I had a PC to repair that had similar symptoms. After wrestling with all software and hardware suspects, I went back to basics and found the problem. I checked the "turn on" button and the "reset" button by a multi meter resistance test. To my surprise both switches showed erratic resistance. When I tilted or bumped the case, resistance varied from 1 ohm to infinity whether the buttons were pressed or not. When I did an autopsy on them, they were both internally full of minute carbon particles. | ||
