98 Silhouette Won't Start

I have a 1998 Silhouette that today won't start. I have had no problems with it until this morning.

I turn the key and just a click - all the dash lights are on and there seems to be power but nothing else but a click.

I took the battery out thinking it might be dead... charged it fully, and then replaced. Still nothing but a click when I turn the key?

Any ideas where I should start looking?

Thanks!

Its a little late but I can only think of the battery or the starter. What was the problem??
