This is interesting. I had a friend ask me to look at her computer with the same problem reported here. I replaced the hard drive, reinstalled OSX 10.5 and all was well. I ran the software update, which downloaded 10.5.8 combo update. After the update installed, the computer failed to boot again. Is it possible a recent update could have hosed the system. Mine is an iBook A1054. I'm currently re-installing the OS again. We'll see what happens.
