1995 BMW 740 CAR WON'T START

I HAVE A 1995 740IL, WHILE I WAS DRIVING MY BATTERY INDICATOR LIGHT CAME ON (THIS WAS THE FIRST TIME THIS HAD HAPPENED) AND THEN THE CAR DIED TWO MILES LATER. MY BATTERY WAS 7 PLUS YEARS OLD SO I REPLACED IT WITH A NEW ONE AND NOW IT WON'T START. MY CAR MAKES NO NOISE AT ALL. I JUMP STARTED THE STARTER AND I HEARD THE MOTOR OF THE STARTER, SO THE STARTER IS GOOD PLUS I HAD A DIAGNOSTIC TEST FOUR MONTHS AGO AND EVERYTHING WAS GOOD. IS IT MY EWS, DOES IT NEED TO BE RESET?
