Garry's Mod CTD

Everytime I try to load Garry’s mod, its continuosly crashes to desktop. What can I try?

Post specs.

My PC is as follows:

AMD FX 8150 3.6GHz 8 Core CPU
16GB DDR3 Memory
1GB NVidia Geforce GTX 560 Ti
Creative Soundblaster X-Fi Sound Card

-dxlevel 80
no work?
-no vid
no work?

Tried all of them to no avail.

Is this… Gmod? Or Gmod13?

I’m stumped. Might have to wait for an update.
Tried verifying cache?

I’ve verified the cache, deleted it, renamed my steamapps folder so it looked like a new install, reinstalled it, then deleted steam and reinstalled that then did the same process repeatedly to no avail. I think it’s G-Mod, the one from steam.
