As title suggests.
Coming home the other day I find my PC started to restart out of nowhere, with no warning before or errors afterwards.
I haven’t changed anything and haven’t had this problem before.
Any suggestions on what to do?

UPDATE: Memtest got through 2 out of 4 passes in under 4 hours before I got fed up with waiting, which in itself seems a good sign since it didn’t restart there.
Event viewer showed one odd Event:
The process C:\WINDOWS\Explorer.EXE (ANDROID-17) has initiated the restart of computer ANDROID-17 on behalf of user ANDROID-17\smuld for the following reason: Anderer Grund (geplant) Reason Code: 0x80000000 Shut-down Type: restart Comment:
No idea why because automatic restart is disabled.
Make a bootable USB or CD with memtest86 and boot from it. Then let it test your memory. Based on what you’re describing, it’s a good candidate for a fault.
Usually a memory fault results in random blue screens on most crashes, not in a consistent pattern of going dark and booting again. Still, it could be memory, and it doesn’t hurt to try it.
That’s a fair comment, but there’s a secondary reason I suggested it, eliminating the OS as a potential cause. If it still crashes while booted into memtest86, it’s much more likely to be a hardware fault, on the other hand, if it stays running overnight, it’s more likely to be software.
Well it ran fine for 2/4 passes in under 4 hours before I got fed up with waiting and canceled the rest to do it tomorrow while I’m gone so that seems promising!
Good point.
I believe the default behavior is to crash dump and restart on BSOD. Holding on BSOD display must be configured.
Usually shows on the screen for at least a moment, but yeah, if it writes the crash dump fast enough you might not see it.
Got it, thanks! Trying that now
