So, whenever I open any of my Steam games, (Rust, Turbo Dismount, CIV 5, Dirty Bomb, Garry's Mod) I get a message that says "Oops! The game crashed. The crash report folder named "date and time" next to game executable…" It happens on everything but CIV 5 and G MOD, which just opens for a split second and then closes instantly. I have a Gateway FX-6801-03 with a core i7 920 @ 2.67 GHZ, 9 gb of DDR3 ram, a gtx 750 which I just installed. I just got this thing and I have been trying anything, someone please help!
