does it have a beep sound? if yes, try to reseat your component, ex: graphic card/memory/processor..
if not perhaps you should try change your card, and try, can it show something on screen, if no, there could be many factors, could be the board, or the processor or the memory.. if the boot goes fine, maybe you can try to plug your card in other system / computer..
if both OK, the perhaps it's compatibility issue, try to ask your vendor..
hope it helps..
