ok i am almost ready to give up and ask steam for a refund as i keep getting a BSOD error 124 within 1 to 10 mins of playing the game:

specs:
win 7 64bit ultimate
amd phenom ii 945 3ghz
8gb corsair ram
nvidia geforce gtx 550 ti
sound is via the video cards hdmi connection with built in sound card disabled

tried:
updated os
updated all drivers including bios
stress tests on CPU, GPU and RAM with no errors found

anyone got any ideas? no issue with any of the latest games on full settings!
