Does the motherboard have onboard graphics? If that is the case, you may have to switch something in bios. (using the onboard, obviously)
If the slot is agp, there may be a jumper that you need to change. Look into it in the manual that comes with the board. (you may be able to find the manual online, and if you don't know the board I think tomshardware.com has an app that finds all your computer info...)
good luck and if you need any help just holla back,
