I am not sure since when, but i think NVIDIA 960m started freezing after updating Intel HD graphics 530 driver.
I tried Display Driver Uninstaller for both NVIDIA and Intel in safe mode, then re-install all the drivers once w/ the latest versions, and after being no help, second/multiple more times using previous versions.
Non of them worked, and I still can't get NVIDIA to work.
Below is what happens when I open NVIDIA control panel. 3D preview does not rotate, and the control panel freezes.
Also, running OpenGL in Visual Studio 2017 freezes, while other non-OpenGL programs run fine.
It seems that some conflict between Intel HD graphics 530 and NVIDIA 960m, but not sure.
I have to work, but this nonsense problem has got me stuck for two days.. very stressful.
