[Q]: I was installing these chips in a G4 Sawtooth macintosh computer and the chips did not work. I had kernel panics that eventually left the operating system unusable. The hard drive had to be reformatted and the OS re-installed. A great headache and PITA. I need to return these memory modules, how would I do that.best regards,vilppu
[A]: Negative


[Q]: I Have had trouble with HP and XP since upgrading. Although they say it is xp compatable with driver, it is not. Will cause system to lock up and when I called HP they blamed XP. Bought a Epson and first time install without a hitch. Hope this helps and God bless you!
[A]: Negative


[Q]: A delightfully funny story! A wonderful graphic novel that gives us a cat's-eye view of the Sephardic Jewish community in Algeria and then the Algerian community in Paris in the early 20th Century. It's a love story. Very funny and endearing. And the hero is a cat! This is a must for Joann Sfar fans.
