I am sorry to hear that have had issues with driver versions on your computer.
The computer keeps updating to the latest video driver 3379 because you have enabled Microsoft Updates. Since this is a new update the computer will always try to get the latest version.
You may try to run system restore and place your computer on an earlier time. Or, try to get version 3257 from your motherboard manufacturer's web site.
Actually I have automatic update turned off in Windows update, has been for months. I only allowed Windows update on 10.18.10.3379 because of the instability. I already tried re-installing 184.108.40.20657 by using the overwrite switch, but that did not improve the situation. My take is that 10.18.10.33xx was not completely removed, so forced re-install of 220.127.116.1157 was unhelpful. That leads us back to the same problem, I need to have a way to completely uninstall 10.18.10.33xx drivers.
I am afraid at this stage; you will need to re install the operating system to get driver version 3257 back to your system.
