Sounds Like You Have A Voltage Drain, That Is Something Is On Or Grounded In The Car. To Test This Buy A Test Light At Parts House. Rermove The Negetive Cable From Battery, Leaving The Positive Cable Attached To The Battery. Connect Test Light Between Negetive Cable And Negative Battery Terminal: If Light Comes On You Have Something On Or Grounded. Remove The Bulb From Hood Light First ( The On That Lights Up When You Open Engine Compartment--HOOD }. Turn Off Ignition When And If You Find The Problem The Light Will Go Out. This Is The Best Way To Find Your Problem. PLEASE NOTE ++++++++ If The Light Don`t Come On. Your Battery Is Probably Bad. In Fact Go Have The Battery Tested First !!!! Then Replace If It Is Weak Or Bad. If That Don`t Work Try The Things Above. HOPE THIS ISN`T TOO MANY THINGS. GOOD LUCK --Try look for a fuse. There should be a Fuse that connects the Battery to Alternator. It by be burn out
u might need a new starter

The computer only resets when the battery is removed. The alternator just charges the battery, so if the battery is left connected when the alternator is replaced, the computer should not reset.
Then either something is on draining the battery or the battery has a dead cell draining all the rest and must be replaced.
Have you had the alternator tested? Often a bad internal diode can drain the alternator overnight.

Something is on draining your battery overnight. Any light or any relay. It can also be your battery has a dead cell draining it overnight.

While the car is running the alternator should be recharging the battery faster than stereo can drain it. I suspect you either have a problem with the alternator or its time to get your battery replaced. Until you get it fixed, if you don't turn on the radio, it wont drain your battery :) If it is a high power model, it needs to be wired directly to the battery.
If the battery is brand-new and I would suspect either the alternator is defective or you have a lightbulb somewhere on the vehicle that is pulling power from the battery. It can also be a relay that is stuck.

Need more info... How old is it? Do you drive short distances? Does it sit around not driven a lot? Check for a short, bad alternator, or fried battery. If you take the car to an alternator shop, they can usually tell you for free if it's the battery or the alternator.
