Only in the process of playing Daqing mahjong, the computer crashed. Why?

There are many reasons why the computer crashes for no reason. ...

Simple edition

First, the cause of the virus.

Second, the hardware problem. Such as power supply

Third, the problem of software. Such as CPU temperature monitoring software.

Four, the system file is lost, caused by misoperation.

5. Hackers attack you.

The specific solution is to redo the system. 1, 3, 4 and 5 can be excluded. If it is still dead, it is a hardware problem.

Professional edition

Hardware reason: ※:

★ "Poor heat dissipation": The monitor, power supply and CPU will generate a lot of heat in the working process, so good ventilation is very important. If the monitor is overheated, it will lead to color and image distortion and shorten the life of the monitor. Working too long will also lead to poor heat dissipation of power supply or monitor, leading to computer crash. The heat dissipation of CPU is an important issue related to the stability of computer operation, and it is also the "hardest hit" where heat dissipation failures occur.

★ "Dust Black Boy": Too much dust in the machine can also cause a crash. If the floppy disk drive head or the laser head of the CD-ROM drive is contaminated with too much dust, it will lead to reading and writing errors, which will seriously cause the computer to crash.

★ "Software and hardware incompatibility": For example, 3D production and some special software may not be installed or started normally on some computers, and there may be problems with software and hardware compatibility.

★ "Memory decline": mainly caused by loose memory and self-quality. The corner fault of memory stick should be eliminated according to the specific situation. If there is a problem with the quality of the memory, the memory needs to be replaced to solve the problem.

★ "Hard disk failure": mainly bad tracks and bad sectors caused by hard disk aging or improper use. This makes it easy for the machine to collide when moving. Special tools and software can be used for troubleshooting. If the damage is serious, only the hard disk can be replaced. In addition, for motherboards that do not support UDMA66/ 100, we should pay attention to the setting of hard disk operation mode in CMOS.

★ "CPU overclocking": overclocking improves the working frequency of CPU, and may also make its performance unstable. The solution, of course, is also relatively simple, that is, let the CPU return to normal frequency.

★ "Hardware resource conflict": It is common that the settings of sound card or video card conflict, resulting in abnormal errors. In addition, if other devices interrupt, DMA or port conflict, a few drivers may be abnormal, leading to crash. The solution is to start in "Safe Mode" and in "Control Panel"->; "system"->; Make appropriate adjustments in "Equipment Management".

"Inferior accessories": A few unscrupulous businessmen use inferior boards and memory when assembling machines for customers, and some even sell fake motherboards and polished CPU and memory chips. Such a machine is very unstable and will inevitably crash. Therefore, users should be vigilant when purchasing machines.

Software reason: ※:

★ Virus infection: The virus will drastically reduce the working efficiency of the computer, leading to frequent crashes. This kind of fault can be detected by running antivirus software, which should be upgraded in time.

★CMOS settings are incorrect ★ The computer cannot be started due to improper hard disk parameter setting, mode setting and memory parameter setting.

★ System files are deleted by mistake: Command.com, Io.sys, Msdos.sys and other files are needed to start Windows9X. If these files are damaged or deleted by mistake, even if all the hardware settings in CMOS are correct, it will not help. At this time, you need to restart the system with the system disk, and then transfer the system files again.

★ Initialization file is damaged: Because Windows9X needs to read System.ini, Win.ini and registry files, if there are Config.sys and Autoexec.bat files, they will also be read. As long as these files have error information, they may crash, especially the four files of System.ini, Win.ini, User.dat and System.dat are particularly important.

★ Loss of DLL file: There is another kind of file that is also very important in Windows operating system, that is, DLL file with extension, which is an exclusive file in essence. If you delete an application with * * * files, especially important core link files, the system will crash or even crash.

★ Too little spare space or too many fragments on the hard disk: Because some applications need a lot of memory to run, they need to use disk space to provide virtual memory. If the remaining space of the hard disk is too small to meet the needs of software operation, it is easy to cause a crash. The solution to this problem is to divide the disk space reasonably, use the "Disk Defragmenter" to organize the hard disk regularly, and remove the junk files from the hard disk.

★ Improper software upgrade: During the software upgrade, some components enjoyed by * * * will be upgraded, but other programs may not support the upgraded components, resulting in various problems.

★ Abuse of beta software: beta software usually has some bugs or is not stable enough in some aspects. After use, there will be a program error prompt of data loss, crash or system failure to start.

★ Illegal uninstallation of software: If the software installation directory is directly deleted without uninstalling the software, the corresponding linked files in the registry and Windows directory will not be cleared, resulting in system instability and crash. It is recommended to use the uninstaller provided by the software when deleting unnecessary application software. It is best to run the Add/Remove program in the control panel to completely delete the software from the system.

★ Use pirated software: pirated software may contain viruses, which will automatically modify the system once it is executed, causing the system to crash during operation.

★ Too many startup programs: due to too many running programs and the shortage of system resources, the data needed by individual programs cannot be found in memory or virtual memory, and abnormal errors may occur.

★ Illegal operation: Opening or releasing related programs with illegal formats or parameters will also cause the computer to crash.

★ Abnormal shutdown: Don't directly use the power button of the chassis to forcibly shut down, which may easily cause damage or loss of system files and lead to automatic startup or crash during operation. For Windows98/2000/NT and other systems, this is very important, and if it is serious, it will lead to system crash. ★ Memory conflict: Sometimes all kinds of software run normally, but suddenly it crashes inexplicably. It is very normal to run these applications after restarting. This is a false collapse phenomenon. Most of the reason is the memory resource conflict of Win98.

Hardware crashed.

Heat dissipation difference

Monitor, power supply and CPU will generate a lot of heat in their work, so it is very important to keep good ventilation. If the monitor is overheated, it will lead to color and image distortion and even shorten the life of the monitor. Working too long will also lead to poor heat dissipation of the power supply, causing the computer to crash. The heat dissipation of CPU is an important issue related to the stability of computer operation, and it is also the "hardest hit" where heat dissipation failures occur.

Inappropriate exercise

If the computer is greatly shaken during moving, it will often make the internal devices of the machine loose, leading to poor contact and computer crash. Therefore, violent vibration should be avoided when moving the computer.

Dust removal machine

Too much dust in the room can also lead to a crash. If the floppy disk drive head or the laser head of the CD-ROM drive is contaminated with too much dust, it will lead to reading and writing errors, which will seriously cause the computer to crash.

Device mismatch

If the main frequency of the motherboard does not match the main frequency of the CPU, the external frequency will be set too high when the old motherboard overclocks, which may not guarantee the stability of operation and lead to frequent crashes.

Software and hardware are incompatible.

Three-dimensional software and some special software may not be started or even installed normally on some computers, and there may be problems in software and hardware compatibility.

Memory failure

It is mainly caused by loose memory chips, virtual welding or poor quality of memory chips. The contact fault of memory stick should be eliminated according to the specific situation. If there is a problem with the quality of the memory, the memory needs to be replaced to solve the problem.

Hard disk failure

The main reason is that the aging or improper use of hard disk causes bad tracks and bad sectors, which makes the machine easy to crash when running. Special tools and software can be used for troubleshooting. If the damage is serious, only the hard disk can be replaced. In addition, for motherboards that do not support UDMA66/ 100, we should pay attention to the setting of hard disk operation mode in CMOS.

CPU overclocking

Overclocking improves the working frequency of CPU, but it may also make its performance unstable. The reason is that CPU can access data in memory faster than memory and hard disk can exchange data. Overclocking makes this contradiction more prominent, exacerbates the situation that the required data cannot be found in memory or virtual memory, and will lead to "abnormal errors". The solution, of course, is also relatively simple, that is, let the CPU return to normal frequency.

Hardware resource conflict

Due to the conflicting settings of sound card or video card, abnormal errors can also be caused. In addition, if other devices interrupt, DMA or port conflict, a few drivers may be abnormal, leading to crash. The solution is to start in "Safe Mode" and make appropriate adjustments in "Control Panel →→→→→→→ Equipment Management". If the driver has an abnormal error, you can modify the registry. Select "Run", type "REGEDIT", enter the registry editor, find and delete all the "primary keys" and "key values" related to the driver prefix string through the "find" function under the menu, and restart.

Insufficient memory capacity

The larger the memory capacity, the better, and it should not be less than 0.5 ~ 1% of the hard disk capacity. If there is a problem in this respect, you should replace it with a memory stick with as large a capacity as possible.

Inferior parts

When assembling compatible computers for customers, a few unscrupulous businessmen use inferior boards and memory, and some even sell fake motherboards and reused CPU and memory. Such a machine is very unstable and will inevitably crash. Therefore, users should be vigilant when purchasing a machine. They can test the computer with some newer tools and software, and test the machine continuously for a long time (such as 72 hours), so as to strive for the longest warranty time.

The software crashed.

virus infection

Viruses will greatly reduce the efficiency of computers and lead to frequent crashes. At this time, you need to use anti-virus software such as KV3000, Kingsoft Internet Security and Rising. Conduct comprehensive virus detection and anti-virus, and regularly upgrade anti-virus software.

CMOS settings are incorrect.

This kind of fault phenomenon is very common, such as improper hard disk parameter setting, mode setting and memory parameter setting, which leads to the computer being unable to start. If the memory without ECC function is set to have ECC function, it will crash due to memory error.

Misdeletion of system files

Command.com, Io.sys, Msdos.sys and other files are required to start Windows9x. If these files are damaged or deleted by mistake, even if the hardware settings in CMOS are correct, it will not help. Solution: Use the startup disk of the same version of the operating system to start the computer, and then type "SYSC:" to retransmit the system files.

Initialization file is corrupted.

Because Windows9x needs to read System.ini, Win.ini and registry files, if Config.sys, au? Toexec.bat file, these two files will also be read. These files may crash as long as they have error information, especially System.ini, Win.ini, User.dat, Sys? These four files, tem.dat, are particularly important.

The dynamic link library file (DLL) is missing.

Another kind of file is also very important in the Windows operating system, that is, the dynamic link library file with the extension of DLL is essentially a * * * file, which means that a DLL file may need multiple software calls at runtime. If we delete an application, the anti-installation program of the software will record the files it has installed and prepare to delete them one by one. At this time, the deleted dynamic link library file is easy to be used by other software at the same time. If the missing link library file is an important core link file, the system will crash or even crash. We can use tools such as "super rabbit" and "optimizer" to delete useless DLL files, which will avoid accidental deletion.

There is too little space or too much fragmentation left on the hard disk.

If the remaining space of the hard disk is too small, some applications need a lot of memory to run, which requires virtual memory, which is provided by the hard disk, so the hard disk should have enough remaining space to meet the demand of virtual memory. At the same time, users should form a good habit of regularly sorting out hard disks and removing junk files on hard disks.

BIOS upgrade failed.

You should back up the BIOS to prevent accidents, but if your system needs to upgrade the BIOS, you'd better make sure that the BIOS version you are using is the same as your PC before upgrading. If the BIOS upgrade is incorrect or an unexpected power failure occurs during the upgrade, your system may not start. So be sure to find out the BIOS model before upgrading the BIOS. If the BIOS upgrade tool you are using can back up the current BIOS, please copy the previous BIOS on the disk. At the same time, see if the system supports BIOS recovery and know how to recover.

Incorrect software upgrade

Most people may think that there will be no problem with software upgrade. In fact, some components will be upgraded during the upgrade process, but other programs may not support the upgraded components, resulting in various problems.

Abuse of beta software

It is best to use less beta software, because the test software usually has some bugs or is not stable enough in some aspects, and there will be problems such as data loss, program error, crash or system failure after use.

Illegal uninstallation of software

Do not directly delete the directory where the software is installed. If you delete it directly, the registry and Win? There will be a lot of rubbish in the dows directory. Over time, the system will become unstable, leading to a crash.

Use pirated software

Because these softwares may hide viruses, once executed, they will automatically modify your system, causing the system to crash during operation.

Defects in application software

This situation is more common, such as running 16-bit application software running well under DOS or Windows3. 1 in Win98. Win98 is 32-bit. Although it claims to be compatible, there are many places that cannot be coordinated with 16-bit applications. There are also some cases, such as peripheral drivers that are normally used under Win98. When the operating system is upgraded, problems may occur, causing the system to crash or fail to start normally. In this case, you should find a new version of the peripheral driver.

Too many programs have been started.

This makes the system resources exhausted, so that the data needed by individual programs can not be found in memory or virtual memory, and abnormal errors will also occur.

illegal operation

Opening or releasing related programs with illegal format or parameters can also lead to computer crash. Please remember the correct format and related parameters, and don't open and publish unfamiliar programs at will.

Abnormal shutdown of computer

Do not directly use the power button in the chassis, otherwise the system files will be damaged or lost, resulting in automatic startup or crash at runtime. For Windows98/2000/NT and other systems, this is very important, and if it is serious, it will lead to system crash.

Conflict in memory

Sometimes it is normal to run all kinds of software, but suddenly it crashes inexplicably. It is very normal to run these applications after restarting. This is a false collapse phenomenon. Most of the reasons are memory resource conflicts. As we all know, application software runs in memory, and memory space can be released after closing the application software. However, due to design reasons, some applications can't completely release memory even after they are closed. When the next software needs to use this memory address, a conflict will occur.

It has nothing to do with configuration. The integrated graphics card of C266 63 memory 4G hard disk may not crash. The crash is either a virus, a system or a hardware problem. Specifically, what crash or boot crash? Pay attention to whether the CPU fan is normal.

2. How to prevent the computer from crashing?

(1) First, introduce the reason why the computer crashed!

Unable to start the system, the screen "freeze" is unresponsive, the mouse and keyboard cannot be input, and the software operation is abnormally interrupted. Although there are many reasons for the crash, they are all the same, and the reasons can never be separated from both hardware and software.

Hardware-induced crash.

Monitors, power supplies and CPU with poor heat dissipation will generate a lot of heat when working, so it is very important to maintain good ventilation. If the monitor is overheated, it will lead to color and image distortion and even shorten the life of the monitor. Working too long will also lead to poor heat dissipation of power supply or monitor, leading to computer crash. The heat dissipation of CPU is an important issue related to the stability of computer operation, and it is also the "hardest hit" where heat dissipation failures occur.

Improper movement, when moving the computer, will often make the internal devices of the machine loose, leading to poor contact and computer crash. Therefore, violent vibration should be avoided when moving the computer.

Too much dust in the dust killer's machine can also lead to collapse. If the floppy disk drive head or the laser head of the CD-ROM drive is contaminated with too much dust, it will lead to reading and writing errors, which will seriously cause the computer to crash.

Equipment mismatch, such as the mismatch between the main frequency of the motherboard and the main frequency of the CPU, may not guarantee the stability of operation when the old motherboard is overclocked, resulting in frequent crashes.

Software and hardware are incompatible with three-dimensional software and some special software, which may not be started or even installed normally on some microcomputers, and there may be problems in software and hardware compatibility.

Memory failure is mainly caused by loose memory, virtual soldering or the quality problem of the memory stick itself. The contact fault of memory stick should be eliminated according to the specific situation. If there is a problem with the quality of the memory, the memory needs to be replaced to solve the problem.

Hard disk failure is mainly due to aging or improper use of hard disk, which leads to bad tracks and bad sectors. This makes it easy for the machine to crash during operation.

At this time, you need to use anti-virus software such as KV300, Kingsoft Internet Security and Rising. Conduct comprehensive virus detection and anti-virus, and regularly upgrade anti-virus software.

Improper setting of CMOS is a common fault phenomenon, such as improper setting of hard disk parameters, improper setting of mode and improper setting of memory parameters, which causes the computer to fail to start. If the memory without ECC function is set to have ECC function, it will crash due to memory error.

Command.com, Io.sys, Msdos.sys and other files are needed to delete system files by mistake. If these files are damaged or deleted by mistake, even if the hardware settings in CMOS are correct, it will not help. Solution: Use the startup disk of the same version of the operating system to start the computer, and then type "SYS C:" to retransmit the system files.
