Uninstall Drivers, Insert New Graphics Card. install New Drivers|||If you remove the old one and install the new one, the computer will automatically recognize that the old one is gone and eliminate it for you. If the old one is an on-board one, you may need to access the BIOS and tell the computer to disable it. Some motherboards automatically disable the on-board when they detect the new one.



If you are trying to run 2 monitors simultaneously, just make sure that both of the video cards are identical.|||Uninstall your video drivers for current card. Shut down PC and remove old card. Insert new card and make sure it is seated properly and all connections are good. Fire up PC and install drivers for new card.|||If the old one is AGP the motherboard have only one slot but have many PCI and you can have 2 video cards one agp and one pci.

If you buy a new agp then install first the software or drivers next go to control panel,system,devicemanager and there uninstall the old one,then shutdown your pc then install the new agp card then boot your pc.
