My Mac account is completely blocked I recently had some problem with my account that I use on a regular basis.

After logging in, my Mac blocks completely showing the spinning color wheel everywhere I click to open something. Finally I need to restart my mac, because I'm not able to do anything. Now, the strange thing is that this does not happen when I log in into another account on my mac, then is everything working fine. 

Anyone that knows how an issue like this?

My mac is on Mac OS X Mavericks and is a Macbook Pro Mid-2010.
You could try to login in without starting login items and opening finder windows. You can do this by holding down the SHIFT key after you type your username and password at the login screen.

This will probably only solve simple problems with your login. More details are available here: http://support.apple.com/kb/PH14215
