Work-around to stop Windows PC Overheating
In Windows Run box (Windows Key + R) enter following command to lower the Control Panel ‘Maximum processor state’.
control powercfg.cpl,,1
Scroll down to ‘Processor power management’. Next, click to expand ‘Maximum processor state’, then set the ‘On battery’ and/or ‘Plugged in’ percentages to less than 100%, e.g. 80%.
This should prevent the CPU overheating, i.e. reaching the maximum die (Tjunction) temperature and shutting down the PC.
