I think it is overheating. I called the help desk and they said I can send it in and get a loaner machine while they look into it. I’m not sure if I want to do – seems like a pain to mail it around. I heard they send you the box to use for mailing but who knows.
For now I have a small fan pointed at it and that seems to be working. I also diddled with the power settings to try to make it generate less heat.
