1. Is this new card, if not, have it worked in the other PC?
2. Have you disabled on board graphic card (embedded) in the Device Manager?
3. Have you install latest AMD drivers?
I doubt you can hear this card, because it is fanless - it has no fan, if it does, can you provide full model number or link, I got this from newegg http://www.newegg.com/Product/Product.aspx?Item=N82E16814102882
is it yours?
