"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Absolutely nothing happens when the power button is pressed. No noise, chime, fan, or lights.

It is likely either the power supply or the start button on the front panel. G5's were notorious for the start button failing.

Have you tried powering it on from the logic board?  Do you see any diagnostic LED on the MLB lit up when it's plugged in, or after pressing the power on?

I don't know how to power it on from the logic board. And I don't see any lights on the logic board after pressing on.
