Have you opened up your machine, removed video card and made sure it is replaced and seated very tightly? Next thing is try a different card.

tiiight

I have an agp 6800gt nvidia card here. It won't work though. I am assuming the power supply in the Power Mac is too small. It's only 180w I think.

I have a 480w at home I can throw in.
