HI Ellie112001, my name is Rick and I work with the Windows Outreach Team and would like to help. Sometimes updating drivers leads to problems that can be frustrating. I am providing a link to the Vista Help and How-to webpage regarding hardware driver updates. There are tips and instructions on getting the correct driver, or “roll back” a freshly installed driver.
Tips for fixing common driver problems - Windows Vista Help . Another option you could try would be to go to your PC manufactures support page and download the latest drivers from their site.
Good luck, Rick
