Windows 7: Problem installing ATI HD 5770 on Dell XPS 8700

Problem installing ATI HD 5770 on Dell XPS 8700

Am seeing a problem I haven't seen before. When I put the ATI HD 5770 card in the Dell XPS 8700 and reboot the computer to install the driver, I see a black, blank screen, no video. I know that the system is booting from the sounds, but no video. I've tried using both DVI ports on the back of the card, booting in safe mode, but just not seeing any video.

The only thing that I can think of to try is uninstalling the previous card that's being replaced, Nvidia GT 720, and booting with the new card installed. But I'm not sure that'll help, I just don't understand why I'm not getting basic, legacy video when I reboot the computer with the HD 5770 installed.

Any ideas?
