I have an Intel iMac G5 24”. I purchased it nearly 3 years ago. It has always been disappointingly slow, especially when working with Adobe CS but in the past few weeks, almost everything I ask it to do results in the spinning beach ball of death. Now it has started having all kinds of display problems, ghosting, horizontal lines, sections chopped out of screen and sometimes widgets become just a mass of Technicolor lines. I don't even know where to start with this. I would just buy a new one but I am afraid the problem would follow when I transferred over all the content from the old one. I'd appreciate any direction.
