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.
And this message comes sometimes after install a driver.
I tried many fix tutorials and no works.
