Logonui.exe Error?

I woke my new Windows 10 installation from a six hour sleep which worked OK. I then logged off that account and then had a black screen with no response to Ctrl/Alt/Delete.

I pressed the reset button to reboot and looked at the error log to find the enclosed error report.

I've done a Google search but can't work our why this happened. SFC/ SCANNOW runs with no errors.

Hello Steve,

Has this problem occurred again or was it a one off?

It's a one off to date. I've now disabled the AMD Adaptive Sleep Service since it appears to have no useful function in case that was interfering with something.
