Reinstalling Base System Device driver -- please HELP!
My Dell Inspiron 1521 laptop's built-in microphone doesn't work anymore after I installed Window 7.
I followed suggestions to uninstall the Audio device driver and to reinstall.
I uninstalled the Audio device driver and now my "Base System Device" doesn't have a driver. I troubleshoot and try to let Windows fix the missing driver problem but it failed.
Problems found
Base System Device doesn't have a driver (not fixed)
Base System Device doesn't have a driver (not fixed)
Hardware changes might not have been detected (Detected)
How can I get my Base System Device drivers?
Many Thanks...Mimi
