Re: Sart up Problem
If it's stuck on the gray screen with the progress bar and spinning sprocket at the bottom, it's running a file system check... If Searay's suggestion of zapping the PRAM (Apple, Option, P, R) doesn't get it going again, try rebooting in verbose mode (Apple, V). This will make your computer show you in words what it's doing, and most importantly, if you keep getting a repeating line or set of lines, you'll see what/where the problem is. Most of the information verbose mode shows probably won't make much sense, the important thing is to watch for a repeating line or set of lines where it's stuck doing something, and if it does, write down whatever's being repeated and let us know.
