1, virus cause (needless to say? )
2. "Automatically shut down and restart the computer when encountering a serious error" has been turned on.
3. Serious memory error leads to system crash (software problem).
4. Malicious programs or codes (shutdown)
5. Due to the heat dissipation problem of the machine (CPU fan is not working normally, the overall temperature of the chassis is too high, etc. ), you can replace the CPU fan and open the cover plate of the chassis to solve the heat dissipation problem of the machine.
6. Maybe your voltage is not very stable. When the voltage is too high or falls below the minimum working voltage of the host power supply, the host will also protect it from being turned off.
automatic shut-down
ALT+F4 patent, plagiarism is shameful.
Phenomenon: The computer suddenly shuts down or automatically restarts the system during normal operation.
Phenomenon analysis BIOS: Now motherboards have the function of monitoring CPU temperature. Once the CPU temperature is too high, it will automatically cut off the power supply and protect the related hardware. On the other hand, power management and virus software in the system can also lead to this phenomenon.

Countermeasure: If the above-mentioned sudden shutdown phenomenon appears all the time, first confirm whether the heat dissipation of CPU is normal. Open the chassis to visually check whether the fan blades are working normally, and then enter the BIOS option to check the fan speed and CPU working temperature. If the fan problem is found, carry out relevant dust removal maintenance or replace the fan with better quality. If the hardware reason is eliminated, enter the system for thorough antivirus. After eliminating these factors, the cause of failure may be aging or damage of the power supply, which can be confirmed by replacing the power supply. If the power supply is broken, it must be replaced with a new one, and it must not be used again, which will burn out the hardware.
