my mother board is stock Gateway DX4870-UB20P
with upgraded CPU Intel i7 2600 quad core.
my normal card is GTX 560
I've noticed when I plug the GTX 960
with power, and proper connection.
the resolution is changed, to about half the screen
and the only thing visible is the gateway logo, f12 and DEL not working
and starts to beep, eventually turns black with flashing underscore in the top left corner.
thanks with for any help
