The videocard only outputs digital, so if your monitor is connected to VGA using an adapter or something, that could be a problem. The motherboard has integrated video outputs, double check that you are connected to the videocard and not one of the motherboard outputs. That motherboard has more than one pci-ex x16 slot, make sure the card is in the one designed for videocards. That videocard needs an 8 pin pci-ex connector from the power supply. Make sure the cable you connect to it from your power supply is the right one. Sometimes people try to connect the two 4 pin ATX connectors to it.
