Alienware Blue Screen

Three months ago, I purchased an Alienware M11x R2. For a while, it worked just fine. Then, I started to have issues with gaming. It seems that if I do anything RAM-intensive, it crashes. The latest crash report:

I'm not quite sure what to do from here. Any help at all would be appreciated.
