My ipod crashed in the first 30 minutes of use but hasn't crashed after that in over a month. My Powerbook which I got recently and this is the first time I could actually work on it (because of the tremendous difficulty I had to get the hard drive upgraded because of real bad support and confusion of terms of warranty with their support people), crashed in the first 30 minutes and it crashed again as I write!! What must be wrong? Anybody? I put 2 gig of Kingston RAM (http://www.ec.kingston.com/ecom/configurator/partsinfo.asp?ktcpartno=KTA-PB533/1G).
