I have a Compaq DeskPro EN series with an AGP slot. The slot is bad and I want to put a PCI video card in the PC. However, when I do, I get the beep code for no video and I get no video and the system goes no farther in the boot process. If I remove the PCI video card it boots fine but I still have to deal with the defective AGP slot which gives me bad colors and inconsistent flicker no matter what card is in that slot. There is nothing in the BIOS that jumps out at me as a way to disable the AGP, any suggestions or help would be great.
