Bsod/Freeze at login. Mixed GPU.

[Draex]

Having an issue with a mixed GPU folding system I put together today, I tested all the components independently and run fine. The system runs fine at first when using the microsoft WDM or vesa drivers, but after installing the nvidia drivers 195.X, or attempting to change the resolution on either screen the system BSOD's complaining about nvlddmkm.sys, on subsequent reboots the system will hard lock on login to windows 7, until I go into safe mode and remove the displayer driver. If I remove either card the system runs / folds fine....

System spec.

Windows 7 Prof.
Abit AW9D-Max
intel e8400
2x1 GB OCZ-PC6400
OEM GTX 280
Asus EN8800GT
Corsair TX-750
Lots of random Hard-drives.
2 17inch junker CRT's

Install is fresh.

I pulled the 8800GT again, and well doing so have noticed that cards are unusually hot, touching the plastic housing around the fan/heatsink assembly was more then enough to burn my fingers. Yet both fans were running.

Turns out this was a bad Corsair TX750.

Actually I think its bad drivers.

There are many people having issues with the 191.xx and above drivers on both win7 and XP.

I run a 260 and an 8800GTX , both the 191 and 195 driver sets cause my 260 to fail.
