I used to occasionally have the problem in the past where I start seeing the pink/black checkered boxes from missing textures or whatever, but they would fix themselves..... somehow. Well last night switching to 30 seconds on the Zombie Escape server, I started to see the black/pink checkered box for the "terrorist's win" pop-up when zombies won, and anytime I went underwater (the whole screen that would show anything underwater would actually be pink/black checkered). I wouldn't see it above water, only when my head went under, which was weird. I did some Googling and found that not having games caused the problem, but it was weird because I didn't uninstall/install anything from when the problem started. I have all of the Half Life's, Counter Strikes, etc. installed just in case, but I still get the problem. Could somebody shed some light on this for me if they have any idea what's going on?
