I believe that I want to re install my OS (10.4) from the backup discs provided when I got my computer (G4 ibook 1.33ghz) Does this seem the best idea? I am worried about this because I have never attempted such a thing before with no assistance. I believe I have 10.3 on my backup discs and another disc to upgrade to 10.4. They are being mailed to me as we speak. I have decided this because 1. When I startup my machine I get the gray screen with the apple and then I can see the terminal running instead of the gray screen with the spinning wheel underneath. also, 2. in the last 3 weeks I have had to boot it up in safe mode to even boot at all. On top of these issues Safari has been randomly closing for no reason, at least once or twice a week I have that message, do you want to re open the application pop up all too often.
