disconnect ur battery over the usual period of time the car is left.on reconnection if the car battery is fine its an electrical fault.have u the code for ur stereo???!!! if its still hard to start check ur battery connections r clean and shiny also check ur main earth strap from ur engine/g,box to ur car body is clean and tight.get ur battery checked.then id worry about the starter motor, this can be checked at a decent garage or autoelectricians.a cheap cure for a electrical fault that drains the battery is to buy a battery cut off .
