Solved Can't find the source of coiling sound/ high pitched whine

I'm hoping some of you have some advice on a coiling sound. It is a high pitched buzz sound. I'm sure you've gotten questions like this before, but I just need help identifying where it is. It doesn't make the sound 24/7. It's intermittent, I'll hear it for about 3-4 seconds and it goes away for about a few seconds and comes back. It happens on when idle and under load when gaming. I have a small idea where it is but I'm not 100%. When I'm looking at the computers insides, its kinda on the left center. If that helps :P

i7 3rd Gen 3770k
BIOSTAR TZ77XE3 LGA 1155 Intel Z77
Sapphire Radeon HD 6770 1GB
16 GB RAM G-Skill 1600
2TB Harddrive
Crusial M4 128GB SSD
Corsair TX750W Power Supply
Raidmax Altas ATX Mid Tower Case
G9x Gaming Mouse 5700 DPI
ASUS VE247H 23.6" LED Monitor
Windows 7 64 bit

That might be too much information but better more than less. All feedback is appreciated, as long as it isn't blatantly stupid =D

If you're sure it's not coming from:

the speakers
the piezo buzzer on the motherboard
the hard drive
a fan
something loose that may be vibrating

it may be a bad capacitor on the motherboard. They sometimes will whine before they fail (or blow up).

I tried all of the above, I actually booted it up without the CPU fan and the random buzzing went away. Thanks for the advice. I'm going to get a different cooler now. =D

✔ Best Answer
You're welcome. Yeah, a fan is probably the most common noise source. Sometimes you can quiet them down with a drop of oil in the hub but I think it's best to just replace it.
