[QUOTE="MacHeadCase, post: 357243"] Could be the analog board acting up... [I][B]Edited to add:[/B][/I] The analog board is what controls the video card. I had a grape iMac whose analog board went gradually belly up and it refused to start up once it was completely gone. Do you have the CDs that came with the iMac? In the set you should find one that is called [I]Hardware Test[/I]. Insert it in the optical drive and restart, holding down the [I]C[/I] key. Run the test in [I]Extended[/I] Mode if you can.
