Windows 10 CPU usage 100% when Nvidia GPU enabled

I've had the same problem, and have exactly the same GPU model. I was able to set the drivers back to factory default, but any update I've tried (including the most recent) causes the massive cpu usage. I've contacted tech support for both Nvidia and Asus,
and followed all the steps they suggested, with no luck.

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Cripplingly High GPU in Windows 10

Dave, the two processes apparently hogging all the GPU were desktop windows manager and client server runtime process.

However, when I list them now, after numerous reboots and reinstalls, no apps show up as consuming GPU, yet GPU is at 80-100%. I think this is because the apps are only consuming the 3D component of the GPU and not the others - copy, decode, processing or
shared memory usage?

I've spent some time on Google and it seems to be a fairly common symptom but none of the suggested solutions are effective.

It doesn't seem to be linked to any significant changes, I even tried uninstalling the most recent windows updates.

Any thoughts?
