First, which model? Which specs? (model year, CPU speed, Ram quantity, graphic card, OS version...) IMO, every time we talk about problems (especially hardware ones), we should first state our computer configuration - it gives a much better context for understanding what's going on. First thing off the top of my head, is the graphic card. I read several iMacs (usually the ones with more powerful cards) suffered from issues like freezes, crashes, screen artifacts. Then, overheating: - can an iMac get dust inside? If yes, accumulated dust could impede cooling; - maybe the CPU (or something else, like the GPU) lost "contact" with its cooler; in this case, cleaning it and re-applying thermal paste is usually enough. Lastly, I think the screen has nothing to do with your problem. It sounds like overheating, most likely. -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.
