[Videocard filter] I am trying to help a friend run a gtx265 and gtx295

I recently helped a friend gut a PC and put a bunch of new parts in it. I consider myself no slouch to these things as I've been tinkering with computers for almost 20 years, and majored in Computer Science to boot!
However, I could not for the life of me get both of these video cards to work, non-SLI, such that my friend could run two monitors off one card, and use the third as a dedicated physix card while also giving output to a 3rd monitor (a tv). 750w power supply.
Help!
It may be possible that I did not connect the power supply correctly to one of the cards (I may have had a drink or 3) and this could be the simple solution.
However, I am unaware if somehow this just isn't possible (running this kind of set-up). If I recall correctly, both cards worked by themselves, giving dual-output, but I'd really like to help my friend achieve the goal of 3 distinct outputs.
Could this possibly be a driver issue?
Running Windows (XP or 7 I can't remember) using an AMD A3+ chip, again 750w power supply.
Help! =))

Response by poster: No beeps, codes, etc. The drivers won't show three displays when all three are plugged, but the two cards work when 2 outputs are plugged into one card, or one in each.

Does it show 2 outputs with any mix and match of the 3 displays?

Response by poster: RustyBrooks, to the best of my memory it does.
I am sorry if I am thread-sitting inappropriately.

Best answer: So, first off, are you sure the 295 can't do 3x out on its own?
Second, have you checked BIOS settings to make sure the second PCIe slot is enabled? It might be shut off to make sure the primary slot is working at full speed (as using both sometimes means that the primary slot slows down). Or, since the cards are not the same, maybe you need to disable SLI in BIOS (if there's a setting for that).
I'd also try updating motherboard drivers, then removing, cleaning and reinstalling the NV drivers. (And check for any PCIe or GPU issues known to exist with that motherboard).
You might also boot into XP or Linux and see what happens outside of Win7. Even just to look at the dmesg output in Linux and see what the hardware detection is reporting.

Best answer: Also, the GTX295 is a dual-GPU card. So maybe that's the problem. Potentially Windows thinks you're ALREADY using two cards? At least enough to prevent if from trying to use a "third", even if that's not how it looks in the control panel, etc. Device Manager might reveal more.
Otherwise, what brands are they? If one of the brands has good support, I'd just ask them.
