Drivers

What Is a Driver?

A driver is a program that controls a device such as a printer, mouse, or keyboard. All devices require a driver program.

A driver acts like a translator between the device and any other programs that use the device. Each device has its own set of specialized commands that only its driver recognizes.

Dell ships your computer to you with required drivers already installed—no further installation or configuration is needed.

NOTICE: The Drivers and Utilities CD may contain drivers for operating systems that are not on your computer. Ensure that you are installing software appropriate for your operating system.

Many drivers, such as the keyboard driver, come with your Microsoft® Windows® operating system. You may need to install drivers if you:

Identifying Drivers

If you experience a problem with any device, identify whether the driver is the source of your problem and, if necessary, update the driver.

  1. Click the Start button and click Control Panel.

  2. Under Pick a Category, click Performance and Maintenance.

  3. Click System.

  4. In the System Properties window, click the Hardware tab.

  5. Click Device Manager.

  6. Scroll down the list to see if any device has an exclamation point (a yellow circle with a [!]) on the device icon.

If an exclamation point is next to the device name, you may need to reinstall the driver or install a new driver.

Reinstalling Drivers and Utilities

NOTICE: The Dell Support website at support.dell.com and the optional Drivers and Utilities CD provide approved drivers for Dell™ computers. If you install drivers obtained from other sources, your computer might not work correctly.

Using Windows XP Device Driver Rollback

If a problem occurs on your computer after you install or update a driver, use Windows XP Device Driver Rollback to replace the driver with the previously installed version.

  1. Click the Start button and click Control Panel.

  2. Under Pick a Category, click Performance and Maintenance.

  3. Click System.

  4. In the System Properties window, click the Hardware tab.

  5. Click Device Manager.

  6. Right-click the device for which the new driver was installed and click Properties.

  7. Click the Drivers tab.

  8. Click Roll Back Driver.

If Device Driver Rollback does not resolve the problem, then use System Restore to return your computer to the operating state that existed before you installed the new driver.

Using the Optional Drivers and Utilities CD

NOTE: The Drivers and Utilities CD may be optional and may not ship with your computer.

If using Device Driver Rollback or System Restore does not resolve the problem, then reinstall the driver from the Drivers and Utilities CD (also known as the ResourceCD).

  1. Save and close any open files, and exit any open programs.

  2. Insert the Drivers and Utilities CD.

In most cases, the CD starts running automatically. If it does not, start Windows Explorer, click your CD drive directory to display the CD contents, and then double-click the autorcd.exe file. The first time that you run the CD, it might prompt you to install setup files. Click OK, and follow the instructions on the screen to continue.

  1. From the Language drop-down menu in the toolbar, select your preferred language for the driver or utility (if available). A welcome screen appears.

  2. Click Next.

The CD automatically scans your hardware to detect drivers and utilities used by your computer.

  1. After the CD completes the hardware scan, you can also detect other drivers and utilities. Under Search Criteria, select the appropriate categories from the System Model, Operating System, and Topic drop-down menus.

A link or links appear(s) for the specific drivers and utilities used by your computer.

  1. Click the link of a specific driver or utility to display information about the driver or utility that you want to install.

  2. Click the Install button (if present) to begin installing the driver or utility. At the welcome screen, follow the screen prompts to complete the installation.

If no Install button is present, automatic installation is not an option. For installation instructions, either see the appropriate instructions in the following subsections, or click Extract, follow the extracting instructions, and then read the readme file.

If instructed to navigate to the driver files, click the CD directory on the driver information window to display the files associated with that driver.

  1. After extracting the driver files to your hard drive as described in the previous section, click the Start button and right-click My Computer on the desktop.

  2. Click Properties.

  3. Click the Hardware tab and click Device Manager.

  4. Double-click the type of device for which you are installing the driver (for example, Modems or Infrared devices).

  5. Double-click the name of the device for which you are installing the driver.

  6. Click the Driver tab and click Update Driver.

  7. Click Install from a list or specific location (Advanced) and click Next.

  8. Click Browse and browse to the location to which you previously extracted the driver files.

  9. When the name of the appropriate driver appears, click Next.

  10. Click Finish and restart your computer.
