No Post-Beep / Failed Start-up

[aquenne3]

I just built myself a new computer and am experiencing a significant issue. When powered, the motherboard is not making a post-beep and there is nothing showing on the display (aka no boot sequence). There following is the components of the machine:

Motherboard - Gigabyte GA-P55A-UD3
Processor - Intel i5-760
Ram - Corsair Vengeance 8Gb 1600 MHz
Graphics - EVGA Geforce 9800 GTX
Sound - Creative X-Fi Titanium Fatal1ty
Power Supply - OCZ 750W Fatal1ty
CPU Cooler - Corsair H70
SSD - Crucial 60GB C300
Case -  Antec DF-85

I have replaced the motherboard, CPU, and power supply. I have tested another graphics card and power supply. As well, I have tried one stick of ram and them swapped it with the other.

Each component successfully powers up on its own, such that they light-up and their fans work.

My two screens are connected via DVI input.

Any suggestions to this problem are much appreciated.

Thanks.

All I can suggest before returning it for a different board is disconnect the SSD & see if it will go the BIOS setup.
