I have been trying to install a pair of new R9 270x cards into a gigabyte GA-Z77-D3H mobo (fully compatible with the cards, I've triple checked). Power supply is 850W so that shouldn't be the problem. The computer boots fine on the iGPU, but as soon as the cards are seated and powered the computer will not boot. It will power on, fans will spin up, but nothing will happen--no beeps from the mobo, no lights, nothing else. I'm in the process of flashing the newest BIOS to the mobo to see if that has any effect on it. I also have made absolutely sure that PCI graphics are enabled as primary in the BIOS.
Is there anything else I can try or something I'm forgetting? Really hitting a wall here. Thanks for the help.
