I had a problem similar to that with my old system. One day it just decided not to display any video whatsoever. So I took the machine with me to work and proceeded to test it out. I discovered that somehow my AGP slot had fried, or some such thing. As my GeForce2 MX worked in a different machine but not in mine. I then tried a PCI card in my machine and it worked fine. So I ended up using a Radeon PCI card until I got the sys in my sig.

My reccomendations are to try a different AGP video card. If that doesn't work, use a PCI one. Then go into your bios and make sure that AGP video is enabled, if it isn't, then enable it. If it is, well I guess you're pretty much screwed, and have fun finding a PCI card.
