According to c|net's review of that computer, there is no dedicated video card slot in that computer model. The only video card that will work in that machine is a ''PCI'' video card in one of the three PCI slots. That's PCI, not ''PCI Express,'' and not ''AGP.''

No, you cannot add a PCI Express slot to the motherboard.

I'd return the incompatible PCI Express video card and purchase a good PCI video card.
