Hi, folks!

Excuse my bad english. A friends old Powerbook G4 15` (last gen. before Intel-Hardware) has got a problem.

From one day to the other, it will not boot-up normally. It boots in a kind of "Bios", white letters on a

black screen, running in lines. Nothing more happens. It seems to hang in this "Bios"-like state.

Can you please help?


PowerBook, Mac OS X (10.4), Titanium, 1,67 ghz
