PowerBook G4 1.67 GHz not booting

My PowerBook G4 1.67 GHz is not booting. I did PMU reset and it didn't work.

Before this all happened it started to crash, the keyboard didn't work and

sometimes it freezed everything and a grey screen appeared saying that I should restart the machine.

I also did remove the battery for half an hour and same thing.

Don't know what else to do.

Thanks for any idea

iBook, Mac OS X (10.4.11), 1.33 GHz/ 1,25 GB RAM/ 320 GB HD/ 400 GB HD FW

The gray screen with the restart is called a kernel panic. Kernel panics are usually, but not always, caused by hardware, and mostly by memory issues. First step would be to reseat your memory (pull it out and put it back in).
