@RS13, Out of curiosity are you overclocking your game rig at all? I noticed in my vanilla game that my overclock was stable but the moment I added in just one mod...BAM , Crash to Desktop at seemingly random intervals ( lucky if I made it to an hour!) . Funny part is the only thing I had overclocked at the time was my system Ram and just by 33 MHz .....but it was enough to send Skyrim into total conniption!
