After the starting sound, it get stucked in a dark screen w/noise
One day, my old but nice iBookG4 won't start anymore. After the classical "start sound", it gets stuck with a dark grey screen, making a soft strange noise, like something is trying to start, but can't reach it.
here is a link of the little noise it makes:

Hope someone can help me on this.
