Hello James,
Very strange indeed. I am able to view the images, so I can see what is happening on your end, but unfortunately the images do not provide answers to the questions I posted earlier. If you could please provide answers to the following, we can hopefully start root causing this issue:
What is the version of Dell Support Center on the system?
Is this the original version?
Where there updates performed to the system (hardware or software) prior to the start of this behavior?
In regards to gusvc, I cannot think of why a google update service would interfere with the system history, but that is not to say that it isn't You can always try to disable the service on your system to see if it resolves the issue.
Thanks,
