I bought a new Power Mac G4 about 3-4 months ago. The thing freezes completely solid all the time, Sometimes 15 times or more a day. It does it with all apps, or sometimes with no apps open at all. They have replaced the RAM and the logic bord and it still happens. It is out being fixed, so I have to use an old Power Mac 7200/120 for now Does someone know what I should do? The people at the Service Provider who are fixing it are pretty clueless.
