Case Scenario 4-1 trouble shooting graphics drivers A user asks you to troubleshoot his Windows 7 workstation, which is behaving erratically. He has recently purchased and installed a new graphics adapter, ND ever since then, he sees occasional wavy lines in the display.

To resolve the problem the computer must be restarted in safe mode, hold IF when computer restarts 2- The graphic adapter must be rolled back to a previous state then troubleshooter 3-An older driver update maybe be able to fix software problems Safe Mode Safe Mode is a troubleshooting tool used to allow the user to start computer in a limit state with only the basics running This allows user to remove or roll back drivers Windows 7 Configuration
