First try card 2 in slot 1 to ensure both cards are in fact working. Second completely un-install all the graphic drivers and re-install the lastest version. If there's no change in your system you should consider backing up all your data and doing a complete install of windows 7. Does upgraded mean you did an in place upgrade to windows vista 64? As this would not be my first choice. Assuming you have an upgrade version of windows 7, you do know you can do a clean install by selecting "custom install" instead of upgrade? I would remove the 2nd video card until after the installation, because I want to be sure the system recognizes the 2nd card, then reinstall the catalyst drivers. Good luck
