Mobo causing coil whine?

[derrickd241]

Could the mobo actually cause coil whine? I'm trying to figure out a coil whine problem even though its more like a buzz then a whine. I've RMA'd my graphics card twice ive checked my fans, and I now have a new PSU that I haven't tried yet I thought it was the PSU because I only have a corsair 430w with an athlon x4 760k and an Asus r9 270x. Asus says the minimum is 500w so i thought it might be that. My card buzzes when under load such as playing a game. It also buzzes when I'm in the bios settings, After about 10 seconds this thing just goes nuts and its driving me crazy.

Have you tried taking out certain pieces then booting up and see if you can pin point the problem ?

I can hear its coming from my graphics card but that's obviously not the problem what else could I take out to try?

I just don't get why I'll have buzzing in the bios but not when I'm in windows unless I'm playing a game
