A rather gorgous collegue of mine has asked me to look at her iBook for her. It wasn't booting, and just came up with a blank grey screen, kinda like the initial startup screen with the apple logo in the centre. It would just sit at this screen until it was turned off. I managed to get all the data off through FW mode, but still couldn't get it boot. I tired everything, and finally managed to get it to boot using Open Firmware and typing 'boot'. It booted up fine and i reinstalled Tiger, installed all the updates and restarted a couple of times, everything was fine. I moved all her files back through FW and restarted her iBook to make sure everything was set up properly.... but it starts up with that same grey screen again. Could it be a hardware problem or maybe a corrupt file of hers? I only copied over music/photos, though i noticed she had a lot of P2P apps on there...any ideas?
