Extremely high cpu load AMDRadeon+Intel Graphics

I have Radeon Pro WX3100 mobile GPU running with Intel graphics 620.  In task manager, the "System" process is always running at 100% on one core.  This process is tied to ntoskrnl.exe (when I click on the process and go to properties).  This makes the computer unusable, not just annoying, when using 3D applications.  This process runs constantly.  It happened out of the blue without the installation of any new software.  Also, there were no updates to Win10.   I installed no driver updates.

 

What fixes this:

Device manager > Display adapters > Intel HD graphics > Disable

      The "system" process returns to normal

 

OR

 

Device manager > Display adapters > Radeon Pro WX3100 > Disable

      The "system" process returns to normal

 

Both enabled at the same time creates the problem

 

I have tried:

1) Uninstall ALL drivers

Reinstall Intel HD graphics driver (Using recommended driver from HP Image Assistant) then reboot

Reinstall Radeon Pro driver (Using recommended driver from HP Image Assistant) then reboot

 

2) Uninstall ALL drivers

Reinstall Intel HD graphics driver (Using recommended driver from HP Image Assistant) then reboot

Reinstall Radeon Pro driver (Using recommended driver from AMD) then reboot

 

3) Turn off all security settings found in Windows Defender

 

4) Updating Win10

 

5) Updating all out-of-date drivers (Using recommended driver from HP Image Assistant)

 

6) Booting into safe mode.  This is OK, but no graphics drivers are enabled, so I would expect this to be OK.

 

   FYI... HP Image Assistant is the driver scan tool from HP for workstation class models
