My MacBook Pro won't let me login
My MacBook Pro won't let me login. I have Yosemite. After I turn the computer on, it goes to the login screen. After I type in my password, a white bar appears underneath and slowly fills black. It reaches about halfway then the entire screen turns gray before going completely black and restarting. I've gone through this process a few times.
Prior to this, my screen went completely blue a few different times but I was able to restart with no problems. But now I can't get past the startup screen.
Anyone else have this problem?
MacBook, Mac OS X (10.6.8), Boot Camp 3.0.4
