Graphics Blue screen of death when installing graphics card

Just finished putting together a new system, installed the mobo drivers, but when I instal the drivers for my cards, halfway through the instalation the blue screen of death pops up
I tried first with the included XFX drivers, and then with newest version of ForceWare from the nVidia website.

Specs:
Windows Vista Ultimate 32bit
XFX 8800GT XXX in SLi
Asus Striker Extreme with Q6600 (CPU has a Thermalright Ultima 90I)
Patriot 2X1GB 800MHz DDR2 4-4-4-12
Corsair 620W PSU

What the screen o'death says:

DRIVER_IRQL_NOT_LESS_OR_EQUAL

and then:

*** STOP : 0x000000D1 blah blah


Nothin is OC'd, just finished putting the thing together. Got myself Crysis and cant try it out

 

hi,

don't have the right answer for you, but why don't you install just one card and then the drivers.
If that all works you can play you game, and might be able to install the other card and select sli mode from nvidia control panel.
