Assuming that you have zero power to anything, not even dash lights, and assuming your starter won't turn due to no power try taking off your battery cables and leaning them with a hard tooth brush and coke. Be sure to inspect you battery cables and make sure you have good ground connection. May be time to replace some cables or terminals. Need more details to help with your problem.
More than likely it's a bad starter or bad connection going to the starter, weather it be starter end or battery end. Check both
