What do you mean about buying a new disk? You mean you want to buy a new hard drive for the iBook G3? In what way does freeze? Does it just beachball a lot, or does it actually freeze, meaning you have to reboot?
I've replaced the cable and everything works except the volume rocker? If I tighten everything and out the phone back together the volume seems to be stuck in a permanent down position. But if I open the phone back up and loosen the screws the volume doesn't work at all
