My wife's PC runs on XP (SP2). A box has appeared, top left. It is headed "Autoplay" and shows an icon of a torch waving from side to side. Seems to indicate it is searching for something? This runs for a few seconds then disappears. After 5 - 10 seconds it runs again and is continuous. There is nothing in either of the CD /DVD trays and I have not instaled anything recently. It is driving her nuts, which in turn is driving me nuts. Any suggestions please?
