Thank you for posting on the HP Support Community.
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:
Did this happen after a recent window or software update?
Have you made any hardware/software changes?
Did you make any changes on the settings of your PC prior to the issue?
When was the last time it worked fine?
Use the following steps:
Shut down the computer, and then inspect and clean the exterior vents to remove dust buildup by blowing air through the vent openings. Dust can accumulate inside the vent openings and around internal cooling components, preventing the removal of heat.
After you remove the dust, turn on the computer. If the error message persists, continue with these steps.
Perform a hard reset. Performing a hard reset can reset recorded thermal values in memory and enable you to use the computer again, even if only for a short time to access and save any important files before service.
