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 the programs that use the device. Each device has its own set of specialized commands that only its driver recognizes.
Many drivers such as the keyboard driver come with your Microsoft®Windows®operating system. You may need to install drivers if:
l You upgrade your operating system. l You reinstall your operating system. l You connect or install a new device.
NOTICE: Before restoring the computer to an earlier operating state, save and close all open files and close all open programs. Do not alter, open, or
delete any files or programs until the system restoration is complete.
NOTICE: Before undoing the last system restore, save and close all open files and close all open programs. Do not alter, open, or delete any files or
programs until the system restoration is complete.
If you experience a problem with any device, perform the steps in the following sections to identify whether the driver is the source of your problem and to update the driver, if necessary.
Identifying Drivers
1. Click the Start button and click Control Panel.
2. In the Control Panel window, under Pick a Category, click Performance and Maintenance.
3. In the Performance and Maintenance window, click System.
4. In the System Properties screen, click the Hardware tab.
5. Click Device Manager.
6. In the Device Manager window, 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
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 or to replace the driver with the previously installed version.
To use Device Driver Rollback:
1. Click the Start button and click Control Panel.
2. In the Control Panel window, under Pick a Category, click Performance and Maintenance.
3. In the Performance and Maintenance window, click System.
4. In the System Properties screen, click the Hardware tab.
5. Click Device Manager.
6. In the Device Manager window, right-click the device for which the new driver was installed, and then 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 operating system to the operating state it was in before you installed the new driver.
Using the Dell Dimension ResourceCD
If using Device Driver Rollback or System Restore does not resolve the problem, then reinstall the driver from the Dell Dimension ResourceCD:
1. With the Windows desktop displayed, insert the ResourceCD into the CD or DVD drive.
If this is your first time to use the ResourceCD, go to step 2. If not, go to step 5.
2. When the ResourceCD installation program starts, follow the prompts on the screen.
3. When the InstallShield Wizard Complete window appears, remove the ResourceCD and click Finish to restart the computer.
4. When you see the Windows desktop, reinsert the ResourceCD into the CD or DVD drive.
5. At the Welcome Dell System Owner screen, click Next.
A message stating that the ResourceCD is detecting hardware in your computer appears.
The drivers that are used by your computer are automatically displayed in the My DriversThe ResourceCD has identified these components in your system window.
6. Click the driver that you want to reinstall and follow the instructions on the screen.
If a particular driver is not listed, then that driver is not required by your operating system.
Resolving Software and Hardware Incompatibilities
Microsoft®Windows®XP IRQ conflicts occur if a device either is not detected during the operating system setup or is detected but incorrectly configured.
To check for conflicts on a computer running Windows XP:
NOTICE: The Dell Support website and your Dell Dimension ResourceCDprovideapproveddriversforDell™computers.Ifyouinstalldriversobtained
from other sources, your computer might not work correctly.
HINT: The ResourceCD displays drivers only for hardware that came on your computer. If you installed additional hardware, those drivers might not be
displayed by the ResourceCD. If those drivers are not displayed, exit the ResourceCD program. For drivers information, see the documentation that came with that product.
1. Click the Start button, and then click Control Panel.
2. Click Performance and Maintenance, and then click System.
3. Click the Hardware tab, and then click Device Manager.
4. In the Device Manager list, check for conflicts with the other devices.
Conflicts are indicated by a yellow exclamation point (!) beside the conflicting device or a red X if the device has been disabled.
5. Double-click any conflicting device listed to bring up the Properties window to determine what needs to be reconfigured or removed from the Device Manager.
Resolve these conflicts before checking specific devices.
6. Double-click the malfunctioning device type in the Device Manager list.
7. Double-click the icon for the specific device in the expanded list.
The Properties window appears.
8. Resolve any IRQ conflicts, as described in step5.
If an IRQ conflict exists, the Device status area in the Properties window reports the cards or devices that share the device's IRQ.
You can also use the Windows XP Hardware Troubleshooter:
2. Click Help and Support.
3. Type hardware troubleshooter in the Search field, and then click the arrow to start the search.
4. Click Hardware Troubleshooter in the Search Results list.
5. In the Hardware Troubleshooter list, click I need to resolve a hardware conflict on my computer.
