If the boards are under powered then they might freeze up, what he meens by boost up.
Look at the actual board where your power connectors and other stuff is screwed onto, not the game board the other one, there should be a green LED on the board, now, there's a knob that you can turn with a flat head screw driver. Now, use a multi meter and set the multi meter to the 9v option, put the multi meter's thingys one on red termenal, and the other on one black termanal (on the board where the knob is) if the system is under powered it should read about 4.8 volt, now slowly turn the knob with a flat screw driver, slowly to the right, untill you get a reading on the multi meter of about 5.5 volt.
Unplug the power cord at the wall, now remove power cord on the actual game board, and test the power there aswell, the power there would drop there, it should read about 5.3 / 5.4 volt (I think) leave it in that range, but if it reads 5.5 volt, which i doubt it will, leave it as is.
I tried explaining best i could, hope it helps and hope you understand.
