Dust and debris are your PC’s worst enemy. As
dust builds up, caking your fans and components, your PC finds it harder and
harder to breathe and stay cool. This puts an increased strain on your
hardware, leading to a shorter lifespan. Regular cleaning can significantly
increase the lifespan of your computer, and if you stay on top of it, cleaning
will only take a few minutes each time. See Step 1 below to get started.

Cleaning the Case
1
Setup an area where you can blow dust. You will be using compressed air
and a vacuum to remove the majority of the dust from the inside of your
computer, so set up an area that you can blow dust out without worrying about
getting other things dirty. A garage or workbench is a good choice, or you can
go outside if it’s a dry day.

Try to set up a table so that you can easily access the
computer without having to bend over or set it on the ground.

Gather your supplies. You will need a Phillips screwdriver, compressed
air (either in a can or via a compressor), a small vacuum that can fit in
narrow crevices, a toothbrush, and 99% isopropyl alcohol.

Do not use an old vacuum with a metal tip, as these are
usually poorly grounded and can damage your components. The best option is a
newer handheld vacuum with an extendable plastic hose.

Power down the computer and unplug all of the peripherals. Shut down
your computer and disconnect all of the cables on the back. Make sure that the
monitor is unplugged, and that any USB cables, Ethernet cables, speaker cables,
or anything else is unplugged as well. Flip the switch on the power supply and
then remove the power cable.

Set the computer on its side. Place the computer on its side on
your table or workbench. Make sure that the connectors on the back are laying
closest to the surface. These connectors are attached to the motherboard, and
can help you ensure that you remove the correct side panel.

Remove the side panel. Remove the screws that hold the side panel in
place. These screws can be found along the back of the computer. Most modern
cases have thumbscrews that you can remove without tools, though you may need
to use the screwdriver for older cases or thumbscrews that are too tight.

Do an initial vacuum. Depending on how long it’s been and your
environment, you could be greeted by a pretty gruesome sight. Dust has a
tendency to collect and cake on your components, and the entire inside may be
covered in a fine layer of gray. Use your vacuum cleaner to do a pass over the
interior, sucking up the large bits of dust from the components and crevices.

Be careful not to strike any of the components with the
vacuum tip as you move it across the interior. Many components inside are very
fragile, and bent pins and connectors can render your hardware useless.

Use the compressed air to blow dust out of crevices. Take your
can of compressed air or air compressor and blow out the hard to reach
crevices. Use the vacuum to help reduce the amount of dust that scatters in
puffs.

Avoid long, sustained blasts, as this will make your can

fans can make them spin faster than they are designed to, potentially damaging
them.

gently scrub the dust that remains off of the blades.

You may be able to access the fans easier if you remove
them fist. You will need to remove the screws that secure the fan to the
chassis, and then disconnect the cable that connects the fan to the
motherboard. Make sure that you note where the fan was plugged in so that you
can easily reconnect it when you’re finished cleaning.

Make sure to reattach the fan in the same direction that
it was originally installed. Fans blow in one direction, and reversing the
direction of air flow can significantly impact the cooling of your machine.
Most fans have an arrow printed on the top of the housing that indicates which
way it blows.

Remove components for deep cleaning. While a general vacuum and dusting
is usually sufficient for basic cleaning, you’ll want to remove individual
components to really get them sparkling again. Make sure that you are properlygrounded before touching any of the internal components. When
you remove the components, set them on an antistatic surface, such as wood or
rubber.

You can remove the graphics card by removing the screws
that secure it to the case, releasing the tab underneath, and then gently
pulling it straight out. You may have to disconnect power cables in order to
fully remove it. Set the graphics card on your cleaning surface and use the
brush and alcohol to remove stubborn dust.

·
Removing the hard drive and any optical drives can make
it easier to clean them, since they are often tucked away in hard-to-reach
bays. Removing these drives typically involves opening both sides of the case
so that you can reach the screws securing each side of the drive. Most optical
drives are pulled out of the front of the case after the screws have been
removed.

Removing the CPU cooler will allow you to clean out the
cracks in the heat sink, as well as brush the dust out of the fans. Heat sinks
attach in a variety of different ways, so make sure to consult your
documentation before trying to remove it. Some require you to remove a bracket
from the backside of the motherboard. If you remove the CPU cooler, you will
need to apply a new layer of thermal paste to the
CPU before reattaching it.

Dust all of the grates. Depending on your case, you may have some grates
for fans and airflow. Use your compressed air to blow out from the inside of
the case, and then run a feather duster over the grate from the outside.

over the keyboard, unplugging your keyboard first is probably a good idea. This
will help reduce the chance of electrostatic discharge damage.

outside). Run your hand over the keys while holding the keyboard upside down
and shake it while you do so. You should see lots of debris shaking out.

you’ll need to remove each of the keys so that they can be cleaned and you can
access the innards of the keyboard. Removing keys is a little tedious, but can

start washing most of the components. Anything that is just plastic can go
through the dishwasher or be hand-washed. The keys can be washed individually
by hand, or you can put them in an enclosed dishwasher basket.
