Suddenly my mac book pro will not turn off.  first it started with the computer cutting off rather than going to sleeep then it started cutting off while I was using it.  I became worried that there was a problem and went to back up the hard drive on an external hard drive but suddenly the computer would not start at all.  before that happened i would get the gray screen with the dial and a bar underneath.  Help!

MacBook Pro, OS X Mountain Lion (10.8)
