Dual Vid Card setup not functioning properly.

Relevant system info:

AMD Athlon K7 2000+
2 GB DDR PC3200
Win 2k pro
430W power source

GeForce FX 5900 XT (AGP)
and
GeForce FX 5500 (PCI)


I'm actually trying to run 4 monitors... 2 connected to each card. =) why? cuz I'm bored.

I'm trying to get these two vid cards to work together. I have both vid cards installed properly (far as I know). Each will work seperately. If I take out the AGP card, windoze will boot normally on the PCI card. If I remove the PCI card, windoze will boot normally on the AGP card. HOWEVER... win will freeze on the white screen with the win symbol and the little blue progress bar if BOTH are in the comp at the same time.

I have the nView extensions already installed (was running 2 monitors off the AGP card already).

I've had 2 vid cards in this comp before... an older AGP GeForce 4 and a PCI GeForce 3... so I know it CAN do it... I just don't know what the conflict is this time.

Also, I know some comps have issues with dual vid cards if one is PCI and PCI isn't set in the BIOS as the primary card... so I have it set that way (PCI as primary device).

Could the problem be:
the OS?
hardware limitations of the mobo/cpu?
Power? (I know these suckers draw a lot of juice)

Thanks for any help. This one has me stumped.

This may be it.

What company made your PSU? And how many Ampers are running thru the +12V rail (located on the side of the PSU)?
