Counter Strike Source Loading problems.

[Zokoli]

Right, so when I go to load up Counter Strike Source it gets to the Loading... part then it just shuts down completely?
Some people have said on different forums it's the Steam Client patch?
How do I fix it?

I've played on this game before with the same specs, so I know fo' sure it's not them. :8

tried going to properties > verify game cache?
