Question RX 470 trouble

[hoangvietha]

Recenly, I've bought a RX 470, everything is fine while I'm not play game, but when I open a game, the game crash, sometimes everything crash and my monitor like old TV when it lost signal:

My specs:
I5 3470
4GB RAM
RX 470
Golden Field 480W
Using an HDMI to DVI-D to connect with monitor
(I can't send it to guarantee because it too far for me to reach there (about 500km))
Bad English sorry
