Using the Selective Startup option, you can turn services and startup programs on or off individually to see if the problem occurs the next time you restart your computer. If you select a check box in System Configuration, the service or startup program will run when you restart Windows. If the check box is cleared, the service or startup program won't run when you restart the computer.

Follow this procedure to use the process of elimination to identify the problem.
•Open System Configuration by clicking the Start button.
•Click Control Panel
•Click System and Security
•Click Administrative Tools
•Double-click System Configuration. If you're prompted for an administrator password or confirmation; type the password or provide confirmation.
•Click the General tab
•Click Selective startup
•Clear the Load system services and the Load startup items check box then select the load system services check box
•Click OK, and then click Restart

•Identify the system service that is causing the problem
•Click the Services tab

•Select the check box for the first service that is listed
•Restart the computer

To identify the system service that is causing the problem
•Click the Services tab,
