hey everyone, so i recently i tried building a whole pc for the first time and its goin all well until i tried to hook it up to a moniter, the pc turns on fine all the fans work but nothing shows up on the moniter and the power button on it flashes, i am using a p55v LE motherboard and a nvidia 220 gt graphics card. there is nothing wrong with the moniter since it works fine with another pc and i tried it with another moniter aswell. 
 
please help!!
