Every time you turn your computer off and Windows shuts down successfully, important system settings are saved in the registry. If a problem occurs, you can restart your computer using those settings. For example, if a new driver for your video card is causing problems, or an incorrect registry setting is preventing Windows from starting correctly, you can restart your computer using Last Known Good Configuration.
If you notice your system behaving strangely and Windows is still running, try using System Restore to return the system to an earlier point in time when things worked correctly
