If anyone can help, I'd appreciate it. I powered on my iMac 24 (purchased in 2008) the other day and the entire screen pixelated (reds and purples), then just froze. I cannot do anything. If and when it fixes itself, I can click a user but that is as far as I can go. I tried using a different outlet, which worked for about an hour. The above problem occurred again. My Apple warranty has expired. I am running all current, up-to-date software, no upgrades or anything special. Any clue as to what it could be would be a great help! Thanks in advance!
