Hello,
I have a 15" PowerBook G4. Two days ago I upgraded the RAM by one GB and yesterday, I upgraded the OS to 10.5.0. The computer was working fine (all my old stuff was still there and in order), until last night when it looked for updates. There were six updates, one of which was presumable to upgrade OS to 10.5.8 (as it says I am there now). I downloaded the updates, and when I went to shut down for the night, it said it would finish updating and then shut down. In the morning, I turned on the computer and it took almost five minutes to boot up (most of those minutes spent at the blue screen). Now, if the computer goes into screen saver, it freezes, and can only be shut down by holding down the power. I also can't restart the computer. I thought re-installing OS might work, but it can't, as it will not restart correctly. At the prompt to restart to start the installation, I click restart and the computer freezes (screen black). I can hear movement, but can't wake it, only holding down the power button.
So, how can I fix problem, or reinstall OS X to at least get back to where it was working?
I have already tried taking the battery out and holding the power button down, filevault is not running, I have not set up the time-machine yet. I am assuming my problems are connected (boot-up and shut-down/sleep problems.
Thanks,
