Need help - can't boot up my ibook G3. Any help would be greatly appreciated.  

Hello, I am having a problem booting up my Ibook G3 with Tiger OS X 10.4.11. The problem started when my ac adapter blew a fuse and I let my battery die completely (but it continued working after the ac adapter fuse blew). I bought a new ac adapter and the battery has been fully charged, but since the battery died originally, I have not been able to boot up. It stays on the grey screen with the Apple and the loading wheel. I reset the PMU and the PRAM and had no luck. I've restarted several times. I am hoping that I do not need the CD that came with the computer because I bought it second-hand and don't have it.

The last two lines just continue repeating. I am thinking that there might be a corrupted file but I have no idea how to go about figuring that out. I honestly have no idea what it means. There is only one user login for my computer (G3).
