This can be caused by one of the following

1 Monitor not connected properly.

2 Faulty hardware

Verify that the monitor is properly connected in the back of the monitor as well as to the back of the computer If the monitor appears to be connected properly, verify that a cable is not loose by disconnecting all cables that can be disconnected in the back of the monitor (generally the data cable cannot be disconnected) Next, disconnect the data cable connected to the back of the computer and then reconnect the cable When connecting the cable in the back of the computer ensure the cable connection is tight, check also that all the pins are straight Most Computers will also have screw ends that the cable can be screwed in, to hold the connector in place Do the same for the Keyboard.

it could be Faulty hardware, if the connections appear to be correct, it is likely that either the monitor or the computer video card is faulty, or maybe just loose A simple test is to connect a different monitor to your computer Or connect your monitor to a different computer

Also make sure that all the wires on your new motherboard are connected properly If they are then you might have a faulty motherboard, in which case you must contact the manufacturer.

Hope this helps Good Luck!
