New Graphics Card but Monitors won't respond

So recently I got a new Asus R9 270X. I installed it into my PC as an upgrade from Intel Graphics 4000. I inserted it into the first PCI-E slot, I plugged the power cables in and I connected the monitors. But when I first booted it my monitors didn't respond they just went black as if the computer wasn't even on. Can someone please help me?

unplug the card and update the drivers, then plug it back in... assuming everything lit up correctly

Ok I'll try thanks.


that work? sounded like a driver issue....
