Alright, so this morning I woke up and I was going to play gmod when I waited for it to load for about 5 minutes, and then it closed and said hl2.exe has stopped working. I've turned my computer on and off but it hasn't changed a thing. I will try to un-install and re-install it but if that doesn't work, I trust you guys to give me good advice to help me.
