It started a few months ago. I was playing a game and the PC suddenly shut off and restarted by itself. The shut off seemed as if the power went out or the plug was pulled - there was no blue screen, nothing in the event viewer log. Just shut off and restarted itself. But the power did not go out and I have my system connected to a good, sine wave UPS. I thought at the time that it was the PSU, so I replaced it under warranty.
Now it is starting to happen again randomly. I had another game running and it did the same thing. I started running an overclock on my CPU a few days ago. But I am not sure that is the problem because I think it happened a week or two ago as well, before the OC was applied. Also, OC problems tend to give me a blue screen whea uncorrectable error, not a sudden shutdown + restart. Anyway, I've set it back to default speeds for now.
Could it be my motherboard, CPU, RAM? Maybe a bad HDD? I have a D drive with 1000+ reallocated sectors. But my OS and the game are on a different, SSD drive. Any chance that it is not my hardware? Could it be caused by Windows, Fast Start, C states?
How can I find out what the cause is? I plan to run Memtest86 some more - so far it has done 2 full passes with no errors.
