For some reason my computer keeps restarting itself at increasingly shorter intervals. At first, I assumed it was a problem with my video card since it would only restart while playing a computer game, but now it's restarting itself every few mins. no matter what I'm doing. I thought it might be some kind of overheating problem, but checked all of my fans and they're all working properly. Ran a full virus scan, and haven't installed any new hardware or software lately so I can't figure out what it's doing. Anyone have any ideas?
