Unexpected repeated ibook crashes

[Jason_Bryan]

My iBook g4 has started to producing a grayed out screen and a message saying I need to hold down the power button to restart. I have all my documents backed up so the first thing I did was a clean install of Leopard. That has not stopped the problem. I have copied the info from the log the computer would like to send to Apple. Can anyone tell me what it means?

Run disk utility from the install CD and check / repair the harddrive. That may do the trick. If it can't be repaired, you'll need to replace it.

Kernel panics may be one of several issues. Go here for a free guide on ibook problems and things to try to solve them.

Well, it starts with the hard drive interface, then moves onto the AirPort card.

Been inside the iBook there fiddling? Replacing hard drives?

 

[Jason_Bryan]

I have not changed the hard drive or airport card
