1. Blue screen failure caused by software
1. Blue screen failure caused by damage or loss of important files (including virus).
example: VxD (virtual device driver) or. ．DLL in Win98? When important files such as dynamic link library are lost, the situation will generally be more serious, and a "blue screen warning" will appear.
Solution 1: Write down the missing 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) Boot the computer with the Win98 startup disk and type the "ext" command at the prompt.
(2) after the prompt "please enter the path to the windows cab files (a):", enter the full 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 (s) of the file (s) you want to extract:", enter the lost file name you wrote down, such as "Bios．Vxd" and press enter.
(4) enter the full path to which the file will be extracted after the prompt "please enter path to extract to ('enter' for current directory)", such as "c? \ ＼Windows＼System "and press Enter.
(5) at last, 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: kill virus with anti-virus software. Some viruses may destroy 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 "system file scanning" to recover the damaged or lost files. What is the method of "system file scanning"? Click Start/Programs/Accessories/System Tools/System Information/Tools/System File Checker, and then scan the changed files.
2. Blue screen caused by file pointing error due to registry corruption.
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 turned on or called, and an error message is displayed on the screen (including the wrong file name).
solution 1: restore the backup.
(1) Click "Start/Shutdown/Restart Computer and 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 the blue screen appears after uninstalling the program, the author concludes that the fault is caused by the imperfect uninstallation of the program. Solving this kind of problem is very simple. First, you should write down the wrong file name, and then find the following branch "HKEY _ local _ machine \ system
\ current control set \ services \ vxd" in the registry. Enter the file name just now in "Search" and delete the found key value. At this point, don't forget to back up the registry!
typical case: the author crashed in the middle of deleting Kingsoft Internet Security, and a blue screen appeared as soon as I saw the icon on the desktop after restarting, accompanied by an error message. It is mentioned in the error message that the file kavkrnl．vxd cannot be found. The author first determines that the file is not a system file of Win98 according to the first two characters of the file name, 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 the registry editor, delete its corresponding primary key value in "HKEY _ local _
machine \ system \ current controlset \ services \ vxd", and eliminate the fault after restarting.
a "blue screen" caused by an error in the p>3．System．ini file.
example: an error caused by software uninstallation or failure to update the System．ini file immediately after installation.
solution: disable this item in the registry or reinstall the corresponding software or driver.
4. the blue screen caused by the imperfection of win98 itself.
example: sp1 of Win98 and Vxd＿fix．exe patch of Microsoft play an important role in the stability of Win98.
solution: go and download it, such as Nanjing Station of Huajun website/win98sp1.htm? Win98sp1 and/windows 98 vxdpatch.htm? Vxd＿fix．exe 。
5. blue screen failure caused by system resource exhaustion.
Example: Blue screen failure often occurs when a big job is being done, or when a copy is being saved, and it often happens suddenly. The cause of this kind of fault is mainly related to the occupation of three heap resources (system resources, user resources and GDI resources).
Solution: Open your resource status monitor and look at the remaining resources. If your three resources are all at 5% or even lower, it is easy to have failures such as "illegal operation", "blue screen" or "crash". Therefore, we must reduce the waste of resources, reduce unnecessary program loading, and avoid running large 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 monitor programs, and so on.
6. blue screen failure caused by DirectX problem.
example: (1)DirectX version is too low or too high; (2) The game is not compatible with it or not supported; (3) Loss of auxiliary important documents; (4) The graphics card does not support it.
solution: upgrade or reinstall DirectX. If the graphics card does not support the higher version of DirectX, it means that your graphics card is really too old. Try to update the BIOS and drivers of the graphics card, otherwise, you will have to spend money to upgrade the graphics card.
2. 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 we should 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 good thing about the compatibility machine is its high cost performance. The bad thing is that when it is assembled, users can't carry out 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 the 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 differences in main parameters of each memory chip that blue screens or crashes, or even more serious memory failures occur. You can also change the slot position where the memory module is inserted. If the memory module still doesn't work properly, it will have to be replaced. Here, I would like to 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, attention should be paid to the purchase of memory, and it is best to have an insider to accompany you to avoid buying Remark-passed notes or notes with low frequency.
3. "blue screen" failure caused by hardware heat dissipation.
Example: The failures that occur in the heat dissipation of the microcomputer often have certain rules, and generally appear after the microcomputer has been running for a period of time, showing blue screen of death or random restart. The main cause of the failure is data reading and transmission errors caused by overheating.
solution: if the frequency is over-frequency, it should be reduced, and if it is over-temperature, it should be cooled. In fact, not all faults are so complicated. Sometimes, considering from simple aspects, problems can be solved well? You should learn to draw lessons by analogy.
4. Blue screen phenomenon caused by I/O conflict.
solution: this phenomenon rarely occurs. if it does, you can delete the tape from the system! Number or? No. of the device name, restart the computer to confirm, or ask the master to manually allocate system resources.
Everything should be prevented before it happens. The following are some experiences summarized by the author for your reference:
1 Make manual backups of 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. Such as. vxd.dll file.
3 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.
4 regularly check and optimize the system files, and run the System File Checker to check the file loss and proofread the version. See the previous related introduction for the inspection steps.
5 reduce the installation of useless software, and try not to manually uninstall or delete programs, so as to reduce the occurrence of illegal file replacement and file pointing errors.
6 If the memory is not particularly large and its management program is excellent, try to avoid running large programs at the same time. If you find a rustling sound while listening to MP3, you can basically judge that the fault is caused by insufficient memory.
