why does my l298n motor driver beep?

Question

My l298n motor driver that is hooked up to my rpi beeps and the motors don't move when i run code how ever i worked before a changed the power pack however now it doesn't work with that one either.

Here's my code:

# import curses
import curses

# Get the curses window, turn off echoing of keyboard to screen, turn on
# instant (no waiting) key response, and use special values for cursor keys
screen = curses.initscr()
curses.noecho() 
curses.cbreak()
screen.keypad(True)

try:
        while True:   
            char = screen.getch()
            if char == ord('q'):
                break
            elif char == curses.KEY_UP:
                print "up"
            elif char == curses.KEY_DOWN:
                print "down"
            elif char == curses.KEY_RIGHT:
                print "right"
            elif char == curses.KEY_LEFT:
                print "left"
            elif char == 10:
                print "stop"    

finally:
    #Close down curses properly, inc turn echo back on!
    curses.nocbreak(); screen.keypad(0); curses.echo()
    curses.endwin()

And my setup: photos will be up later sorry i gotta stop using google drive
