Which memory stick do you have problem with? One you got from OWC, or the later one?? My memory problem on PBG4 was the faulty logic board. It was replaced - twice - under warranty. But its screen is going haywire occasionally as soon as I turn it on. Will stabilize several minutes later (as the graphic card warms up, I guess). Koichi Yasutani - a.k.a.
