How to disassemble a computer and clean it
Such a need arises, for example, for cleaning the PC from dust or replacing thermal grease on heating elements, such as: processor, video card, motherboard chips (north and south bridges). Also, it may be necessary to replace some block, or upgrade, - upgrade the equipment to a more modern one. Sometimes you can replace something without removing the motherboard, but sometimes this is necessary for convenience and the probability of damage to the element when bending during installation. When the card is removed, it is possible to support it from the back side, preventing such bends.Practically on all models of cases there are special recesses on the covers for which you should pull back. This will release the latches and the sidewalls will easily come off.
Removing the coverYes, to get inside the system, you need to remove one, and sometimes two, the two side covers of the case. How to do it? Behind the system unit there are specific screws, two for each cover. Any small screwdriver, be it a cross or straight, twist it.
Preparation.If you decided to completely disassemble your PC then first You must disconnect the cords. There are a lot of them and they are of different appearance. Usually there is a latch on the side of the connector, which you need to release by pressing. If this is not done, you can break the connector, which can lead to the replacement of the motherboard. Therefore, you need to be careful, and before removing, carefully inspect the junction.
Dismantling the video card.When the plugs are removed, proceed to dismantle the video card. Usually it is large and when you unscrew the fastening screw that fixes it on the case, the card will freely hang from side to side, which can damage the connector on the motherboard. Therefore, release the fastening latch, which is located on the right, bottom of the video card .To do this, feel it with your finger and push the lever down. At the same time, the card will be half out of the nest. Then just pull it with your fingers, without damaging its elements.
Removing the motherboard.There are screws around the perimeter of the board Carefully unscrew and fold it into a separate box. For convenience, we put the system unit on its side, and unscrew the screws one by one with a magnetised screwdriver. After, we check whether they are all dismantled. If so, it will move freely when the board moves.

Remove dust. When everything is disassembled, you can gently vacuum the sistemnik yourself.
The boards, such as: motherboard, video card, RAM, CPU cooler and video card can be blown out with an enema pear. A very useful thing in such cases, especially if you have animals that are littered everywhere with their wool.You will see the shreds of this wool in your PC.
In general, you can blow everything that can direct a point air flow , for example, a compressor. Just a “pear” is in every home. You can wipe the boards with a cotton swab dipped in triple cologne. And the smell will be and the dust will go away.
In hard-to-reach places use a match or a toothpick with cotton wound on it. But you need not to overdo it, not to make great efforts not to "tear down" some sort of capacitor or resistor. Be gentle with your faithful iron friend. You also need to assemble the device, only in the reverse order. All connectors should be in place. Difficulties can be with the wires of the front panel. But using pre-made photos of problems should not be. On this perhaps all. Good luck with your PC.
