    Signs Your iMac GPU Is Failing

    Your iMac’s graphics processing unit (GPU) is a big deal: it’s the main component in your computer that tells graphic images how to show up on your screen. Pretty important right? Especially given the trend toward all kinds of images all over computers and all over the internet. It’s getting increasingly hard to navigate the digital world without proper image rendering. Agreed? So, what happens when the GPU fails? A number of things actually.

    • Artifacts

      Artifacts (odd shapes) on your screen. You could start seeing images looking weirder and weirder.

    • Lines or Black Screen

      Lines across the picture, or a black display after the startup chime. The diagnostic tells if it’s the screen.

    • Freezes and Shutdowns

      Your computer freezes up. Sudden shutdowns. Performance issues.

    • Heat and Fan Noise

      Strange fan noises. Overheating.

    Usually a Board-Level Repair

    On most iMacs the GPU is part of the logic board, not a separate card, so the repair starts with the diagnostic.

    Software

    Software incompatibility and driver problems can look like a failing GPU.

    Hardware

    Overheating, a manufacturing defect or physical damage. Board-level work may go to our Manhattan lab, and we tell you first. See iMac logic board repair.

    What to Do Right Away

    As soon as you suspect your GPU is failing, shut down your computer right away. This will prevent further damage from occurring.

    A faulty GPU can cause damage to other components inside your computer—the sooner you get it replaced, the better.
