My brothers R10 3080 just died as well. Dell remotely took over his comp and ran some tests and it was bad. They sent a repair tech with a new 3080 and now its working flawless. His card worked from the start then started crashing every 6 hours, then 3, then maybe last 5 minutes. Though the repair guy had to reschedule 3 times it is a step in the right direction at least.
Hi everyone, I received my Alienware Aurora R11 with the RTX 3080.  After 30 minutes of gaming, my screen starts flickering and after 10s my screen is black and I have no choice to turn it off and back on. I have done all the updates: windows update, Alienware update and MS store. I tried to restore it as new and same problem. I noticed that if I let my computer rest for 30 minutes it would work again for around 30 minutes of gaming and then same problem... I would guess my GPU has a high temperature problem but when I was monitoring with MSI Afterburner, it was around 65 degrees C.  I tried to replace the GPU with a GTX 1080 and everything works fine. I called the customer service and it seems that my GPU is not working properly... They are sending me a new one. Anyone has experienced the same issue? Before the 30 minutes I was able to run a benchmark and my previous PC got a better score   [IMAGE]
