Answer 2

First, check your battery cables, make sure they are clean and well connected. If they look gunked up, try and remove the clamps and clean them in a mixture of baking soda and water, then dry them well and put them back on.

Then, check the battery itself, if it is more than 3 years old, it should be replaced. Any basic service center, even Wal-mart, can check this.

Last, have someone check the serpentine belt. This is the belt which runs across several parts of your engine and spins when the engine is running.

If all these things are ok, then have the alternator checked.
