ok ok, its not my video cable (i checked it) also my graphic card plays gw on xp, vista, mac os10, mac leopard linux. but not windows 7 lol. its not over heating and the screen doesn't go Black per say, its as if the back light turns off. i will try running gw in comparability mode and see if that helps, but from my own research i think windows 7 has a problem with some games so i might end up going to back to xp.
thanx for all the help so far, if anyone has had this problem also post and we can try and find a solution
