pc keeps restarting by itself, temps look fine

My desktop reboots out of nowhere maybe twice a day, no blue screen, just goes black and restarts. CPU and GPU temps are normal in HWMonitor. Happens even when it's idle. Where should I start looking?
randomly restarts

is it a clean restart or does the screen just go black like the power was pulled? if it's the first, windows is probably crashing and rebooting before you can read the error. search for advanced system settings, Startup and Recovery, untick Automatically restart. next time it'll sit on the blue screen and you get a stop code to search. if it's the sudden black, power supply is my first suspect, especially if it happens when gaming. event viewer will show Kernel-Power 41 for that, but that only says power was lost, not why. run windows memory diagnostic as well, bad ram does this too.
