While troubleshooting several Windows XP computers, I notice that some of them reboot unexpectedly after a certain amount of time for no good reason. I already checked the Power Options and no known viruses seem to be involved. These computers are custom made. At first I thought there was something we missed or mishandled in the assembly process, but recently this same problem happened with a fairly new, brand name computer. Any ideas on why this might be happening and how to resolve it?
