CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a
card by its edges or by its metal mounting bracket. Hold a component such as a processor by its edges, not by
its pins.
NOTICE: Only a certified service technician should perform repairs on your computer. Damage due to servicing
that is not authorized by Dell is not covered by your warranty.
NOTICE: When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself.
Some cables have a connector with locking tabs; if you are disconnecting this type of cable, press in on the locking
tabs before you disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any
connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.
To avoid damaging the computer, perform the following steps before you begin working inside the
computer.
1
Turn off your computer.
NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the
network wall jack.

Setting Up Your Computer
CAUTION: Before performing any of the procedures in this section, follow the safety instructions in Product
Information Guide.
NOTICE: If your computer has an expansion card installed (such as a modem card), connect the appropriate cable
to the card, not to the connector on the back panel.
NOTICE: To help allow the computer to maintain proper operating temperature, ensure that you do not place the
computer too close to a wall or other storage compartment that might prevent air circulation around the chassis.
See your Product Information Guide for more information.

NOTE: Before you install any devices or software that did not ship with your computer, read the documentation
that came with the device or software, or contact the vendor to verify that the device or software is compatible
with your computer and operating system.
You must complete all the steps to properly set up your computer. See the appropriate figures that follow
the instructions.
NOTICE: Do not attempt to operate a PS/2 mouse and a USB mouse simultaneously.
1
Connect the keyboard and mouse.
NOTICE: Do not connect a modem cable to the network adapter connector. Voltage from telephone
communications can cause damage to the network adapter
2
Connect the modem or network cable.
Insert the network cable, not the telephone line, into the network connector. If you have an optional
modem, connect the telephone line to the modem.
3
Connect the monitor.
Align and gently insert the monitor cable to avoid bending connector pins. Tighten the thumbscrews
on the cable connectors.
NOTE: Some monitors have the video connector underneath the back of the screen. See the documentation
that came with your monitor for its connector locations.
4
Connect the speakers.
5
Connect power cables to the computer, monitor, and devices and connect the other ends of the power
cables to electrical outlets.
NOTICE: To avoid damaging a computer with a manual voltage-selection switch, set the switch for the voltage that
most closely matches the AC power available in your location.
NOTICE: In Japan, the voltage selection switch must be set to the 115-V position even though the AC power
available in Japan is 100 V.
6
Verify that the voltage selection switch is set correctly for your location.
Your computer has a manual voltage-selection switch. Computers with a voltage selection switch on
the back panel must be manually set to operate at the correct operating voltage.

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product
Information Guide.
To help you troubleshoot a problem, your computer has four lights labeled "1," "2," "3," and "4" on the
front or back panel. The lights can be "off" or green. When the computer starts normally, the patterns or
codes on the lights change as the boot process completes. If the POST portion of system boot completes
successfully, all four lights display solid green for a short time, and then turn off.
If the computer malfunctions during the POST process, the pattern displayed on the LEDs may help
identify where in the process the computer halted. If the computer malfunctions after a successful
POST, the diagnostic lights do not indicate the cause of the problem.

Beep Codes
Your computer might emit a series of beeps during start-up if the monitor cannot display errors or
problems. This series of beeps, called a beep code, identifies a problem. One possible beep code
(code 1 3-1) consists of one beep, a burst of three beeps, and then one beep. This beep code tells you
that the computer encountered a memory 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" on page 6.

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" on page 54).
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, including the drivers required if your computer has a RAID
controller.
Reinstalling Windows XP
NOTICE: You must use Windows XP Service Pack 1 or later when you reinstall Windows XP.
NOTICE: Before performing the installation, back up all data files on your primary hard drive. For conventional
hard drive configurations, the primary hard drive is the first drive detected by the computer.
To reinstall Windows XP, you need the following items:
