Restoring OS 10.4.11 from a 10.4 start up disc
I have an older G4 running 10.4.11 and need to either re-install 10.4 or try to restore the system. It won't shut down, sleep or give me access to internal discs. I have to force shut down the system every time I click on an internal disc. I've run Disk Utility and it says the discs are fine. I ordered DiskWarrior and have not received it yet and was going to go this route before it arrives. Any suggestions would be very helpful. Thanks
