problems with wow

[madhatR]

when i used to play before i could alt tab out easily with no problems .. since i went sli and dual core .. when i go to alt tab out .. the game stays on the screen and just flickers .. then when i alt tab again .. the game is fine ? i dont get it ..


also every now and then when i hearthstone .. it will just freeze for like 3 min then sometimes go thru .. or other times restart my pc ?
