I apologize for taking so long to update on what the issue was that had been causing such difficulties but I wanted to at least put this here since I had said I would. So long story short after having gotten some advice on what to do I tried doing another memtest and dxdiag. Neither showed anything out of the ordinary so with repeated problems continually popping up I sent my computer in under warranty. I got it back a week later saying everything was working fine and that no issues were present (No hardware issues at least). Right around the time I got it back a new AMD driver update come out and after installing it the issue seemed to clear up. I can now record footage and do video editing without any problems.
The rub is that now flash videos crash my desktop by giving me a white screen. I looked around and have come to the conclusion that the drivers out for the 7000 series of Radeon HD cards are unstable. End result, I'm buying a new card, an Nvidia lol.
Thanks though to those that gave me advice.
