No signal on monitor?

Recently I purchased a Radeon HD 7970 3GB video card, but when I hook my monitor up to it (Sceptre X246W-1080P LCD Monitor) I get "No Signal"

I use a DVI to DVI cable and have set my monitor to DVI, HDMI, and VGA, and they all yield the same No Signal result. When I hook my monitor up to the on-board video, it works fine. It also works fine with an older Radeon card.

Can anyone help me out?

  1. What power supply do you have?

    Did you plug in both 8 pin power cables from the psu?
  2. Corsair CMPSU-1050HX

    And yes.
  3. Not sure why you would need a 1050w psu, as a 500w would be sufficient, but maybe it croaked?

    Have you tried different pci-e power cables?
  4. All of the components are new.

    Is there a way that I can check to see if my video card is recognized by my PC, even though the monitor is not hooked into it?
  5. I don't know what mobo you have but some basic things you could try is look in bios to see if you need to change it from onboard to PCI-E video adaptor.

    You could also try pulling the cmos battery for 5 minutes, then put it back in and see if that works.
