Not dumb at all. But if you do a clean installation of Vista, then it will wipe everything extraneous off your hard drive. The crapware goes away. You will have to reinstall the programs you want, and any personal data. After the installation any drivers that need to be updated should be available from the OEM website.'s
Just Google "Vista Clean Install" and you'll find a wide variety of how-to instructions.
Hope that helps.
