Hi everyone, I hope I can get some help for a bizarre problem I'm having with my iBook G4 (1.2ghz). When I first got the machine (2004) I put in a 256mb Crucial stick and never had a problem. Recently (last 2 months?) I've noticed that a big slowdown so on a whim I checked my "About this Mac" and sure enough it only lists the stock 256mb. Is it possible for the added RAM to have just plopped out? Something else going on? Thanks!
