[QUOTE="Bcaruso22, post: 1906209, member: 411159"] Hello all, new to the forum and I am hoping someone can confirm my suspicion. As the title states, I own a late 2014 iMac 27”. A few days ago my screen went all haywire and ended up having to power it off with the button. I let it sit for a few and turned it back on. I was greeted with a screen I’ve never seen before. Lots and lots of white and black rectangles. I’d get the Apple logo and progress bar in a clean area. The white would turn a reddish color and then I’d get a message stating it had an issue and was rebooting. This was an endless loop. I’ve tried resetting all the go to things. NVRAM, SMC, etc… I noticed I’m not hearing my fan on boot up, haven’t confirmed if it is or isn’t working yet. I’m thinking I had a fan fail and over heated my graphics chip. Any thoughts? [/QUOTE]
