Garry's Mod Joining server

Everytime I try, to Join just one
server It crashes
How it happens is like I just start the loading
after i am loaded i see the disconnect in (red) numbers
and I also see (it seems you have crashed or map is chancing)

I tried serveral times, to re-install garry’s mod and even steam for it
My pc reset dindt work also

If you Can Help I would Like that.
