I was watching a movie on my computer, and my macbook froze up. I held down the power button and turned it off. Then, turned it back on and it was stuck on the Apple logo and spinner. Fans were getting loud, nothing was happening after about 3 minutes so I turned it off. Now, every time that I boot up, it has a gray screen for about 2 seconds, the apple logo shows up for another two, then, as soon as that little gray spinner shows up the computer turns off. I have reset the power management, reset the pram, tried with out the battery, tried with only the battery, and am still **** out of luck. Anybody know what I should do before I take the computer and throw it at a geniuses face at the apple store? I have a god damn paper to write.
