He then turns it on and he gets the white screen with the spinning loading sign but no apple logo. In place of that is a circle with a line through it. I try turning it on and I get the same thing. I continuesly shut it off and on and nothing works (not sure if this is good for the computer). I'm assuming when he shut it off the computer was doing something important, and now it won't even load the OS. Should I load the OS via CD? I'm not sure if the disks that came with it are the right disks, but I guess there's nothing else to do. Do I have any other options? I've had it for a year and never experienced anything like this.
