When I click the power on, the fan doesn't spin. I have to give it a small little nudge so it gets going. I took the fan off and looked at it and nothing. Is there something I can do to get it working right everytime? I haven't installed a processor or RAM yet, but it does this when I power on the PSU. All the other case fans work. The fan moves on its own every 2-3 times I turn the PSU on. Its a good thing I discovered it before I started using the computer or I would have had some heat damage. It's a BFG nForce4 Ultra.
