it has power sooo whats up

Still may not be enough voltage to run starter motor. Still could be a weak battery or poor cable conection at batter post. Radio and lights take much less voltage than starter motor...but you starter mortor could fail in same manner at the age of your car. Reccomend you have someone test battery and starting system.
could be starter but ck cables for being clean and tight,very common
