I've have a friend who claims their computer randomly turned itself on a few times during the night. They also claimed that they went away on a long weekend and came back to the computer being turned on (they turned it off when they left). When I checked out the computer, it would turn on but not boot up. Once the power came on that's where things stopped - the initial memory scan nor device loading processes never take place. I have ruled out a defective power supply by installing a fresh one in the system and getting the same problems.
What do you think is wrong with this system? I am wondering if there was a power surge that damaged the motherboard, or perhaps the BIOS needs to be reset. If the BIOS needs to be reset, where can I find the reset switch/pins? This is an emachines computer and I have not been able to locate the BIOS reset.
Thanks for any help that can be offered.
