First, the blue screen failure caused by software
1. Blue screen failure caused by damage or loss of important files (including viruses).
For example: VxD (Virtual Device Driver) or. . DLL in Win98? When important files such as dynamic link libraries are lost, the situation will generally be more serious and a "blue screen warning" will appear.
Solution 1: Write down the lost or damaged file name? Use the "Ext" command in the Win98 startup disk to extract and recover the damaged or lost files from the Win98 installation disk. The steps are as follows:
(1) Start the computer with the Win98 startup disk, and type the "Ext" command at the prompt.
(2) After the prompt "Please enter the path of Windows Cab file (a):", enter the complete path where the Win98 installation package is located, such as "f? \ p win 98 \ win 98 ",and then press enter.
(3) After the prompt "Please enter the name of the file you want to decompress:", enter the name of the missing file you wrote down, such as "Bios". Vxd "and press Enter.
(4) After the unzipping path prompts "Please Enter the path to unzip ('enter' indicates the current directory:)", enter the complete path to which the file will be unzipped, such as "C? \ \Windows\System "and press Enter.
(5) Finally, a confirmation prompt "Is this ok? (y/n): ",enter" y "and press Enter. The "Ext" program will automatically find the CAB compressed package in the installation disk and release the file to the specified location.
(6) Just restart.
Solution 2: Use antivirus software to kill viruses. Some viruses may damage registry keys? After antivirus, the registry should restore the backup before poisoning.
Solution 3: If you can start the graphical interface, you can reinstall the drivers of the motherboard and graphics card, and perform a "system file scan" to recover the damaged or lost files. What is the method of "system document scanning"? Click Start/Programs/Accessories/System Tools/System Information/Tools/System File Checker, and then scan the changed files.
2. The registry is damaged, which leads to file pointing error and blue screen.
For example: unauthorized changes to the registry (including artificial changes and automatic replacement during software installation)? The phenomenon is that a blue screen appears when the program is opened or called, and an error message (including a file name error) is displayed on the screen.
Solution 1: Restore the backup.
(1) Click Start/Shutdown/Restart the computer to switch to MS-DOS mode, and then click Yes;
(2) Enter the Windows directory. For example, if your Windows is installed in "C? \ \Windows "directory, you should type the following? “CD C？ \ \WINDOWS "and press Enter;
(3) Type "SCANREG\RESTORE" and press Enter.
(4) According to the above steps, the registry can be restored to the state when the computer was last started.
Solution 2: Delete the key value.
If a blue screen appears after uninstalling the program, the author concludes that the fault is caused by imperfect uninstallation of the program. Solving this kind of problem is simple. First, you should write down the wrong file name, and then go to the registry to find the following branch "HKEY _ Local _ Machine \ System".
\ Current Control Set \ Service \VxD. Enter the file name in "Search" and delete the found key value. At this point, don't forget to back up the registry!
Typical case: the author crashes in the middle of deleting Kingsoft Internet Security, and a blue screen appears as soon as he sees the icon on the desktop after restarting, accompanied by an error message. The error message mentions that the file kavkrnl.vxd cannot be found. According to the first two characters of the file name, the author first determines that the file is not a system file of Win98, and the virtual device driver of Kingsoft Internet Security should start with Ka. Basically, it is judged that the file points to an error, so it is decided to delete its corresponding key value in the registry. Enter "Kavkrnl.vxd" in the search of Registry Editor, and put "HKEY _ local _ _
The corresponding primary key value in machine \ system \ currentcontrolset \ services \ vxd "was deleted, and the fault was eliminated after restarting.
3.3. The resulting "blue screen". Error in System.ini file.
Example: An error caused by the failure to update the System.ini file immediately after the software is uninstalled or installed.
Solution: Disable this item in the registry, or reinstall the corresponding software or driver.
The blue screen caused by the imperfection of 4.4. Win98 itself.
Example: sp 1 of Win98 and Vxd_fix.exe patch of Microsoft play an important role in the stability of Win98.
Solution: Go and download it, for example, Nanjing Station of Huajun.com /win /Win98SP 1.htm? Win98sp 1 and /windows98vxdpatch.htm? Vxd_fix.exe .
5. The exhaustion of system resources leads to blue screen failure.
Example: Blue screen failure often happens when doing big homework or saving and copying, and it often happens suddenly. The reason for this failure is mainly related to the occupation of three piles of resources (system resources, user resources and GDI resources).
Solution: Open the resource status monitor to see the remaining resources. If your three resources are all at 50% or even lower, it is easy to have failures such as "illegal operation", "blue screen" and "crash". Therefore, we must reduce the waste of resources, reduce unnecessary program loading, and avoid running large-scale programs (graphics, sound and video software) at the same time, such as loading task planning programs, input methods and sound indicators, DOS drivers for sound cards, system monitoring programs, and so on.
Blue screen failure caused by 6.6. DirectX problem.
For example: (1)DirectX version is too low or too high; (2) The game is incompatible or unsupported; (3) Loss of important auxiliary documents; (4) The graphics card is not supported.
Solution: Upgrade or reinstall DirectX. If the graphics card doesn't support a higher version of DirectX, your graphics card is really too old. Try to update the BIOS and drivers of the graphics card, or you will have to spend money to upgrade the graphics card.
Second, the blue screen failure caused by hardware
1. Blue screen caused by memory overclocking or instability.
Example: random blue screen.
Solution: Run at normal frequency first, if there is any problem. Finding a good memory stick to replace the fault can generally be solved. Then pay attention to the heat dissipation of the memory when the CPU is close to the memory.
2. Blue screen caused by poor hardware compatibility.
The advantage of compatibility machine is high cost performance, but the disadvantage is that when assembling, users can't conduct a series of compatibility tests because they don't have perfect monitoring means and corresponding knowledge, thus leaving hidden dangers in the future use process.
Example: When upgrading memory, the failure caused by mixing different specifications of memory chips.
Solution: Pay attention to the differences of manufacturers, memory granules and batch numbers of memory chips. It is often because of the difference of main parameters of each memory stick that it leads to blue screen or crash, or even more serious memory failure. You can also change the slot where the memory module is inserted. If the memory module still doesn't work properly, it must be replaced. Let me remind you that memory plays a very important role in the whole microcomputer system, and its quality will directly affect the stability of the system. Therefore, it is necessary to pay attention to the purchase of memory, and it is best to be accompanied by an insider to avoid buying notes transmitted by notes or notes with low frequency.
3. The "blue screen" failure caused by hardware cooling.
For example, the failure of microcomputer in heat dissipation often has a certain rule, which usually appears after the microcomputer has been running for a period of time, showing a blue screen or random restart. The main cause of the failure is data reading and transmission errors caused by overheating.
Solution: Overfrequency will be reduced, and overtemperature will be cooled. Actually, not all faults are so complicated. Sometimes the problem can be solved well from a simple point of view? You should learn to draw inferences from others.
4. Blue screen phenomenon caused by I/O conflict.
Solution: This phenomenon rarely occurs. If so, you can delete the tape from the system! Number or? The number of the device name, restart the computer for confirmation, or ask the host to allocate system resources manually.
Everything should be nip in the bud. The following are some experiences summarized by the author for your reference:
1 Manually back up important registry files on a regular basis to avoid irreparable errors caused by failure to replace them with backup files in time after system errors.
2 Try to avoid abnormal shutdown and reduce the loss of important files. For example. Vxd.dll files.
For ordinary users, as long as they can run normally, there is no need to upgrade the BIOS and drivers of the graphics card and motherboard to avoid the harm caused by the upgrade.
Check the optimized system files regularly, run the system file checker to check the file loss and proofread the version. See the relevant introduction above for the inspection steps.
5 reduce the installation of useless software, try not to manually uninstall or delete programs, and reduce the occurrence of illegal replacement of files and file pointing errors.
6 If the memory is not particularly large, its management program is also excellent, try to avoid running large programs at the same time. If there is a rustle when listening to MP3, you can basically judge that the fault is caused by insufficient memory.
