Hello everyone I am really at my wits end. I have a PC that kepts on rebooting all by itself. weather in standby or working on it surfing the web. There is no warning, it just reboots. I have change the CPU, Fan, Hard Drive, and Ram - no help I have also remove everything from case to base setup (mobo,ram. video, HD and Floopy) - NO HELP. Then I removed the MOBO out and check for something that may be shorting it out, found nothing. I then replaced it back in the case with insulated washers on the screws. Still no Help. It looks like the MOBO is bad. Any ideas?
