This PSU may be not enough for your very powerful GPU
2.Delete C:\AMD folder
Try 16.11.5 first
4.Run HWinfo64>sensors only>Logging start and play for 15-20 min. I want to see that log
I did, what you told me. I played one round Fifa 17, ~ 15 minutes. No blackscreen
But I think that the problem isn't solved because the blackscreen come randomly. Sometimes the blackscreen came during the first round. Othertimes the blackscreen came after eight games or more.
The logs of this one round game are attached.
I don't think that the issue is the PSU because I got already problems with a 650 W PSU. And over 1 1/2 years this was enough.
Edit: I tested it with FurMark. I got a Blackscreen while testing. Logs are attached. I found out that the GPU current drops sometimes from 200 A 80 A in a second and in the next second it's again at 200A
Your logs have mostly incorrect info. I don't know, maybe your motherboard is faulty. You must try your GPU on another PC. I think this is the only way to understand what is going on
