[help] starting problem

my car -- 91 Nissan sentra 1.6L auto
I encountered a starting problem at 5:00PM this afternoon. I turned the key, there were no start and no sound, and all of the indicators on the panal were on. Actually I used the car today from 10:00am to 1:00PM and I visited several stores so I started the car several times and there was no problem at all. It is highly appreciated if you can give some suggestion about this problem.

battery. first, try moving the battery wires, push them down and stuff. if it doesnt work, then i suggest you go to autozone to check if your battery is dead. maybe it can be your alternator who ust messed up.
