[QUOTE="chscag, post: 1861868, member: 46727"] Very detailed bit of troubleshooting. I would have thought also that the power supply was the source of the problem. That leaves the GPU and logic board itself as the possible culprit. That particular model iMac has had some history of having a failing or failed GPU which shuts it down. I'm not sure how you can test for that without swapping out the GPU daughter board for another. By the way, that board is on the backside of the logic board and requires removal of the logic board. There are plenty of YouTube videos which show how to remove and repair the GPU. I found several with a quick Google Search. However, if this is a production machine that you need for work, you might want to forego all that and replace the iMac with a later model. I used to own that same machine and gave it to my son when I purchased a later model. He's still using it without any problems. (So far.) [/QUOTE]
