Thank you so much for your responses. My intintion is to replace bothe supplies as you guys recommend. The reason I want to to just replace the 5v for now is to make sure that things will startup with the 5v replaced. I have had so much bad luck with the machine I want to make sure there's nothing else going on before I spend a lot of time on a problem that's just hiding underlying issues. Again thanks very much.
