BSOD when playing certain games

[subsonicdust]

Hey, guys. It's my first post here on this forum, so forgive me if I miss some things out.

I bought my current PC in October 2011. For the most part it's a great system, but ever since I bought it I've been getting sporadic blue screens when playing certain games, particularly on demanding games like Battlefield 3, Skyrim, Metro 2033, and a few others. Some games run fine with no issues, but the three I've listed are the biggest culprits. I can play for indefinite periods when the screen will suddenly go black for several seconds and the system automatically reboots.

I replaced my old 500W PSU earlier today after hoping that a new, more powerful unit would fix the issue. Alas, it didn't.

My current system specs are:

Windows 7 Premium 64-bit
AMD Phenom II X4 955
AMD Radeon HD 6750
4 GB RAM
ASUS M5A78L-M/USB3 board
Corsair CMPSU-750TXV2UK 750W

I've included the two required zip files and the latest minidump file from a blue screen I had earlier today whilst playing Battlefield 3.

Any help on identifying the problem would be much appreciated.
