Computer making a small vibrating noise

[dlf]

Built http://pcpartpicker.com/p/P5kr (except for 8 GB of RAM, not using that monitor, and using the stock CPU heatsink) it seems in the last day or two the left side of the case has started to make a small vibrating noise. Anyone have ideas on what's making the noise?

Should also add that the system is on bamboo floor in Dallas, also have gotten a few BSOD as well.

It might be due to a number of things. Do you have a disc in your optical drive? They're probably the noisiest components next to fans.

It could also be your fans or hard drives, but that's less likely.

The optical drives work fine, just opened one (with a disc inside) and the noise is still there. Both drives can read a disk fine, doubt it them.

Fan filter rattling in it's rails?

I did shut down the system, boot into BIOS open the side and (not on purpose) pulled the fan from the motherboard - I think the sound's disappeared, so it appears it was my side case fan making the noise, and now why?

Your CPU cooler may have loosened its-self, so maybe try making sure that it's snug to your motherboard.

The system is now making normal sounds

So it's fixed?

make sure your fans are not vibrating, check heatsink check all parts if they are tightned and in place.

Yes cept now I my side fan isn't connected or working. Will most likely have to plug it back in later.
