A G4 tower (gigabit ethernet dual 500MHz) landed in my hands the other day from a friend who discarded it because it had died. I'm trying to decide if it's worth the trouble and expense to resurrect it for use as a home server. She reports that she was using it and "it just turned off" and when she pressed the power button, the computer produced only a soft clicking sound, but nothing else. Now, when I press the power button, the power button illuminates for only as long as I'm pressing it, then the illumination fades. It may be too much ambient noise where I am, but I don't even hear the soft clicking sound she was reporting. Does anyone have any thoughts on where to begin in diagnosing this? I'm willing to spend some $$$ to get it working again, but I don't want to blindly through money at it.
