I have a Carnevil that will not boot up unless you have the power supply 5 volts turned up to 5.6 volts. At 5.6 volts it will just reboot and reboot. If you go to 5.7 volts it will boot up and run longer. Anything under 5.6 volts and it will not boot. Does anyone know what could cause this. I have put in a brand new swithching power supply and it still does the same thing. Thanks
