Gmod Crashing to desktop.

Basically, after a random amount of time (sometimes seconds, sometimes minutes) my game crashes straight to the desktop with no error message or anything. This is usually a few seconds or minutes after joining a server. The mdmp says: “The thread tried to read from or write to a virtual address for which it does not have the appropriate access.” I have already verified integrity and reinstalled after that didn’t work, all to no avail. Any help would be greatly appreciated, thanks in advanced.

Update your drivers for your graphics card and anything else.
Also make sure you have the latest windows updates too.
