I see you are aware of the defect but what can really cause you to lose all remaining hair and sanity is it can fail, then come back then fail again.

You see folk "re-balling the GPU", baking the motherboard and more to bring it back. I do not endorse ANY of those methods but it's your hardware, your choice. Why can't I endorse any of those? Because at best it's temporary and doesn't address the issue directly. Any shop could get itself into trouble if it did any of the shade tree mechanic fixes.

Hope you fair better now that you know.
