  1. Turn the computer off and wait 10 seconds
  2. Turn the computer back on and start slowly tapping the [F8] key
  3. A black screen with white text will come up
  4. Use the Up|Down arrow keys to select "Repair Your Computer" and press [Enter]
  5. On the next screen it'll ask which type of keyboard, click the Next> button
  6. If you have a Windows password, type it in on the next screen and click OK
  7. Click the "Startup Repair" link and follow the onscreen instructions
    (If it gives you the option of doing a Windows "System Restore" you might want to try it)
  8. When it's done, cross your fingers and click Restart
