Your side of the computer repair experts

1, infected with the virus due to
This is often manifested in the open IE, the IE interface, in the lower left box tips: Opening page, but Lao Bantian did not respond. In view the process in Task Manager, (enter method, the mouse on the taskbar, press Right m m process, the Task Manager) to see how the CPU occupancy rate, if it is 100% sure that is infected with a virus, then you want to run other programs is simply suffer. This is what we should look up the process of greedily taking up CPU resources.
Once found, it is best to record the name, then click the end, if not end, will have to boot into safe mode to remove the stuff, but also access to the registry, the (method: Start m Run, type regedit) in the registration Table dialog box, the point of editing m to find, enter the name of the program, found, right click delete, and then the search several times, often to completely remove the cleaner.
There are many viruses, antivirus software can do nothing, the only way is to manually remove.
2, and set the proxy server the
Some cheese, for some considerations, in the browser set the proxy server (Control Panel – Internet Options LAN set m m m connection using a proxy server for the LAN), set the proxy server is the network does not affect the QQ, because QQ using a 4000 port, and access to the Internet using port 80 or 8080. This is a lot of cheese they can not understand why the QQ, while the reason can not open the page. The proxy server is generally not very stable, and sometimes to the Sometimes not on. If there is such a setting, please cancel the agent on it.
3, DNS server error
explain
The so-called DNS, or domain name server (Domain Name Server), which convert the domain name to identify the IP address of the computer, such as the Shenzhen Window (www.sz.net.cn) the corresponding IP address is 219.133.46.54, Shenzhen Hotline (www . szonline.net) the corresponding IP address is 202.96.154.6. If the DNS server error, then the domain can not be explained naturally can not access the.
If this is the case, sometimes the network service access provider or ISP’s problem, called the Advisory ISP; sometimes the router or network card problem, not with the ISP’s DNS service to connect.
This is the case, can the router off for a while to open, or re-set the router. Or the card can not automatically find DNS the server address, you can try to use the specified DNS server addresses. In the network properties in conduct, (Control Panel m networks and local dialup connection to connect m m right property mTCP / IP protocol m property m using the following DNS server addresses). different ISP have different DNS addresses, such as telecommunications common is 202.96.134.133 (main use) 202.96. 128.68 (reserve).
Updated network card drivers or replace the card would be a thought.
Fourth, the system file is missing cause IE not start
This phenomenon is quite common, as:
1, the system’s instability manifested as frequent crashes, often getting reset, illegal shutdown causes the system file is missing;
2, software and hardware conflicts Changbiaoxianwei caused some programs installed network card driver conflict or conflict with IE. Since the introduction of Hyper-Threading CPU INTEL after, there is a prominent problem is that IE6 under XP SP1 and Hyper-Threading conflict;
3, virus, intrusion led to system files corrupted or missing.
If this is the first case, try repairing the system, 2K or XP system, put the original installation CD-ROM (Note: must be the original installation CD), running in at the beginning of m input sfc / scanow, press the Enter .98 in the system sfc command can also be checked.
If this is the second case, can be newly installed hardware or programs to uninstall, 2K or XP system can start after the machine, press F8, enter the Start menu, select \You can also use the system restore function, general can solve the problem quickly.
If it is XP system because of the reasons for hyper-threading CPU, Hyper-Threading disabled in BIOS, or upgrade to SP2. (Of course, XP SP2 to upgrade involves a lot of knowledge and pay attention to the problem, not go into details in this limited space ). this case, QQ TT comes with the browser in general to the normal view, can use a try.
If this is the third case, they have on the system tray full of killing the virus.
There is also a phenomenon also need to pay particular attention to: that is to open the site’s home page, but you can not open the two links, if so, the processing method is to re-register the following DLL files:
M run at the beginning to input:
regsvr32 Shdocvw.dll
regsvr32 Shell32.dll (Note that this command, first do not lose)
regsvr32 Oleaut32.dll
regsvr32 Actxprxy.dll
regsvr32 Mshtml.dll
regsvr32 Urlmon.dll
regsvr32 Msjava.dll
regsvr32 Browseui.dll
Note: Each input 1, press Enter. The second command can first do not lose, after the completion of these commands to restart windows, if found to be invalid, and then re-enter again, this time enter the second command. Also, if 98 systems to Microsoft’s Web site to download this file may be simpler, the file download address is:
http://download.microsoft.com/download/msn…us/mcrepair.exe
5, IE damage
If these methods do not work, it may be IE’s core damage, despite the system repair, can not make up, then reinstall IE is the best way for.
If you are 98 or 2K system, IE version if 5.0 is recommended to upgrade to 6.0.
98 of the system if you have installed the 6.0 upgrade, then the control panel, click Add / Remove Programs dialog box will pop up a repair, choose the default repair, re-start can be.
If 2K + IE6.0 or XP (comes with IE is 6.0) of the system, re-IE a little trouble, there are two ways:
1, open the registry, expand HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Active Setup \ Installed Components \ (89820200-ECBD-11cf-8B85-00AA005B4383), the IsInstalled DWORD value of 0 can be changed;
Note: reinstall IE does not necessarily solve the problem, only the idea of a deal with the problem only.
Recently found that many users can not browse the web like asking the question, really too many people asked, to address Members of the doubt, I have collected some information and you explore and how to exclude this fault. (Dao Beicha first) but of course even and we analyze the more common with the failure of a concrete analysis of specific need, you can refer to several situations to do the appropriate measures to bring hope to give you help. If you feel good, remember to help even the top look, do not let This post sunk, so that more people can see.
Case 1: the Internet can not browse the web but can use QQ to chat.
1, the browser \Solution: Set the correct access type. If the Internet through a proxy service, please fill in the correct proxy server IP address and port number; If not, please do not check the \2, DNS server settings wrong
Solution: If the ISP provider is assigned to your fixed IP address, then please fill in the correct IP address and ISP provided DNS server addresses; if the ISP provider is a dynamic allocation of IP addresses, so no need to fill in DNS server addresses; Another may be the ISP provider’s DNS server error can not correctly convert between domain rIP address, this time you can in your browser’s address bar, typing the site IP address, you can visit the website.
3, the firewall settings error
Solution: If the firewall settings properly, there may be barriers to exchange information with external networks, resulting in the failure can not browse the web. We can modify the firewall settings. What, how changes? This is not I say it. Ah, or say a few words, friends do not understand the direct election for the default level, select \Case 2: ADSL successful landing but could not visit the website of the fault solution
Should first PING ISP’s DNS server addresses, to see if PING pass, if PING pass, most of the software problems are the majority, if not PING pass, you should check the hardware device / line connection status and communication protocols (TCP / IP) < br />
If PING pass, you can see information similar to the following:
Command ING 202.98.160.68
Reply from 202.98.160.68: bytes = 32 time = 14ms TTL = 250
Reply from 202.98.160.68: bytes = 32 time = 27ms TTL = 250

Reply from 202.98.160.68: bytes = 32 time = 17ms TTL = 250
If you can not PING pass, have the following information:
Pinging 202.98.160.68 with 32 bytes of data:

1. More computer friends, you can replace with another computer, replace the computer not to install any proxy server software, do not install any firewall, and only one network card installed and ADSLMODEM directly connected to ADSL dial the correct software installed. to see whether the normal view, if fault is caused by the client computer, if not, would need to detect whether the MODEM and the line normal.
2. Only one computer in a friend, you can stop the run all the proxy server software, such as WINGATE, SYGATE, WINDOWS’s INTERNET Connection Sharing (ICS), etc., can exclude a direct login to see trouble, you stop running proxy server software troubleshooting, it is certain that proxy service software problems.
3. Check your browser settings for IE in particular, for example, the most common cause of failure can not browse the web in IE, select the \Click Tools – \4. Check TCP / IP protocol of the property, in particular, DNS server settings are correct, Kunming, ADSL users can set the master DNS server: 202.98.160.68, secondary DNS can be set to: 202.98.161.68, particular note yes, dial-up software is different from the location of DNS settings are not the same, and some (in the dial-up network connection icon in the properties settings, some network settings in the Control Panel, some of the dial-up software (such as ENTERNET300) own property in connection Profile set. This 3 place to be sure to set the correct.
5. With WINDOWS friend, if after the tests have confirmed that is correct, be ready ADSL dial-up software and WINDOWS system disc, then remove the dial-up software first, then remove the Control Panel / Network and all of the TCP / IP protocol, restart the computer and re-add the TCP / IP protocol, and open the MODEM power, reinstall the dial-up software, tested, if the settings are correct, reinstall dial-up software and TCP / IP dial-up can be resolved after the most dialed the problem but can not browse the web. < br />
6. Replacement of a browser such as Netscape NETSCAPE browser test.
7. If you are directly connected to ADSL MODEM Internet access that computer, two network cards installed, try to connect local area network card first picked up, leaving only the ADSL MODEM to connect the network card. And then to see whether the fault exclusion, if troubleshooting , you should check the network and system resources. In particular, look at cards and other devices have no conflict (WINDOWS users in the Control Panel / System / Device Manager to view the equipment is normal)
8. Your network card to enable the BOOT ROM boot chip functionality, and network card with PXE boot after chip caused. Can be resolved:
① If the card is integrated on the motherboard, or the online activation process written into the BIOS, you can modify the system settings from the BIOS boot sequence, such as setting the first boot hard drive, or from prohibiting card BIOS boot the system. < br />
② If the card is not integrated, you can unplug the network card on boot or with a card chip to set procedures, prohibition of the network card BootROM guiding function can also be shut down, and then later in the boot, when there is \Press \Case 3: Sharing the Internet can not browse the Web
Machine with Windows XP, do the LAN proxy server and found the other computer can not browse the Web, but there is data flow, you can also use QQ, software, network, each machine can also be exchange of visits. Proxy server for dual network card, network Configuration wizard is set to \b NIC). client set to \and Broadband Modem connection), but the client only occasional bright light on what. In the opening pages, you can see in the status bar \Last Show \Solution: It may be your cable connection and DNS settings problems:
① to do a cascade line, will be a network card to connect directly to broadband ADSL, the other fixed.
② Set the IP address of other clients as 192.168.0.2,192.168.0.3,192.168.0.4 hh, subnet mask set to 255.255.255.0, set the gateway address for each client is 192.168.0.1, set the DNS for your The ISP’s DNS addresses.
At the same time, you can also consider a proxy server, if there is conflict between the NIC, A change of PCI slots, and other peripherals do not need to remove a temporary solution to the problem also has some help.
Common ADSL
of Flow
Page does not open, download interruptions, or online video and audio stream interruption, these are a lot of people will use ADSL Internet trouble. But when carefully examined the status of ADSL MODEM, the will dial-up login has been successfully found. So, what went wrong?
1. Line instability
If the home too far from the bureau (5 km) can be reported to the telecommunications sector. To ensure that the correct connections (voice separator different connection method is different, make sure the correct guidelines in accordance with the instructions to connect). While ensuring good quality line communications there is no interference, no lines to connect other cause interference devices, such as telephone extensions, fax machines, etc.. and check the junction box and crystal head and whether there poor contact with other wires around with string. conditional best to use a standard telephone line, if it is meet the International Telecommunication Union ITU standard three, five or more over five twisted pair. telephone lines after a separate walk-home. line go phone line to go the computer. If you want to install the living room ext, the best quality and good selection of junction box. PC access ADSL Modem with a twisted pair. (Note: The phone must not be placed next to the ADSL Modem, every few minutes because the phone will automatically search the network, then strong The electromagnetic interference is sufficient to cause ADSL Modem stop.)
2. Check your network card, if it is better to replace PCI ISA network card, and choose good quality card, the card may be too low causing the problem or 10M/100M culprit .10 M card can be adaptive. Other , the same two-card lead to conflict, concern, then, should be uprooted to connect local area network or other computer network cards, network cards only ADSL internet connection test, if the failure to restore the normal, check the two network cards have no conflict.
3.ADSL Modem or network card settings are incorrect
The most common mistake is to set the IP address of ADSL Modem, or an error set the DNS server. Because of the virtual dial-up for ADSL users who do not need to set the IP address is automatically assigned you can .TCP / IP Gateway generally do not need to set. Also, if DNS settings must be set correctly, if the operating system is Windows 9x, type in the DOS window Winipcfg obtain DNS address, in Windows 2000/XP, type ipconfig / renew, or ask the local telecommunications sector.
In addition, TCP / IP settings most likely to cause the situation can not browse the web, for example, has not changed settings, has been to the normal view, suddenly found here is not normal, you can try to remove TCP / IP protocol re-add the TCP / IP protocol.
4.ADSL Modem Synchronization exception
Check your phone line and ADSL connection is poor contact areas, or a phone line problem. If you suspect a bad splitter or ADSL Modem bad, try not to use separator directly to an outside line access ADSL Modem. If you determine separator is no problem, to ensure that splitter and ADSL Modem connection should not be too long, too long, then synchronization is difficult. If the exclusion of the above, as long as the weight from the ADSL Modem can solve the synchronization problem.
5.
Dial-up software mutual interference
ADSL Internet access the way the virtual dial-up and dedicated access to two types of ADSL users are mostly individuals with the former. And PPPOE (Point-to-Point Protocol over Ethernet Point to Point Protocol over Ethernet) virtual dial-up software have their own advantages and disadvantages. After many tests on different operating systems, if you use the operating system is Windows XP, recommended PPPOE dial-up software comes with it, less of Flow stability is also enhanced. If you are using Windows ME or 9x, can be several virtual dial-up software mmEnterNet, WinPoET, RasPPPoE. which, EnterNet is a commonly used now, EnterNet 300 applies to Windows 9x; EnterNet 500 apply to Windows 2000/XP. When you use a PPPOE dial-up software has a problem, may wish to uninstall the software for others to use a PPPOE dial-up software, make sure to be careful not to put in multiple PPPOE software to avoid conflicts.
6.
Other software conflicts
Uninstall the software could lead to drying up, and now find that some software such as QQ 2000b, etc., occasionally causing the Internet drying up, and under what conditions trigger specific, yet to be further tested. Many users find that after unloading stop solved the problem , including the use of ordinary Modem 163 dial-up users of this method is also useful to solve the drying problem situation, I also received e-mail a friend stop to reflect upon unloading QQ solve the problem, so if you have QQ, you may wish to uninstall OICQ , and then try the Internet. When you open some of the software have found that the phenomenon of drying up, shut down the software on all normal, try to uninstall the software.
7. Virus attacks and firewall software settings properly
Although attacks by hackers and viruses are less likely, but do not rule out the possibility. Virus associated components, if damaged ADSL will stop the phenomenon to occur. Recommended that you install the \\phenomenon should check the installation of a firewall, Internet sharing proxy server software, Internet software, speed up, stop running such software, then online test to see whether the rate of return to normal.
To sum up the time, the Internet can not browse the Web is one of the most common faults, the specific number of complicated factors, the solution is different. We can be: soft and then hard after the first system, the first after the complicated simple, binary search reduce the fault coverage. concrete has the following main steps:
The first step: exclude accidental, unforeseen failure
Just-do, the first cold start the computer and modem, rule out the possibility of occasional, unforeseen failure, such as software conflicts, memory disorder, ADSL Modem automatic disconnection, IP adjust the automatic disconnection, equipment, sleep, etc. problem. still OK and then asked each other or other normal computer can browse the Web, judgments are common problems or personality problems. If the problem is common on the Internet can only be resolved by the ISP, will have to check the server on the LAN or network line. If personality problems, it can focus attention to the network and the machine up.
Step two: identify the problem areas preliminary
Check with the command ping judge. Main ping the following address: One ping the machine loop address (127.0.0.1), if the show Reply from 127.0.0.1: bytes =?? Time =? Ms TTL =???, said TCP / IP protocol to run properly, if the show Request timed out (timeout), you must reinstall the agreement. Second, ping the local IP address. using the ipconfig command (9x system should enter winipcfg) view of the machine IP address, that if the General Network adapter is working properly, or may be network card, Modem problems. Third, ping the computer with the segment address. If the network links that the paragraph in question. If the networks have gateways, routers, will have to ping each paragraph with Ben Wang and other segments of the IP address connected to the port to determine whether failure. Fourth, ping the primary, alternate DNS server and Web server address, if General contact address with the network or ISP.
If the address can ping through, you can determine the operating system and browser’s fault. If the interruption occurs during time-out error (to take into account server may set the case against ping), show that the network unstable, packet loss, For example, a LAN broadcast storm may produce intermittent, it is usually the network connection, configuration errors, or user to its excessive.
The third step: rule out the possibility of \First check the network configuration. Check TCP / IP protocol setting case, network card, Modem and other equipment of the parameter settings, focusing on IP address, gateway, DNS address is correct, if wrong then return to normal settings. Inspection Agreement , the network adapter is excessive, proposed to delete the \. Check whether the error set up dial-up adapter IP address, because the upper hand in the traditional dial-up IP address is assigned automatically, configure the network card in the computer when it is possible to set the network card on the fixed IP address set in the dial-up adapter error , will lead to dial-up Internet access. check whether the dial-up ISP requirements related settings, such as dial-up numbers in some areas, the user name and password to adjust, and to 16300,16900 so.
Second, check card, Modem device driver is such a problem, if detected in the Device Manager have yellow! Or?, To re-install the matching driver.
Third, check whether the system is infected with a virus. Antivirus software will upgrade to the latest version of comprehensive anti-virus.
Step four: rule out the possibility of \First check the network card, modem, etc. all are working properly (it is disabled). Check overheat job instability, such as light through Modem, LAN indicator is working correctly observed (control instructions, etc. observation). with the replacement method (for this device to another device or computer test) to check whether the network card, Modem poor quality or compatibility.
Second is to check whether the network interface failure. Check the board (such as network card) is disabled. Board, line, RJ-11 and RJ-45 cable connector plug for many, too much dust, aging may lead to false then , loose, power could be shut down after the cotton removed with an eraser or alcohol test, re-plug, or another slot, interface, try, or re-connection lines and isolation with insulating tape reinforced or replaced. RJ-45 interface, for example, often to loosen the situation, can Crimping Pliers reinforcement.
Third, check whether there is smooth outside. If the phone line, check whether the normal telephone line can be on the phone into Modem cable to listen to whether the dial tone telephone, or direct dial-up test. From the ISP to the ADSL filter this connect any device to join will be harmful to the normal transmission of data, so before the filter and do not answer the phone, a device such as phone theft fighting. If the old-fashioned Modem Internet access, telephone features can not open the security fight. Check ADSL Modem points frequency is connected correctly, that phone into the wireless access divider Line mouth, telephone or fax machine connected Phone mouth, broadband access ADSL modem telephone line port.
Fourth, check the voltage is stable, the ambient temperature is too high (low) and the network line is busy.
Step Five: troubleshoot your browser,
Repair your browser. The browser settings back to the default values of all and try and remove set elements. Fix the browser can use the \Try to install other browsers.
Sixth step: Eliminate operating system failure
First fix registry. As to visit a malicious website may lead to the computer registry to be changed, not the Internet. Through the registry repair devices, Internet assistants and other tools or scanreg / restore command to repair the registry.
Second, turn off the other part is already running may cause conflicts in the memory-resident program (or process), close or disable other devices (such as other network card, Modem, shared resources related equipment, etc.), and then try whether the Internet. < br />
Third, check the operating system file is damaged. With a Windows System File Checker checks (win98′s use sfc, win2000 and above with sfc / scannow), if the destruction was prompted to restore.
Fourth, reinstall the operating system. From the perspective of data protection, it is recommended covering the installation, if not yet ready to solve the problem in the driver installation disk, a backup of important data backed up (preferably first system partition Ghost), under the premise of , format install the operating system.
Do not mind a small sum up it again, DNS server settings wrong, TCP / IP protocol error, this is the most common error. You need to first check the dial-up network, the master DNS and secondary DNS for errors, attention here is to check \Dial-up Network \a phone call on it. What, you do not know what they call? I do not know, I have a problem regardless of the village, playing 110 on it, or free of charge. you can try it. do not ask how to set up DNS I had it, trouble will not be a friend tell a friend, I on behalf of the party and the state had to salute you.
Let me say the following as TCP / IP protocol problems caused by the fault, if you checked these settings and found no error set, but still can not browse the web, then you should check the \Double-click \The following network components are installed \t dial-up network adapter
tTCP / IP
Here special attention to two points: First, if repeated here to install two network adapter or dial-up TCP / IP, the result can not browse the Web, how to see a repetition of it installed? If the repeat dial-up network adapter installed, You will see a line that says \If you find such a line # 2, please works …
