I have a first gen black MacBook, and I was using it at school yesterday just doing some work in iWork, and then got a kernel panic. Fine, no big deal, so I turned off the computer and turned it back on, but it hung at the gray screen with the apple logo on it for a long while, and never went past it. After I got home last night, I tried starting it up again, and it did the same thing, but after staying on the apple logo for a little bit, the logo changed into the symbol that has a circle with a slash through it (I don't know what it's actually called). I wasn't sure if that meant that it couldn't find the hard drive or something, but that was my assumption. I didn't hear any weird HDD scratching noises, which I suppose is good. I put in my Leopard disc so I could boot from it and see if I could figure out if there was something up with the hard drive. However, when I tried to boot from the disc, the disc kept spinning, but the logo/circle-slash symbol just stayed on the screen, and the MacBook never booted. In addition to that, all of a sudden, sometimes the MacBook won't turn on when I press the power button. The little light on the front of it will turn on, but there's no startup chime, and the screen doesn't appear to turn on. I'm kinda stuck...has anybody seen this before? I'm guessing I'm going to end up having to go to one of the Apple Stores around here over the weekend, but if anybody has any insight, that would be great.
