Help: Blue screen of death after adding 2nd video card

[mizzles]

Hello, I'm new here

Dell and NVDIA support both can't help, don't know where else to turn. I have a new dell XPS system with plenty of memory and HD space. I have 2 monitors attached to a NVIDIA GeForce GF7600GT card in the PCI express slot, my goal is to add a 3rd monitor. I was told to do so I could add a 2nd video card into the PCI slot.

When I inserted the 2nd card (GF5500), on booting windows initially started normally, detected new hardware, and automatically installed the drivers and asked me to reboot. Upon rebooting after seeing the windows logo screen I got the blue screen telling me windows had been shut down to prevent damage to my computer. I had to do a system restore to the previous day in safe mode to get it to work normally.

Microsoft "crash analysis" states "A device driver installed on your computer caused the problem, we cannot determine the precise cause" I'm guessing it was caused by the driver for the new video card or some hardware incompatibility.

Does anyone have any ideas to help me here, I'm hesitant to put the card back in again.

Thanks

Miz

He is referring to the size and make of the Power Supply
You could also try uninstalling the Default windows driver
for the new Video Card, reboot & when windows redetects
the card, point the Wizard to the real Nvidia Drivers that
should be on a cd provided with the card
