I got a brand new motherboard and psu yesterday. Everything powers up fine, no beeps, but there is nothing being output to my monitor - just a black "no signal" screen.

I have tried:
- removing gpu and connecting monitor to onboard.
- swapped between hdmi and vga.
- using a different monitor and testing monitor on my laptop.
- using only 1 ram or 2 ram in all optional slot configurations with different sticks.
- switching gpu to different pci slot.
- cleaning and reseating cpu.
- reset cmos battery.
- tried a different gpu.

None of these had any change at all.

Specs:
Motherboard: asrock z75 pro3 (brand new)
Psu: corsair 750w (brand new)
Gpu: gtx 660
Cpu: i5 3570k
Ram: 16GB DDR3

Gpu and cpu both were working completely fine with my old motherboard yesterday.
 
Just returning the new motherboard. Went back to my old motherboard and everything worked just fine again so I can only assume something is wrong with it.
