Built a new system with the Asrock 970 extreme4 - took out the video card from my last system (it was working fine), put it in the new system and it won't boot up (5 beeps, d6 code). Tried reseating, all the other slots, etc. - nothing. Put in an older card and it works fine. The card I'm trying to place in it is a Gigabyte 5750 GV-R575SL-1GI.

Oh yes, I have the latest bios as well.

Thanks in advance!
