Quadro 4000 SDI throwing a fit with WDM drivers in dual-PCIe

Specs: Windows 7 Professional, X5550 x 2 / 24GB
Dear all:

I've come across an odd issue here on the box described above.

Current setup has a single NVIDIA Quadro FX4800 running on the board's main PCI-e x16 slot. That works fine.

However - ideally - I need an SDI-compatible video card as well - but this brings up issues. I have an older NVIDIA Quadro FX4000 SDI PCI-e card that should do the job, but Windows 7 doesn't agree with it.

In a multi-monitor setup, running one DVI connection from each card to each monitor, these two video cards will only run properly in safe mode with generic VGA drivers. If booting normally, the monitor on the FX4000 will drop its signal every second - and if I'm lucky, I'll see the desktop for a fast enough split-second to read "Display driver NVIDIA Windows Kernel Mode Driver, Version 191.56 stopped responding."

Any ideas? Driver compatibility conflict?

I'm going to shove this card alongside an ancient 8800 GTX (in an Asus P5B Deluxe) just to see if it repeats the problem (in case it's a genuinely shot video card).

I ran the test on the P5B box (not the same box I had in mind, but effective enough) that already had the latest Nvidia drivers loaded on it for its current card.

Once the unit booted up and loaded the drivers, the screen began flashing uncontrollably as described earlier.

Dead card.

See the operating system requirements for the NVIDIA Quadro FX4000 SDI PCI-e card here:

Seems it is for "Microsoft Windows NT" so there will probably be no suitable Windows 7 drivers.

Always pop back and let us know the outcome - thanks

I spoke with PNY today. They say the card is compatible with 7, despite its age.

They also agree that the failure is due to the card's hardware; the generic Windows safe mode driver does not access the faulty portion of the card/chip.
