I was playing Ark with no problems on my Radeon RX 480 ARMOR 8GB then screen changed colors and now the gpu only gives moving vertical lines. I have uninstalled drivers and tried to reinstall but it just crashed once it got to instaling amd display drivers but then I checked and it apparently updated to a driver that came out in Feb 2020. I used amds software like driver uninstall and such to do so. There is no burn marks on the gpu. I've tried new thermal paste nothing works.
