Thanks for the quick reply John. I connected just the Arduino and the light came on but did not give me a signal saying it had connected to the laptop but did not shut it down. Then connected the ramps did not shut down the laptop but still no signal saying it is connected. Turned on the power supply and connected to the laptop did not shut it down Arduino light is on but nothing from the ramps I went and checked the com port and nothing is show up tried another usb cable still nothing. I only know enough to get myself in trouble but there should be some communication right? I have attached pictures of the Arduino and ramps.
