Pbook G4 wont boot! 'unknown error: 0' shows while installing then Kernel P

Question

My powerbook decided not to respond anymore. I thought it could be a system error, something with system files, because i tried apple hardware test (quick and advanced) and everything was ok, the mac could even initiate with the cd installer, and i could read all drives with disk utility with all correct permissions and repairs. With another powerbook i used firewire connection and backup all files, and then made a 'erase and install' a new copy of Mac Os 10.3.7:
the problem is:
first time, it crashed in the middle of process with a kernel panic. i was frustrated
second try, the installation finished but it wont boot again: i booted with install cd and i saw in 'system passwords' that there was no user in the system at all!
last try: while installing i opened 'install log' and these where the sentences until it crashed -
Extracting files from (...)
Running task: /System/Library/PrivateFrameworks/(...)
Finished task: /System/Library/PrivateFrameworks/(...)
Extracting files from (...)
Running task: /System/Library/PrivateFrameworks/(...)
pax:
could not read compressed data
Unknown error: 0
Finished task:/System/Library/PrivateFrameworks/(..)
this was the error, it happened 3 times, in 3 distinct moments, until kernel panic appears.
simple question: what could it be? thank you
