directx function get device removed reason failed with dxgi_error_device_reset

If anyone has had these errors please can you advise how to resolve -

After playing B4 for a few minutes the game crashes with DirectX error messages. Unable to play for anymore than 10 minutes but ussually crashes after 2 or 3 minutes

I recently upgraded from HD5770 card and the issue wasn't present then it is only since putting in the new RX480 card.
