Question : Problem: Dual Graphics Cards :: 8800GTX & 5200FX - BSOD DRIVER_IRQL_NOT_LESS_OR_EQ<wbr />UAL

Recently decided to purchase a second graphics card to enable me to have more than 2 monitors. Installed it, booted, it posted, but as soon as it hits the login splash (Vista x64) it BSODs with the following errors:

DRIVER_IRQL_NOT_LESS_OR_EQUAL

BCCode: d1

The driver causing the issue is clearly the new graphics card and the filenames that have appeared during BSODs are:

"srv2.sys" and "nvlddmkm.sys"

I'm at a loss as what to do.
