In any case... I need a solution that doesn't involve moving to Alaska.
Hahaha! Nicely put.
Perhaps so... it's summer now, and warm. Not so much so in previous months. I suppose this contributes to the problem, but would it be the only cause?
If it is not too much warmer & if the room temperature is controlled, it shouldn't be enough to cause such frequent shutdown. Perhaps the fan of the gpu died. The fan's under will not help if the internal fan is not spinning in the first place. Do you hear louder whirring sound when you game (indication that fan is spinning faster)?
By the way, I notice your name "Madwand". Are you by any chance a fan of Roger Zelazny?
