Now that you have just cleaned
the hard disk, you will pass to the great spring-cleaning
of your computer.
You cannot imagine what one
finds in a computer even if it is not old and has the
clean air: large sheep of dust to the pieces of paper,
ashes of cigarettes, residues of nibbling.... I do not
speak to you about the people who have a dog or a cat!!
There is not great a deal
to have for cleaning a PC well : a bomb with neutral air
(to avoid all bad contact between the electronic components),
of a bomb of cleaning for screen and keyboard, of a wet
rag and a screwdriver.
When you want to clean your
PC or a peripheral, always think of disconnecting the

central processing unit.
Befor opening the UC, it is necessary to think of two
disconnect all the cables connecting the PC and to think
of discharging the static electricity which you accumulated
by touching a metal object or while carrying an anti-static
bracelet to avoid making damage in the electronic components.
Once the opened side panel, unscrew the readers of CD,
DVD etc.... and to disconnect tablecloths. Leave their
compartments and note the direction of connections of
the tablecloths not to be mistaken in any tonic. Certain
people also dare to remove the hard disk, for my part,
I it you will not advise.
Once the removed peripherals, remove the most possible
dust then pass a blow of bomb of air but not too meadows
to avoid damaging the components. Pass well between the
mother chart and the case, like in all the small recesses.
Do not touch with your fingers the printed circuits, the
grease of the fingers could deteriorate the transfer of
Think of well vacuum-cleaning the radiators and the heat
sinks fixed on the transistors of power and commutation.
Sometimes the power supply units are difficult to dismount,
go ahead gently and note all the contacts if you must
disconnect from wire to be able well to give them. It
is very important to eliminate dust well from the ventilators
like on the wings, me I use a cotton bud to remove all
dust. Do not forget especially that of the processor.
Do not forget also the power supply unit. If necessary,
remove it and pass a blow of bomb towards the interior
then towards outside to remove the maximum of dust.
When you finished, use a wet rag and wipe interior and
outside of the case. To prevent that dust does not return
too quickly in the UC, think of placing a filter of the
same type as the filters which prevent dust from arising
from the vacuum cleaners or the range hoods on the level
of the air intake (the small ones perforate behind the
tower). Of the same ridges for the block of alimentaion.
Attention not the butcher because the processor, which
needs much to be refreshed, risk of completion to burn!!!!
Before closing again the UC, give all the peripherals
to their places. Profit in to make a check-up of the screws
to avoid unwanted noise which can leave the UC.
Arrange well the tablecloths and the wire, if it is the
disorder, use clips for good to gather them.
Close again and replug all the cables. Start the PC and
check that all is normal.
Here is, your central processing unit is very clean!
The keyboard is a trap with dust. It accumulates a layer
of grease to the wire of time and must, also, cleaned
being. The keyboards perdurent they are well maintained.
Like measures preventive, it is preferable of to abstain
to eat and of drinking close to the keyboard: if you reverse
liquid, you are likely to roast the contacts...
Do not dismount the keyboard, it will be very hard all
to go up and that especially will make it inoperative.
For certain keyboard, you can remove the keys upwards.
Go ahead gently with a screwdriver with head punt and
remove them and wash them a-by-a for you point out the
place of the keys. Otherwise, disconnect it and turn over
it to reduce dust and the particles. Pass a blow of bomb
to air between the keys to remove the remainder. Use the
bomb for keyboard or a product cleaning with a good rag
to remove the filth.
Sometimes, you can pass a blow of vacuum cleaner on the
keyboard in order to eliminate dust.
The mouse is the peripheral easiest to clean, the manufacturer
very envisaged: turn over the mouse and turn the ring
retaining the ball in the direction reverses needles of
a watch. Leave the ball its housing and clean it with
a wet rag which does not become fluffy, let dry it. Withdraw
all the dust which is inside the mouse. Look at the three
serrated rollers which make it possible the ball to give
information. They will be dustier if you do not use a
carpet. Remove the filth with alcohol with 90° and
cotton buds. Do not use ustensils out of steel, style
screwdriver, pins..., to avoid damaging them.
For the mice with serrated rollers, unscrew the screws
which are in lower part then raise the higher part by
blocking at the same time the serrated roller by a finger.
Clean it with a cotton bud by making it turn. To avoid
a too fast clogging of the mouse, use a carpet of mouse
having a surface closes and which does not hang the remains
of dust. If you can choose the aspect of the ball, choose
a brilliant ball, and having a firm surface. The matt
balls retain more dust and involve it inside the mouse.
Best is to choose an optical mouse: there is no ball.
Moreover they are of an incredible precision as well as
great freedom of movement.
There are two types of screens used for the moment: cathode
ray tube monitors and monitors with liquid crystals (LCD).
For the first model, it is rather simple. The extinguished
screen, you can pass from the bomb to clean the screens
or quite simply a soft rag soaked with product with panes.
Clean the case well in front of, behind and on the with
dimensions ones. Because of its magnetism and its static
electricity, l’ screen attracts much dust. Moreover,
you ensure that the grids d’ ventilation are well
released and that nothing block them.
If you are obliged to open the monitor, will know that
great attention should be paid.
It is a very important point. It is necessary to be very
careful for the power supply of the cathode ray tube,
it can send to you a value of 30.000 voltes in the fingers...
Will also know that even if the monitor were stored in
an attic for 6 months, there can very well be still current.
Lastly, for the LCD, It is a little the reverse of the
cathode ray tube monitors. Use only upkeeping products
for data processing. Do not scrape the screen and do not
support too strong bus these screens are much more fragile.
Moreover, never open a LCD, it is extremely fragile and
For the other peripherals :
Clean the heads via the pilot of the printer. Go in the
Control panel and choose the Imprimante icon. In the mitre
Services or Cleaning, click on line up the heads and clean
of the cartridges.
For the manual cleaning of the heads, open the cap, remove
them and pass a cotton bud with water on its face for
removing the remainders well. Make in the same way for
the supports of the cartridges like on the site of the
cartridges to the stop. Clean well the rollers of drive
of paper with a wet rag.
The cleaning of the pane must be often made. Take a rag
soaked with cleaning with pane not abrasive and remove
the traces well. Do not pulverize directly on the pane
cleaning it. For outside, proceed as on the monitor.
Wait until all is quite dry and carry out a Classification
test to see whether there are still traces. For those
which have courage of it, deposit some extra-light oil
drops on the metal axis the length whose moves the luminous
of CD-ROM or DVD.
It is really not necessary to open such readers completely,
except only people who know each other there.
To clean them, it is enough that they remain open when
Windows stops. If it is not the case, use the end of a
trombone and pass it in the small hole in frontage of
the reader to force left the plate, then draw gently towards
Now, make slip the end of the straw of the bomb with air
into the reader and clean well. For the lens, you can
use CD of cleaning (15 € approximately).
Once the open mask or leaves the slit, passes the end
of the straw of the bomb to air in the reader and cleans
You can also use a vacuum cleaner with a special end and
aspire slightly; interior of l’ unit. Another method
to clean the heads is to get a case of cleaning of disk
drive. While following the directives, you can clean the
heads while inserting the diskette of cleaning simply.

Check only if the screws are well fixed to remove with
