Hello Everyone.
I have G5 2 ghz dual core tower. I was running disc utility and when I came back to check the machine, my Apple Studio display was black and the power button was flashing 3 times about every 3 seconds. I noticed the power button on the tower was also flashing the same way. I re-booted - same thing. Unplugged for 24 hours, hit the reset button on the logic board, plugged in and rebooted..... same thing...machine powers up, fans come on and then nothing, still 3 flashes on the power buttons. This is my first G5 and I have never had trouble until now. I'm not sure what the 3 flashes means.... anyone ?

Thanks as always...
