Someone who has experience in installing a computer comes...

Of course, open the unopened hardware you need in front of the customer to show the customer! The hardware is a cardboard box, with a plastic bag to prevent light from entering, and contains hardware such as motherboards, graphics cards, and hard drives. The memory is generally packaged in a hard plastic shell, and the CPU is a large cardboard box, which contains a plastic box (not counting the loose ones).

Today's businessmen are okay, and there are not many people who use fakes in front of customers! But I recommend keeping an eye out for it!

Now there are generally three certificates in the first line: product certificate, warranty certificate, and product manual.

Moreover, the packaging is generally sealed packaging, and it is recommended not to buy in bulk.

Just like the CPU, the boxed is more expensive than the bulk but it is definitely not a parallel import, of course, the parallel import of the CPU is less, but the second-hand cannot be ignored.

As for the motherboard, memory, hard disk, remember to buy a sealed one, and look at its three certificates, the hard disk and the memory motherboard should have a ** and identification bar that can be queried, pay attention to the distinction.

You can open a configuration order and let the boss match it to you on the spot, of course, you can see whether it is licensed or parallel goods, you must pay attention to it again, it is recommended to go to the brand store or a famous brand installation store with a long history to install, so that it is guaranteed.

Licensed hardware comes in sealed plastic packaging.

No, you don't. Anyway, there are quality packs.

You can check your hardware box online.

There are also some brand-name things that can be authenticated online.

Like Kingston West Count or something.

And the configuration sheet he gave you, you must keep it.

What if he drops the bag later?

Nabs. You tell me?

Generally others have packaging.

Like something special, there isn't.

For example, memory, CPU, but the CPU buys a boxed package, and a fan is also given.

Memory is generally sent by one card, which is one card and ten cards, which is the kind that is collectively packaged.

Well, you can see for yourself that the rest have packaging, and these two are a little special

No, it's supposed to be the hardware of the machine, the system and then show you.

Hardware box If you want it, he'll give it to you. There is also a warranty card.

If the CPU is in bulk, some have a box and some do not have a box, it depends on what the CPU is, pay more attention to the gold finger when looking at the memory and graphics card, and you can see if you have used it to see the scratches, and the hard disk should pay more attention to it, some hard disks are refurbished by them, look at the scratches on the surface of the hard disk, and whether the interface is cracked, etc., you always know, the accessories of the assembled computer can be seen as long as you are careful

You'd better find someone who understands to accompany you to the motherboard, monitor, CPU, large parts, and generally very few fake ones, and small pieces are where the profits of the JS lies

Anyway, there is a warranty, what are you afraid of, the general warranty is 3 years.

If you have a guarantee, you will buy it, it is not simple.

To assemble a computer, in addition to buying the accessories needed for the computer, you also need to prepare a Phillips screwdriver.

The configuration of the computer is as follows.

Host part: 1, CPU. The heart of the computer, which is responsible for calculations;

2. The display core of the graphics card and computer is used to process image data. If you're a gamer or grapher, you'll 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;

4. Hard disk. All files of the computer are stored here;

5. Motherboard. The various parts of the computer are installed on the motherboard and work together;

6. Power supply. power supply to each component;

7, chassis. Used to protect all parts inside the chassis.

Peripherals: 1, display. images used to display computers;

2. Keyboard and mouse. for operating a computer;

4. Audio. Used to output sound;

6. Microphone. Used to input sounds, voice chats, and more.

Assemble the computer. Assemble according to your daily needsNot the higher the better.

First, disable some unnecessary boot items: shut down and restart, press "F8 key", select "Safe Mode" to enter the system, click "Start" Run" (or use the key combination "Windows key + R key") to bring up the run bar;

Enter "msconfig" in the run bar (or OK) to bring up "System Configuration";

In the pop-up system configuration dialog box, find the "Services" tab and click it, first check the "Hide all Microsoft services" item under the service label, then check all the non-Microsoft services listed in the above box, find out the services that need to be started at boot, and click "Apply" in front of the service item.

Click on the "Startup" tab, find out the unnecessary boot startup program, go to the previous "tick" and click "Apply" OK to "exit the "System Configuration", and restart the computer.

Start the computer normally and enter the system, and repeat the above steps again;

With the help of third-party tools, such as System Optimizer in PC Manager, the system boot is optimized again.

The person who assembles the computer should have some basic knowledge and practical experience in electronics; Second, it's a good idea to observe and learn how someone else has built a computer correctly (it's best to demonstrate it here); If you want to successfully assemble a microcomputer that meets the requirements, you should also understand the performance and technical characteristics of various relevant accessories in the micro-dust god computer, their use methods and technical requirements, and master the correct software and hardware settings and configurations.

understand the general testing methods of computers and accessories; Finally, the person building the computer should also be familiar with the basic ways to use the computer.

Precautions for computer installation:

1. Before installation, the static electricity on the body should be discharged to prevent the lead from penetrating the various semiconductor components in the circuit components due to electrostatic discharge, and the specific method is to touch the objects that can be connected to the earth, such as water pipes, heating pipes, etc., or simply touch the metal part of the chassis.

2. Before installation, you should carefully read the manuals of various components, especially the motherboard manuals, and set the jumpers correctly according to the type of CPU.

3. When moving computer parts during the installation process, you should handle them with care, and do not drop the computer parts on the floor, especially for CPU, hard disk and other brittle and expensive parts, it is forbidden to move the computer during the boot test to prevent damage to the valuable parts of the hard disk.

General steps to assemble a computer:

Whether you are assembling a new computer or rebuilding it after repair, the following steps should be followed when assembling it:

1. Preparation;

2. Install CPU and fan on the motherboard;

3. Install a memory module on the motherboard;

4. Fix the motherboard on the chassis bottom plate;

5. Connect the power cable of the motherboard and the power cable of the CPU fan;

6. Connect the switches, indicators, and power switches between the motherboard and the chassis panel;

7. Install the graphics card;

8. connecting the display;

9. connecting the keyboard;

10. Basic system for power-on test;

11. Install the floppy disk drive;

12. Install the hard drive;

13. installing an optical drive;

14. connecting the power plugs of each component;

15. Installing the connecting string and parallel interface;

16. Install the ISA card (if any);

17. a final inspection;

18. Start up the BIOS setting program and set the system CMOS parameters.
