Windows 7: Card not being recognized at all

Card not being recognized at all

I have an ATI Radeon 4650 card (dual DVI ports) which is working perfectly. That is in a PCIe slot on the board. I have two monitors running well. I also have third monitor which I'm trying to get running but can't. I've installed one card in the second slot (PCI slot) that is the NVIDIA GeForce 8400 GS PCI card. It too has a DVI port and also a VGA port. I'm aslo running Windows 7 enterprise 32-bit.

The problem is that the PCI card is not even being recognized as being connected to the system. It's fan is spinning, but Windows refuses to show it in the Display Adapter listing. I've also tried placing it in the other available PCI slot on the board and it's not being recognized there either.

I've scanned for hardware changes and nothing shows. I try installing the latest driver version from NVIDIA but it refuses to install b/c it doesn't see any card that the drivers would work for. I've even tried unzipping the driver package, and then manually installing the drivers as "legacy hardware" and it still will not see the drivers or card.

I'm stumped. I also had a problem getting Windows 7 to recognize an older VGA card at the same time with the ATI Radeon card. Well, it saw both cards, but would not turn them both on at the same time. If the VGA card was in it would only display on that adapter and not the ATI one. If you took the VGA card out then it would display on the ATI one. But it won't show to all the displays. It's almost as if you can only have one graphics card that Windows 7 will recognize.

Anyone have a clue how to get both cards to be recognized at the same time? Even if I have to use the VGA one, that's fine. I just want all three monitors working again.

Funny thing is that they worked perfect under WinXP...yet Windows 7 seems to be backwards in it's support. Anyone? Desperate need of help

Could the problem be that I'm trying to run an ATI card and an NVIDIA card at the same time (two different manufacturers)?

Are they any ATI cards or NVIDIA cards that are PCIe that run at least 3 displays at 1920x1200 and fit within a minitower (Dell Optiplex 745)?
