Hey people, I've got a problem that occurs sporadically: random power loss and restart.
Every so often my computer (desktop) will just lose power, then restart a second or 2 later. Loads on it aren't especially high when this happens, but it will usually happen while playing a game. I don't have any extra peripherals, just mouse, kb, headphones, and my components are well under my power supply's capacity of 700W. Recently I actually replaced a failed water cooling unit with a normal heat sink, and went from two fans and a pump to one fan with that change, so it should be even further under than it was before. Problem has occurred before and after the switch with similar frequency.
It's not overheating either, I've checked with CoreTemp. This doesn't happen all that often, maybe once every week or two. Thoughts? I think I have a fishy power supply but want a second opinion.
