For 6 times, in 8 attempts, my retina macbook pro fails to boot up. All goes black after I enter my user password and I have to press the power bottom for 3 sec to restart. It sounds like a system error, and for sure didn't happen before I installed mountain lion, should I attempt to do a fresh install? Or run any tests?

Any advice appreciated.


MacBook Pro (Retina, Mid 2012), OS X Mountain Lion
