    I have used these computers before... check

    A) try restarting the computer, by turning the switch on the back off, then on, then press they keyboard power button

    B) It could be a dead PRam (clock) battery, look into replacing it...

    C) one of your ram dimms could have failed

    D) Chance that the analog board/power suppy are failing...

    Do the fans spin up, and does the front green light turn on?

    ok, if the fans spin up, but the front green light doesn't go on, its most likely some type of logic board issue... on those syle macs, the green light turns on only AFTER the system logic board issues the ok.. on other models, the light goes on as soon as you turn on the computer...

    I moved it twice, once from a hallway to a classroom, then left it in the classroom for a while, and then back to the hall again. When I moved it in to the classroom, no problem, i kept it there, no problem, i moved it out to the hall, and it now doesn't work. could it involve the fact that i moved it back to the hall? I don't think I hit anything.

    Not sometimes, just never. The thing just took a crap on us. It'll make the ding noise when it starts, the fans start runnin, and that's it. so really, that's all I can say.
