Black Screen With Sound

[intexity]

Here is my setup
q6600 c2q with GO stepping
EVGA gtx260 gpu
2 gigs 1066 ram
p6n msi mobo
850 watt psu
Windows 7 Ultimate 64 bit OS

installed the game and all i get is a black screen with sound. no video at all whatsoever and no crash. had a message pop up for windows live but fixed that and still no go. have been tearing my hair out and am one step from calling the company and demanding a refund. updated directx and nvidia driver (195 if i remember right) ran as administrator, applied the 1.1 patch, so on and so on. nothing works. please help.
