Well, I was in OS X and everything was working alright except the superdrive. It wasn't reading any discs. So I decided to shut down the computer and turn it on (I used shut down and not restart). It froze on the desktop background for a few minutes, so I just held down the power button thinking that it would turn off. That did the job. Now whenever I try to boot the computer, I get the chime and apple logo, then I get a box that tells me in four languages that my computer needs to be restarted and that I should hold down the power button... So I do that and the same thing happens when I turn it on again. I've tried everything...resetting the PRAM, restoring the factory settings by taking out the battery, and just about everything else. Is it possible for me to fix this or does it need service? It certianly doesn't seem normal. The disc drive was working earlier today as well. Thanks PS, in case you didn't see my thread earlier today, my battery was not reading properly. It said that I had -1mAh capacity and the age was like 24,000 months. I don't know if this would be a part of the problem, but I figured that I might as well include it.
