Hi John, I'm Graeme, an independent adviser here to help.
I'd recommend checking Event Viewer firstly to see if any errors were reported at the same time as this one.
- Click Start and type "Event Viewer"
- Select Event Viewer
- Under Windows Logs > System, see if an error occurs at the same time as the one you've posted, and if any further information is provided.
Otherwise, is the error recurring or has it only happened that one time?
Let me know how you go! Thanks!
