Hello guys, I have a DCU II HD 7850 from back in the day that only recently decided to die. The problem I am experiencing is that the card doesn't display anything on my monitors, I tried DP and HDMI but nothing. I can boot with my 1080 into windows and I can see that the gpu is recognized but in device manager it gives code 31, GPUZ does see the gpu but usual no drivers stuff where it cant count the memory size. When I try to install radeon drivers I get black screen and gpu fans ramping up and down. Only thing I have tried to do is thoroughly clean the card with soap and alcohol, but that didn't change anything. I wanted to try the dmgg memory tester, but I have to fill in the 15 post quota to download it, so might as well ask here for your opinion on the matter .
edit: I forgot to mention that the resistances on every rail is ok. If you want me to check the values again i can do that, because i forgot the exact values, but i know they were in normal range.
