Today, a personal computer can be found in almost every home, but despite this, few people understand how the system unit works. Not everyone will be able to answer fairly simple questions: what is under the cover of the case or how everything is connected and what is it for. Using this article, you will not only answer these questions, but you will also be able to disassemble the system unit yourself.
Instructions
Step 1
First, it is necessary not only to turn off the computer, but also to disconnect it from the power supply, otherwise, in some models of cases, standby power of 5 volts will still be supplied.
Step 2
You should start with the side cover of the case, it can be opened and closed in various ways (it all depends on the model and manufacturer). It happens that manufacturers do not install any locks, latches or toggle switches, in which case you just need to unscrew all the screws on the back of the case (sometimes the side covers open together with the top one). Then we slightly push the walls back to pull out the fasteners. At the same time, on some models, special mechanisms can be installed, for example, latches, which are easy to open - just pull them gently towards you. There are also simple locks, then special keys must be included with the computer case.
Step 3
So, after you've removed the side cover, the first thing that catches your eye is the large board attached to the opposite wall. This is the most important part in any computer - the motherboard. The following elements are attached to it: a video card (without which it is impossible to watch a movie), RAM (responsible for the speed of information processing), a processor (computer brain) and various buses from DVD / CD drives, hard drives, and so on.
Step 4
Closer to the center is the processor hidden under the cooling heatsink and fan. Next to it, a little to the right, there is one or several boards inserted into special slots - this is RAM. A power supply is installed on top of the case, from which there are many wires. The second largest board is the video card, which is also attached to the motherboard.
Step 5
After examining the location of the main components of the computer, you can start disassembling it. The main thing is to do everything with the utmost care, without using force. First, turn off the power supply, pull out all connectors from the motherboard, drives and other devices. Next, unscrewing the screws, we take out the power supply. Then you can move on to the RAM and the video card: by pressing on the special fasteners on each side of the board, carefully remove it.
Step 6
Moving on to the processor, first remove the fan. Then, gently shaking the heatsink, disconnect it from the processor. There is a special handle on the socket, pulling which you release the processor (remember its location relative to the handle).
Step 7
Now you can disconnect the drive and hard drive. Disconnect the busbars from the devices themselves, then unscrew all the screws securing these elements to the case. Take out everything that you unscrewed.
Step 8
The assembly must be carried out in the reverse order, be extremely careful and do not confuse anything.
