Troubleshooting Hardware with the Device Manager

Windows XP works with countless different printers, scanners, digital cameras, and other devices. It does so with the help of drivers, unique software programs that help your operating system communicate with individual pieces of hardware. If your computer starts to freeze, crash, or if a hardware device stops working, you can troubleshoot the problem with the Device Manager. Device Manager shows you how the hardware on your computer is installed and configured, and how the hardware interacts with your computer's programs. You'll typically use Device Manager to check the status of your hardware and update device drivers on your computer. Advanced users who have a thorough understanding of computer hardware might also use Device Manager's diagnostic features to resolve device conflicts and change resource settings. Note You may need to be logged on as an administrator or be a member of the Administrators group in order to use some or all of the features in Device Manager. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.
