install the driver as the default sound card driver, so that some friends had to reinstall the system, then install the sound card driver he sent pray.
So how could he complete the driver will not need to delete it? Most people will be from the control panel to uninstall the driver, or from the resource manager in the hardware removed, but only do this step is absolutely not enough system does not completely remove the old driver, you should implement the following operation.
Windows 98/Me: still need to C: \ Windows \ INF folder, delete the related INF file (can use search feature directly from the hardware name for the key words), the system can not find the inf when loading the driver installation give up the installation file.
Window 2000/XP: In addition to delete the C: \ WINNT \ INF folder on the appropriate INF file, it also requires, under the INF file to \do not delete the system will start after the wrong driver is still loaded but fail to update the drive’s purpose. incomplete driver installation failed because the driver is installed imperfect, system or driver files are missing, damaged , and caused by improper hardware-related options set.
Poor because of their compatibility with some hardware, even if the fault does not exist, will in the course of such problems, the typical examples such as the Intel845 series motherboard sound card to use most of the ALC series may be in the game appear suddenly lost sound or play video files sound the phenomenon, another example using the nForce2 motherboard users encountered such a situation, Windows2000 system, access to the desktop, or copy files, sound card will be issued a sonic boom or play off of the situation network will suddenly disconnect for no reason, these are as imperfect sound card and network card drivers cause, such incidents should prompt concern about whether, after the latest version of the driver release. \disaster before use Haohao De hardware, such as Modem, scanner, printer, when suddenly prompted the use of illegal operations (below) or garbled prompt.
Such failures were due more to the illegal shutdown, virus damage, misuse deleted, confusion and other programs cause the system file is missing or incomplete driver to solve this type of failure the system must first complete anti-virus, system files and then return to normal, such as the use under Windows System File Checker (in the \cause the hardware work is extremely relevant option also drive the hardware working properly can cause abnormal, that the performance of different hardware, different, for example, mapping the details of OpenGL graphics set too low degree of ambiguity caused by the game screen, Resolution set over caused a black screen display tolerance to NIC IP address specified an invalid network and gateway leading to unreasonable, typical of example uses the ALC series sound card for a friend Zaian Zhuang driver, SoundMAX and installed automatically at startup plus set, using the software on the computer can easily be adjusted to use the environment and monochrome, but the sound sometimes suddenly, \set result.
These operations are related to drivers the option to provide relevant, as long as careful when making exclusion View with hardware-related settings and programs, you can gradually find the source of the problem.
Third, motherboard driver
1, motherboard drivers cause the computer to crash failures
Friends assembled near the recent frequent crashes computer failure, failure phenomenon is running a number of graphics and image processing software, when disposed of the implementation of the machine would crash when saving, and this is very annoying to friends, to re-install the operating system several times After the failure still has not ruled out, and most importantly, a friend’s computer are not able to properly install the scanner, to a friend’s work is a big inconvenience.
Failure analysis and solution:
A friend is engaged in interior design, assembly of this computer is to design drawings, so the configuration of the machine is not low, the specific configuration is as follows: Elite 915PE chipset motherboard, Colorful 6600 graphics card, Kingston 512M DDR400 memory, Intel 775 processor 64-bit 506-pin (frequency 2.66G), Seagate Barracuda hard drive for the seven generations 160GB PATA, CD-ROM for the Samsung DVD-ROM, another scanner brand Thunis.
According to friends, this computer is the one assembly machine, using about half the time, one of the more stable, and no problem. There is a chance your computer is virus infected friends, installed a fresh operating system, Zhihou scanner will not work in installation, implementation of other image processing software Zai (friends often 用 PHOTOSHOP) save Jiu Chu Xian crashes frequently, Erqiemeici Zhongxin start Zaicihaishi so, Guzhang more frequently, during which friends and Meiyou on any hardware OC use.
Now that the computer re-installation in the absence of the normal operation, but often crashes after installation, which fully demonstrates the failure of hardware damage is unlikely, so I will focus on aspects of the problem on a software failure. According to friends of the introduction, running image processing software easily crash, the first is to check the version of DirectX, or whether there are problems with the equipment to support bad. open the DirectX view the version 8.1 (a friend installed the windows 2000 operating system), so on DirectX software has been upgraded, the upgrade to 9.0C version, again running image processing software, failure still.
So I doubt you can be friends mistakenly shut down or misuse the system lost a file or cause data errors caused by the registry, so I switched the computer to DOS mode and use Scanreg / restore to restore the system registry, the problem remains. do the authors really hardware problem
