I am sort of befuddled as to why a friends computer will not turn on. There is a green light on the mobo indicating that there is power to the computer, but no luck starting up. I have replaced the power button switch on the front of the computer, checked all power connections to the power supply and motherboard, made sure the outlet was good, and am at a loss as what to check for. She says that there was not a storm before having this problem, but did tell me her daughter shut down the computer by just pushing the power button. I didn't think it was that much of a deal seeing as how the computer is 3 yrs old, but I could be wrong. Any help would be much appreciated.
