I have a computer that shuts down and reboots all by itself.
I have hooked up the hard drive to a new power connection (using the same power box) and that hasn't helped. I suspect the power box and or the motherboard or some temperature setting that turns the computer off. I have 2 questions:
1) Could it be anything else?
2) If it is the power or the motherboard or a temperature setting how best do I go about checking them?
