cpu fan error

I have the asus 845 motherboard , display the error [COLOR=rgb(0, 0, 255)]“CPU fan not correctly fitting” and system goes to down but my CPU cooling fan has fitting correctly, how to clear the error

Check the fan to make sure it is running, Next go into the bios and see if there is a spot in there to clear… If not ! Try removing the bios battery for a couple minutes..
