New motherboard and cpu NO DISPLAY
So recently I just got a new motherboard and cpu. When I plug in everything (or at least I think every thing) all the computer fans seem to work perfectly but the monitor doesnt budge or (No Display). I have already checked the ram,motherboard,gpu,psu,and the monitor and they all work. I have now been without a computer for a week and it is very frustrating. Please help ASAP as it would be greatly appreciated.
