Undo Last System Restore

• First, try restoring your Windows system to the last known good configuration. To do this, restart your computer and listen for a single beep. When you hear the beep, press the F8 key repeatedly until a menu of choices is displayed. Select the option to use the last known configuration, and hit "Enter". Windows will attempt to restore itself the last point in time that your computer was working properly. If it's successful, everything should be working and no further troubleshooting is necessary.
  
  

Use a Different Restore Point

• If restoring to the last known good configuration fails to revive your computer, you may have other restore points saved. If so, restoring your system to one of these points may work. Restart your computer again, and when you hear the single beep, press "F8" repeatedly until the menu displays. This time, select the option to boot into safe mode.
  
  Once Windows is started, select "Start", "All Programs", "Accessories", and "System Tools". Select "System Restore". Choose "Restore to an earlier time" and select "Next". Select the restore point you wish to try from the calendar that is displayed, and Windows will attempt to return all operating system and registry files to that point.
  
  

Use Windows Recovery Console

• If neither of these options solves the problem, you can also try to repair your system using the Windows Recovery Console. Insert your Windows installation CD and restart your computer. When it starts, it will attempt to begin system setup. When prompted, select option "R" to start the recovery console. The recovery console will attempt to repair the corrupted boot record of your operating system.
  
  

Reinstall Windows

• If these steps don't get your system up and running, you may have to reinstall Windows. Unfortunately, this results in formatting your hard drive. You will lose all data and program installations, but you should be able to regain the use of your computer. To do this, you'll need your Windows CD and the installation CDs of your programs and hardware. Insert your Windows CD and reboot. Follow the prompts to reinstall Windows. Once Windows has completed installation, reinstall your programs by inserting the program CD and following the on-screen instructions. .
