Restart or shutdown for no reason, usually because the CPU is too hot, virus, dust, bad power supply, bad memory, too hot graphics card, bad motherboard capacitors.
Enter msconfig in the start menu and press Enter, remove all (except ctfmon) checkmarks in the startup, save it and restart it (it can speed up the startup speed), generally you are running too much. , or file conflict issues.
Install 360 Security Guard, press F8 all the time to enter safe mode to scan and kill, now nine out of ten viruses on the Internet are Trojan horses, so anti-virus software can’t find any viruses, it is recommended to install 360 Scan and Kill.
The heat dissipation is not good, re-install the CPU heat sink, the contact can be bad, and the CPU fan can be replaced.
Re-plug and unplug the graphics card and memory card, the most important thing is to clean the dust near the CPU and memory, which is the easiest, or try another power supply (check your power supply, sometimes the voltage is unstable).
The capacitors on the motherboard may have exploded. Check if the capacitors near the CPU of your computer (capacitors that stand up like small buckets) are bulging. The normal ones should be flat. Buy them from the electronics market. Several of the same model were replaced for a few cents.
If the game restarts for no reason, most of it is too hot, and the graphics card or computer configuration is low, or reinstall the system.
The computer keeps restarting, why?
A computer restarts automatically, 60% of which is a power supply problem, which is caused by the leakage of the large capacitor of the power supply, which is caused by insufficient power supply. That’s it.

A problem with the memory will also cause the system to restart, and the probability of a memory error causing the system to restart is relatively high. The temperature of the system is too high. At this time, you should check whether the fan of the CPU is running normally and whether the cooling conditions are good.
What should I do if the computer restarts automatically after shutting down?
Set the system error function. Right-click My Computer-Properties-System Properties Advanced-Startup and Recovery-Settings-Startup and Recovery-In the “System Failure” column, remove the “Auto restart” option. Check whether the voltage of the motherboard battery is too low, replace the battery; set the BIOS to the factory default.
