i got a new graphics card today it is a gigabyte radeon r9 270x and when i plug it into my motherboard with the power cables securely in and the card also in securely i just get a screen with no signal on it but if i unplug the graphics card and use the onboard graphics on my motherboard it works fine but if i do that with the graphics card connected then i get no signal again any suggestions would be very helpful
