I've just installed an Maxi iv Gene-z/Gen3 a few hours ago with an i5 2500k with an Sapphire 6950 1gb with an Zx series 850w psu and i've seemed to have come across a little bit of a headache, Its to do with the Sapphire and the pcie slots, They just won't talk to each other the gfx's fans are spining so its getting power and if you take the the pci cables out the videocard the fans still spin and the red no power light comes on so its getting power from the port, i've also tried it in my old Asus Amd board and its fine and posting, and to make matters worst my old ati X19500xtc(i think) works in both slots on the board so they are working too.
I've also tried moving the dvi cable around to diffirent ports on the videocard and booting the system up up to see if that works, I've also used an hdmi cable and it only seems to work on the onboard igfx port. Which i'm using now.
I've also double checked to see if the videocard was seated well but it seems fine and the power cables are in. I also tried another PSU to see if was power related.
I just wondered if you chaps have come across this bug before and maybe there is a fix, which would be lovely.
Also thank you for any help you can give.
If there is any more information you need let me know.
this is my videocard
this is the psu i'm using.
