1998 Chevy Blazer Won't Start

When I turn the key over to start the vehicle, the clock resets to 1:00, the back latch clicks and the car kind of makes a grinding sound but not like a churn as if it wanted to start. I don't know if it is just a dying battery or if it would be something else but my car will not start at all. Any ideas?

Tighten battery connections make sure they are not corroded, test battery, all basics.
