Hey guys. Been having an issue recently with games randomly causing my system to BSOD and then reboot itself. It only happens during certain games (TF2, Rusty Hearts and most recently Dungeon Defenders) and with some (Namely TF2) simply taking the graphics settings down to minimum fixes it or at least postpones the issue for a while. I have a nVidia GeForce GT 240 graphics card and 3 gigs of ram, so none of this games should have any problem at all running at max and before I had to do a clean reformat, they didn't. It's not like I'm trying to run Skyrim or BF3 or something. I have updated all my drivers, checked for problems with diagnostic tools and even done a disk clean and defrag just to make sure, but still no good. I am running Windows 7 home with Service pack 1 installed and have included some of the most recent dumps from Dungeon Defenders crashes. Any help of further advice on how to go about this would be great. EDIT: I should also add, I can do ANYTHING else on this computer without it randomly crashing, it only happens when playing games. I can spend hours watching youtube videos or playing flash/java games and no problems at all. Only happens during gameplay.
