Hi all, First post here, so much information. I have a iMac G5 for about 9 months now. Having persistent problems in that it keeps crashing on me, well it a black screen comes down telling me that I need to re-start my computer. Today its happened 3 times! We spoke with the 'desk' and they said it must be software and to remove everything from the Mac and re-install. Before we do this has this happened to anyone else? I deal with graphics and animation and its starting to really get on my goat. Feel so let down? Am I doing something wrong or is it my Mac. Any takers? Many thanks in advance! Buzby PS. It has been doing this more a less since I got it.
