Hi i have a blue g3 with a new working mother board. It has a 400mhz and 448mb of ram. It will not get video. I zaped the pram nad replaced the motherboard. Could it be the video card? It comes up with nothing on the screen. I also chimes just fine. It also has a formated 80gb drive. Please help thanks.

Yes! I would say it has something to do with your video card. VGA is the only thing that carries it all. Try it with yourself I actually base it on my own experience.

First of all you can reinstall your video card driver and then you can check your monitor video and then if your monitor do not work perfectly then you can change your video card.
