...traded out the the vid chip with one thats compatible...

Which cards, exactly, did you try? There were only a few Macintosh-compatible PCI cards released that would work with the PowerMac B&W G3 machine.

Macintosh computers cannot accept video cards that are not specifically compatible with Macintosh computers -- i.e., an Nvidia card from a Windows PC will not be compatible with any Macintosh computer.
