Pops, that's good.
I've had one or two incidents like this with hastily marketed hardware whose drivers break an otherwise stable Windows set-up. If your Version of Windows (like NT4, 2000 or XP) is one that uses Service Packs, it can help to restore health if you install/re-install the latest Service Pack.
I've got so used to the problem that when installing new hardware I now go straight to the manufacturer's Support Site to see if there are any recent drivers. The latest success doing this was with D-Link Wireless cards. Might be worth trying with Logitech.
Don't bother with the iron; doesn't work.
