looks for dust or loose fan plug. This can also be cause of bios error. Check if any latest bios is available and update to it.

Possible reasons are :

1. CPu fan gone bad.
2. Bios has some sort of automatic fan control option which won't let the fan spin unless the cpu heats upto a certain limit.
3. The cpu fan pin on mobo malfunctioning - try some other 4 pin fan header .
