To start off I've got a 12" Powerbook G4. 1.5 GHz, 768MB RAM. At the time of the crash, it was running OS X 10.6.11 (Tiger). I haven't installed anything or added any hardware to it in years. I was hanging out one day watching a movie through iTunes and all of the sudden the computer died. It looked like I had held down the power button to force-shut down. Current status: When I boot it regularly, it gives me the boot sound and shows the Apple logo and the spinning icon. Then I get the following error message: "You need to restart your computer. Hold down the Power button for several seconds, or press the Restart button." It says that in French, German and Japanese as well. It's got a blue background with a power icon in the middle. Oddly enough, it seems to boot just fine through Safe Mode and booting from the DVD (my original Tiger install DVD). What I've tried: Resetting the PRAM Resetting the PMU Verifying and repairing the disk while booting from DVD (disk was verified and repaired with no errors) Archive/installing OS X 10.4 Wipe/installing OS X 10.4 Any ideas?
