I have a PNY Geforce 6200 AGP and a eVGA Geforce 6200 PCI. When I install the PCI card, it recognizes the card (boots from AGP) and the screen goes blank. When I reboot, it hangs from the Windows screen. When I run just the AGP card, it works. When just the PCI card, it works. Any ideas? Is it because Windows recognizes the video card as the same one (uses same drivers) and so it doesn't load?
