The reason of computer blue screen and its solution

"Blue screen fault and other failures, according to the causes can be divided into software and hardware two aspects." Now or follow the first soft after the principle of hard to see the cause of the failure and solutions!

One, the software caused by blue screen failure

1. Blue screen failure due to damage or loss of important files (including virus).

Instance: VxD in Win98 (virtual device driver) or. DLL Dynamic Connection library, such as the loss of important files, the situation is generally more serious, there will be a "blue screen warning."

Workaround One: Note the missing or corrupted file name extract and recover damaged or missing files from the Win98 installation disk using the "EXT" command in the Win98 boot disk as follows:

(1) using the Win98 boot disk to boot the computer, typing "Ext" command at the prompt.

(2) At the prompt "Please enter the path to the Windows CAB files (a):" After entering the full path of the Win98 installation compression package, such as "F Pwin98win98", complete after carriage return.

(3) At the prompt "Please enter" the name (s) of the file (s) for you want to extract: "After entering the missing file name you wrote down, such as" Bios.vxd ", enter.

(4) In the decompression path prompt "Please enter path to extract to" (' Enter ' for the current directory): "The input file will be decompressed to the full path, such as" C Windowssystem "and hit enter.

(5) Finally appear confirmation Prompt "Is this OK?" (y/n): ", enter" Y "after carriage return. The EXT program automatically finds the CAB compression pack in the installation disk and releases the file to the specified location.

(6) Reboot can be.

Solution Two: Antivirus with antivirus software. Some viruses may damage the registry key after antivirus and the registry should restore the backup before poisoning.

Workaround Three: If you can start the graphical interface, you can take a reload motherboard and graphics driver, and the "System file Scan" to restore damaged or missing files. The system file scan method is to click Start/Program/attachment/System Tools/System Information/tools/System File Checker, and then scan the changed files.

2. Registry corruption causes the file to point to a blue screen caused by the error.

Example: Unauthorized alteration of the registry (including manual alteration and automatic replacement at software installation) Occurs when the system is turned on or a blue screen appears when the program is invoked, and the screen has an error message displayed (contains the file name of the error).

Workaround One: Restore the backup.

(1) Click Start/shutdown/Restart your computer and switch to MS-DOS mode, and then click Yes;

(2) Enter the Windows directory. For example, if you have Windows installed in the "C Windows" directory, you should type the following "CD C Windows" and then return;

(3) Type "Scanregrestore" and return.

(4) Following the steps above, you can restore the registry to the state of the last time you started the computer.

Workaround two: Delete the key value.

If there is a blue screen after the uninstall program, the author concludes that the fault is due to the incomplete program uninstall. Solving this kind of problem is very simple, first you have to write down the wrong file name, and then go to the registry to find the following branch "Hkey_local_machinesystem

Currentcontrolsetservicesvxd ". In the "Find" Enter the file name just now, you can delete the key value found. At this point, do not forget to back up the registration form Oh!

Typical case: The author in the removal of Jinshan poison tyrant Midway, the restart after the first saw the desktop icon appears blue screen, and accompanied by error messages appear. The error message mentions that Kavkrnl.vxd file cannot be found, the author first determines that the file is not a Win98 system file based on the first two characters of the filename, and Ka begins with the virtual device driver of Jinshan poison Pa. The basic judgment is that the file points to an error and then decides to delete its corresponding key value in the registry. Type "Kavkrnl.vxd" in the Registry Editor's lookup, and place it in the Hkey_local_

The corresponding primary key value in Machinesystemcurrentcontrolsetservicesvxd "is removed, and the failure is eliminated after reboot."

3.system.ini the "blue screen" caused by a file error.

Instance: the error caused by software Uninstall or the System.ini file not being updated immediately after installation.

Workaround: Disable the entry in the registry or reinstall the appropriate software or driver.

4.win98 's own imperfections cause a blue screen.

Example: Win98 's SP1 and Microsoft's Vxd_fix.exe patches play a crucial role in Win98 stability.

Solution: Download it quickly, such as Huajun website, Nanjing Station, HTTP//nj.onlinedown.net/win98sp1.htm Win98sp1 and HTTP//nj.onlinedown.net/windows98vxdpatch.htm Vxd_fix.exe.

5. System resource depletion caused by blue screen failure.

Example: blue screen failures often occur when you are doing a larger job, or when you save a copy, and often occur more suddenly. This type of failure occurs mainly in relation to the occupancy of three heap resources (system resources, user resources, GDI resources).

Solution: Open your Resource status monitor, look at the remaining resources, if your three resources are at 50% or lower, it is easy to appear such as "illegal Operation", "blue screen" or "Crash" failure. To do this, you must reduce waste of resources, reduce unnecessary program loading, and avoid running large programs (graphics, audio, and video software) at the same time, such as load scheduler, input method and sound indicator, DOS driver for sound card, System Monitor program, and so on.

A blue screen failure caused by a 6.DirectX problem.

Example: (1) DirectX version is too low or too high, (2) The game is incompatible with it or not supported, (3) auxiliary important files are missing, (4) The video card does not support it.

Workaround: Upgrade or Reload DirectX. If the video card does not support the high version of DirectX, it means your video card is too old, try to update the BIOS and driver of the video card, otherwise, you have to pay to upgrade the video card.

Second, the hardware caused by the blue screen failure

1. Memory overclocking or instability caused by the blue screen.

Instance: Random blue screen.

Solution: Use the normal frequency first, if there are any problems. Find a good memory for the failure of the replacement lookup, can generally be resolved. Then you should pay attention to the CPU when the memory is very close to the problem of heat dissipation.

2. Poor compatibility of hardware caused by blue screen.

Compatible machine is good at its high cost-performance, bad on the bad in the assembly, because the user does not have the perfect monitoring means and the corresponding knowledge, can not carry out a series of compatibility testing, so that the hidden danger in the future use of the process.

Instance: When the memory is upgraded, the failure of the different specifications of the memory strips is mixed.

Solution: Note the memory of the manufacturer, memory particles and batch number of differences, often because of the different memory in the main parameters of the difference in the blue screen or panic, or even more serious memory failure. You can also change the slot position in which the memory bar is inserted. If the memory is still not working properly, it has to be replaced. Here, to remind you: memory in the whole computer system plays a very important role, it will directly affect the stability of the system, so in the purchase of memory to pay attention to, it is best to have the company of pedestrians, to avoid buying remark of the sliver or too low frequency of the note.

3. Hardware cooling caused by the "blue screen" fault.

Example: In the computer cooling problem on the fault, often have a certain law, generally in the computer running for a period of time before appearing, performance for the blue screen crash or random restart. The main cause of the failure is the data reading and transmission errors caused by overheating.

Solution: To take overclocking should be reduced frequency, over-temperature should be cooled. In fact, not all of the failures are so complex, sometimes from a simple aspect, but also can be a good solution to the problem to learn analogy.

4.I/O conflict caused by the blue screen phenomenon.

Solution: This phenomenon appears relatively few, if there is, you can remove the system from the device with a! Number or number, restart the computer for confirmation, or please master manually allocate system resources.

All things to nip in the bud, the following is the author summed up some of the experience available for your reference:

1 regularly to the important registry files for manual backup, to avoid system errors, can not be replaced in time to backup files and produce irreparable errors.

2 try to avoid abnormal shutdown, reduce the loss of important files. such as. VxD. DLL files, and so on.

3 for ordinary users, as long as the normal operation, there is no need to upgrade the graphics card, motherboard BIOS and drivers, to avoid the damage caused by upgrades.

4 regularly check the optimization system files, run the System File Checker for file loss checking and version proofing. Check the steps to see the previous instructions.

5 Reduce the installation of unwanted software, try not to manually uninstall or Remove Programs, to reduce the illegal replacement of files and files point to the error of the occurrence.

6 If the memory is not particularly large and its management program is very good, as far as possible to avoid large programs at the same time, if you find that in listening to MP3 when there is Chachalaras sound, the basic can be determined that the fault is caused by insufficient memory of the big intelligence if fish 2008-07-06 10:33 prosecutor

1: Blue screen is the most common memory problem:

First, unplug the memory strips and plug them in with an eraser and a gold finger.

If there's a lot of dust in the chassis and it's been a long time cleaning up, it's better to clean

By the way, remove the memory slots with a brush and hair dryer

2: System hardware conflicts caused by

My Computer--right-click Properties--Hardware--Device Manager--check for a device with a yellow question mark or exclamation point, such as the presence of an attempt to remove it and restart the computer.

3: System problems

To see if the boot boot is loaded too much, if it is, it is best to shut down some unnecessary program startup and service: Start-run-input msconfig--start the program except Ctfmon and antivirus software, all the others are off.

In addition, too much fragmentation of the hard disk, but also easy to lead to the "blue screen" appearance: Open My Computer--c disk Properties--tools--defragmentation to clean up all the dishes

4: Virus Reason

If the computer does not install antivirus software to download the latest version of anti-virus software on the system to antivirus and eliminate malicious software
