Game starts freezing on and off after playing for about an hour Okay, so I go to play online, and everything is fine, until... After about an hour (though sometimes sooner) the game freezes up. Or more like, my computer does. During the freeze, which lasts around 20 seconds, I can't do anything. No alt+f4, no ctrl+alt+delete, nothing.. But after 20 seconds or so, the game will unfreeze for a few short seconds, then freeze up again for another 20 seconds. During this time I usually exit the game asap, but the freezes still continue. Yes- even when the game is not running, Windows continues to freeze on and off. In the end I have to reboot my computer. Anyone know what's going on??
