I've had L4D2 for years now and have logged over 280 of actual play hours into it with no gameplay/graphics/etc problems. But as of last year I encountered this bug that causes my game to crash after the loading screen. The screen goes black and whatever opening sound there is loops and repeats. I can't ctrl-alt-del out or alt-tab out, I have to reboot and it's even given me a bluescreen two times before. Has anyone encountered the same problem or does anyone know of a fix? I'm gonna try this fix I found here [server-admins.com] for a problem that seems similar to mine but I thought I'd post this to be doubly sure.
