iBook G4 won't go past apple / spokes

[Cybertron4000]

Hi there I did do some searching of the forum, and have not found an answer yet

I have an iBook G4, 930 mHz, gig of ram running 10.4.11

A jerk dropped my mactop while it was running. Now I does not go past the grey apple screen and the spokes just keep on turnin.

I used the hardware checker disk, said no hardware problems

I used disk utility, but don't really know what I'm doing there (booting from Install disk)

My drive mounts (at least I see it listed)

With Disk utility open, I go to file > "open disk image" I see all my files there (only greyed out)

I hope I"m providing enough info.

thanks for any help. I think I might have to get the data of this drive, and get a new drive

or what other things can happen when people drop a your laptop?
