3] Update or Rollback drivers

First, you need to uninstall the current version of installed NVIDIA Graphics drivers from your computer. Next, download and install the latest version of the driver from NVIDIA’s official download page.

We did this method instead of directly updating the driver because we have to reset all the configuration of the driver stored on that computer.

Alternatively, you can try to roll back the current version of the driver and check if that fixes your issue.

It should have helped you.
