A bit urgent: No display on 7950

[Orija]

So, I got a new Sapphire 7950 Vapor-X today. I've installed the card into the PCI-e 3x16 slot, attached two 2+6 power connectors. There's no display on the monitor on booting up, the gpu lights up and the fans do move on switching on the power button.

The onboard graphics adapter is working.

Motherboard is Asus P8Z77-MPRO. PSU is Corsair TX650 V2

Are you leaving both plugged in? If so, disconnect the onboard cable.

If you aren't, check the bios settings while using the onboard.

Nope, I'm only using one at a time.

The Primary Display option in Graphics Configuration is set to Auto (the other to options being PCIe and iGPU) so I don't think that is the problem.

Try a different PCIe slot?

 

[Orija]

Okay, I'll do that.

Edit: Reseating the card on the same slot did the trick.
