Dual Moniters - Anyone done it or has knowledge about it?

Alright, so a few days ago, my cisco teacher was throwing old computers away. Among one of the things I scavenged from these were near-useless generic video cards from '95 or '96. I said to myself, "you know what? In that ol' server machine of yours, you've got a top-of-the-line pci card from a few years ago. Why don't you put the generic sheizer '96 card there and get a dual display system going on?"

In my main system, I now have a GeForce256 (which, through the powers of a soldering iron, is now a blazin'-fast-for-3dmax-and-other-CAD-programs Quadro card) and a oldskewl once-top-of-the-line Diamond Viper PCI card (windows recognizes it as a TNT, which I cannot confirm or deny because I've since lost the origional box/information). Here's the problem, though: when the PC boots up, the Quadro works, but the Viper doesn't. In Windows (XP Pro, if it helps), Device Manager has that little yellow ! next to it. It says, "This device cannot start. (Code 10)"

So at this point I have a AGP Quadro card that works fine and a PCI TNT card in my system. The TNT didn't work at this point, so I go and install the latest nVidia Detonator drivers on the card(Diamond has since gone under as a video-card manufactuer, and Detonator supposedly supports TNT). Unfortionately, this didn't fix the problem either. I still have that little ! in Device Manager that says the device cannot start.

So, off I go to ChiefDelphi. Has anybody ever put in two video cards into their computer to get a dual-display system going? Were you successful? Did you use any special program? Do you have any tips/suggestions/etc that you've seen online?
