I built a computer with
Corsair hx750 PSU
Corsair vengeance 16 gb 1866 mhz
Z77 sabertooth motherboard
And using a dell IN2020M monitor
I have a XFX radeon hd 7870 graphics card everytime I hook it up and put both the 6 pin connectors from PSU no display will show. I hook up my older hd 5670 card and it works fine with the same cable (DvI-D to HDMI) used for my new graphics card. Is this graphics card dead on arrival or can someone give me a clue as to why the screen won't work when I am using only this card?
