I had the exact same problem with my brand new PC, I’ve updated everything (drivers, bios) run all test on my hardware everything’s fine, I have a GTX 660, i5 2500K, 16Gb memory…
I have change some setting in the game, and finaly solved my problem by reducing the sound quality, I dont know is its a coincidence but since I’ve reduce sound quality to the lowest setting I’ve never crashed again…
