My 5K iMac keeps turning off while I'm using it?
So around the two year mark I beginning to have a problem where my iMac it keeps turning off on me.
I'm currently running El Capitan on it and after 3 visits to Apple Store they have failed to fix my iMac and replicate the problem. The issue with it is that it turns off after several months or even after a few days. I never not know when it's going to turn off and I confirmed that has nothing to do with anything I've installed or with the programs I run.
The people at the Apple Store suggested that I replace the logic board because they suspected it was a bad logic board. So I got it replaced free of charge because it's covered under Apple Care.
I looked into the problem I have online and I'm not the only one with this problem. There are other people with the same model as mine or similar model as having this same issue.
I came across one person that had fixed the problem by finding out that it was a power supply failure.
I'm not sure it could be that. I was also told that it could be inconsistent flow of power. So I went back home to plug it into a surge protector and still turned off while I was using it even when it was plugged into a surge protector.
