Title. I have made triple sure there's no overheating whatsoever on any possible component.
It's not a BSOD, it's a complete shut down. PC won't restart unless I unplug for a bit and then plug again.
Happens seemingly at random, not even at load (3/4 times it was just chrome open with a youtube vid playing, once while light gaming).
Furthermore, it doesn't happen often, just 4 times this past week.
Cinebench stressing is fine, for as long as I could. As is Unigine Superposition looping at crazy settings. I haven't ran Memtest, could it be ram?
The mobo/CPU/RAM is new, the rest are from an older system. I suppose it's the PSU (it's old, but a very good one), but how can I be sure without having a second one to test? I don't want to spend 200$ on a new one and find out it's not that. What else could it be?
This is so frustrating.
