iBook G4 stuck in safe mode.

I have an iBook G4 and when I turned it on today, it loaded onto the login page where it had "safe mode" written in red.

I signed in but consequently I can not go on the Internet as it has disabled the airport.

I can't exit safe modefor some reason. I have restarted to noavail and tried to boot from the install discs but that fails.

It comes up with a grey page that says I need to restart and also has black blocks with white writing talking about debugging and stuff soi can't even use the install discs at the moment.

Any ideas, I am totally stuck. I am currently erasing the hard drive in disk utility and I hope that helps as it did when the hard drive was messed up before on my mothers iBook and I couldn't reinstall the software.

This is just a web browsing laptop for me but I can't even do that now so I'm really frustrated.

Thanks for your time and I hope I get some ideas on a solution.

Kindest regards,

David.
