ibok G4 - freezing

kolac

Registered
Hi all, I am asking for a piece of advice.


Issue: ibook G4/1,2GHz, 12", 1,2 Gb ram, 40 gb hdd ( replaced ), airport card extreme

after exchange of the HDD is finally able to boot,

usually freezes on blue screen after apple logo has come out and rotating sign vanished

sometimes boots normally and I can work on it for some time, and then freezes ( freezing = sometimes I can move with mouse, but everything else is frozen, sometimes it is like a picture on screen, no move )

I don t know whether it might be caused by the moving of computer (sometimes it freezes when i move it, but sometimes i can carry it from one place to another and it is ok)


I have replaced HDD. regardless if the 1GB RAM modul is in it or out, it behaves the same

I wonder whether it might be caused by power supply, as I charge it by ibook g3 power supply and I use the g3 battery as well


What are your suggestions? Please, give me some advice, I am really at my wits´ end. :(
