PC boots fast but restarts after 10 minutes or so

[jhednj]

Hi, I've recently encountered a problem after reinstalling windows 10. When I boot my computer, it boots fast and it doesn't even load when I login to my user, it just straight up shows my desktop after entering my user password, no loading icon or anything. After 10 minutes or so it restarts by itself, no BSOD or any warning. I was hoping if anyone knows a fix for this because this problem has been going on for days.

Could it be my system or is it windows 10 itself?

I'd check the temperatures. If the CPU is getting over 70 degrees C, that could be the problem. You should also check for corrupt system files; you may have to boot to Safe Mode to do that. Hit F8 about once a second after powering on to get to Safe Mode, then open an administrative command prompt, then issue these two commands:
. SFC /scannow
. DISM /Online /Cleanup-Image /RestoreHealth
