My PC's had a new qwirk as of late. It seems now whenever I try to play a game, watch movies, or stay on the computer too long, it automatically shuts off and tries to restart, but before it can log on it restarts itself and continues this endless routine. If I leave it off for about 10 min, I can get back on and use it normally, and a message will come up saying that the PC has had a system error. And then, it's only a matter of time or until I try to play a game or watch a movie until it restarts again.
Sometimes it restarts after a certain amount of time, and other times it resets randomly.
I decided to open it up and sometimes one of the little fans on the motherboard is not spinning (happens about 60% of the time when I start up the computer.) I usually just give it a touch and it spins around and starts working normally. I am not sure if this could be the cause of the problem, for even if I do get the little fan to spin, it again is usually just a matter of time before my pc restarts regardless, although it does seem to lengthen the amount of time it takes for it to restart in it's endless cycle.
Anyone have any idea as to what's going on!?
Thanks for any help that can be given!
