thanks for all the suggestions. After way too long down time, it turns out that the 512 RAM module I has added appears to be the culprit. Disk turned out to be fine, checked with SMARTD. Replacing the original 256 MB module restored stability.
I'm puzzled as the 512 module is a 512mb PC133 SO-DIMM CAS3 pulled from a iBook G3 (in which it works very well) and this is exactly the kind of RAM used by the PB G4 1GHz. It has also exactly the same labels on it as the original 256 sticks, it looks the same, same brand, except for being sligthly shorter in height. I'm not sure if this is to be considered 3rd party RAM? It has also worked with no problems since I installed it, just until all hell broke loose with the latest software updates. So the message here is for those attempting to up their RAM without being robbed by Apple: be very careful. I'm not sure whether it's the OS or the machine hardware responsible for this pickyness about RAM, either way it's highly irritanting (to me at least). cheers and thanks again for the help, gianfranco > I had a similar experience on an older PB about a month ago.
