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 media 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: •
Upgrade your operating system.
Reinstall your operating system.
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. Microsoft® Windows® XP

Restoring Your Operating System You can restore your operating system in the following ways: Reinstalling Software
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.
Dell PC Restore by Symantec (available in Windows XP) and Dell Factory Image Restore (available in Windows Vista) returns your hard drive to the operating state it was in when you purchased the computer. Both permanently delete all data on the hard drive and remove any programs installed after you received the computer. Use Dell PC Restore or Dell Factory Image Restore only if System Restore did not resolve your operating system problem.
If you received an Operating System disc with your computer, you can use it to restore your operating system. However, using the Operating System disc also deletes all data on the hard drive. Use the disc only if System Restore did not resolve your operating system problem.
Using Microsoft Windows System Restore The Windows operating systems provide a System Restore option which allows 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. Any changes that System Restore makes to your computer are completely reversible. 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 apply if you set your Dell™ computer to the Windows Classic view. Starting System Restore

To see if System Restore is enabled: 1 Click Start→ Control Panel→ Performance and Maintenance→ System. Reinstalling Software
2 Click the System Restore tab and ensure that Turn off System Restore is unchecked.
Using Dell™ PC Restore and Dell Factory Image Restore NOTICE: Using Dell PC Restore or Dell Factory Image Restore permanently deletes all data on the hard drive and removes any programs or drivers installed after you received your computer. If possible, back up the data before using these options. Use PC Restore or Dell Factory Image Restore only if System Restore did not resolve your operating system problem. NOTE: Dell PC Restore by Symantec and Dell Factory Image Restore may not be available in certain countries or on certain computers. Use Dell PC Restore (Windows XP) or Dell Factory Image Restore (Windows Vista) only as the last method to restore your operating system. These options restore your hard drive to the operating state it was in when you purchased the computer. Any programs or files added since you received your computer—including data files—are permanently deleted from the hard drive. Data files include documents, spreadsheets, e-mail messages, digital photos, music files, and so on. If possible, back up all data before using PC Restore or Factory Image Restore.
