This usually results in plugging into the wrong port. After you turned on the switch on the back of the computer and then press the power up front, is there any light turned on or fans spinning? If yes, make sure to connect your monitor to the ports on your graphic card not motherboard. Display ports on your motherboard have been disabled to ensure the best video quality. The graphic card supports only DVI, HDMI, or DP(Display port) connections. If your monitor uses VGA only, you will need to get an adapter in order for your monitor to work properly with the computer.
