I can browse online for hours - no problem at all - computer is fine

However, I start playing any form of game or watch some video in 1080p, and I feel like my computer is playing Russian Roulette with the Blue Screen of Death.

Happens frequently and in the middle of Dota 2 / Witcher 2 games and it is driving me nuts. Basically any "intense" game that I am playing. Computer will BSOD and I will get the following message.
I decided let me try my luck tonight. First Dota game I start to play - computer gives me the BSOD 10 minutes into the game.

Again - any help here would be appreciative.

Thanks
