How do I fix grey screen/computer is not starting up?
After being away for a year I returned to my G4 and on the second use found it refused to start up. Plugged it in and it will chime when start is held, but stuck on grey screen with apple mark in center. Called Apple and they said to try to install from disk. I found the old Panther disk, inserted it and held C. It was installing, however it got held up on the checking disk step (said I had 11GB free though). Tried disk utility and just hung up with a spinning icon (checking disk).
Apple said it is probably a hardware problem, but they don't support this model anymore. I have been searching for info and found references to logic board, logic board battery, PRAM and RAM but am not really sure how to diagnose the problem.
Any suggestions on where to begin?
Is this a good question?
