New rig with completely blank screen

[teeeeer]

Hey guys.

Today I was putting together a computer for my mother and I came across a few problems. When I boot everything turns on for a split second then the computer will power on again but with a completely blank screen. Can someone help?

I tried using different motherboards etc. 

Everything thing is new besides RAM and psu

Is the monitor on? Did you plug the monitor in to the graphics card if you have one?

[Deletive]

what are your CPU, motherboard and GPU?

I tried using the gpu and the motherboard graphics and the monitors are brand new

Motherboard: ASRock B85m pro3

CPU: intel core i3-4160

Go off onboard graphics then, after setting up your OS and stuff, plug the GPU into the PCI slot (still boot with display cable plugged into motherboard) and install the drivers. You should have a small-ish box to do everything from on screen, but once you install the GPU drivers, you should be fine.

I can't boot or anything. I don't even get a bios screen.

Do you have a motherboard speaker you can use?
