Ok....every once in a while...probably once a day, my Dualie G5 2ghz freezes, and a grey shade falls down over the monitor with a "you need to restart..." message in the middle of the screen. If a CD is playing, that immediately starts to skip on the note it was on when the crash happened. Of course, I have tried to ID when all of this happens, but it is completely random. ANy ideas...I know...I know...needle in the haystack. Thanks for any info, though.
