Fan Problem on Startup

Hey everyone. About 3 months ago I built a computer (specs are in my sig) and I haven't really had any problems until now. Basically, when I start up my computer, one of the fans starts making a loud buzzing noise, like something is caught in it. During this period, the fan speed varies up and down.

This occurs when my comp is loading the OS -- once I get into the Windows screen, the buzzing stops within a few seconds. I've had no luck figuring out which fan is causing the problem (the BIOS fan speeds aren't reading any changes) and when I can't use any Windows programs because the fan has already stopped "messing up".

I haven't noticed any negative effects thus far, but it doesn't SOUND like a proper noise... does anyone have any advice about how to treat it (if it is indeed something bad)?
 
It sounds like there maybe dust or summin in the fan causing it to vibrate. You could try removing the fan from the heat sink and giving it a good clean. Maybe even lubricating the bearing system with some oil/lubricant.
 
If there was dust, it seems to me that the problem would continue... however, it stops when Windows has loaded and has never continued for much longer than the start-up process. Am I correct in thinking that?

that has a good point to it, it could just be that your system needs to use a good bit of wattage to boot and that after it has booted up, the cpu settles back down.
 
That's possible. However, I am a gamer (as is evident from the hardware) and I've never had it occur when playing games, even with graphics pumped on power-hogs like Battlefield 2... I don't think my GPU runs at full speed when my computer is idling.

true, true
 
Thanks for the suggestions, Monkey...

Anyone have any other ideas? I'm concerned that in the long term this will damage my hardware.
