Freezing & Crashing

Hello, I have this problem with some servers where I would join and load all the materials/models. When it gets to the end, it freezes. I’ve left it for a long time 1-2 hours and it is frozen. I have to CTRL+ALT+DELETE and end the program. Also, when I try to play a map in singleplayer, it just goes to desktop and the gmod taskbar icon disappears. Could I have some help?

Go to your GMod root folder (steamapps/common/GarrysMod) and look and see if there are any .mdmp files. If yes, put them here:

Okay, I have it here.
