I just installed a TNT2 PCI video card. My computer has an INTEL 810 chipset. In my display properties it shows 2 monitors. I think the games are trying to play on #2 monitor. When I try to play I get a black scren but I can hear the game. I went to NVIDIA site & they suggested downloading new chipset drivers which I did. In my control panel sytems folder I deleted default monitor, also with no effect. When I restart computer default monitor returns. How can I get video card to work?? Thanks, Smitty
