strange noise when starting up

In the past couple of days I've noticed a rattling-type noise when starting my car up (2000 Sunfire). It starts and stays running just fine. We just had a bout of really cold, snowy weather and I haven't driven it in about two weeks. The last time I got my oil changed, I was told that I have a crack in my serpentine belt. Think this could be the cause of the strange noise? I hear no squeaks though when the car is idling. Thanks for any suggestions.

Loose starter bolts?

Loose starter bolts?

Thanks for the suggestion. Is this something that can be fixed without going to a shop?

just see if the 2 bolts on the starter are loose. If they are just tighten them
