I want to pre order a computer, what should I pay attention to?

1.In the case of the same bai**, the performance of the brand machine is not as good as the performance of the assembly machine, and the brand zhi machine is more in appearance, and the assembly machine is more in the performance dao. (Recommended assembly machine).

2.At present, the host is divided into two series, which are AMD and Intel-type processors, most gamers choose AMD because of AMD's overclocking and other functions are stronger, cheaper, etc., but the power consumption is larger, the stability is low, and fewer advanced players like to use Intel because Intel is stable, low power consumption, powerful performance, etc., **high. (Intel recommended).

3.There are two kinds of graphics cards, one is the NVIDIA type and the other is the ATI type, NVIDIA cards are generally used for games, and the graphics processing of ATI cards is better. (NVIDIA recommended).

4.Motherboards are also divided into two types, one is a pin board designed for Intel chipsets, and the other is a slot board designed for AMD chipsets. (Intel recommended).

5.There are currently 3 types of memory, namely DDR DDR2 DDR3, and the corresponding memory is selected according to the model of the motherboard. (ADATA brand recommended).

6.Hard disks are divided into serial ports and parallel ports, and now most of them are serial ports, because the transmission speed is faster, the cache of the hard disk is divided into 8m, 16m, 32m, 64m, the larger the cache, the faster the extraction. (16M Seagate brand recommended).

7.The voltage of the power supply provides the foundation of the chassis power supply, so the selection of the power supply should exceed the total power consumption as much as possible, so as to avoid the occurrence of abnormal phenomena such as burn-in or automatic shutdown caused by insufficient power supply. (Great Wall brand recommended).

8.There is no doubt that the vast majority of people choose the optical drive, and if you need to burn, you can choose one with the burning function. (Vanguard card recommended).

9.The choice of display depends on whether the main screen has bright spots and other issues, and it is recommended that large brands have higher reputation, better quality, and convenient after-sales. (Samsung, Philips, LG, etc. are recommended).

10.For the chassis, speakers, mice and other parts belong to personal collocation, do not recommend.

I hope the above will be of some help to you, and the specific parts and models can be viewed on Zhongguancun computer network.

Note: The closer the frequency between the CPU, motherboard, and memory, the greater the performance.

When choosing a laptop, you should first clarify your needs, and then choose according to your needs and actual budget.

Learn to use: You can take a look at ASUS Vivobook Pro14 Vivobook Pro15, vivobook15 series, A bean series, ** around 5000 yuan.

Generally choose i5 7 generation or more CPU for playing games,Graphics card choice GTX2060 or above,Memory8G standard configuration16G is the best,There must be solid state,This kind of book is about 6000 or more。

Recommend ASUS Heavenly Choice series, ROG Gamer Republic series (high-end gaming laptops over 10,000 yuan).

Biased to draw,Audio**Editing function,It is recommended to choose i7 10 generations or moreCPU,As long as the graphics card is not too slowing down, it is OK,Memory8G standard configuration16G is the best,This kind of book is about 8000 yuan at a price of about 8000 yuan。

We recommend the ASUS Zenbook Pro series, the Tianxuan series notebook.

Biased towards 3D modeling, this type of graphics card is better, the CPU should be as close to the i7 as possible within the budget, and the graphics card GTX2070 or above is the best, ROG Gamer Republic series or ProArt professional designer notebook is recommended.

It mainly depends on what your computer is used for, office computer, the configuration requirements do not have to be high, if it is used for design, production, drawing, and playing large games, the configuration requirements are higher.

The configuration is high, ** must be expensive, and the office computer is about 3000 yuan. The configuration should be more than 5,000 yuan.

The configuration is different, which is reflected in the processor, graphics card, memory size, storage medium (solid-state, SATA, MSATA), motherboard, hard disk speed, etc. If it's a laptop, the heat dissipation performance can't be ignored either.

First of all, it depends on how much RMB you have, looking at the demand, now there are many scenarios such as thin and light laptops, gaming laptops, ultrabooks, etc., to meet people's needs, looking at the configuration, processor, graphics card, memory, storage media (solid-state, SATA, MSATA, and mechanical) These are combined. Another point to remind is that because computers are different from mobile phones, if the computer is well configured, it can take a little longer.

When buying a computer, you need to pay attention to shopping around, first get a general understanding of the configuration on the Internet, choose the one that suits your needs, don't waste performance, and then go to the physical store to buy.

Cher [Newbie].

1。Choose your own thing according to your own needs.

2。To be sure that what you want must be first-hand goods, and it is a very simple way to teach you a very simple way, new accessories will generally have a smell! There is also a look at the socket of each screw (hardware) to see if there are any friction marks.

The CPU is best original, just look at the box to know if it is original, and the memory to see if there are any friction marks on the gold finger.

3,**Aspect,When determining the configuration, you'd better go online to see the value of these things,But it's impossible not to let others make money.,Because they also have to eat.,Don't think that the cheaper the thing, the more valuable it is.,So you may be brought into the circle.。 If the other party really can't do it (because it doesn't make money), it may be that this brand of motherboard is no longer available (use this tone to achieve the purpose of making money by changing your brand or model), and you must stick to your position at this time.

4. It's very risky to find a friend to take you, because I've seen this situation too many times in the four years I've been in Zhongguancun, so I'll make a point! Please don't mind!

1. Look at the serial number. Most laptops should have the same serial number on the body and battery, if the battery serial number is inconsistent with the serial number of the host, the battery is very likely to have been replaced; In addition, when purchasing foreign brand notebook products, whether the serial number of the fuselage is consistent with the battery and the outer packaging is a very important basis for checking whether the product is parallel import, and it is important to know that foreign parallel notebooks cannot enjoy warranty in China.

2. Look at the anti-theft lock hole. If there is an imprint, it means that the notebook anti-theft lock has been inserted, and it is very likely that a prototype has been made;

3. Look at the feet. If it is worn and dirty, it means that it has been used and the workbench on the production line is not so dirty;

4. Look at the cooling fan. If the fan blade already has a thin layer of dust, it means that it has been used for more than a week;

5. Look at the production date. The original book that left the factory three months ago is still on the market, so you should pay attention. The sales of electronic products are updated very quickly, and it is impossible to let a book be pressed in the channel for so long.

6. Look at the keyboard. The keyboard of the new book is clean, but it doesn't shine. There will be dust in the cracks of the used keyboard, and the few keys that are commonly used will be polished;

7. Look at the screws. Whether there are traces of demolition.

8. Look at the gaps. The refurbished book,The gap is generally difficult to deal with as new,For example, the small gap between the AB surface of the screen,For example, the gap between the optical drive,Even in the interface of modem and PCMCIA card,If you can find dust,It is certain that it has been placed in the prototype,And it is not sealed。

9. LCD screen, the biggest headache when buying a notebook is the bad point, after all, no one wants to have a few highlights in the new notebook they buy, right? But almost no manufacturer promises that there are no bad points. Among the notebook manufacturers, only ASUS promises no bright spots, this is just a play on words, there are too many dark spots, and I can't stand it!

And they call colored dots color spots, and they can't guarantee them if they are not bright spots, so now according to this standard, it's really hard to say what bright spots are.

Laptops should now be a must-have for college students, and after going to college, many of our homework is written on the computer, and directly submitted by the computer, so the laptop has to be bought. But when buying a laptop, many students are very confused, because they are not studying this major, so they don't know much about this aspect, and they don't know what aspects they should look at when buying and what performance they should understand.

cpu。The operation of the computer system depends on the CPU, it can also be said that all operations on the computer are controlled by the CPU, the performance of the CPU directly determines the performance of the computer, so you should know how important it is, the current CPU is generally i3, i5, but i5 is used more, and the most popular this year should be said to be i5 eight generations, he is the latest CPU running system, it can also be said to be the best now.

Display the screen. One of the most important and fundamental things to do when buying a computer is to look at the size of the display screen. Nowadays, the most popular and common size should be and two sizes, which is used by most people.

If you are often sitting in the office or your computer is not always going somewhere else, I recommend that you buy a larger one, that is, yes, because the screen is large, and the most direct thing is convenience, so that we can look at the screen more comfortably. But on the contrary, if you need to carry a computer everywhere for study or work, you need to buy a smaller one, you can consider buying a 14-inch or 12-13-inch one. Because it is too big, it will be very heavy, and it is particularly inconvenient to carry around.

Memory. I believe that when you buy a laptop, the most common thing you look at is memory, which is the most well-known parameter as an important parameter in the computer. Memory is the CPU temporarily stores data when it is running, or how many software can the computer run at the same time in the background, and now the general ones on the market are 4G or 8G, and the 2G ones are very few, in fact, 4G or 8G are all OK in the case of our general use, and they are enough.

Hard disk. Nowadays, most laptops are dual-hard drives, with SSDs and HDDs co-located. But that's just the majority, some actually only have SSDs, and some only have HDDs, but the advantage of SSDs over HDDs is that they make computers run faster, and that's because our systems are all in SSDs.

Therefore, I think that when buying a computer, if he only has a mechanical hard drive and no solid state drive, it is best not to buy it, because it can be said that such a cost performance is really not high.

If you buy an assembled computer, you should pay attention to the compatibility of each fracture, and a small port may also bring big problems to your computer in the future. The company you buy a computer must have a good after-sales service and a certain scale. Look at the repair period on your repair order, otherwise it will be very troublesome, which computer has not had a problem?

In price. You have to check it before you buy it, there are those things on the Internet. If it is a brand machine, it is necessary to see whether it is encapsulated, and if it has been dispersed, it is shoddy.

Consider your own needs first, and then roughly determine a performance configuration and scope. The main thing is performance and configuration, and then, to see if the exterior design and workmanship are exquisite. Some have giveaways, in fact, don't think too much, if there is good software or a better computer bag or something like that, the quality of the gift hardware (such as a mouse) is very poor, and even I bought a new one.

The rest, such as the paint surface of this book is easy to stain, such as fingerprint prints, etc., such as the practicability of frosting is better. In addition, the hardware is too cost-effective, and the hardware quality may not be very good, or most of them do not provide genuine systems (some of the original configuration is DOS.)

and so on).

Pay attention to the money in your pocket.

Be mindful of what you're going to do with it.

Be careful not to be fooled by the salesperson.

Be careful not to force yourself to buy one.

Be careful not to charge a big head, obviously the computer bought for 2000 is suitable for you, but you have to spend 4000 to buy a so-called better look.

Be careful, don't think that Sony's books are better than Lenovo's.

It's good to buy a game that can be played.,It's a little difficult.,You first simulate it on the Pacific Internet.,Almost with that** to bargain.,Now 19's is less than 1000 yuan.,BenQ has a good cost performance as long as it's less than 800.。

Buy a computer with a good configuration In fact, we can look at 3 major parts, we can see that many computers now have a sidebar on the right side of the desktop, there may be LCD dead pixels below, we can ask to turn off the view, and the sound level of the main chassis, with the naked eye to see if it is a real LCD panel.
