Somewhat off-topic, but:
My PC always turns itself on. It's not anything paranormal, but the damn BIOS is so corrupt on this thing or something. When you put it into sleep mode, two seconds later, it'll wake back up. If you tell it to shut down, it'll turn off for a few minutes, then turn back on. If you hit the power switch in the pack that cuts off all power, the thing will shut down, then try to turn back on again, wasting all the power in the power supply, and being forced off. As soon as you give power to the machine, it turns on.
