Garry's Mod is crashing!

Hello.
I’m having some problems, My Garry 's mod client is crashing a lot
Whenever I’m playing any game-mode
Tried deleting some Addons
And verifying the game cache but nothing is working.
If any one who had experienced same problem and fixed it, Please help me fix this.

** I have uploaded my Crash Dumps which existed on my Garry’s Mod directory :**

Has it worked in the past and just recently started? If not it might just be a matter of your computer.

It used to be working perfectly.
It just recently started like from a month…
Other games are working perfecly
