Multiple and frequent crashes

[wee wee whipper]

When I play left for dead 2 it usually is fine through any campaign, but sometimes I will do an action then the game stops. That is rare but whenever I finish a campaign typically It will show the end animation, say The survivors have escaped!, and then it crashes

Maybe you need a better pc, i remember had this problem on an older computer. Probably the memory overloaded and it crash the game.
