think i have fixed it. disconected the connector carrying the 5 volts from the driver board.measured voltage at 5.03v decided to bump it up a tad to 5.1v,because i could.simple turn of a pot.reconnect and test all day long ie games and attract for 12 hours.seems good.no more resets.

Have i done the right thing,or will this cause problems further down the track?
