Gigabyte HD 7950 not working in Asrock Z87M Extreme 4 mobo

I have just installed Haswell i5 4670k CPU into new Z87M motherboard with 8 gig RAM. All works well off the onboard graphics, as soon as I hook up the 7950 no go. The screen appears black, no splash screen, nothing. I am using a DVI cable, not dual link DVI, however I had this working in another system just fine.
Any ideas?
Unit is powered by a thermaltake 875w PSU, has 120g SSD for windows and 1Tb sata for data.

  1. Power connected to the card from the PSU and monitor hooked into the card?
  2. Use integrated graphics to update your motherboard drivers, this is a common issue with the 7000 series.
  3. Hello Gents, Yes Rolli59 I do have all the power connections in and the monitor hooked into the card, lol. I have checked all the cables to see that they were well seated and can`t find anything out of place.

    abdbgames, have not tried that as yet,but I will give it a go in the next 10 mins mate, thanks.
    I did update the bios, thinking it might be an issue, but it didn`t give me any joy.

    If the card is working in another system points to something wrong with the slot on the board.
