Hi, I'm having a problem with my iBook G3 (yes, I know it's old, but it still gets the job done. ) What happens is, it can turn on and get past the "Starting Mac OS X" screen and all, but after that, it goes to a command prompt screen. I'm sure that I didn't activate any keyboard shortcuts when I turned the computer on. And after that, I'm presented with a blank blue screen. I can even leave the computer on for hours and still, nothing will come up. I've checked to see if there was anything wrong with the hard drive, but fsck always comes back with "The volume appears to be OK." I really don't know what to do... Any ideas?
