Hi, my powerbook g4 a few days ago display blue screen, I installed a fresh copy of osx, the install is done but at the boot after the gong the powerbook display a blue screen, only in security mode OSX run correctly. Yesterday searching on the web I found the commands for resetting pram and similar, but nothing works. At some point I pressed a combo of keys and the powerbook has restarted but the screen is always black and I hear the gong at the boot and the music at the first run of osx after the new installation. I don't remember the combo of keys that I pressed.
Anyone can help me?
Thanks a lot.
PowerBook, Mac OS X (10.4.11), G4 15" FW400 1,5GHz - 1GB RAM
