Different BSOD's

Starting late last night I was playing WoW, when I BSODd. It happened again after I restarted my computer and I have been getting numerous BSODs while doing random things on my PC since then. I'm pretty confident it has something to do with a driver, but I cannot identify which one or what to do. All my graphics drivers are up to date. I have posted on another forum and checked numerous threads, to no avail. Any help would be amazing and I would be immensly grateful, as it is difficult to game or do anything else on my computer without BSODing. Please let me know if any more info is required.

So, I installed 4 more gigs of ram a couple of months ago, so I took out my new ram and tried to replace it with the older ram, but still encountered a BSOD, albeit a new one. I put my new ram back in just now. Here's my updated minidumps.
