I was on my PowerBook G4 Titanium, surfing the web perfectly fine last night. I woke up this morning, and it would get stuck in a startup loop. The little spinning gear would come up, spin around for about 5 minutes then restart. I'd also get the odd kernel panic. So I put the Tiger install disk in they drive to try and get the ting back on it's feet, but the installer keeps failing. So I tried installing Jaguar (grey disk) and the same thing happened. I'm a bit stumped on what to do here. Is it any good for parts or is there something I can do to get it working again? Thanks.
