Forum:Constant crashes with DLC3 (PC)

anyone else experiencing this? it seems to happen when those missiles get launched from the mountains and the ninja-like enemies teleport out of them. it kept happening on the first one so i recopied the expansion over and that fixed it. now it happens with the second one before i can get to moxxie.. it also happened when i tried to jump out of the monster-car as it blew upnear moxxie's place. the thing is, it reboots my pc.. not just the game. ive recently installed the new nvidia drivers for my card as it was required to play the new AvP game

any ideas? besides reinstalling the game and all DLC..
