Ahh, as any beeps would help determine if a particular component isn't working. It may be worth doing a bit of trial and error by disconnecting different parts of the PC until the problem disappears.

If you've made sure that everything is disconnected, then yes. So, your best bet is to either buy a new motherboard, or if it's a "budget" PC, replace the PC.
