Have you looked in "computer" tab from the start orb. If it's there right click on it, select properties, in pop up select hardware tab and see if it's listed. If it is it should tell what it is. Next, click the tools tab at top in computer from orb, select folder options, in popup select view tab - scroll down to the hidden files and folders, select either show or don't show. Next, check in your bios for hardware tab and see what is listed. It could be picking up on a controller from the mobo for a device to add on like a floppy drive. If that's the case just disable it in the bios.
