I've been to tons of other sites for my problem and I can't find a solution. The kernel Power errors happen when ever I play a rather large game, such as Left 4 Dead, Left 4 Dead 2, Dead Rising 2, Assassins Creed Series, and Battlefield Bad Company 2. I've tried unplugging all my external devices such as, my headset, It worked for about two weeks, but then the errors started happening again. I had this computer custom built for gaming, It's not even a third full, And I want this to stop. I've updated all my drivers, Uninstalled tons of my games, just to get one working.
