Won't even click!!

I have a 1995 Aurora. Started just fine until Saturday, when it just wouldn't even click. Power is fine. I turn key to the on position and radio and dash lights come on. I go to start position and nothing. Power is off while in start position. The starter doesn't click at all. No noise. Any clues? On other cars when I have had starter issues there seems to be some trouble signs or at least I get noise. Please help!!!!!!!
