I'm looking for some help. Yesterday I started experiencing a problem where my computer would lock up while playing Battlefield: Bad Company 2 (BFBC2). This doesn't happen while playing anything else like WoW, League of Legends and Starcraft 2. I run everything on max settings including BFBC2 and haven't ever experienced this problem before on BFBC2 (I've owned it about 3 weeks). The only thing that I can think would've made any difference yesterday is that I was inside my computer cleaning dust out of the filters and fans and whatnot and might've done something then? My temps on my processor and video card seem to be fine unless the reported temps are wrong.
