Default 7800GS OC randomly buzzing

my 7800GS OC is randomly buzzing, and for no apparent reason. my temps arent high, the watercooling isnt leaking, i inspected the card and nothing seems to be wrong with it...though what worrys me is that the 12v rail (i have a 500w ultra xconnect, been lasting for a long time) is jumping from 12.100 to 12.300 every so often. the buzzing isnt steady, its like its trying to force a beep out. like

be beep beeeeeeeeeeeeeeeeep eeeep beeeeeeeeeeeeeep

im pretty sure its the power supply, but does anyone else have any ideas why its doing that?

weird, i took the card out and looked around a little more (still cant find anything wrong) and put it back in, and the buzzing stoped...but now my card thinks its a 6600LE? im gonna try and do some aquamark on the card to see if the performance took a hit, but nothing still seems to be wrong with the card...anyone else had this problem? and would BFG take a RMA even if i replaced the heatsink?

noooo...the bugger is buzzing again....i already did try cleaning out the drivers with drivercleaner, then reinstalling, and it still does that...checked the connections, reinstalled bios...maybe i should just RMA the card? (thanks to BFG's killer warranty?)

no way. this is LOUD. when i cover the buzzer the sound lessens.

edit...just tried taking off the waterblock and checking things out...would a oh so slighty chipped core do the trick?
