New build not booting

Hi guys

I've just received some new gear;
MSI 990FXA GD65 motherboard
AMD Phenom II x4 975
Corsair Vengeance DDR3 1600mhz

I've installed these, with my old Geforce GTX285 and it isn't booting.
I know the graphics card(s) are fine, I've tried 2 in there.
The problem I'm having is that it isn't booting, showing no display. It does this for 20 or so seconds and then I get 1 really short high pitched beep.

I've tried the following;
Disconnected HDD's - Same error
Disconnect graphics - Continuous beeps
Disconnect ram - Continuous beeps.

The motherboard is showing all 8 lights on the cpu phase power (If that means anything)
And the power supply is fine, been using it the last 4 months in my old machine.

Any ideas?
