Welcome to the Se7enforums! mgodfrey
Also welcome to the continuing AGP nightmare since more and more will continue to see problems with Windows properly detecting the old form of video card there with the newer PCIe geared driver sets.
The drivers go on while you may simply have to reseat the card to make sure that it is down fully in the slot. If you have an onboard graphics chip at all make sure that is turned off in the bios and disabled in the device manager as well since that will conflict with any separate card installed.
The PCI/AGP setting should be at AGP as well while you are in the integrated peripherals or onboard section of the bios setup as well depending on which bios is being used. Hopefully the card you have there is not suffering any defects.
