Sometimes when I am playing the game, and especially when I play the MP during and after I'm getting a full video whole PC freeze to crash. I've tried everything that I thought that I could do to resolve this issue, but nothing that I've done has worked as of yet, including voltage tweaks, Windows Services alterations to the video card or RAM Memory voltage adjustments or switching. I can seem to hold this issue off a little bit by upping the voltage on a third party GPU utility but it never fully fixes the issue. I am experiencing a full screen crash to reset of the entire system and again this happens especially during or even after I'm done playing the game. I am running the game with a Radeon HD 7970 - AMD graphics card. Help would be of the utmost appreciation because I really enjoy playing this game. It is one of the few games that I will even take the time to play anymore. Thank you in advance for any help on this matter!
