Continuous beeping sound on a new build

Contiuous beeping like that is usually a sign that the cpu is not working. If you have the motherboards user manual it should tell you what the beep codes are. It could also be the ram so you can remove the ram sticks and reseat them and if it still beeps then take and remove them all and put in one and try it then try each one at a time in the slot closest to the cpu socket.
