Solved Need help Pinpoint source of computer Clicking sound

Self build / N/A

Specs: Vista Ultimate, SP2, 3.0Ghz/2Ghz
It seems my computer has developed a clicking sound. It sounds like someone tapping from inside the case. Any idea on what this could be? Might it be a case fan? Or perhaps power supply? Thanks.

Problem resolved! One of the wires that belong to the CPU fan power connector was being scraped by the CPU fan blades. Didn't suspect that at first but after taking two chassis fans out of the loop, the clicking persisted. I zeroed in on where the sound was coming from and saw one of the CPU fan connector wires hanging in front of the CPU fan. I gently moved the wire forward from the fan so that the fan blades did not touch the wire; the clicking stopped. I have dressed the wires around the CPU fan assembly so that this doesn't happen again.

If you are lucky it might just be a fan, perhaps something caught in it.

As often as not clicking sounds come from a hard disk that is about to fail, so I would backup your files ASAP just in case.

EDIT
After you've backed up, have a listen to some of these sounds to see if one matches:

Always pop back and let us know the outcome - thanks

Open up the case and see if you can find the source. It's either a fan, something hitting the fan blades, an arcing electronic component or a drive.

Visually look for a wire or something leaning against a fan. Look inside while it is running to see if you can narrow down where the sound is coming from. Make sure that you have the machine off before touching anything inside of the case, then touch a metal part of the case (to ground out any static potential you may have), then unplug it. Loose wires should be tie banded in place to prevent this sort of problem, left unfixed can wear through insulation and cause other problems. If the sound is coming from a hard drive, verify your back up and since it is still working, make an image of the hard drive to an external hard drive ASAP. Then make a Windows 7 Repair Disk (Note: I just saw you have Vista, i think it also offers this option in the back up section but I am not sure), then purchase a new hard drive. If the drive still works, you can clone the drive to a new one directly, but if it does not continue working long enough, you can use the drive image to restore it to the new drive with the help of the repair disk (If Vista does not have the disk image and repair disk options, you may want to use another program to do this. Acronis and others are available, Western Digital offers a free version of Acronis if you have or purchase a WD drive.).

You have to be a little bit crazy to keep you from going insane.

Use a Paper towel tube or similar to your ear to isolate the sound with the case cover removed. Piece of hose also works great.

Yes, I've even used a stick of wood to pick up direct vibrations but the hose sounds like a good idea too. Without something like this the fans blow the sound all over the show and it can be quite misleading.
