I have a radeon 9800 256mb agp card which I am attempting to run on my p4 msi motherboard I have windows xp home, the problem I have is I installed the drivers for it and when I restart the COMPUTER It does not work. I made sure all the connections are right my computer recognizes that the CARE is there in device manager but has a question mark on it. when I switch the crt connector to the new cards nothing but a blank screen. everything is brand new so I don't think it is mechanical.Do you also have onboard video? If so, you probably need to access your BIOS settings and disable onboard video. You should also have uninstalled any drivers for the original card before powering down to FIT the new one.Ok I first installed the drivers for the new card, then I went into the display settings to disable the drivers for the onboard video after that I restarted with the new card plugged in and nothing happened. then I plugged it back into the onboard again, and I saw a picture until windows started to load then the screen tured black. ok? what happened now? then I TRIED to load into safe mode but that didn't work, then I tried to load it in the option that loads the computer from the last known good configuration known, and that did not work either and now I am stuck. I don't see any options in the BIOS for DISABLING the onboard video, the only thing I saw was an option to switch video to PCI or AGP it is and MSI pm8m-v chipset is VIA P4M800
