Solving Hardware Installation Problems

You may need to reconfigure the computer when you add or remove hardware,
such as an additional drive or expansion card. If you install a plug and play device,
Windows automatically recognizes the device and configures the computer. If
you install a non–plug and play device, you must reconfigure the computer after
completing installation of the new hardware. In Windows, use the Add Hardware
Wizard and follow the instructions that appear on the screen.
