Macbook Pro wont start, but pretenfs like it is going to and then turns off
So, I opened a game, the Mac crashed and, won't turn back on. Itll turn on for a few seconds and play that loud noise and appear like it's functioning properly and the little bar fills up a tiny bit but then it turns back off and repeats if I prompt it...any help?
iPhone 4S, iOS 7.0.2, Year or so old.
