|NOTE: The Drivers and Utilities CD and the Operating System CD are optional and may not ship with your computer.|
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 installedno 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:
If you experience a problem with any device, identify whether the driver is the source of your problem and, if necessary, update the driver.
If an exclamation point is next to the device name, you may need to reinstall the driver or install a new driver.
|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.|
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.
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.
|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).
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.
The CD automatically scans your hardware to detect drivers and utilities used by your computer.
A link or links appear(s) for the specific drivers and utilities used by your computer.
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.
|NOTE: If you are reinstalling an infrared sensor driver, you must first enable the infrared sensor in system setup (see Enabling the Infrared Sensor) before continuing with the driver installation.|
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:
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.
|NOTICE: Make regular backups of your data files. System Restore does not monitor your data files or recover them.|
|NOTE: The procedures in this document were written for the Windows default view, so they may not work if you set your Dell computer to the Windows Classic view.|
|NOTICE: Before you restore the computer to an earlier operating state, save and close any open files and exit any open programs. Do not alter, open, or delete any files or programs until the system restoration is complete.|
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.
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.
The Restoration Complete screen appears after System Restore finishes collecting data and then the computer restarts.
To change the restore point, you can either repeat the steps using a different restore point, or you can undo the restoration.
|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.|
The System Restore screen appears and the computer restarts.

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.

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.
