Running the Macbook6,1 with Yosemite installed. I have my macbook set up so that when it powers on, it automatically logs into my account. When I boot up my macbook, it goes to the log in window and shows my desktop background all blurred (like it is meant to) and attempts to log me in. After that, the screen just goes black and my cursor remains on screen.

Boot into the recovery mode (CMD+R) and in Disk Utility repair both the disk and the disk permissions. Once done, restart the computer and see if it works properly again. :)
