trying to find a pattern here... Anyone with white screen blotches, please post your AlBook's serial number. MacBidouille's doing the same thing on their fora. As an example, the following G4 tower number:
CK140xxxNHD
CK: cork
1: 2001
40: 40th week of the year
xxx: ??? (no idea, anyone? a hardcore porno machine running OSeX?

)
NHD: Power Macintosh G4 (Mirrored Drive Doors)
Next thing would be to decipher and find out if the prob is from one specific time and space.
So? Theories, anyone?
