Post init system start up freeze!

Well I got Windows 7 and everything was going fine until I downloaded one thing and at start up I kept getting froze on the Post init System part. So I force exited the game and delete my garrysmod folder. I played it and new folders came back so I downloaded 3 things: real dismemberment mod, Half-Life Renaissance v1.2, and PHX3. When I start Gmod up again I got the same problem. I do not have a pirated version I got it straight from steam. Would there be an easy solution to this?

Its happening to me too :frowning:
