My G5 was working perfectly until yesterday.  I have had 10 years of use but yesterday, I had a kernal panic and had to close down.  Now the system is very unstable; I can get some way along booting but no longer can boot.  This is what I have tried:


1) got a new 1TB hard drive

2) one time, I was able to re-intall Leopard from the retail disc.  I needed to reset the passwords.  I retireived data from time machine and it was back up and running.  I saved all documents etc to a falsh drive.  Phew.

3) the system then froze

4) using 'option', sometimes I can choose the dvd and go past the first language screen for re-install

5) once, I was able to open disk utility and the new HDD is ok according to 'repair'

6) the system always freezes whilst I am in disk utility after a few minutes

7) safe (shift) boot never works, sometimes, I have a blank screen, sometimes the grey screen but no turning gear

8) I cannot reset the PRAM.  After the chimes, I hold command option, P R but never get the second chime (5 minutes)

9) I have replaced the PRAM battery @ $17.00 (it was 10 years old)



Summary: booting from new HDD just gives me the grey apple screen and no turning gear (eventually, the fans start to spin faster and faster).  The LED by the on button is solid white.  Sometimes I can get boot from the Leopard DVD but the system freezes.


Any thoughts?




G5, Mac OS X (10.4.11)
