Quick Reference Manual for computer "blue screen" reasons

A crash is a headache for the operator. When the system crashes, the system cannot be started, the screen is frozen, the mouse and keyboard cannot be input, and the software is interrupted abnormally. Although there are many reasons for the crash, the root cause is never the same as hardware and software.

Crashes caused by hardware

[Poor heat dissipation]

Monitor, power supply, and CPU are very hot at work, so maintaining good ventilation is very important. If the monitor is overheated, it will lead to color, image distortion or even shorten the display life. Too long working hours will also lead to poor power supply or display heat dissipation, resulting in computer crashes. The cooling of CPU is an important issue related to the stability of computer operation, and is also the "hardest hit" of heat dissipation failures ".

[Improper migration]

In the process of moving a computer, a great amount of vibration often causes the machine's internal devices to loosen, leading to poor contact and computer crashes. Therefore, violent vibration should be avoided when moving the computer.

[Dust killer]

Too much dust in the machine will also cause a crash. If the soft drive head or optical drive laser head is contaminated with excessive dust, it will lead to read and write errors, serious will cause the computer to crash.

[Device mismatch]

If the clock speed of the motherboard does not match the CPU clock speed, when the old motherboard is over-frequency, the external frequency is set to be too high, and the operation stability may not be guaranteed, resulting in frequent crashes.

[Hardware and software incompatibility]

3D software and some special software may not start or even be installed on some computers, and there may be problems with software and hardware compatibility.

Memory failure]

It is mainly caused by loose memory, virtual soldering, or memory chip quality. Memory stick contact faults should be ruled out according to specific circumstances. If there is a problem with the memory stick quality, the memory should be replaced to solve the problem.

Hard Disk fault]

This is mainly because the hard disk is aging or the bad sectors and sectors are caused by improper use. In this way, the machine will easily crash during running. You can use special tools and software for troubleshooting. If the damage is serious, you can only replace the hard disk. In addition, for boards that do not support udma 66/100, you should pay attention to the setting of the hard disk running mode in CMOS.
