Problem is know from the beta.
Blizzard run game with knowledge that game is unoptimised and can cause hardware damage.
Vendors at beta caused bug with extreme power spikes / power consumption. Every time You talked to vendor Your hardware where attacked by power spike.
They did nothing and bug exist.
My laptop died due to it, i lost warranty half year ago so now i have to afford new one or wait for my pc that should come on next two weeks.
I will back to game if the problem will be solved. Game is awsome but not worth losing another PC.
