Random crashing

[Cat With A Mustache]

I re installed my steam and gmod and such since they were being a bitch. However, now GMOD randomly crashes on me, wither it be on the main menu screen, or joining another server. I've never had this problem before, and it's very irritating. Can someone please help me fix this, really in the mood for OCRP2.

Edit: Oh yea, when it does crash, my steam also resets, and no dialogue boxes open up.

Happens to me when I get new addons that don't work but, it could be an entirely different thing causing it.
