It Luks Like Either Theres An Incompatibility Issue with Your Proccesor And Motherboard OR try Dissconnecting all cables from behind the rig except the power cable and video cable, then see if it works OR Lastly Try Getting Your Motherboard Replaced If Its Still On The Warranty.
PS:If You Overclocked Your Proccessor, try returing its values to its orignal state in the bios.
