    I have the same problem. My iBook freezing also. I call my friend on phone, who has iBook, and he has the same problem... Now, I switch off my airport and it isn't freezing.

    This was the error report:

    Turns out there is quite a bit of this going around.  I'm dealing with it on a 1.42GHz iBook G4 model.  Most discussions are pointing to a failure in the connection between the airport module and the logic board.  Apparently it can become loose and cause the instabilities in the kernel driver.  Try turning off the airport and see if it resolves the issue.  That solution works for me, but I'd like my airport back so I'm working on a solution.

Have you gone into airport utility?
are you using an airport extreme? if so, reset it.
then delete the current wireless network, and try setting up a new one in airport utility.

I don't know the administrator password for my iBook G4

I don't know if this will help much, but you need to get your hands on a copy of either an iBook system disc or a retail Tiger OS disk. (Disclaimer: Please use legal copies.).

With the disc in the drive, restart the machine and hold down C to boot from the disc. There's an option to reset the admin password when booted from the disc. It may be in a menu (top of screen). Reset the admin password and you'll be all set. If you don't have a Tiger disc, you may be able to get one inexpensively from eBay or wherever.

This brings up something I've noticed helping people with problems, most don't know where their system discs are (or never got them). You'll likely need a system disc eventually. Friendly advice: Keep track of them!

During start up my ibook g4 freezes at the blue screen, which appears after the grey apple. why is that happening?

The blue screen marks the start of the login process. If the Mac freezes there, it usually indicates that some third-party System Preference is hanging the boot process. There are several ways to diagnose the problem. The simplest is to hold down the Shift key after hearing the boot chime. This will disable third-party System Preferences and should allow you to come up to the login screen. Then you can review the third-party preferences and go to the website of each of them to make sure you have the most up-to-date version that is compatible with your level of the Mac OS.

It looks like you have a hardware related problem. have you tried anything since? I would guess that the hard drive is dead. Tell me if I'm wrong!

Ibook G 4/12.1/1.33/5aptx.....will not start

Some computer react this way when the logic board goes bad or have a defect in it.  
First, Try this:  
Remove the battery.  Plug back in the power cord, then press and hold down the power button til you hear a loud beep sound. then release it.  If the computer starts back up... Then you should be okay.
If not, it may has something to do with the logic board.
Let me know if the above works... We may can try some other things if not.

Freezing is a HD problem. Do you hear clicking sometimes? Sometimes on boot up is there a foler with a questionmark in it? I would get your hard drive looked at, this is the reason disc utility fails. Your hard drive has a hiccup.

No luck

Probably the dvd drive is damaged (boot the computer with a bootable cd and see if it works, if not, change the drive), or it might have weak connection in it's slot, remove it and reinsert it in the laptop, see if it works.

Always freeze

Firefox will use a lot of disk space over time for temporary use. You might try starting up and run the Disk Utilities program to repair disk permissions.
