PHP editor Xigua is here to bring you a complete computer inspection guide, detailing all aspects that need to be inspected, including appearance, performance, accessories, etc. By reading this article, you will master the skills of inspecting complete computers to avoid purchasing defective products.

How to inspect the complete computer?

1. How to inspect the complete computer?

1. Inspection method 2. When inspecting the complete computer, you can follow the following steps: a. Appearance inspection: Check the appearance of the complete computer for obvious scratches, deformation and other problems, and check whether the interface is intact. b. Functional test: Power on test to check whether each hardware device is working properly, including monitor, keyboard, mouse, sound, etc. c. System check: Check whether the operating system is installed normally and whether there are any abnormal prompts or errors. d. Performance test: You can run some common software or games to test the performance of the entire machine. e. Network connection test: Check whether the network connection is normal. You can try to browse the web or make online video calls, etc. 3. During the inspection process, you can also pay attention to some other details, such as checking whether the power cord is intact, checking whether the hard disk has abnormal sounds, etc. In addition, some professional inspection tools or software can be used to assist in testing the performance and stability of the complete machine. The purpose of inspection is to ensure that the purchased computer meets the expected quality standards and to avoid purchasing products with quality problems.

2. Does the complete computer include a screen?

The complete computer includes the screen. A complete computer usually refers to a complete computer system, including hardware components such as a central processing unit, memory, hard drive, motherboard, graphics card, sound card, and network card, as well as external devices such as a screen, keyboard, and mouse. Therefore, the screen is an important part of the computer and is an output device used to display images and text processed by the computer. Different models of computers may be equipped with screens of different specifications, but they basically include the screen part.

3. How to install the complete computer after buying it?

1. Step 1: Tools and components. First of all, you need to prepare the corresponding tools, such as screwdrivers and screwdrivers. Usually, simple tools are given when you purchase the case. At the same time, you must also prepare various components of the host such as motherboard, graphics card, memory stick, CPU, power supply, chassis, etc.

 2. Step 2: Install the CPU. The installation of the host starts with the CPU. Unpack the motherboard and CPU packaging boxes, take out the motherboard, find the location of its CPU interface, and press the lever downward to open it. Then take out the CPU and align it for installation. Be gentle. Be slow and careful to avoid bending the CPU pins.

 3. Step 3: Install the cooling fan. If it is a boxed CPU, it will come with a cooling fan, which can be installed on the motherboard together with the CPU. If you purchase a separate cooling fan yourself, you need to apply silicone grease to the CPU before installing the fan.

 4. Step 4: Install the power supply. Place the motherboard with the CPU installed next to it, first disassemble the case and then install the power supply. Here you need to use a screwdriver to tighten the screws to fix the power supply in the case, and remove some cards on the back of the case to facilitate the installation of the motherboard later.

 5. Step 5: Install the motherboard. After the power supply is installed, you can fix the motherboard inside the chassis, determine the installation direction, and then use screws to fix the motherboard. Be careful not to make a mistake. You can confirm it by looking at the slot of the graphics card. It is generally easier to find the direction.

 6. Step 6: Install the memory module. Take out the memory stick. If it is two memory sticks, it is recommended to install it in slots 1-3. If it is a single memory stick, install it in the second slot. After the memory stick is installed, press the fixing rings on both sides to ensure The memory stick will not loosen.

 7. Step 7: Install the graphics card. Then take out the graphics card, align it with the slot and install it. At the same time, use a screwdriver to fix the graphics card on the chassis to ensure that the graphics card does not shake left and right, and the interface of the graphics card needs to face the outside of the chassis.

 8. Step 8: Wiring. After these are installed, you can observe the layout of the chassis, and then start wiring. In principle, it is better to be as simple as possible. You need to connect the graphics card, motherboard and power supply. At the same time, the motherboard may also need to be connected to the graphics card.

 8. Step 9: Others. If there is an optical drive on the host, you need to install it on the upper part of the chassis and fix it with a screwdriver. Then connect the power supply and the motherboard. After all the cables are connected, you can connect the monitor to test whether it can boot normally.

4. Which brand of complete computer is better?

If you want to play games and draw, it is better to choose Lenovo Y series. Since your budget is 4000~5000, I recommend you to buy Lenovo Earthlings, Aliens, etc. which can easily cost tens of thousands or even hundreds of thousands. Ordinary people buy generic ones like Acer. Dell. Lenovo. ASUS's mass-priced ones are OK. Of course, there are also tens of thousands series like the ones above, such as Acer's Hummingbird. Lenovo's Y500 and above, Dell's Alienware, etc. all cost tens of thousands. So as long as you buy a notebook with a third or fourth generation i5, 4G memory, and NVIDIA GT630M or above graphics card, it can handle general mainstream games or graphics. Of course, if you want to get a Core i7, you can only get the domestic Alien Shenzhou Ares series for 4,000 to 5,000 yuan. The configuration is very good, but because the brand is not popular, although the configuration is good, the Chinese are not very interested. For cost-effectiveness, you can consider Shenzhou Ares.

5. How to calculate the power consumption of a computer?

You can search and review the peak power consumption of 9900K online. The main thing is to look at the power at high frequencies during gaming.

Generally, dual 8-pin graphics cards are capped at 150+150+75 (PCIe power supply) = 375W. The magic dragon has 3 8 pins and is generally priced at 420-450. Flashing the BIOS can be higher.

The total of other zeros and zeros add up to 50W, which is enough.

The peak value of 9900K should be close to 350+W

So basically you have to buy an 850W power supply.

6. Which Taobao computer manufacturer is reliable?

No one is very reliable when buying a computer host on Taobao!

Why is it said that Taobao as a whole is unreliable? First of all, let’s just say that Taobao has several types of stores. I will explain them slowly according to the types.

The first type: foreign junk computer

The so-called "foreign junk computer", this is the best to identify and the most unavailable to buy. It has two special effects: 1. Inter Xeon processor, i7 level or This is the description of i9 level. 2. The motherboard, memory, hard disk, and graphics card are not labeled with brands. They are all labeled as a certain gold disk motherboard, or a military solid-state motherboard, etc.

Why do you say that this kind of computer cannot be bought, and why do you call it a "foreign garbage" computer? First of all, the Xeon series processors are server-level CPUs and have been discontinued a long time ago. Currently, what is circulating on the market is second-hand foreign garbage that has been eliminated by foreign countries. Some Chinese businessmen ship these garbage processors Come back and sell it to novice players who don't understand.

A friend of mine just wanted to buy a computer. When I saw the description of i7 and i9, I thought it was very awesome. I just bought it without thinking about it. But as long as you search for this type of processor before buying, you will find that This type of processor is very cheap, costing only RMB 20 or RMB 30. However, the i5-9400f, our current mainstream and cost-effective CPU, costs RMB 950 or more.

The second type: second-hand computers

Compared to the first type, this type of computer is more conscientious. After all, second-hand trading is normal. The hardware used in this type of host is relatively good. Generally, merchants will inform you of the specific brand and model. , so you can spend very little money and buy a very cost-effective computer, which is very suitable for friends who pursue the ultimate cost-effectiveness.

The pitfall of this kind of host computer is whether the specific brand is notified. Second-hand hardware of big brands is guaranteed and safer, but I am afraid that some stores use second-hand goods from small manufacturers, which is dangerous.

The third type: online merchant brand machines

Online merchant brand machines generally sell regular machines with mainstream configurations. They are not like traditional brand machines, which are very expensive. They are sold very cheap, even Cheaper than what you get yourself. For example, brands such as "Ximei", "Xiansheng", "Xiaoji" and "Xixue brothers" on Taobao all fall into this category. Although this type of machine is a regular machine and the price is very affordable, it is still very misleading.

This "cheat" is reflected in shrinkage. Basically, all accessories are special editions provided by online merchants. They are castrated in terms of configuration, such as being "limited to death", "cannot change configuration", and "no". "Supports the original factory warranty", and other problems such as "poor quality", "easy to break", etc. are all its shortcomings.

Fourth type: DIY assembly

Some friends don’t know how to install the machine, but don’t want to buy an expensive brand machine, so they will find this type of shop to design and assemble it for themselves. The advantage of this type of machine is that it is cheaper than the brand machine, and it is larger Some store owners are also very conscientious and use branded accessories, but they generally do not bear the shipping costs and ask players for high installation fees. And it is likely to cause damage during transportation! The gain outweighs the loss!

So the water on Taobao is still very deep. The best thing is to assemble it yourself. If not, try to go to offline regular shopping malls or specialty stores to buy branded machines!

7. Can I buy complete computers on JD.com?

Yes, JD.com is a comprehensive e-commerce platform that provides online purchase services for various commodities, including complete computers. On JD.com, you can find a variety of complete computers of different brands, models and configurations, and choose the product that suits your needs and budget.

When buying a complete computer, it is recommended that you pay attention to the following points:

1. Understand your own needs: Before buying a computer, be clear about the purpose and needs of the computer you are buying, such as whether you need a high-performance processor, large capacity memory, independent graphics card, etc.

2. 比较不同品牌和型号:在京东上,您可以浏览不同品牌和型号的电脑整机,通过阅读产品描述和用户评价来了解产品的性能、质量和性价比。

3. 注意售后服务:选择购买电脑整机时,建议您查看售后服务政策,包括售后保修期限、维修点覆盖范围等,以保证您在购买后的售后服务和维修方面能够得到及时的支持。

在京东购买电脑整机也可以享受一些购物的便利,如多种支付方式、快速配送等。但请注意,购买前仔细阅读产品信息、用户评价和商家政策,做好选择以确保购物的满意度。

八、电脑整机发货注意事项?

1.电脑主机在发货时,要检查所有配件螺丝是否有松动,特别像硬盘一定固定好。

2.电脑一定要打开机箱,在机箱里面用空气泡沫填充,固定后再盖上侧板。减少里面配件的左右晃动。

3.如果电脑里面有独立显卡,而且比较大或是长的显卡,建议取下来,单独包装发货。减少显卡和主板显卡插槽的摔坏。

4.机箱外壳一定要用空气泡沫包裹,再放入机箱盒内打包,这样减少外壳受损,减少震动对硬件的伤害。

九、电脑整机发货还是散件发货?

这个要看你怎么买了。

如果是买整套组装好的主机,当然是整机发货的。现在的包装都很严实,不怕快递暴力破坏,就算快递运输过程中有损坏到主机,商家也会妥善处理好的。如果发散件过来还要你安装,那样反而会增加商家的成本,因为不懂装的,会老是问客服,本来两三分钟就能装好的,客户可能半个小时也装不好,时间成本就增加了。

如果你买的是散件,说明你自己就是个行家,买回来自己组装的,商家也会按照你的要求寄散件的了。

十、买电脑整机有电源吗?

买电脑
