What Graphics Drivers & Version number did you install?I installed Automatically detect and install the driver on the AMD website
Radeon™ Software Adrenalin Edition 18.6.1 is not even supposed to be supported for that GPU.I have two video cards, this driver is only under one of my video cards.
This is what your GPU should support. https://support.amd.com/en-us/download/desktop/legacy?product=legacy3&os=Windows%2010%20-%2064
So double check your GPU is in fact one of those listed, and if so, uninstall the Adrenalin Drivers, and install the ones from that page, either the Crimson Beta, or Catalyst.
I would suggest the Crimson Beta version as the GUI in that version is way better than Catalyst, but the Catalyst version is more likely stable.
