Okie here is my problem. I wanna upgrade the video on this computer. I have a radeon 7500 pci card and a trident pro vidia something card. The Radeon is what I want to run but the comptuer locks up in the bios screen. And when I boot up with the pro vidia the comptuer gets to windows and goes back to the video that is built in. I want to just run the radeon. Anyone have anything that can help me trouble shoot what is going on?
