OK, let's have a step back here.
First, is your virus scanner still disabled? If so enable it.
Second, there are a lot of programs involved here without clear instructions how to use them, so lets check your Windows installation.

If anything goes wrong or if anything is unclear, don't hesitate to ask.
I did the windows powershell thing. It completed to 100% and had no errors. So I did the scannow part, and it completed with no errors.
One other thing, did it say that "Windows resource protection did not find any integrity violations"?
Everything has worked I'm on the last step. But I need you to clear things up with the last step.
Install the NVIDIA driver you downloaded before. Do it this way: Run the installation EXE > CUSTOM mode > install only the GPU Driver and the PHYSX software.Reboot > test.
What is the installation EXE?
