Im helping a friend install his new video card. Its an ati 7000 PCI card. He has a compaq presario 5000 series computer with onboard video. The compaq site says that by installing the new card it should automatically disable the onboard video. It doesn't happen. I've tried uninstalling it through the hardware manager, there's no way to disable it in the bios and every time I put the card in i just get a blank screen when it boots up. It doesnt seem like its getting throught the POST. Any ideas on what i can do to solve the problem? Thanks!
