Hey there! I had the game installed since 08/30 or 08/31, either or >< And just recently within the last 3 days, I’ve been experiencing the same problem. I would be playing for actually about 45 min myself and then the screen goes black and i hear a “zzzzzzzztztztttztzzzzz” forcing me to do a hard restart of my system. My graphics card is Nvidia Geforce GTX 460 and my system is 64-bit. My driver (which my game client suggested i should install after i updated it to the most current “non-beta” driver) is the 304.79 beta. Any known issues with this driver?
