Well, I was unable to get my hands on a spare graphics card, but I did take the graphics card from the server and put it into one of my desktops; the video card worked fine.
....* a little later *....
I figured it out (kinda). I figured that if the card worked, then the problem was between the riser card and... um... other stuff (wow, I am so good at this). So, I plugged a cable into the NIC that was in the other riser's slot, and when I turned it on the little lights on the card came on, so apparently the riser card was good. So I took out the NIC and put the graphics card in the other riser slot, and it worked. It is kind of annoying to only have one riser slot, but I imaging I can find/buy another one. Of course, there is the possibility of fixing this one. What typically fails on those things? I shall check for scrapes across the circuit board, but we shall see.
Edit: It turns out that it was just a bad PCI NIC that was messing everything up.
Edit 2: Oh, and thank you for your help.
