Computer performance degrades over time. One of the reasons for this is the accumulation of a large amount of dust by the internal devices of the system unit. To get to all circuit boards and controllers, you need to disassemble it, i.e. remove the side walls and dismantle all devices.

Instructions
Step 1
First of all, you need to power off the computer. What does it mean? Unplug all plugs from the system unit, monitor, speakers and other peripheral devices. It is also recommended to turn the system unit with the back side facing you and turn the switch on the power supply to the “O” position.
Step 2
Now you need to open one of the side walls of the system unit. Take a close look at the fasteners that the developers have been supplying to the sidewalls lately. If no such fasteners were found, then this is a classic sample. Take a Phillips screwdriver in your hands and unscrew all connecting screws (unscrew in a counterclockwise direction).
Step 3
Pull out the side wall. Press it against the body of the box and pull it out with a sharp movement. There are also combined systems - in addition to screws, latches with locks are located on the side walls. As a rule, such system units are purchased to order.
Step 4
Now your attention is provided with a picture of all internal devices. The largest board in a computer device is the motherboard or system board. Devices such as RAM, processor, video adapter, hard drives, and CD / DVD drive are connected to the connectors on this board.
Step 5
Before removing all devices from the connectors of the system unit, you must pull out the power cables from the connectors of all devices, including the motherboard. Turn the back side of the system unit towards you and while holding the power supply, unscrew all the screws.
Step 6
Then take out the RAM. To do this, simultaneously clamp both stops, which are located at the edges of the installed strip.
Step 7
Next, remove all coolers (fans). First of all, you need to disconnect the power wires and only then proceed to unscrewing the screws. The fan on the processor has a special mounting method, usually with a slide. Do this carefully as This cooler is much more expensive than other fans in the system unit, therefore, much more money will be required to replace it.
Step 8
Removing audio and video adapters is quite simple: remove one screw with a screwdriver and press on the stop located on the side of the board. Now you just have to dismantle the hard drives, drives, and the motherboard itself. Unscrew all screws and take out the above-mentioned devices.
