Sorry for my English,
After the installation of the new driver 18.3.4 i have many problems and the graphics card has became completely useless.
The problems are blackscreen, monitor graphic card signal lost, artifacts and more.
Without a driver, the card works normally.
I tried to install old driver but net has worked.
![driver.jpg driver.jpg](/t5/image/serverpage/image-id/6982i71402B57BA2FE6E7/image-size/large?v=v2&px=999)
And this message comes sometimes after install a driver.
I tried many fix tutorials and no works.
