Hi ThomasN -
Thank you for your report. We have assigned this issue to a member of our support staff, and they will begin investigation as soon as possible.
As you have said that this issue is not crashing the editor, can you please open Windows Event Viewer and look for the Critical and Errors that occurred around the time that your CPU crashed. You can save out the logs from the Event Viewer as a evtx file and zip it up and attach it here or copy and save them out as a txt file and directly attach here.
Please be sure to review our suggestions for how to report a bug, and feel free to add to your post if you have additional information to provide with the Event Viewer Log Files:
Thank you -
Eric Ketchum
