PHP Editor Banana brings you a practical guide detailing how to test whether your computer is an assembly machine through a series of simple steps. This article will analyze each key indicator one by one and guide you to clearly identify the assembly attributes of your computer. Continue reading this article to easily master this technology and avoid the potential pitfalls of purchasing an assembly machine.
Therefore, if you use software to detect it, you will be prompted which brand of machine it is. Judging from the appearance, the chassis and monitor generally have the LOGO of the brand;
The accessories of the assembly machine are randomly matched, and the motherboard brands and models vary. , the configurations vary. If you know the model of the brand machine, you can basically know all the configurations of the machine by searching online; there is no model of the assembled machine, you can only check the configuration through your own software;
If it is a notebook, the notebook is also assembled Yes, there is no serial number for the assembled machine. You cannot find the serial number of the fuselage on the official website. You can find the serial number of the brand machine on the official website. The brand machine has a fixed model and configuration. How to assemble the computer with the assembly machine and desktop
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.
Causes and solutions:
1. The memory module is loose or damaged
Solution: Wipe the gold finger of the memory module with an eraser, and reinsert the memory module; replace the memory strip.
2. Poor contact with the graphics card
Solution: Same as the memory method.
3. The host is short-circuited.
Solution: Clean the host and reconnect the wiring.
4. Motherboard BIOS problem
The motherboard BIOS stores important hardware data. Once it fails, the computer may not start.
Solution: Enter the motherboard BIOS setting interface and restore the bios to the default value.
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. And 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 are any abnormal noises or if any parts fall out. Look at the interface to see if there are any traces 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.
When choosing to assemble a computer, pay attention to the following parts:
1. Look at the price. Choose a computer that suits your price based on your budget. Be careful not to buy a computer with too low a configuration at an exorbitant price;
2, look at the performance. Buy it at a reasonable price based on the computer performance you need. Be careful not to buy a computer with low specs at an exorbitant price. The complete configuration of the computer is as follows. Host part: 1. CPU. The heart of the computer is responsible for calculations. The more cores, the better the performance; 2. The display core of the graphics card and computer is used to process image data. If you are a gamer or graphics worker, you need a discrete graphics card. If you use it to surf the Internet, you don’t need to buy a discrete graphics card;
3, memory. Used for CPU and hard disk to exchange data for temporary storage. The more memory you have, the better the performance will be;
4, hard disk. All your computer's files are stored here. The harder the hard disk is, the more files it can store;

1: The first step: Determine your own needs:
1. Determining your own needs is the first step in doing anything. Before buying a machine, think clearly about buying a new machine. Finally, what is the main purpose? Different groups of people use computers for very different purposes. A clerk in a company and a person who mainly plays games have very different needs for computer configuration. We should, while meeting our own needs, It is only right to choose according to the most suitable budget.
2. For example, as an optional computer for general office use (except for professional software office needs), the Pentium G4560 without independent graphics is enough for daily office work, but if you have graphic design software such as PS and need it, a larger computer will be needed. Memory and gaming requirements require a better graphics card, so before you start choosing a computer, it is most important to determine your own needs.
2: Step 2: Determine the CPU
1. The first choice for all computer accessories must be the CPU. The order of selection should be to select the CPU first, then determine the motherboard, and then Determine the memory module (memory modules are so expensive now!), then select the graphics card, cooling, hard disk, etc., calculate the power consumption, and finally select the power supply and chassis.
2. If you are not a garbage person, it is recommended to buy new rather than old CPUs first. Although CPUs will not wear out, there are no new motherboards equipped with old CPUs. Old motherboards are very It's easy to have all kinds of problems, and if you're a novice and can't get a good motherboard, it's easy to fall over. Of course, it doesn't matter if you're a trash guy.
3. You can actually choose either AMD or Intel platform. After all, AMD has successfully turned around with Ryzen, and it is not inferior to Intel in all aspects. If you have to give a recommendation, then it is enough ( Those who watch movies, play LOL games, browse the web, and work lightly) can choose Intel's Pentium processor. For gamers, choose Intel Core processors with higher single-core frequencies (in fact, i3 is enough, because Games require more graphics cards), and professional practitioners who need a lot of video rendering and design choose AMD's Ryzen platform.
Three: Step 3: Determine the motherboard
1. After determining the CPU, the pins are determined, and then there is a rough range of motherboards with the same number of pins, and then take a look at yourself Do you have any special needs, such as whether you need overclocking, how expandable the memory module is, whether you need an m.2 interface, whether all the required interfaces are complete, etc. As long as they are met, the rest is worth every penny. The products are distributed, just choose a motherboard you like.
2. Many people have two extreme attitudes towards motherboards. One type of people prefers to use the lowest-end graphics card, while the other type of people have a very large budget for motherboards. The author Then you feel that you should choose a motherboard that can meet your needs, i.e.

First install the casters one by one on the chair legs. After installing the chair legs, place the air pressure rod vertically into the center of the chair legs
2
Then fix the chassis to the seat with screws
3
Then connect the chair back and seat, and insert the base vertically on the air pressure rod
4
Finally install the armrests and headrests and you’re done
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 computers" 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 fix 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 secure the memory module in place.
Step 5: Install the graphics card. Insert the graphics card into the PCI slot on the motherboard, and then secure the graphics card.
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 onto the hard drive. Once the installation is complete, the entire process of assembling the computer can be completed.
