I just replaced my power supply. I noticed there was 1 wire that was not on the new power supply.
It was a 3 pin wire. The computer seems to work fine except for when I do a reboot I get a message
stating power fan problem. Hit f1 to continue. Is there a way to get rid of this message? The fan in my power supply seems to be working fine and all the two other fans in the computer seem to be working fine also.

Welcome to Geeks2Go!

The 3-pin connector on your old PSU connects to the motherboard and allows for system monitoring of the fan speed. In your case, the BIOS now detects the 3-pin connector on the board has nothing connected to it, hence the error message. You may find an entry in the BIOS setup to disable the fan monitoring feature so you don't the error message.
