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.

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.
