When I start my computer it says: "Warning!:Cpu Fan Fail"
I can't find any fans that aren't working, how can I fix this?


Thanks.

Your CPU fan will be the fan on the heatsink on top of your processor on the motherboard. Is this fan spinning? Most likely if it is, it is either too slow or the RPM monitoring your system has is not detecting the fan.

A new fan might fix it if the RPM monitoring went out on that. Do you know what temperatures your computer is running at? What kind of computer is it?

the temp is about 30c, and I got the computer yesterday from Cybers, AMD Athlon 3000.
Could it be because I messed around in the bios?

Has it done this from the first boot? Did you reload the defaults in the bios? Does the processor fan have 3 wires going to it or 2?

You probably turned RPM monitoring back on in the bios by resetting it. Open the case up and carefully check to see if there are 3 wires. I'm guessing there are only 2 (red/black). If there are 3, the 3rd will be yellow most likely. The wire plugs directly into the motherboard.
