	My Powerbook G4 (400mhz) has two major problems: 1) It freezes during boot or shortly after booting. 2) Sometimes after I power on or reboot, the screen NEVER lights up and stays completely black. Sometimes, it does light up, but see problem #1. Details: Just installed OS X 10.2 on it, but it crashed right after it finished installation, after selecting the US keyboard settings. Now it freezes with a blue desktop background and the mouse pointer in the upper left corner. Is this possibly a hardware problem? (Last edited by examplify2006; Aug 14, 2006 at 05:28 PM. )
