When I’m using my mac, at random times , it suddlenly frozen and the image gets all broken and it starts to make a noise and the only thing I can do is press the button to shut down and when I power on only appears a meesage box that said that the computer didn’t shut down correctly if i want to restore the programs I was using. I run Apple Hardware Test several times but it founds nothing. In the image you can see what happends.
Thank you for your help.
It looks like the graphics is starting giving troubles. To confirm it’s not a screen issue plug in an external screen or tv when the issue shows up..if it’s present on an outside source too a board issue would be confirmed. If that’s the case, you’d need either a board repair or a replacement.
