Dash Lights All Flashing on 2001 Chevrolet Impala

This has happened 2 or 3 mines in the last month. When I'm driving & stopped, ALL of the indicator & warning lights flicker on & blink for a 1-2 seconds, accompanied with a sound like a "wrong answer" buzzer on a gameshow. What in the world could cause this? Would it be something simple like a fuse going out to the dash lights?
