Whether it is compatible device or card machines, in the course of the phenomenon will appear inexplicably crash. Death is a common fault phenomena, but also a not easy to solve difficult cases. Especially when the computer crashed after , then we can not use the software or tools to test the machine, repair them is often a headache.
1. crashes generally showed:
1) after power up without the host did not respond, the power indicator does not light the fan does not turn;
2) the system does not start during startup screen suddenly stagnant;
3) during the startup process displays a black screen or display a black screen during use;
4) image \solidification \break;
8) regular blue screen.
9) often report an error or memory overflow.
2. fault performance
Specifically, the crash can be classified into two cases of hardware and software. :
1. Hardware
hardware caused crashes often are: mains voltage instability, the host power supply output voltage is too low or too high, too high temperature within the chassis, memory, temperature overheating, CPU temperature is too high, overclocking , interference, peripheral to their own fault, poor contact card, the host and the peripheral data lines connected to poor contact, etc..
(1) electricity voltage instability
computer voltage range of typically 180V-240V room, when the voltage falls below 180V, the switching power supply output voltage is too low or protection, then reboot the host is easy or automatic shutdown; when the voltage higher than 240V, the electricity power supply input voltage exceeds the allowable scope of the host, but the circuit The discrete components, then the power may not have protection, then the secondary power output may be high, the same phenomenon can also cause crashes.
(2) the host power supply is not completely damaged
when the host power supply inside circuit is damaged, then the voltage output current output may be biased or inadequate, resulting in effective loading rate is less than this time will also have the phenomenon of Death. current mainframe computer switching power supply used in most of the use or similar TL494 PWM control chip, compared LM339 or LM393 devices commonly used to control whether to send the switch determine the host machine signal. When the chip is faulty, there will be short we lead after the green line and black line (some books require the use of 100O resistor, in fact, not necessary, the internal power supply circuit has been connected in series about a 2K resistor, even if the short circuit current, but also a few mA), power supply fan working, multimeter test voltage outputs can be normal. But the access circuit, the power can not be normal work. This is mainly damaged the chip, the voltage sample is wrong, not with a heavy load caused by Jun only by exchanging with the model Xinpian can.
I met Yi Ci, a no-name power supply, use of a year and a half so, the host often crash or not start, final inspection switching power supply, +5 V output was found as high as 5.86V, while the +12 V is only 9.9V, the power supply like this do not crash when pigs fly, okay, not the motherboard burned.
(3) the heat within the chassis of dust too bad
chassis will cause the system to hang. dust is the enemy of the computer, too much dust attached to the CPU, chipset, fan cooling the surface of these components will lead to poor or poor contact; same printed circuit board of the dust in the humid environment often leads to short-circuit. In both cases the phenomenon may lead to crashes. This situation is common in some old computers in place to open a year or two later when nothing happened after a boot or \accurate, so a boot CPU temperature is usually around 50, far higher than the detection SOCKET 370 CPU temperature (about 30). However, because PIVCPU the heat capacity, the CPU fan must be selected according to the type to select the CPU the corresponding CPU fan, do not let the small horse-drawn carts, otherwise crashes constantly.
solution: we can use brush to sweep the dust, and then hair dryer (cold air file) to the gray card sharp clean up.
Note: Do not brush and cotton swabs of wool, cotton remain in circuit boards and components become a new source on reset. If we can clean up once a year within the host and display the dust, our love machine would not have no reason to strike up.
(4) DIY overclocking
many friends like to improve your computer by overclocking performance, so you can spend less money and more things. but there are big problems: light is caused crash, may cause heavy CPU, memory, hard drive completely scrapped.
overclocking once I have the experience, the 66 super hard on the motherboard FSB FSB 83, just started working well, when I I was a small trial for their complacent when the chopper, two days later, suddenly in the running, the system can not find the hard drive tips. At first I did not care, then more and more frequently, in the end could not find any hard drive in the CMOS . especially now P4CPU increasing its integration, and some have used 0.09-micron line, when we use overclocking, it is likely to cause excessive CPU within the electronic attenuation, the final link line completely broken, causing CPU scrapped.
(5) error
motherboard jumper FSB and multiplier, some motherboard using the line or pull code switch, CPU or memory, choose to use the power supply voltage jumper settings, then we have to follow the instructions to set the corresponding main CPU frequency multiplier parameters and the corresponding use of voltage. If the set does not cause the CPU overclocking potential, set the parameters too high, you may enter the system on a black screen or a crash. Sometimes we in the CMOS jumper after discharge did not jump back to the original position, then it will start at power-black does not start. Some motherboards support both SD and DDR 2 kinds of memory, attention selection jumper on the motherboard are +2.5 V and +3.3 V are two voltage settings. particularly CPU The core voltage setting a not an error, or easily cause CPU scrapped.
(6) peripheral damage to the internal circuit when the peripheral
such as displays, printers, M damage the internal circuitry, and then connected with the host would short-circuit the corresponding port, then when the host can not power up self-test or cause power protection. Some cutting plotter, the editor earlier in the host after power up, then the host can not start after power up.
(7) and the peripheral data lines connected to poor contact.
peripheral and host a loose cable connection, they may cause the data during transmission interruption or error, it will also cause erratic crash the machine.
(8) hardware, poor quality or counterfeit goods, parallel imports.
hardware quality, but hard, work long hours or work in the ambient temperature is too high or too low, there will hang phenomenon. In particular, some computer REMARK products installed in your computer troubles, it is best to check to check also can not find the problem, the best time to consider not buying the goods of the JS.
some time ago, many Barracuda 40G hard drive, buy a house less than a week, it appears bad sectors. and then FORMAT after the normal, but over time the fault occurs again, then more and more serious, and sometimes inexplicably lose the data.
(9) accidental damage during maintenance
our body does not discharge static electricity or lightning current to pass through the protection of the power and telephone lines into the host MODEM, damaged power supply, motherboard, MODEM, and various internal and external equipment . accidental damage to the surface after the components are sometimes not obvious burn, crack trace, then only through the exchange, swap testing the various components of the host to determine good or bad.
(10) interference
are now at home There are many household appliances, especially of inverter air conditioner, washing machine, cooker, etc., these appliances will work to the large amount of electromagnetic radiation in the air, if the computer is nearby, it is also possible the phenomenon of unexplained crashes or blue screen. Then We’d better computer for a place to try.
(11) damaged or incompatible memory
when bad blocks occur when the internal memory or the motherboard’s compatibility with the bad, will always appear: Registry Error , memory error, blue screen, system resources, then hang.
now host of features more convenient, such as a keyboard boot, boot password, STR and other work. But the more features, the likelihood of its failure greater. in particular STR function, the function when the machine is open, we choose to sleep, then put the current system settings stored in memory, then the rest of Dian Lu closed, only the work and memory Vice Dianyuan related circuit. during sleep, memory constantly refresh the content of which is not lost. But if in summer, because each memory power probably around 20W, long sleep, it will cause excessive heat build-up, Powder does not go out, and finally burned to the host power supply or memory.
2. Software
software failure caused a lot of crashes, such as virus, driver installation errors, the driver or other software conflicts with the system, CMOS settings wrong CONFIG.SYS or AUTOEXEC.BAT configured incorrectly, WIN.INI or SYSTEM.INI file to load the file is missing or damaged, loaded too much, too little system resources such as surplus.
(1) virus
generally showed the normal machinery of the original first run, a sudden run on slow, crashes frequently occur phenomenon. then we must first of all with the latest antivirus software, virus, to determine whether the machine has been infected with a virus. Computer viruses are now emerging, modes of transmission tend to spread through the network, so we in the Internet, be sure to install the network anti-virus software, and some commonly used ports are not open to close.
(2) driver installation error < br> hardware error or hardware drivers installed its own driver BUG, the phenomenon can also cause crashes, then need to check the installed drivers for the hardware if the hardware model or models to match the core chip. If you can, to download the latest drivers for the hardware.
(3) CMOS setting error
CMOS contents, such as CPU frequency, multiplier, memory refresh time, L1, L2 is open, ECC check or even Check ,15-16M, etc., the above, setting error, the host will feel significantly slower processing speed, and finally crashed.
When the CMOS settings in the \function is open, we install the software process WIN9X crash will result in the phenomenon, because then the system prevents a program guide to the main zone and zone C BOOT disk write commands.
CMOS parameters due to frequent changes, or viruses CMOS parameters on the damage, often leading to confusion and difficult to restore CMOS parameters. can be used on the CMOS discharge method and using the system BIOS settings to re-set the CMOS default parameters. CMOS to discharge, refer to the motherboard manual for. Zhong based CMOS parameters After the virus must also be on the hard disk can be whichever
on the CMOS default settings, such as \
if the software crashes during the installation or after you install the software after a crash on reboot, the system is generally installed in some configuration and software do not match. then you can try on the CONFIG.SYS and AUTOEXEC . BAT in the driver settings related to modifications.
of the CONFIG.SYS and AUTOEXEC.BAT can also press F5 to skip the startup system configuration file or click F8 to step through CONFIG.SYS and AUTOEXEC.BAT select the option to check that a driver or load documents, in particular, EMM386 on EMS, XMS configuration, we may use this to determine the causes;
some hardware drivers and memory-resident programs you can do not load their way to avoid conflict.
for WIN9X operating system no longer needs the support of the above two documents can normally start the system, these two documents is mainly to retain the original DOS program support and compatibility.
(5) WIN.INI and SYSTEM.INI file to load the file is missing or damaged.
if the WIN.INI and SYSTEM.INI files that need to load the damaged or lost in the system boot process Only time will arise in the blinking cursor, keyboard, mouse, did not respond. but most of the tips there is a certain file can not be found. then we can suggest to retrieve the file or files in WIN and SYSTEM in the appropriate option to delete.
If suddenly there is a system can not boot after boot, then we can use SCANREG / RESTORE command to restore the registry to try one day.
(6) software has conflict or not compatible with the operating system’s applicability
more convenient, its procedures and directives are increasingly large, running different software is not compatible There are some places do not. Sometimes the initial version of the anti-virus software there may be in the design of small BUG, it will appear when the user installed the host can not shutdown, system start slow, blue screen of death issues. At this time we only put off or uninstall the software on it. the criterion is that if the installation of a software system is working properly, and when installing a software system is not normal, then the problem is definitely caused by the software.
(7) loaded too much or too little system resources
start if the host configuration is too low or too large applications, it will also produce the phenomenon of Death. Then in My Computer properties, select the \twice as much physical memory or more. address the main method or under the machine’s configuration, select the appropriate application software.
(8) network problems
Sometimes the network can also cause crashes abnormal phenomenon. now popular The Lianzhong, Legend and other online games, if the network is not normal in the course of communication with the server will also have crash phenomenon. Some of the performance of crash course in the Internet, and some showed dropped after the crash.
3. solve Methods
computer failure to meet the basic principles: first, after the hard-soft, after the first addition, the first from the main post, the smallest system, replacing one by one.
4. example
(1) a host Lenovo PII400 In Rising antivirus software installed, start slow. open an application, such as the WPS2000, had to spend 30 minutes. careful testing, not only open the application software for a long time to print a document using the printer, print an A4 paper, would take nearly 10 minutes. analysis of the situation before and after the fault occurs, and finally uninstall the antivirus software Rising, the system returned to normal.
**** new listings this year, antivirus software 2003 instability still exist and incompatibilities, often blue screen after installation or freezes.
we install anti-virus software, best software installation intact, and finally re-installed anti-virus software to minimize incompatibilities or conflicts arise .
(2) a PIII800 host, a small compact chassis, 7-8 months each year, often a sudden shutdown, then boot invalid. have to unplug and then plug in a few seconds after the boot outside to start. This failure is mainly because the chassis is small, narrow interior space, combined with the use of more than a year later, excessive dust, poor air flow, leading motherboard, CPU, power supply heat dispersion does not go out, the final result in power protection or Death . Finally open the case, after the dust for the CPU and power supply troubleshooting.
(3) a CII566 host, just a good machine installed in a computer company, one into the customer’s office, not take half an hour on the Blue Screen of Death . this problem to the customer from the company’s office several times and from, are normal in the company, one to the client’s office in the crash. the last inspection found that the top is a computer at work the air conditioning. Finally the computer is removed After a certain distance air conditioning, troubleshooting.
(4) a PIV2.0 machine, the customer just bought a home not two days, three hours of sleep after use, regardless of how the keyboard, the mouse can not wake up. This the problem is that the user inadvertently CMOS settings STR function open (set to S3), and then use the sleep, leading to power supply overheating. Finally replace the power troubleshooting.
(5) a P166G brain, the installation End RealPLay, the system prompted reboot, the blue and white when there is no response after a longer. This issue may be 166MMX software installed on the machine and RealPLay software conflict or a lack of RealPLay software required documents, resulting in crashes when you start phenomenon. Finally enter the security model, the RealPLay uninstall, you can start properly.
Blue Screen of Death crash Imperative why it
operator vexing issues, often to work the WTO. Death to the show more for the blue screen, can not start the system, the screen \not from reason never hardware and software aspects. Haohao De machines have been running frequently to put a blue now face, people uncomfortable. This brief blue screen of death caused a number of common causes and solutions.
1 , have a hardware failure caused the crash
1. computer overheated loss: monitor, power supply and CPU heat in the work of a very large, so good ventilation is very important, will result in overheating if the display color, image distortion or reduced display life. long working hours can lead to poor power supply or monitor heat caused by computer crashes, may wish to price a high-performance CPU cooler.
2. Mobile inappropriate: the computer move the vibration process under great device inside the machine will often loose, leading to poor contact caused by computer crashes. Therefore, when the mobile computer should be avoided shock.
3. dust wash: the machine components if excessive dust contamination, such as the head, resulting in time write error, a serious cause computer crashes or damage to components, so to keep the air clean, if necessary to remove the computer too much dust.
4. device does not match: If the motherboard and the CPU does not match the frequency is too high and too low can cause frequent crashes. At this time, the situation can change according to the appropriate hardware.
5. hardware and software are not compatible: If running Photoshop, AutoCAD 3D animation, graphic design software, effects on different hardware devices will vary and may cause crashes. We can choose according to the actual situation of the corresponding hardware or software.
6. memory failure: main memory loose, Weld or memory due to the core quality. under the circumstances of exclusion memory access fault, if the memory should be replaced by quality problems.
7. hard disk failure: the main hard disk aging or due to improper use bad sectors, bad sectors. so easily occur in the operation of the machine crashes. less serious, can be ruled out with special tools, the more serious can only replace the hard drive of.
8.CPU overclocking: Overclocking improved CPU, the same time, its performance becomes unstable. The reason CPU in the memory (RAM) access data faster than the speed of the already exchange data memory and hard disk speed, overclocking make it more prominent conflict, exacerbated in memory or virtual memory can not find the required data in the case, it appears \device interrupt, DMA or port conflict, then, may lead to the driver an exception, so that crash. The solution: a \adjustment, the general can be solved. For an exception in driver error condition, you can modify the registry. Select \\0.5-1% in hard drive capacity. so it should be put on the largest possible memory capacity.
11. using inferior components: a small number of unscrupulous traders in a customer assembly compatible, the use of poor quality cards, memory, Some even sell counterfeit REMAEK off the motherboard and CPU, memory, this machine is very unstable in the run-time, inevitable crash occurred. Therefore, users should purchase their own eyes brightened, preferably with a knowledgeable staff , and using some new tools (such as HWINFO, NORTON, etc.) test the computer for a long time continuous test machine (such as 72 hours), and the warranty for as long as possible time.
Second, the software causes crashes < br> 1. HIV infection: the virus makes the computer’s efficiency declined sharply, causing frequent crashes. At this point, we need to use antivirus software, such as KV3000, Kingsoft Internet Security, Rising, etc. to conduct a comprehensive virus scanning, anti-virus, and do so regularly update anti-virus software.
2.CMOS set incorrectly: the fault is common, such as hard disk parameter settings, mode settings, memory parameters set incorrectly causing the computer can not start. if the non-ECC memory function is set to ECC feature, which will cause crashes due to memory errors.
3. delete system files error (or error): As the need for Windows 9X start Command.com, Lo.sys, Msdos.sys and Drvspace.bn four documents, if These files have been damaged or accidentally deleted, even in the CMOS settings are correct in a variety of hardware did not help. Workaround: use the same version of the operating system boot disk to start the computer, and then type SYS C: both.
4. initialization files to find damage: Since Windows 9X start to read System.ini, Win.ini, and registry file, if it exists Config.sys, Autoexec.bat file of course read. as long as there is an error message of these documents Death can occur. In particular, System.ini, Win.ini, User.dat,
System.dat these four documents is particularly important.
5. dynamic-link library files (DLL) is missing: in Windows operating system There is also a class of documents is also important, and this is the extension DLL The dynamic link library files, speaking from the nature of these files are shared class file, a DLL file at run time the software will be more need to call. If you delete When a number of applications, the software installation program records the documents it had installed and ready to be removed one by one, then it is easy to delete the dynamic-link library files there is also need to call other software run-time situation. this produced a software error. If the missing-link library file is more important core linked file, then the system will hang or crash. 6, hard disk space too little or too much debris: If the remaining hard disk space too small, because some applications run requires a lot of memory, so need virtual memory, and virtual memory is provided by the hard disk, so the hard disk have enough free space to meet the needs of virtual memory. while also training regularly defragment your hard disk, clean hard drive good habits of waste paper.
7, BOOS upgrade failed: backup BIOS in case of emergency. If your system BIOS upgrade needed, then determine the best before upgrading the BIOS version you are using it with your PC consistent. If the BIOS upgrade does not correct the process of upgrading or unexpected power failure, will result in the system may not start. so must be clear before the BIOS upgrade BIOS of the model. If you are using the current BIOS upgrade tool BIOS backup, then put the disk in the BIOS before a copy. At the same time to see whether the system BIOS whether to support recovery and also to know how to restore.
8, software upgrades inappropriate: Most people think that software upgrade is not there will be problems. In fact, during the upgrade process will share some of the components of which were also upgraded, but other programs may not support the upgraded components leading to various problems.
9, misuse of test software : the best use of the software test version of the test software is usually a bit BUC or certain not stable enough, after the use of data loss bug, crash or system can not start.
10, illegal uninstall the software: In the uninstall software, do not remove shared files, because some of the shared file system or other programs may be used, once deleted the files, some applications will not start and crashes, or of a system run crash. Do not install the software where directory directly to delete, if directly delete the registry and the Windows directory will have a lot of trash, over time, the system will run the instability caused by crashes.
11, the use of pirated software: check narcotics must be thoroughly tested, because a large some of these software with a large number of viruses, once implemented, will automatically modify your system, infection system or application software, a system crash occurs with heart.
12, application software, shortcomings inherent in the software or system not compatible: This situation is common, such as those running Windows 98 or Windows 3.X in DOS to run a good 16-bit applications. Windows 98 is 32, although it claims is compatible, but in many places is 16-bit applications can not co-ordinated. Microsoft will not make great efforts to research prepared to give up something. So if it is not necessary, it is best not to use 16-bit applications.
13, start the procedure was too more: This makes the system resources exhausted, so that individual program needs of data in memory or virtual memory in Zhaobu Dao, the system will be an unexpected error. Workaround: Do not start too many applications. in case a result, an \error \not familiar with the program.
15, non-normal shut down the computer: Do not directly use the chassis of the power button, otherwise it will create the system file is corrupted or missing, causing auto-start or run in the crash. For Windos 98/2000/NT other systems that this release is very important, otherwise serious, will cause a system crash or hard disk damage serious consequences.
16, sometimes the normal operation of software, but suddenly and inexplicably crash, reboot to run these applications it is very normal, a phenomenon called the phenomenon of suspended animation. there is more than Windows 98 because of memory resource conflict, we all know, software is running in memory, but can be released after the close of space applications. but some applications because design reasons, can not even shut down completely after the release of memory, present a software to use with a memory address, there will be conflict.
In short, Windows is indeed a place of crash of a variety of abnormal shutdown caused The solution must also be targeted, as the computer strange fault, as their solutions are different. said the reason so many computer crashes and ways to let you know, when the computer crashed, the in the end happened What, so do not panic, depending on the situation, take different solutions have only one purpose to make our computers work better.
cheat codes
eliminate blue screen of your computer when this happens, normal operation, suddenly out of a prompt, you performed an illegal operation, the program will be shut down, any questions please contact the vendor. press the \appears \was that it exists, then modify the image of dry, creation of documents, web pages, and so on, anyway you have just received the results of hard work along with it wiped out the. In the absence of practical remedial measures, In addition to nothing with this other than to do nothing.
reason, the system generated GPE and general protection error. In addition to Microsoft’s \There may be some other conflict, your computer’s available resources is also an important factor reduction. In fact, a very simple principle, but many users do not pay attention to, the following came to talk about how to reduce the computer resources and reduce occupancy. We know that the computer resources, including GDI (graphical interface) resources; USER (user) resources; SYSTEM (system) resources of three. where GDI resources are mainly kept the menu button, control panel objects, color palettes, etc. content; USER resources, the main menu of the window, save the information; the SYSTEM save resources, mainly the system resources and common resources, reduce and reduce the footprint of the computer all efforts must focus on these three aspects. to understand the causes of , you can check against the lower back.
a timely manner without the program being shut down some of the procedures in time after the use
can also turn off to save resources. If you want to know the resources of a program then the situation can make use of Windows in the \; Programs \ Accessories \ System Tools \ Resources \situation.
2, set in the same window, navigate to the folder
in Windows 98, the system default setting is already using the same window folder view, generally do not need another set. while in Windows 95 and Windows 97 in , the system default settings instead of using the same …
