Arduino UNO R3 Help Please

joshreynolds1982:
In the device manager there is not anything there resembling arduino uno or an object that has a yellow triangle like usual. So there is nothing I can point to it. When the usb connecting tone sounds over and over the device manager flickers but does not give me anything that I can point to those drivers.

I see, so the most probable thing is the 8u2 is dead or not properly configured. Search for instructions to set it in DFU mode to see if is alive :smiley:
