    I am having a booting problem with my machine. It was on and running fine. I was opening an audio file that I had opened numerous times before, and it was taking a while so I left that room and when I came back to the room and it was off. I tried restarting and it wouldn't power up. The light flashed momentarily when pressed, and stays on if I hold it, but nothing else powers on; fans, drives, etc. I checked the power supply with a volt meter at pins 1 and 12 and received a 5 volt trickle of power which makes me think it's not the power supply.

    I've reset the pmu, tested the battery disconnected my secondary storage drive. Nothing seems to make a difference.

    Any suggestions???

    I had the exact same problem with a Blue and White G3 that I used to own; turned out to be a bad power supply. You might look into getting a new one.

    Yeah, that's what I'm afraid of. I don't want to get one and have that not be the problem, unless I can return the PSU.
