terrible noise

hi mate, i receive the board and connected to my Chinese Arduino NANO clone, and Nothing. Some beers after i found that the problem is the wires not connected in the correct place. Now the board it's working but you can only hear some sound in the middle of the noise. My questions are: Chinese arduino sucks? My computer power switch sucks? I try to power up the board whit an external USB power switch, but the noise still remains. I will post some photos and audio file to show what im talk about. Thank for the Board, Romeu
