Garry's Mod crashes when any map is loaded.

Simple, I start up Garry’s Mod, and I choose any map. The screen turns into the “loading resources” and whatnot, then closes and says
“hl2.exe is not responding”
No idea why, I haven’t installed any addons in the past week, so I have no clue. Should I just resort to deleting the folder and re-downloading all my addons or is anyone having the same problem that Garry should fix?

Try moving your steam apps folder and renaming it. That’s what my friends ticket response said when GMOD was doing this.

clean Gmod
