[EX 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
[EX A]: Negative

[EX Q]: Phil Collins singing "Take Me Home" and Mark Knopfler performing "Brothers in Arms" and "Money for Nothing" are fantastic; heck, Elton, McCartney, Sting, Eric Clapton, Sting, Jimmy Buffett, Carl Perkins and Arrow are all great. This is a wonderful concert; I just wish I could have heard it in person.This DVD looks fantastic and sounds terrific--especially on a DTS capable system like mind. I buy music DVD's only if I can see that they have DTS encoding on the disk (Amazon please take note). However, in a few places--just a couple--the sound quality of "Music for Monserrat" falls down a wee bit compared to other music DVD's I have; otherwise, I would have rated it 5 stars.That said, this is a great DVD for those like me who love these artists.
[EX A]: Positive

[EX Q]: Well, it arrived on time and in OK condition, but after almost a month of taking it, I haven't noticed any change, except now I have stomach cramps.
