Hmmm, there's one option left. No guarantee, as the problem may still be a GPU hardware issue in the cores.
We have had a couple of users where driver updates and installs did not resolve things. However, a re-install of Windows, and then drivers and software worked. The options are for either just a Windows reinstall, or a complete and clean re-format and install of Windows. Of course that requires a reinstall of everything so will take a bit of time.
Don't forget to fully backup any data on the system before proceeding.
