MacBook not booting or accepting disks.

My MacBook is not starting up. It emits a 'whirring' noise on startup and gets as far as the White screen before telling me to restart. The disk drive will also not accept any disks and I tried to install a Leopard install DVD after this problem started but that got stuck in the drive. Furthermore I have tried all of the startup options I could think of. Is there anyway I would be able to fix this or would the best bet be to send it off to get repaired.

Thanks,
