Many friends spend a lot of time choosing computer configurations before installing the computer, but when it comes to the actual installation, they are at a loss and don't know where to start. This article will teach you step by step how to assemble a desktop computer.
1 Basic Hardware Components of Desktop Computers
To assemble a complete desktop computer, first start by understanding its hardware components, in order of chassis, power supply, motherboard, CPU, Memory, hard drive, monitor, keyboard and mouse. The above is the core, essential hardware. The remaining auxiliary hardware can be evaluated according to your actual situation, such as optical drives, speakers, fans, etc.
2CPU and memory purchase
As the core central processing unit, it can be based on actual needs. For example, for gaming needs, at least 4 cores should be configured, and the four-core acceleration ratio should be around 2.2 times. . This will improve the smoothness and experience of playing games. At present, CPUs belong to AMD and Intel. You can choose either one of them. Generally speaking, the bigger the memory, the better, and the faster the data processing capability. However, this still needs to be combined with CPU speed to avoid excess waste.
3 Motherboard Shopping
The brand selection of motherboards is much greater than that of CPUs. The main reason is that compared with CPUs, the manufacturing threshold of motherboards is much lower, so there are more manufacturers to choose from. Sexuality also becomes bigger. At present, the mainstream is occupied by Gigabyte, MSI, Asus, etc. If you play games, it is recommended to choose one of these brands to buy.
4 Graphics Card Selection
This component is particularly important for game players. You must not be lenient. GALAX or MSI graphics cards are worth considering, and the graphics card memory must be at least 2G.
5 Hard drive purchase
Compared with other major hardware, hard drives are a component that is updated relatively quickly. The price has been declining year by year, and it has now reached a point close to cabbage prices. What's more important is that the price of solid-state drives has gradually become acceptable to everyone, and many friends have already chosen solid-state drives to replace traditional mechanical hard drives. The most well-known hard drives are Western Digital and Seagate. The price difference is not big, so you can choose according to your own preferences.
6 Monitor Selection
As the output interface of the computer, the monitor is no longer an issue, so the bigger is the better. For gamers, choose a Samsung model. The monitor is 23.6 inches, which is guaranteed to give you a full experience.
7 In addition to the purchase of the above key hardware components, the requirements for the rest of the power supply chassis are not particularly high. Basically, apart from the beautiful appearance, as long as they can meet normal heat dissipation, of course The sound of the cooling fan is also a factor to consider; finally, with a logical keyboard and mouse, you can even consider a wireless keyboard and mouse, which can instantly upgrade the desktop you assembled to a higher level. Compared with brand-name machines, assembled desktop computers are more like a big family. Although we didn't know each other before, we will get along better after becoming family members.
Hello!
Open the chassis and install the power supply in the chassis.
Insert the CPU into the CPU socket of the motherboard and secure it, then install the CPU heat sink or cooling fan.
Install the motherboard in the motherboard position in the chassis, and plug the power supply cable into the motherboard.
Insert the memory into the memory slot of the motherboard.
Install the graphics card into the graphics card slot on the motherboard.
Install the hard disk, optical drive and floppy drive in the chassis, and plug the data cable into the corresponding interface on the motherboard.
Install PCI interface devices such as sound cards and network cards.
Make the connection between the chassis and the motherboard, that is, the connection of various indicator lights and PC speakers.
Connect the monitor’s signal cable to the graphics card.
Power on and test whether the system can light up normally. If it can light up, a "beep" sound is heard, and the self-test information is displayed on the screen, then turn off the power and continue with the installation below; If it cannot light up, check whether the memory, graphics card or other devices are installed correctly according to the alarm sound.
Install the side panels of the chassis.
Connect peripherals such as mouse and keyboard.
I hope this helps and wish you a happy life!
The power wattage of a desktop computer is the sum of the maximum power consumption wattage of each hardware.
Choose the power supply according to the computer configuration. The power supply also has a conversion rate problem, which is generally around 80%. For example, if the rated power is 500w, the actual power is about 400w, and the actual power only needs to be greater than the power consumption of all the hardware of your computer. That's it.
Power supplies are generally also marked with wattage. For example, a 300W power supply. Rated power: 250W, peak power reaches 350W. At this time, the reference is the rated power.
Choose a power supply:
1. If you don’t know anything, go to a regular online mall to buy it. Such as Tmall, Suning, JD.com, etc.
2. You still have to choose a reliable brand of power supply. And the prices on each website will not differ much as long as they are big brands. Small brands are a mixed bag. Physical stores are not necessarily reassuring.
The harm of inferior power supply to computers:
1. The noise of inferior power supply affects the use of players
A high-quality power supply fan will ensure that the power supply works quietly and stably. However, due to cost issues, low-quality components and low-quality components of inferior power supplies may generate more heat, and their cooling fans are overloaded for a long time. Then it will produce huge noise and affect the normal use of the console by players.
2. Unable to recognize computer accessories, such as hard drives, optical drives and other equipment
Due to the low manufacturing level and low cost of inferior desktop power supplies, basically all the components that can be saved are omitted. . When the output power is insufficient or unstable, it is very likely that the hard drive, optical drive and other devices will suddenly not be found when the computer is turned on.
3. Falsely marked wattage often crashes
The rated power is to ensure that the power supply can output a stable current within this power range, while inferior power supplies usually falsely mark the rated power or increase the maximum The power is marked as rated power, thereby deceiving consumers. If you are playing large-scale games or need the entire machine to operate at high load, then the power of the entire machine will increase accordingly, and your computer will crash.
4. The impure output current will burn the hardware
The performance of general inferior power supplies cannot be guaranteed due to the extremely poor materials and workmanship. It can be seen that there are countless cases of inferior power supplies burning hardware. However, Some players who are lucky or want to save money still choose to take risks. If they burn their hardware, they will lose more than they gain.
1. First connect the VGA cable to the monitor, and then fix the two screws at the back. The main reason for fixing is to worry about the connecting wire falling off when moving.
2. Then connect the other end of the VGA cable to the computer host.
3. Next, connect the power cord to the monitor. (Note that you are only connecting to the monitor. Do not connect the other end of the power cord to the socket. Wait until all connections are completed before turning on the power.)
4. Next, connect the mouse to the host.
5. Connect the keyboard as well. (The green one is the mouse, and the purple one is the keyboard. Also note that the internal pins of the mouse and keyboard plugs must be aligned with the pinholes in the interface before they can be inserted.) Connect one end of the network cable to the RJ45 interface of the computer host, and then connect the other end to the switch or router or modem.
6. Next, connect the power cord of the host.
7. Next, you can connect the power plugs of the host and monitor to the sockets to power on the host and monitor. You can start and use it normally.

There is zero possibility of assembling a tablet by yourself.
Firstly, tablet computers require very high assembly requirements due to their small components (compared to desktop computers). Secondly, tablet computers are relatively cheap and do not have much market demand. No manufacturer sells accessories for assembling tablet computers. The emergence of "compatible machines" on desktop computers was due to the high price of computers at that time. It was easier to assemble after the accessories were standardized, and computer enthusiasts could find the fun of DIY. Therefore, various accessories were sold specifically for assembling computers.Step one: Prepare tools. Tools used to assemble computers include plastic rods, screwdrivers, tin foil, etc.
Step 2: Install the motherboard. First put the motherboard into the computer case, and then secure the screws on the case.
Step 3: Install the processor. Place the processor into the CPU socket on the motherboard and lock the processor.
Step 4: Install memory. Place the memory module into the memory slot on the motherboard, and then secure the memory module in place.
Step 5: Install the graphics card. Insert the graphics card into the PCI slot on the motherboard and secure the graphics card in place.
Step 6: Install the hard drive. Insert the hard drive into the SATA interface on the motherboard, and then secure the hard drive.
Step 7: Install the CD-ROM drive. Insert the optical drive into the IDE interface on the motherboard, and then secure the optical drive.
Step 8: Install the power supply. Plug the power supply into the chassis and secure the power supply in place.
Step 9: Wire the computer. Wire various parts of the computer, including the wiring between the motherboard and the power supply, the wiring between the
graphics card and the power supply, the wiring between the hard disk and the power supply, the wiring between the optical drive and the power supply, etc.
The last step: install the operating system. Install the operating system on the hard disk. Once the installation is complete, the entire process of assembling the computer can be completed.
1.
is to check the packaging. First of all, the box must be new and not too old. The parameter information on the side of the box must be accurate. Make sure it is the model you want. After all, there are many businesses who like to fish in troubled waters and give machines with lower-level configurations and similar appearances to digital novices. Secondly, the box must have a seal. All laptops I have tested, as long as they are new machines, regardless of brand or price, have seals on the outside of the box. I have never seen one without them. Moreover, some first-line brands have high-tech seals. No matter how you tear them off, they will leave marks on the box body, which cannot be restored or removed. They are difficult to forge and are a very important identification point. Although there are some merchants who will replace the entire set of packaging boxes with new ones to fool digital novices.
2.
is to check the fuselage. After unpacking, please carefully check side A first. This is the easiest place to leave traces of use. If there are scratches on side A, there is probably something wrong with the machine. Then shake it and listen to see if there is any abnormal noise or if any parts fall out. Look at the interface to see if there are any signs of plugging or unplugging. Open and close the screen again to see if there is any creaking sound. If so, please return it on the spot. Because even if it is a new machine, it is defective and has quality issues.
Then, if there are no problems, then check the bottom case screws and laptop screws. As we all know, they are extremely soft. As long as they have been screwed, they will definitely leave traces. For gaming laptops, you can also take a look at the air inlets and heat dissipation fins. Machines that have mined mines are running at high intensity. There will be dust in the air inlets and heat dissipation fins. There will also be traces of oxidation. They are black and can be seen at a glance. Can recognize.
