What is the device manager showing for the com: ports? Port assignment is a function of the O/S. I am not that familiar with the Arduino but recall it did have USB and wonder if you could disable its serial port. I have a little Atom computer about that size that I communicate with it using TightVNC to control things.
I mucked with serial since we set jumpers and it has always been a pain. At least they also dumped parallel -- that was a real bag of worms. Software control by the O/S only makes for more troubles.
I'd pull the Arduino. View the device manager. attach it. view again.
That may show you the conflict. Also look at the spec to see if the Arduino set a control port at an offset that may cause the conflict.
