Ran my car just fine then all of the sudden when i went into a store for no more than five mins and came back out my car just did one click when i turned the key, tried to jump it and yet still didnt turn over but my windows and cd player still work so i know i have power... what do i do

Seems like the battery is ok, and has enough power. Have the starter solenoid and the starter motor checked. usually, if you hear a clicking, the solenoid is working alright, so the problem is probably relater to the starter motor itself. Make sure that the shifter is SOLIDLY in the park position, jiggle it a couple of times to make sure it isnt slightly out of park.
