when im doing something my computer randomly restarts. first it hought it was a virus so i scanned and found nothing. then i thought maybe the cpu was over heating (b/c i told it to to restart when CPU reaches 60 C)...so i got Sandra software and its basically telling me that my CPU is at 45C right now and i have basically nothing openeed up. so do you think it is the CPU overheating or not? i don't think it is because the motheboard is suppose to beep when it reaches that temperature...last time it did that...any ideas?
