What can be done when Finder crashes constantly? Finder has started to crash constantly such that I can't click the icon in Dock. I can't click Apple in top-left corner of the screan (Finder also crash), I don't have any menubar icons from Apple like a Time Machine, Spotlight and the system is unstable. Safari crashes but what is confusing Google Chrome, Sparrow and other 3rd party apps works as normal. Only Apple menubar app that is working is Notification Center.

I tryied to start with safe mode but it failed to launch. I have turned verbose launch screen on before (it look more cool) so now I can see few error messages on start and after that information that my Mac passes some tests for a brief moment. Login in looks and works normal.

What is possible source of problem and how do I can fix that?

I have MacBook Pro Late 2011 with Mac OS Mountain Lion 10.8.2.
Only solution was complete clean reinstall of the system.
