1. What caused the computer crash?
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. 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 UDMA 66/ 100, we should pay attention to the setting of hard disk operation mode in CMOS.
CPU overclocking improves the working frequency of CPU, and 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.

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.

Hardware resource conflict is due to the setting conflict of sound card or video card, resulting in abnormal error. 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 machines for customers, a few unscrupulous businessmen use inferior boards and memory, and some even sell fake motherboards and used CPU and memory. This kind of machine is very unstable, and a collision is inevitable. Therefore, users should be vigilant when purchasing a machine. They can use some newer tools and software to test the computer and test the machine continuously for a long time (for example, 72 hours) to strive for the longest warranty time.
Software-induced crash.
The virus infected with the virus will greatly reduce the working efficiency of the computer, leading to frequent crashes. 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.
Initialization file is corrupted. Because Windows 9x 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.
