When I upgraded from 98 to XP, my external CD-R was no longer compatible with the OS. So I uninstalled it. But still every time I start the computer, I get a little bubble on the bottom right of the screen telling me that there are drivers installed which may cause instability so they have been stopped from loading and gives me the opportunity to link to the manfacturer's website.

The website has no options to make this device compatible, which is fine, I just want that bubble to stop popping up. Am I supposed to delete this driver, and if so, how do I do that? I've tried skimming through the driver folders but have no idea which is what.
