My iMac G5 is having major screen issues. After some reading around the web, especially in this MacRumors forum, it seems that I'm having a graphics chip issue. My screen looks similar to the photos shown in that thread (I can't post a picture here). I don't think it is a problem with the display, because if I do a Screen capture and then open that image on another Mac, the image is still distorted. Right now I am backing up all my data, and then I will attempt safe mode. If Safe Mode causes the machine to operate, is it possible to operate in Safe Mode all the time? What would the side effects be?
