Yes, you have a bad Ram on the game pcb. In the manual you will see a guide for self test. There is s switch by the volume control above the coin box. If it's making those noises it's already in self test. You may find once you change the bad ram the next one in line will show up bad. Hopefully it will be an easy fix.
