I seem to have cured the problem by removing a non-critical Microsoft update. I am keeping an eye on this issue.
This is known as a "DPC latency issue". There are several tutorials and software tools available online that you can use to troubleshoot the issue, if it was not yet solved by any chance.
Let me know if you still need help with it.
