Ensure that your computer and attached devices are turned off. If your computer and
attached devices did not automatically turn off when you shut down your computer, turn
them off now.
NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall jack.
Disconnect any telephone or telecommunication lines from the computer.
Disconnect your computer and all attached devices from their electrical outlets, and then
press the power button to ground the system board.

Move the hinge arms to the closed position.
Align the two clips on the inside of the front door with the two hinge arms.
Press inward on the front door until it clips to both hinge arms.
Memory
You can increase your computer memory by installing memory modules on the system board.
Your computer supports DDR2 memory. For additional information on the type of memory supported by your computer, see the memory specifications.
DDR2 Memory Overview
If you are installing two DDR2 memory modules, you should install the modules as a pair, with matched memory size and speed. If the DDR2 memory modules are not installed in a matched pair, the computer will continue to operate, but with a slight reduction in performance. If you install a mixed pair of DDR2 400-MHz (PC2-3200) and DDR2 533-MHz (PC2-4300) memory, the modules function at the slowest speed installed. See the label on the module to determine the module's capacity.
NOTE: Always install DDR2 memory modules in the order indicated on the system board.
NOTICE: Do not install ECC memory modules.
The recommended memory configuration is a pair of matched memory modules installed in DIMM connectors 1 and 2.
NOTE: Memory purchased from Dell is covered under your computer warranty.
NOTICE: If you remove your original memory modules from the computer during a memory upgrade, keep them separate from any new modules that you may have, even if you purchased the new modules from Dell. If possible, do not pair an original memory module with a new memory module. Otherwise, your computer may not start properly. You should install your original memory modules as a pair in DIMM connectors 1 and 2.
Addressing Memory With 4-GB Configurations
Your computer supports a maximum of 4 GB of memory when you use two 2-GB DIMMs. Current operating systems, such as Microsoft® Windows® XP, can only use a maximum of 4 GB of address space; however, the amount of memory available to the operating system is less than 4 GB. Certain components within the computer require address space in the 4-GB range. Any address space reserved for these components cannot be used by computer memory.
Installing Memory
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.
Lay the computer on its side so that the system board is on the bottom of the inside of the
computer.
Press out the securing clip at each end of the memory module connector.
Align the notch on the bottom of the module with the crossbar in the connector.
NOTICE: To avoid damage to the memory module, press the module straight down into the connector while you apply equal force to each end of the module.
Insert the module into the connector until the module snaps into position.
If you insert the module correctly, the securing clips snap into the cutouts at each end of the module.
Close the computer cover.
NOTICE: To connect a network cable, first plug the cable into the network device and then plug it into the computer.
Connect your computer and devices to electrical outlets, and turn them on.
Right-click the My Computer icon and click Properties.
Click the General tab.
To verify that the memory is installed correctly, check the amount of memory (RAM) listed.

Your Dell™ computer provides the following slots for PCI Express cards:
One PCI Express x16 card slot
One PCI Express x1 card slot
NOTE: The slots for the PCI Express x16 and PCI Express x1 cards are half-height slots.
PCI Express Cards
Your computer supports one PCI Express x16 card and one PCI Express x1 card.
If you are installing or replacing a PCI Express card, follow the procedures in the next section. If you are removing but not replacing a card, see "Removing a PCI Express Card."
If you are replacing a card, remove the current driver for the card from the operating system.
If you are installing a new card, remove the filler bracket to create a card-slot opening. Then
continue with step 4.
If you are replacing a card that is already installed in the computer, remove the card.
If necessary, disconnect any cables connected to the card. Gently pull the securing tab, grasp the card by its top corners, and then ease it out of its connector.
Prepare the card for installation.
See the documentation that came with the card for information on configuring the card, making internal connections, or otherwise customizing it for your computer.
CAUTION: Some network adapters automatically start the computer when they are connected to a network. To guard against electrical shock, be sure to unplug your computer from its electrical outlet before installing any cards.
If you are installing the card into the x16 card connector, position the card so the securing slot
is aligned with the securing tab, and gently pull the securing tab.
Place the card in the connector and press down firmly. Ensure that the card is fully seated in
the slot.
Ensure that:
The tops of all cards and filler brackets are flush with the alignment bar.
The notch in the top of the card or filler bracket fits around the alignment guide.
Secure the card(s) in the computer.
NOTICE: Do not route card cables over or behind the cards. Cables routed over the cards can prevent the computer cover from closing properly or cause damage to the equipment.
Connect any cables that should be attached to the card.
See the documentation that came with the card for information about the card's cable connections.
NOTICE: To connect a network cable, first plug the cable into the network device and then plug it into the computer.
Close the computer cover, reconnect the computer and devices to electrical outlets, and then
turn them on.
Install any drivers required for the card as described in the card documentation.
If necessary, disconnect any cables connected to the card.
Gently pull back the securing tab, grasp the card by its top corners, and then ease it out of its
connector.
If you are removing the card permanently, install a filler bracket in the empty card-slot
opening.
If you need a filler bracket, see "Contacting Dell" in your Owner's Manual.
NOTE: Installing filler brackets over empty card-slot openings is necessary to maintain FCC certification of the computer. The brackets also keep dust and dirt out of your computer.
NOTICE: To connect a network cable, first plug the cable into the network device and then plug it into the computer.
Close the computer cover, reconnect the computer and devices to electrical outlets, and then
turn them on.
Remove the card's driver from the operating system.
