First off, my computer is a uMBP mid 2009 2.53 ghz model. I was watching a youtube video when all of a sudden a dark shade came down the screen and the audio skipped. Then the MBP froze up with a message that said something like "Restart your computer by pressing the power button. Turn it on by pressing the power button again." (something like that) Anyway, so I turned it off by the power button, turned it back on and I logged in using my username and password. The background loaded and the shade appeared again with the same message. Now when I restart my computer a loading bar appears below the Apple logo during startup and the computer just shuts off without allowing me to log in. I still have applecare but I don't have the technical support. I bought mine at the University bookstore. What should I do? And what do you think the problem is? Is there anyway to salvage my files?
