Radeon HD 5770 buzzing

I just finished building my first gaming rig, summarized neatly in this thread.

Here are the relevant bits:

AMD Athlon II X4 630
XFX HD-577X-ZNFC Radeon HD 5770
GIGABYTE GA-MA770T-UD3P AM3 AMD 770 ATX AMD Motherboard
CORSAIR CMPSU-450VX 450W ATX12V V2.2 80 PLUS PSU
SAMSUNG Spinpoint F3 HD502HJ 500GB 7200 RPM 16MB Cache SATA HDD
Antec Three Hundred Black Steel ATX Mid Tower
Windows 7 64 bit


Since the moment it booted up however, something has been buzzing like crazy.
It's a constant buzzing sound, like a bug zapper or a defective fluorescent lamp (if you've ever heard one of those), but loud! It's pretty hard to describe further, beyond that it is the most grating, annoying sound I've heard in the past few months.

It's constant, and occasionally changes pitch in sync with hard disk activity or mouse motion.

Initially I thought it was the PSU making the buzzing noise. I'm still not sure if it is. So I RMA'd it, especially since other people were complaining of buzzing (not the same kind) on the Corsair forums.
The buzzing hasn't stopped even after the replacement.

Now I think it's my graphics card. When the PC boots up, there is buzzing for a second or two, then everything goes quiet. When the Windows login screen appears, the buzzing comes back and stays as long as the PC is on. When I tried running Linux, everything was silent until I installed the ATI Catalyst drivers and activated my card. Then the buzzing began again.

Do you have any suggestions? Should I RMA the card? Try reseating it in the PCI-E slot? Does anyone else have this problem? Note that I still can't identify the exact source of the buzzing.

Just clarifying: This is not a buzzing sound that occurs when the GPU is stressed in a game. This is a loud, constant buzzing that begins at the Windows 7 (or Linux) login screen and doesn't go away.
