So recently, whenever I try to change my graphics to high in game to take screenshots(with my new monitor/tech), for some reason gmod crashes after going to a black screen for a minute or 2. It used to go to a black screen before, but then it would go back to my pause menu and I would X it out and take my screenshots. Now, it just crashes and exits gmod. As I said, it never did this before, and my PC is still the same otherwise, same settings, ect.
So, what can I do? I already defragged it and checked the cache(or whatever its called).
[EDIT] Screw you submission button, changing my HELP! to Games
