Hello,
my powerbook G4 displays just a white screen and stops there...
Sometimes it displays the apple icon on againsg a white background and stops there..I have tried almost all the commands and combinations i have read but the problem persists upto now..
Please any one help me..am doing my research and all my data is there..Have no back up and am really confused..
Thanks.
