Something sounds off with the IDE, with no Arduino connected to computer the Port submenu should still show COM1. Also as your computer recognizes the USB but it doesn't show up in the list makes me think something is up with the IDE itself. The only issue I've seen is the com shows up and can be selected but when uploading it'll say Com X not found. That's what happens with the erasing issue I spoke about. You might have to try uninstalling the Arduino IDE and re-installing it. The IDE does have a lot of quirks and quite a few people have had to do this.
