I have seen this. I build computers for fun also :)

If your video card is an AGP card, go in your bios and check two things.. Make sure it is set to init the AGP slot rather than PCI and also make sure that it is set to assign an IRQ to the AGP slot. If you (carefully) fish around in your bios, you should find those settings, wording may vary. If its a PCI card, I believe it still needs to have the IRQ assigned to it.

I could tell you more if I knew what motherboard and vid card you have.

If you don't know how to get into your Bios, I suggest you may want to find someone to work on it for you. You can really hose your machine by fooling around in there if you're not careful.

Erm, it would also help if I knew what OS you are using. Windows98 and later should have built in drivers for most common video cards though in most cases, you should still get to the card makers site and download the latest revision.
