iMac 2011 with a biggest problem

Hi

I have a iMac 27" from 2011 and yesterday i have a problem, when i work in images in full screen, my screen is going crazy, first frozen and after that its appear lines in horizontal (i think is in horizontal not vertical).

So,i need to turn off the computer by the power button (i try to turn off by keyboard but don't work). After that i turn on the iMac and everything works fine, when i start working again in images the iMac have the same problem, so i turn off.

Today i'm trying to turn on and the iMac is rebooting, ( i leave a video to show in few moments) , and stay making this ever and ever again.

Im trying to diagnosting the problem with the key D but i can't enter, still a long time in grey screen and after that enter with Apple logo.

The iMac is out of warranty but i like to know if is enable to replacement program, because i think is the graphic card.

iMac, OS X Yosemite (10.10.1), 2011

There are no active replacement programs for that model, I believe. However, I would take it in to your local Apple shop to find out. The old program for the display panel may still be active.

I check now this page iMac (27-inch): AMD Radeon 6970M Video Card Replacement Program - Apple Support and i fond one line we say

"If the iMac (27-inch) meets these requirements, Apple will replace the video card free of charge for four years after the first retail sale of the computer."

🙂

That should cover your machine, since I just had mine replaced last week. It exhibited some of your symptoms.

I send the iMac for a Apple center and have the information it is a graphic card and a hd, why the hd too? because the times i need to turn off manually and the many time the iMac reboot alone.(the Apple center don't say me that, but is that who i think)

The graphic card have the replacement program in Portugal too 🙂 so i have a new one, and i change the disk to don't have other problems in future.

I'm testing the iMac and one think i see is more fast, but have a lot of noise, i think that can be a graphic card fan, it is normal have a fan noise or disk noise?
