PC restart itself

[Dupam]

I have a problem with my pc, it restarts randomly, the temperature is ok, cleaned of dust, drivers - windows upToDate I have not downloaded third party driver software through Windows everything updated, viruses - malware, etc. no, I reinstalled the pc, tested ram with memtest86, each one placed separately on separate slots one by one, no problems, I made a benchmark on the cpu, gpu has no problem, I tried only with the mouse and only the keyboard, I thought some of the slots would not be a problem but no. Now I use one ram because when I use both restarts it does much more often even as soon as I turn on the pc, on windows events it gives me a kernel 41 critical error. Some told me could be memory frequency on bios or updating bios, removed cmos battery and insert again, when enabled XPM profile restart immediately i save and exist from bios but its saved and XPM enabled but restart much often. Haven't touched the pc 1.5 years when replaced psu for better one never opened the case and since 2 weeks restart issue occured. When pc is off for 20-24 hours runs few hours but once restart will restart at least 5 times in 10 min.

If you are overclocking hardware, then set the overclocked hardware to it's default configuration settings, as the overclocking can cause BSOD and PC rebooting by itself.

If you have a good working PSU connect it to your PC to see if the PSU is the cause of the problem.

Windows (by default) will auto-restart the PC if a 'system failure' occurs, basically this means a failure in any of the critical Windows processes. You can stop Windows auto-restarting, though the system will then halt and will have to be manually restarted. It's possible however, that when it halts (and doesn't restart), you may be able to read some error messages.

In the Run command box type the command SystemPropertiesAdvanced and press Enter. It will open on the Advanced tab (if it doesn't click the Advanced tab), click the bottom Settings button (in Start up and Recovery). In the window that opens you'll see a checkbox labelled 'Automatically Restart' (it's under System Failure), uncheck that and then click OK. Windows will no longer auto-restart when a 'system failure' occurs.

Recheck what power button does and wake up protocol for mouse and keyboard. Disable Fast Start.

I remember coming across a similar issue by a member on another forum: Solved - PC turns on immediately after shut down

If you have modified your BIOS recently, especially to overclock, it may be worthwhile to “restore optimized defaults” of the BIOS.

Please also note that disabling fast startup will likely lead to a slower startup of windows. (Fast startup places computer into hibernation mode rather than a complete shutdown when you “turn off” your computer.)
