Hey! My macbook just shut down during a backup of its own accord, and now when i turn it on, i see a gray screen with nothing on it and it makes weird clicking/scratching noises from inside the computer. Also, I've tried turning it on 3 times, and the 2nd it made one long, ominous beep as it turned on, but on the 1st and 3rd tries it didn't. I'm so confused. Also I'm really scared, my computer cannot crash right now. Apple care is closed, so I thought I'd ask what's wrong with it here. Thanks for your help!
