    My new 5k, maxed out iMac started having video glitches, especially when playing Diablo 3. Then it quickly would reset itself, then it would boot into recovery mode but also then have video glitches and freeze then reset itself. THEN, internet recovery mode would load and then also glitch and restart itself.

    At this point, the SSD also seems to have gone bad as I get the "no" symbol now upon trying to boot. And after resetting all smc, nvram, pram, whatever, it's basically bricked. This happened all in about a 30 minute period.

    At first I thought it was a video card problem, but then when I couldn't boot to the SSD or recovery partitions, external OS backup, or internet recover, it seems to be muck deeper.

    I have apple care, and it's only 2 months old. Has anyone seen this happen? Is there some known issue around a logic board or both the SSD and video card frying on a new 5k imac? Super super disappointing to drop 4000$ on this to have a total meltdown.

    Based on your description it sounds like an issue with the logic board. Even with a bad GPS and SSD it should be able to boot from an external drive. I would give Apple a call and take it from there. It should be fairly straight forward since it is only two months old.

    Bummers man, sorry to see your iMac to fail so quickly. So far there is no trend to back up your concern. You may have just been unfortunate to deal with a defective logic board.

    Have you checked the RAM? What happens when you power on the iMac holding "D" to run the onboard diagnostics?
    Sounds like the Logicboard/GPU. Sorry that happened though, definitely a bummer. If it does require repair at an Apple Store it normally is 3-5 business days in the USA which is not that bad. Still sucks to be without the machine though. Hope it is resolved soon.

    I got a full refund and now can buy a new machine, so I guess that's the best fix you can get.

    Well that's a nice outcome, given that you had the computer for 2 months. Good luck on getting a replacement - hopefully this will be the last of any issues that you've had
