Product: HP Pavilion 500-164
Operating System: Windows 8.1

I have a HP Pavilion 500-164 . Every time I start it up I get an error message of 511--CPU fan not detected.

At the bottom of the screen it states    F1  : Boot

Then it starts to operate without problems. This is becoming bothersome.

 

But when examining the unit, I find both fans running?

What is the problem and do I need to take it in for repairs?
