Computer Parts These are the parts we dissected::

Computer Parts These are the parts we dissected: Side Cover Drive Cables Case Wires Power Supply Fan Network Card BIOS Dial Up Network Card Sound Card RAM Floppy Disk Drive CD ROM Drive Hard Drive Motherboard

And off comes the cover…:

And off comes the cover… Our first step was to snap the cover off. The side panels were easy to snap off.

Get out the toolbox!:

Get out the toolbox! Next we unscrewed the Power Supply. We had to rotate the Power Supply up in order to get to the screw. Then we unplugged it and snapped it out.

Connections! Now we disconnected the drive cables. These are ribbon cables which connect the hard drive and disc drive to the motherboard.

One more…:

One more… We removed any wires that were left.

Onto the PCI cards:

Onto the PCI cards Next we unscrewed and removed the PCI cards. The first one was the Network Card.

Wait…there’s more!:

Wait…there’s more! We unscrewed and took out the BIOS.

...And the Sound Card too:

...And the Sound Card too Like other PCI cards, the sound card was easily removed. First, we removed any screws holding the card in place. Then, we carefully pulled the card from its PCI slot.

Motherboard with Empty PCI Slots:

Next, we took out the RAM.:

Next, we took out the RAM. There was only one RAM chip on our motherboard. We simply pushed down on the clips and slid the RAM out of its slot.

Onto the drives...:

Onto the drives... First, we slid the floppy disk drive out of its compartment. This simply required pushing down on the clip mechanism holding it in place.

Now the big one...:

Now the big one... We unscrewed the motherboard. The motherboard still contained the chipset and the CPU.

Time to put it back together!:

Time to put it back together! To put our PC back together, we reversed our disassembly process.

The Motherboard:

The Motherboard The Motherboard was put into the computer case and secured with the screws. The chipset remained attached to the motherboard


RAM Next the RAM was snapped into its slot on the Motherboard. This was only on RAM chip that needed to be added to the Motherboard.

The Floppy Drive:

The Floppy Drive The floppy drive was slipped into the drive casing and clipped into place.

The CD ROM Drive:

The CD ROM Drive The CD ROM Drive, also slipped into the drive case and was secured by clips.

Onto the PCI cards PCI Cards and PCI SLots :

Onto the PCI cards PCI Cards and PCI SLots The Sound card was the next component that was placed back into the computer. This PCI card snapped into the PCI slot and secured with a screw to the computer case

PCI Cards and PCI Slot:

PC I Cards and PCI Slot Additional PCI cards were also snapped into the PCI slots and secured to the computer case with a screw.

Network Card:

Network Card The Network card was snapped into the PCI slot and secured to the computer case with one screw.


BIOS The final PCI card is placed into its PCI slot. It snaps into place and again it is secured by a screw. This PCI card contains the BIOS.

External View of the PCI Cards:

External View of the PCI Cards This is a photo of the external view of the computer when all of the PCI cards were replaced back into the computer.

The FAN:

The FAN The fan was placed back into the computer. It was secured in place by four screws. The power supply of the fan was then plugged into the Motherboard.

Hard Drive :

Hard Drive The Hard drive was replaced by snapping into place and securing it to the case with a screw.

Ribbon Cables:

Ribbon Cables Then the ribbon cables that connect the hard drive, disc drive and the motherboard were reconnected .

Power supply:

Power supply The power supply it the last component to be replaced. The power supply was snap into its casing and was secured by four screws to the casing. Then the power supply with the casing was rotated down into the computer case and it was plugged in.

Computer Case:
