NOTE: After the computer completes POST, all four lights turn off before booting to the operating system.
Light Pattern
Problem Description
Suggested Resolution
The computer is in a normal off condition or a possible pre-BIOS failure has occurred.
The diagnostic lights are not lit after the system successfully boots to the operating system.
Plug the computer into a working electrical outlet (see Power Problems).
If the problem persists, contact Dell (see Contacting Dell).
If the problem persists, contact Dell (see Contacting Dell).
Memory modules are detected, but a memory failure has occurred.
If two or more memory modules are installed, remove the modules (see Removing Memory), then reinstall one module (see Installing Memory) and restart the computer. If the computer starts normally, continue to install additional memory modules (one at a time) until you have identified a faulty module or reinstalled all modules without error.
If available, install working memory of the same type into your computer (see Installing Memory).
If the problem persists, contact Dell (see Contacting Dell).
If available, install a working graphics card into your computer.
If the problem persists, contact Dell (see Contacting Dell).
A possible floppy drive or hard drive failure has occurred.
Reseat all power and data cables.
A possible USB failure has occurred.
Reinstall all USB devices and check all cable connections.
No memory modules are detected.
If two or more memory modules are installed, remove the modules (see Removing Memory), then reinstall one module (see Installing Memory) and restart the computer. If the computer starts normally, continue to install additional memory modules (one at a time) until you have identified a faulty module or reinstalled all modules without error.
If available, install working memory of the same type into your computer (see Installing Memory).
If the problem persists, contact Dell (see Contacting Dell).
Memory modules are detected, but a memory configuration or compatibility error has occurred.
Ensure that no special requirements for memory module/connector placement exist (see Memory).
Ensure that the memory you are using is supported by your computer (see Memory).
If the problem persists, contact Dell (see Contacting Dell).
A possible expansion card failure has occurred.
Determine if a conflict exists by removing an expansion card (not a graphics card) and restarting the computer (see Removing PCI and PCI Express Cards).
If the problem persists, reinstall the card you removed, then remove a different card and restart the computer.
Repeat this process for each expansion card installed. If the computer starts normally, troubleshoot the last card removed from the computer for resource conflicts (see Troubleshooting Software and Hardware Problems).
If the problem persists, contact Dell (see Contacting Dell).
Another failure has occurred.
Ensure that all hard drive and optical drive cables are properly connected to the system board (see System Board Components).
If there is an error message on the screen identifying a problem with a device (such as the floppy drive or hard drive), check the device to make sure it is functioning properly.
If the operating system is attempting to boot from a device (such as the floppy drive or optical drive), check system setup (see System Setup) to ensure the boot sequence is correct for the devices installed on your computer.
If the problem persists, contact Dell (see Contacting Dell).

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 installedno 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.
Windows XP:
Click Start and clickControl Panel.
Under Pick a Category, click Performance and Maintenance®System®Hardware®Device
Manager.
Scroll down the list of devices and check for an exclamation point (a circle with a [!]) next to the
device name.
If an exclamation point appears next to the device name, you may need to reinstall the driver or install a new driver (see Drivers).
NOTE: The User Account Control window may appear. If you are an administrator on the computer, click Continue; otherwise, contact your administrator to continue.
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
NOTICE: The Dell Support website at support.dell.com and your Drivers and Utilities media provide approved drivers for Dell computers. If you install drivers obtained from other sources, your computer might not work correctly.
Using Windows Device Driver Rollback
If a problem occurs on your computer after you install or update a driver, use Windows Device Driver Rollback to replace the driver with the previously installed version.
Windows XP:
Click Start and click Control Panel.
Under Pick a Category®Performance and Maintenance®System® System Properties®Hardware®Device Manager.
Right-click the device for which the new driver was installed, then click Properties.
NOTE: The User Account Control window may appear. If you are an administrator on the computer, click Continue; otherwise, contact your administrator to enter the Device Manager.
Right-click the device for which the new driver was installed and click Properties.
Click Drivers and 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 driver.
Using the Drivers and Utilities Media
If using Device Driver Rollback or System Restore does not resolve the problem, then reinstall the driver from the Drivers and Utilities media.
With the Windows desktop displayed, insert the Drivers and Utilities media.
If this is your first time to use the Drivers and Utilities media, go to step 2. If not, go to step 5.

Restoring Your Operating System
You can restore your operating system in the following ways:
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) restore 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.
