Yup! That's what we're telling you. If you are not comfortable rolling back your audio or graphics drivers, and you've also never done a System Restore before, you should consider paying a Computer Pro in your locale to do it for you.
If you bork your Windows, how do you expect to repair it? And the most important issue is, if you read my Troubleshooting Guide link, we strongly suggest that you
FIRST BACKUP ALL OF YOUR PERSONAL DATA TO EXTERNAL MEDIA! THIS WOULD INCLUDE YOUR LIBRARY FOLDERS FOR DOCUMENTS, PHOTOS, MUSIC, VIDEOS, AND ANY SAVED E-MAILS OR ATTACHMENTS IN ORDER TO AVOID IRRETRIEVABLE DATA LOSS!!!
No offense, but a lot of people here on so focused in on fixing their immediate problem, they don't take proper backup precautions, and they don't even respond to a direct question as to whether or not they have done this step.
They are often embarrassed when we ask the question, or simply have never done a backup in their lives and don't know how to do it--and so are afraid to address the issue or even ask the simple question of needing help to do so!
If you don't have good backups to external media, playing around with driver settings, driver rollbacks, driver uninstallation/reinstallation, and performing System Restore on your computer all have the potential for disaster--think of it as a tightrope walker 100ft. up working without a net!
Doing the repairs suggested without an external backup is like working on your computer without a net!
If you make 1 mistake, you could get killed or at the least permanently crippled.
'nuff said! It's your computer. Just trying to let you know what you are in for if you aren't sure what you are doing.
