What causes a computer to reboot itself?
A. It could be caused by a lot of things, but it is usually a hardware problem, especially if it occurs randomly. A noisy power supply, loose screw under the motherboard, bad CPU fan, and memory, expansion boards, socketed chips, and cables that are not fully seated are among the common causes. The motherboard could be cracked—these are usually hard to find. Our motherboard FAQs (http://duxcw.com/faq/mb/mb.htm) may help.
