Hi guys. First post here. I just borrowed a radeon 8500 from my friend. I had a geforce2 ultra. Card decided to die on me. Now when i hook up the radeon. All i get is a black screen. You can tell the screen works when you plug in the monitor. It sounds like it refreshes but i get no video at all. All black screens. I have a old dimension. Could it be the agp speed is to fast for the motherboard? Can you think of any jumpers I might need to set? Any help would be great guys. Thanks!!!
