2.: Memory reason. When the memory is in loose contact with the motherboard slot, it may also cause the computer to shut down automatically. It is recommended to check whether the memory is tightly inserted in the motherboard, or change the slot to see if there is a crash.
3.: Power supply problem. Insufficient power supply is also an important factor leading to the automatic shutdown of the computer, but from this configuration, the possibility of this problem is very small.
4:
Software factors. Computer shutdowns caused by viruses or Trojans also abound, especially the recently popular shock wave, which will lead to system restart and shutdown after being infected with viruses. If you are using Windows.
2000 or Windows
XP system, I suggest you use anti-virus software to patch the shock wave in time, and general problems can be solved.
The computer automatically shuts down for no reason.
5. Check whether the CPU is overheated.
Is the CPU fan frame stable, if it is broken?
Or unstable, unable to hold down the CPU fan, insufficient heat dissipation capacity of the CPU fan, too high CPU temperature,
The automatic protection function of the motherboard will automatically turn off, and the screw of the CPU fan has long been loose!
6. The motherboard capacitor is deformed, which may be caused by the unstable host voltage and can be replaced.
7. When the host power supply fails or the voltage fluctuates greatly, increase the AC regulated power supply.
8: It is not recommended to kill viruses in safe mode. At present, it is not possible to disconnect the network and reinstall the system to eliminate system problems.
There may be too much dust on the fan.
Cause automatic shutdown
It is normal to clean up the dust! ! ! ! ~~~~~~
