New motherboard, "no signal detected"

[TreaclePod]

So, I just replaced the motherboard in my pc as the old motherboard had died. I got everything installed, I connected a power cord and everything looked fine. When I turned on the pc i discovered that the monitor was displaying a "no signal detected" message. I have a NVIDIA GTX970, an AMD FX8350 and my motherboard doesn't have any on board graphics. Just to clarify, the pc does boot up, the graphics card seems to be working - fans turn on, led lights up. I have tried different monitors with different input/outputs and all off them give "no signal detected".

Is this a BIOS problem? How do I get to the BIOS if I can't connect to a monitor? Or is this a problem with my graphics card?

I am simply stumped and would appreciate any help. Thanks.

It's not a BIOS prob. What connections did you use to the monitor?

If you use VGA to DVI or HDMI you need an active adapter
