My MacBook is taking forever to boot and then shuts off?

Posted at: 2014-06-09 
My 2012 macbookpro running maverick is taking forever to load and then when it gets to the next screen it just shuts off.. What could be the problem, and is there anything I can do to fix it temporarily so I can back up my information?
But I thought Macs were perfect, and never fail? LMFAO.
