Problem solved.
Thanks You Everyone who helped. I appreciate it very much. I learned a few things as well.
It was the video card.

Thanks again,
Peter

Problem with my G4 tower M5183.
It won't boot the monitor unless I open the side and push the reset button.
I tried changing the battery; another monitor;another video card; erased the HD and installed OS X10.4 again. Same results with all these options. ?????
Can anyone help on this issue, please.
