ASUS F1A75-V Pro - F1 Socket - A75 - SATA 6Gbps and USB 3.0 - ATX AMD (Hudson D3

[frumenti]

I just purchased this MB and I have installed the qualified ram and cpu. I get no video and the board locks up at post code AF. I have moved the ram around to different slots, tested with different power supply and still no luck. The MemOK light does not come on upon boot up but if I hold down the MemOK button for a second or two the MemOK light blinks red continuously and never stops until I power down the board. This board has the bios replacement called UDFI. Anyone have any suggestions?

Thanks in advance for any help.

Any beep codes, like 1 long - 2 short (RAM issue), 1 long - 3 short (Graphics card issue), 5 short (CPU issue), etc.?
