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.
Many drivers, such as the keyboard driver, come with your Microsoft

Windows
®
operating system. You may need to install drivers if you:
l Upgrade your operating system.
l Reinstall your operating system.
l Connect or install a new device.
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 Start® Control Panel® System.
2. Click Hardware® Device Manager.
3. 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 (see Reinstalling Drivers and Utilities).
Reinstalling Drivers and Utilities
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 Start® Control Panel® System.
2. Click Hardware® Device Manager.
3. Right-click the device for which the new driver was installed and click Properties.
4. Click Drivers® 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 (see Using Microsoft Windows XP System Restore).
NOTICE: The optional 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.
NOTICE: The Dell Support website at support.dell.com and your Drivers and UtilitiesCDprovideapproveddriversforDell™computers.Ifyouinstall
drivers obtained from other sources, your computer might not work correctly.
Using the Drivers and Utilities CD
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.
3. From the Language drop-down menu in the toolbar, select your preferred language for the driver or utility (if available). A welcome screen appears.
4. Click Next.
The CD automatically scans your hardware to detect drivers and utilities used by your computer.
5. 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.
6. Click the link of a specific driver or utility to display information about the driver or utility that you want to install.
7. Click Install (if present) to begin installing the driver or utility. At the welcome screen, follow the screen prompts to complete the installation.
If Install is not 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.
Manually Reinstalling Drivers
1. After extracting the driver files to your hard drive as described in the previous section, right-click My Computer on the Windows desktop® Properties®
Hardware® Device Manager.
2. Double-click the type of device for which you are installing the driver (for example, Modems or Infrared devices).
3. Double-click the name of the device for which you are installing the driver.
4. Click Driver® Update Driver.
5. Click Install from a list or specific location (Advanced)® Next.
6. Click Browse and browse to the location to which you previously copied the driver files.
7. When the name of the appropriate driver appears, click Next® Finish and restart your computer.
Software and Hardware Incompatibilities
If a device is either not detected during the operating system setup or is detected but incorrectly configured, you can use the Hardware Troubleshooter to
resolve the incompatibility.
1. Click Start® Help and Support.
2. Type hardware troubleshooter in the Search field and click the arrow to start the search.
3. Click Hardware Troubleshooter® I need to resolve a hardware conflict on my computer® Next.
NOTE: The Drivers and Utilities CD may be optional and may not ship with your computer.

Sensor) before continuing with the driver installation.
Restoring Your Operating System
You can restore your operating system in the following ways:
l Microsoft
®
Windows
®
XP System Restore returns your computer to an earlier operating state without affecting data files. Use System Restore as the
first solution for restoring your operating system and preserving data files.
l If you received an Operating System CD with your computer, you can use it to restore your operating system. However, using the Operating System CD
also deletes all data on the hard drive. Use the CD only if System Restore did not resolve your operating system problem.
Using Microsoft Windows XP System Restore
The Microsoft Windows XP operating system provides System Restore to allow you to return your computer to an earlier operating state (without affecting
data files) if changes to the hardware, software, or other system settings have left the computer in an undesirable operating state. See the Windows Help
and Support Center for information on using System Restore. To access the Windows Help and Support Center, see Windows Help and Support Center.
Creating a Restore Point
1. Click Start® Help and Support.
2. Click the task for System Restore.
3. Follow the instructions on the screen.
Restoring the Computer to an Earlier Operating State
If problems occur after you install a device driver, use Device Driver Rollback (see Using Windows XP Device Driver Rollback) to resolve the problem. If that is
unsuccessful, then use System Restore.
1. Click Start® All Programs® Accessories® System Tools® System Restore.
2. Ensure that Restore my computer to an earlier time is selected and click Next.
3. Click a calendar date to which you want to restore your computer.
The Select a Restore Point screen provides a calendar that allows you to see and select restore points. All calendar dates with available restore points
appear in boldface type.
4. Select a restore point and click Next.
If a calendar date has only one restore point, then that restore point is automatically selected. If two or more restore points are available, click the
restore point that you prefer.
5. Click Next.
The Restoration Complete screen appears after System Restore finishes collecting data and then the computer restarts.
6. After the computer restarts, click OK.
To change the restore point, you can either repeat the steps using a different restore point, or you can undo the restoration.
Undoing the Last System Restore
1. Click Start® All Programs® Accessories® System Tools® System Restore.
2. Click Undo my last restoration® Next.
NOTICE: Make regular backups of your data files. System Restore does not monitor your data files or recover them.

NOTICE: Before you undo the last system restore, save and close all open files and exit any open programs. Do not alter, open, or delete any files or
programs until the system restoration is complete.
Enabling System Restore
If you reinstall Windows XP with less than 200 MB of free hard-disk space available, System Restore is automatically disabled. To see if System Restore is
enabled:
1. Click Start® Control Panel® Performance and Maintenance® System® System Restore.
2. Ensure that Turn off System Restore is unchecked.
Using the Operating System CD
Before You Begin
If you are considering reinstalling the Windows XP operating system to correct a problem with a newly installed driver, first try using Windows XP Device Driver
Rollback (see Using Windows XP Device Driver Rollback). If Device Driver Rollback does not resolve the problem, then use System Restore to return your
operating system to the operating state it was in before you installed the new device driver (see Using Microsoft Windows XP System Restore).
To reinstall Windows XP, you need the following items:
l Dell™Operating System CD
l Dell Drivers and Utilities CD
Reinstalling Windows XP
The reinstallation process can take 1 to 2 hours to complete. After you reinstall the operating system, you must also reinstall the device drivers, virus
protection program, and other software.

NOTE: The Drivers and Utilities CD contains drivers that were installed during assembly of the computer. Use the Drivers and Utilities CD to load any
required drivers. Depending on the region from where you ordered your computer, or whether you requested the CDs, the Drivers and Utilities CD and
