I haven't had to work on computers in quite awhile, actually since the era of this Mac probably, so I am not remembering things I probably should. I use my G4/867 as a iTunes and job file server and love the damn thing. I turned it on tonight to locate some files and all was fine, it came right up the way it always has. Then after about 5 min it shut down completely. When trying to restart it, the on/off glow-plug button lights for a moment but doesn't start the machine. Absolutely nothing happens, no sounds, no screen flicker, sad mac, etc. I realize it's an old machine that's served its purpose well but I would still like to keep it running if possible. Does anyone know what the probable cause could be? I love this old thing. Hope someone can help, thanks!

Have you tried resetting the PMU?

It does sound like power supply failure, it was quite common reason for MDD's to fail.
