My 770TA-UD3 won't post, it gives one short beep every 10 seconds (I think it’s cycling) and a black screen. I have tested the CPU, memory, video and power supply with an Asus board and all work as expected. I have tried every memory configuration with no change. I have tried a different video card from a pci slot. This is the second board with the same problem (rma the first). Has anyone else experienced this or have any ideas. Any help would be appreciated.
