You probably have a low five volts. The ticking isn't actually the DMD, it's the boot sound that's normally there but you don't remember hearing because it normally only lasts for a second. Your game keeps rebooting because the watchdog senses the 5v are low and resets the game over and over. Kahr.us has a little dohicky that goes in your mpu plug and will fix this. Just type kahr.us into your address bar, and look for the WPC power fix daughterboard.
