OK so here's the deal; I've got a G4 iBook purchased last August with a one-year guarantee. When it starts-up you hear the chime and after a few seconds the screen snaps into life as a blank white screen. Then nothing for around a minute then some weired muzak starts playing. It sounds like some crappy disney tune on a loop of around 30secs. as if it were a DVD menu screen background music. That's as much as the machine can be convinced to do. I've PRAM'd it and you can get the chimes two or three times but it makes no odds. It won't do anything different starting from an install disc (although it'll take the disc in and the drives spins it just gives up when the dreaded music kicks in. The only keys it'll recognise are the brightness, volume and eject. The disc will eject on start-up with the mouse button pressed and it'll only power down by holding the power button. I've even tried keyboard shortcuts but nothing. So question time; 1) WTF is going on? 2) Any ideas how to fix it? 3) If it has to be returned should I do it now and get it over with or be seaky and not return it until nearer August when (hopefully) all the G4 are used and they replace this (hopefully) terminal fault with a new MacBook???
