Are you sure you are plugging the little card in correctly, the notch should hang over the end of the pcie socket. Bad things happen if you turn it the other way. Have you tried them one at a time? Do you use dummy plugs? I'm sorry, I don't really mine in windows, so these are the only issues I can think of. Switch to xubuntu or BAMT, nice and easy!
