Difficulty: Moderately Easy
Step1
Enter the device command into the "config.sys" file for older Windows operating systems. These commands can define whether the device is loaded normally or if it is to be loaded into upper memory. The older operating systems gave lots of flexibility to the user as to how the drivers were loaded into memory and in what order they loaded.
Step2
Right click on "My Computer" icon on the desktop. Select "Properties." Select the Hardware tab and click on "Device Manager" to open up the window that shows all the devices connected to the computer and allows access to the drivers for these devices.
Step3
Locate the driver that you need to install either from the Internet or on a CD or other media that came with the computer from the manufacturer. Look at the Device Manager screen and find the device that has a yellow exclamation point on it indicating that there is a problem with the driver for that device.
Step4
Click the icon (right click) and select "Update Driver." Read the Hardware Setup Wizard window that opens and follow the directions carefully. When asked to have Windows find the driver select "No" and then browse to the location of the driver that you have. Let the Hardware Setup Wizard install the new driver and close the Device Manager.
