IBook G4 Goes to Blue Screen at Startup

Question

Hi,
My iBook G4, which is over 2 years old, won't startup to my hard drive. When I start it up, I can get to the grey apple with the loading circle, and everything seems normal. Then it goes to the blue screen where it usually begins to load my operating system (Tiger OS X), except it just stalls at the blue screen.
I have tried the following fixes:
1.Starting in Safe Mode (holding down "Shift" at startup): the computer takes longer (a few minutes) at the grey apple screen with the loading circle, but then it goes to the blue screen.
2.Booting from my OS install disk (inserting disk and holding "C" at startup): no change in behavior.
3.Resetting PRAM: no change in behavior.
I have had to do a hard shut down ten times now because it just blanks at this blue screen.
Other details: Before it stopped starting up, I had been running out of hard drive space. The computer also was freezing on me as I worked in applications.
Any help would be very much appreciated. I would love to be able to save my hard drive, as much of it is not backed up (and yes, now I know the dangers of not backing up).
Thank you, David

I too am having the same problem, Blue Screen freeze at start up. My symptoms, and attempted repairs are identical, except I don't get to view the desktop at all after fsck -y, it just reboots and stalls at the blue screen. The one difference is that prior to trying to repair with fsck -y, the iBook would boot and when it stalled instead of the blue screen I would get a strobe like effect from the screen. After Fsck -y, I didn't get the flashing again.
