I did and is all Im getting from the event viewer
As Jorgen mentioned (and was not any problem linking one of my posts), e.g., this is what I see in the Event Viewer.
Maybe you could do a screenshot like this of your Event Viewer:

I suspected I knew the answer but I googled "nvwgf2umx" and confirmed that this is a NVidia driver component.

I recommend you use DDU and remove all NVidia components with Windows in safe mode (required to remove all files), then download current driver and install it.

nvwgf2umx.dll
That's part of the Nvidia driver. How about reinstalling this driver? I'd also recommend to clear the shader cache and then start the sim.

Delete the folder C:\Users\<user>\AppData\Local\Lockheed Martin\Prepar3D v4\Shaders. P3D will rebuild the contents, initial display may take a little longer than normal to render but that is normal.
