So I've posted about before, but now I've narrowed it down a little bit. So my GTX 560 just randomly overheats for no reason. I'm not running anything really demanding or anything when it happens. And I'm running high end programs and it runs just as normal. For some reason, every couple of hours out of nowhere it just starts revving up in speed on the fan and the temperature dramatically increases. It stays like that for about 3-5 minutes and then randomly stops just as quick as it starts.

Does anyone have any idea what could be causing this?
