Hello, guys.
I appeal to you because I have run out of ideas.
Everyting started when i updated my pc to win 10 pro x64. It was an old version, 2015. I saw that i had an old version of amd adrenalin (2017, don't remember wich. Everything was fine here) and i tried to get the last one. So i did it, i installed adrenalin 2019 and then i started having video errors like black pixels/lines on the screen, or the screen goes black like if my pc was turned off. I updated my w10 to the last one (october 2018) and just there i could see that Wattman error. I uninstalled/re-installed drivers (several versions) and didn't fix it. I checked my RAMs, my graphic card... Hardware looks fine. I tried to modify the temperature as I saw in an old post but I do not know how in the version 19.2.3/19.2.1/19.1.1/18.12.2.
So,
WINDOWS 10 PRO x64
AMD FX 6100
16 GB RAM DDR3
ASUS M5A97 R2.0
AMD XFX RADEON HD 7750
Thanks for reading.
