BSOD while playing BF3

Well I haven't had any BSODs in quite awhile. But after installing Battlefield 3 I'm starting to get them.
I reinstalled BF3 yesterday and still got them.

System Specs are;
Motherboard- Asus Crosshair IV Formula
CPU- AMD Phenom x4 955 BE @ 3.8Ghz
RAM- 4x2GB G.Skill Ripjaws DDR3 1600 (PC3 12800)
GPU- 2x AMD HD 6850 (Crossfire)
PSU- Cougar (Compucase) 850W

There have only been 2 actual BSODs. A few other times the screen just went black and the sound distorted until I restarted my PC.

Here's the minidump files. And help would be appreciated.

crash was caused by the directx portion of your video driver. I would re-install the newest version as indicated.
When upgrading your graphic driver you MUST remove all traces of the current driver
so update your graphic card driver and download and install direct x 11!
