Powerbook G4

Hi everyone,

my powerbook g4 is stuck! I try to reboot and it makes the chime but goes no further. I just hear whirring. I tried to start it up with the start up disc, but now that is stuck inside and I can't get it out.

I have been looking at all the questions and answers forum. I have tried 'command-control and holding down o &f. Nothing? I get the chime but nothing else.

I have also tried rebooting holding down eject button and also I have tried rebooting holding down F12 button.

Any advice would really be appreciated,

Aid
