Likely a GPU failed. Please take the computer to your local Apple Authorized Service Provider ( Apple Authorized Service Provider Locator (AASP) & Genius Appointment ) to be professionally diagnosed. If it is the GPU, then it's time to replace the computer as the GPUs on machines made in the past 10+ years are a which on the main logic board that is not replaceable . And a new main logic board (assuming your computer is not obsolete) is very expensive.


However, if the computer is covered by AppleCare then that repair would be covered in your AppleCare.
