Computer won't post

[Nestik]

I know, I know, I shouldn't be talking about post problems, but I'm not sure what to do! This is my first build and I'm really stressed out! When I turned it on for the very first time I got two beeps, then nothing happened. Tried with 1 stick of RAM instead of the four that I put in; got absolutely nothing. HELP!

Build:
CPU: AMD FX-8320
Motherboard: Asus M5A78L-M USB3
Graphics card: XFX Radeon 7970
Power Supply: Corsair GS700
RAM: Corsair Vengeance 4x4GB (2x(2x4))
Case: Corsair 300D
SSHD: Seagate 500GB

Try starting up with no sticks of RAM. This will ensure that it's not the motherboard or the RAM DIMM slots that are bad.
