One of my gigabit Ethernet G4 towers is playing up. It has happened three times now. If there is an interruption in the power then it will not restart without encouragement. The first time was a power out. I eventually removed the PRAM battery and unplugged it. Left it for a couple of days, put everything back, then it restarted. The second time. I turned the power off to service some house wiring. I had forgot to shut down this computer, so had he same trouble as before, but eventually it started. Third time my son pulled the power with his foot. Now it won't restart. This is annoying as we often seem to have power outs here in Texas (so much for the hi tech USA). Anybody know if this kind of behavior is power supply or motherboard related?
