did the radio work before you jumpstarted your car. also do your intermintient wipers work properly. because most people often jump start a car from another running car. this is VERY bad to do. the problem is that the alternator is not designed to power a starter. most alternators can only put out about 110-150 amps but the starter uses more like 600-700 amps so it needs a good battery. the problem is that the alternator will kick out on the good car and then start back up at the exact same time as the car that is getting a boast. this causes a voltage problem and can some times take out computer boards. i had this happen to me a few years ago and ended up geting my stereo and a few other computer boards replaced.
