What should I pay attention to when buying a new desktop computer? The more detailed, the better. Th

1. Desktop computers are divided into brand machines and compatible machines, and there is usually a 1 3-year warranty period for buying brand machines, while compatible machines need to agree on the warranty content with the seller;

2. Determine your own psychological price, and then check online**;

3. To check the brand desktop or compatible machine in the target price segment on the Internet, you must first compare and look at the specifications and brands of key components such as CPU model and main frequency, memory, hard disk, graphics card, display size and resolution (compatible machines need to add the ** of each accessory by themselves);

4. Secondly, look at the appearance of the chassis and display, and choose the appearance you like;

5. Finally, look at some details clearly, such as the operating system, optical drive, port, keyboard and mouse, etc.;

6. If you go to a physical store to buy, you should write down the models of several brand machines, the configuration of the main components and the best products you have picked on the Internet, so that you know what to expect.

In terms of performance, there is also hardware not to be fooled. Regarding the configuration, the power supply must be sufficient, otherwise it will cause the computer to be unstable.

Look at the CPU, motherboard, graphics card model, memory, hard disk, monitor size.

According to your requirements, CPU model, CPU only 2 brands, Intel and AMD

Intel:e5300,E6700,Or i3 series is enough,Up to i5,Generally, i5** computers are about 5000,So it's still the first 3,According to my order, one is more expensive than the other,Of course, the performance will be higher。 The first 2 models can be a little larger.

AMD: Athlon II X2 245, Athlon II X2 255, Athlon X4 640, AMD Phenom II X4 955, AMD Phenom II X4 965, suitable for your old ones, the performance is also sorted according to the order.

The motherboard generally comes with the CPU, the low model is about 600 yuan, and the high model is about 800 yuan.

Personally, I recommend you to use Athlon X4 640, a 4-core CPU, about 650 yuan. You can match an ASUS motherboard of about 700 yuan, such as 880g.

There are many graphics card models, you can go to the Pacific Computer Network, the graphics card section, and you can see the graphics card ladder diagram by clicking on an article at will, which is simple and clear. Buy the levels you need. Personally, I recommend you to buy a mid-range graphics card and play online games without pressure, such as GTS450 or HD6750.

Memory, hard disk, monitor size, memory is generally 2g, hard disk is at least 500g, of course, the bigger these 2, the better. Display 21 23 inches, almost, I personally recommend 21 inches, 23 inches is too big and inconvenient.

That's pretty much it, I recommend your configuration to be around 3500.

First of all, consider the power supply, because if the power is not enough, the computer will not run smoothly.

In fact, when the hardware is unpacked and installed, multiple eyes check whether it is the first time to unpack and see if it is genuine.

After installing the system again, check whether there is any discrepancy between the configuration of the hardware and the configuration written by the salesman.

Finally, let the system installation staff help you back up the system and burn a system disk, the main purpose of this is to prepare for the system to be unable to find the system disk in the future.

1.In the same case, the performance of the brand machine is not as good as the performance of the assembly machine, and the brand machine is more about the appearance, and the assembly machine is more about the performance. (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.

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.

4.The motherboard is also divided into two types, one is for the Intel chipset.

The other one designed with a pin board is a slot board designed for AMD chipsets.

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.

6.Hard disks are divided into serial ports and parallel ports.

Nowadays, most of them are serial ports, because the transmission speed is faster, the cache of the hard disk is divided into 8M, 16M, 32M, and 64M, and the larger the cache, the faster the extraction speed.

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.

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.

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.

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.

First of all, don't buy outdated stuff! For example, AMD's latest CPU is either a bulldozer with AM3+ interface or an APU, of course, Phenom II and Athlon-II can also be considered, and those older than this should not be considered! Intel's just depends on the pins, 1155's can be, everything else is outdated!

Don't buy the 1156 either, it's the first generation Core i series, it's not recommended to buy!

If you have a motherboard, try to choose ASUS, MSI, and Gigabyte, the three first-tier manufacturers, if you don't have money, ASRock, Onda, these second-tier ones are OK, and don't buy the lower-end ones!

If the memory is a brand of goods, ** on the line! Such as Apacer, Kingston, ADATA, G.SKILL, Corsair, and Samsung are all branded!

Power supply, such as Zhenhua, Kangshu, Great Wall, Huntkey, Antek, Corsair, Yinxin, Cooler Master are good, if you don't have a separate display, the big buffalo, Jin Hetian can be considered!

Monitors, Samsung, LG, AOCDell, Philips, and Acer are all OK!

In the final analysis, you don't understand hardware, even if the accessories are all first-class licensed goods, all are first-line, they can only be guaranteed in quality, as for performance, cost performance is not guaranteed, people must pick the most profitable for you!

Personally, it is better to buy a desktop machine, and now the popularity of the installation is very wide, and all the hardware is transparent, and you can query the specific parameters, performance and ** on the Internet. You can refer to the online ** and performance selection hardware to buy online in the physical store to help assemble, up to 100 installation costs. If you are not sure about the authenticity of the Internet, you can choose to inquire about the ** and model online, and let them purchase it in the physical store, one guarantees the authenticity, and the other guarantees the after-sales.

Personally, it is recommended not to buy a brand machine, for two reasons, first, the early stage of after-sales is very convenient and free, but the later after-sales delay is long, and the procedures are troublesome, and the later ** is very high. Second, the relative performance configuration of the relative installed machine will be more than 1000 higher, after all, people have brand profits. Saying all that, I don't know if it can help you. Hehe.

The first thing to pay attention to is the key components that affect the speed of the computer...

Hard disk, CPU, motherboard, memory.

They are joined together like water pipes, and where one is thin, the whole stream of water is thin.

So be sure to get the most out of it.

If the CPU supports GPU or APU, then you can save the graphics card, you need a motherboard that can play CPU performance or close, do not integrate the graphics card with the output of the graphics card, according to the main frequency of the motherboard to support the memory to choose the appropriate memory, hard disk, try not to high-speed ,,, because the general is enough, the higher the speed, the better the reading ability, but the heating, the hard disk life will also accelerate aging.

The above is about performance and hardware.

The model of the hardware It is best to test the hardware model after installing the machine. The easiest test is with Master Lu.

First of all, you need to determine what you are buying the computer for, and how much money will you prepare to buy it? How often do you plan to renew it?

Generally for individual ordinary users, (rookie level) it is best to buy a brand desktop, so that compatibility, assembly, etc. do not need to worry, if there is a manufacturer in use who does not understand the after-sales engineer will answer for you in detail (large manufacturers have tracking visits, if the engineer service is not good to be complained, bonus ,,, you know), want to drive and other manufacturers will have special software to upgrade.

If you are compatible with the machine, it is best to find someone who understands it to help you design a good configuration, calculate the power, choose the power supply and other sustainable upgrade accessories, inquire more, and find a parts manufacturer with a good reputation to buy (leave the profit to others, otherwise you will be miserable with other parts or repair parts), and now some e-commerce ** also have installed machines, if all the pieces are purchased on its platform, if they can be delivered to the home for assembly within the range.

If you have nothing to spare, it is recommended that you go to the "Computer Newspaper" to take a look or go to its official website to wander around, many articles are very good and enlightening to you.

It's best to find someone who understands to accompany you, and don't go to an acquaintance to match, it's easiest to be pitted by acquaintances.

If you don't know the computer, just buy the brand machine directly according to the price you estimate in your heart, the performance is not the highest, but it is stable enough, and the after-sales service is better.

First, determine what to buy a computer for, such as games, movies, surfing the Internet, office, second, determine how much to buy, do not pursue high configuration, the current computer three use expired, insist on enough, upgrade can keep up, third, properly go online to master some computer hardware knowledge and matching requirements, do not let the business worry. Fourth, find a knowledgeable cloud matching machine. Fifth, in principle, the assembly computer for personal use, the brand computer for the unit, and the assembly computer can flexibly allocate hardware, and can save a lot of money, which can be used to buy better tables, speakers, etc.

You can also buy a better graphics card, and you can play games when you are familiar with it in the future. Brand graphics cards are super bad, so they are not recommended for young people, especially those who play games.

First of all, you have to clarify the purpose of the machine you buy, and then configure it according to your needs, and you need to pay attention not to let others fool you with second-hand goods, especially memory modules

Graphics card 1G independent display is enough Bit width 64 or more Recommended GT630 or more 3: Memory 4G or more, dual channel, if there is 2G, buy one yourself, it's not expensive now, the price of cabbage.

4: If you are not a gamer, just buy a normal one at a price.

5: I wish you a happy purchase.

Shop around. Look at a few more. Ask a knowledgeable configuration in advance. Take this configuration. Run a few more. **Compare.

Go to a regular place. Before buying, search for more specific information on the Internet, don't let people see that you are a novice, the minimum knowledge should still be understood, and find your ideal configuration according to the specific budget. Record it and go to a place like Zhongguancun to buy it.

Don't be influenced by those solicitors and trust your own judgment. It's best to go with friends.,People don't dare to pull you casually.。。

Dizzy. Why not buy a computer locally Buy it locally There is also a warranty. Free repair during the warranty period

And it's easy to maintain. At least a year to maintain ash cleaning without money. What to do after buying and selling online.

If you don't play a big game, it's about 2,000 5 to get a good oneMainly motherboard CPUsIf you turn it on for a long time, the power supply will be good.

Discrete graphics card is suitable for netizens who play big games If you want the computer not to be poisoned, then install a w7 Although it is slow, it is better than XP Beware of viruses when you use them.

The key is how much you're prepared to spend.

Now the 2400 can be equipped with a computer.

Intel Platform:

Core i3 i3-530 Box 740 Western Digital 500G AAKX 265 Memory Kingston DDR3 1333 2GB 150 MSI H55M-E21 520 GT220 395 Huntkey Cool Diamond King Win7 Edition 190

Ordinary chassis Ordinary *** optical drive Ordinary keyboard and mouse 260 Display: AOC 19-inch LED screen - 730;22 inch LED screen – 890

Between 3250-3400.

First of all, you have to go to the Internet to see all kinds of accessories** and then buy it in the computer city.

DIY is good, for home use, the requirements are not very high, plus the display is about 2000 pieces, very good configuration! When choosing, it is not necessary to choose first-line brand hardware, sometimes second-tier brand hardware will be more cost-effective, and the use value is also higher, and the warranty is basically the same. You can practice me if you need to.
