Here are 20 tips: please indicate that Baidu knows the installed ID: AOL1027.

1, the purpose of computer DIY is to build a computer with the highest cost performance, the strongest performance and full of personalized use, which is the fundamental purpose and spirit of DIY. So please tell the budget, purpose, use requirements and hardware requirements as accurately as possible, DIY will play its greatest advantage ~ ~! ~

2. Prepare two configuration sheets, one with the price for yourself, and the other without the price written on the blank sheet in the assembly workshop. Take the configuration sheet to the largest computer store in the computer city, find three stores, and let them calculate the money according to the configuration. They all have blank configuration tables. You write down the configuration list, not the price, and let them bid first. You have to cut lower, cut higher ~ ~! ~, CPU, motherboard, memory quotation is lower than my 40 yuan, be careful. Other parts may be surprisingly high. There is also a great possibility of fooling the store, and there may be fakes. Be careful ~ ~ (generally, the price changes slightly around May 1,1,New Year's Day and Spring Festival. Generally, these four time periods are price adjustment periods, with a slight increase before the holiday and a price reduction after the holiday);

3. It is best to find a listed motherboard, CPU, or graphics card agent to install, so as to ensure that the price of at least one accessory is the lowest. Otherwise, everything will be outsourced, and the price will be higher if each company earns you a little. Also, if you buy the goods they represent in their store, their enthusiasm will be high. Find the lowest one and buy it all;

4. When the accessories are brought here (unopened), you have the right to ask for inspection first, which is an industry rule requirement that you can confidently ask for, hehe! First of all, look at the packaging, integrity, whether there are signs of unpacking, fouling and so on. If there is, change it, because it may be repaired or fake! Then, carefully check the model and core parameters. There are different symbols or fewer symbols on the main model! Everything was ready when you left. Try not to leave the site during installation to avoid being replaced. It is best to go with two people, so that you can take care of it!

5. Memory and hard disk: Kingston has the most fakes in the memory market (90% of Kingston in use are fakes). If you buy a fake computer, the screen may be unstable. It is generally recommended to switch to Yu Zhan (with good stability) or Wei Gang. Shang Weigang's memory does not match with Yingtai's motherboard, and it is also unstable, hehe ~; Western Digital is generally recommended for hard disks. Seagate has a lot of quality problems recently, and the latest generation of 12 seems to be ok, but the overlord clause after sale is also unacceptable, which is almost equal to no after sale;

6. Power supply: it must be stated that it is rated power, which is easy to ignore. Many stores pretend to be Fengli, so we must make it clear that the goods will be confirmed after they are brought here; Also, if the voltage there is unstable or there is frequent sudden power failure, it is recommended to use UPS power supply, about 200-500. If there is a sudden power failure, it can maintain normal operation for 3-6 minutes, and it is very important to save data. Please indicate that Baidu knows the installed ID:aoling 1027.

7. Talk about monitors, Samsung, Philips, LG, etc. It used to be really good! Now these brands are also OEM in Chinese mainland and Taiwan Province Province. You have bought domestic products for a long time, so there is no need to give others hundreds of brand fees! Domestic monitors can already compete with these brands, such as Great Wall, AOC TPV, Emerson, Acer, Hanshiqi and so on. , can be completely replaced, you can buy a bigger one at the same price! Game monitors are generally recommended to be no more than 24 inches, and about 22 inches is more suitable. Otherwise, it's easy to get dizzy, especially FPS (first person shooting) and action games!

8. Don't ask them to "recommend other accessories" for various reasons, such as out of stock ... They will generally suggest the brand they represent. Unless he represents a first-line or top-level second-line brand, the hardware model and price are reasonable, don't change or ignore him. In general, they recommend other parts because of their high profit and average performance, especially the four major parts (U, motherboard, graphics card and memory). Needless to say, CPU is Intel or AMD. Here, I mainly talk about domestic motherboards and graphics cards: first-line motherboard brands: Gigabyte, MSI, ASUS, and second-line motherboard brands: Yingtai, Huaqing, Jiebao, Mei Jie, Elite, Spartak, Shuangmin, etc. Their performance and workmanship quality are almost the same as those of first-line motherboards (whether they are genuine or not, they are very easy to use), but their popularity is low, but their prices are cheap and cost-effective. They are worth buying if the cost is tight. Graphics cards: First-line Sapphire, Dylan Hengjin, Asus, Gigabyte, MSI, Sotai, Jing Xun and other second-line graphics cards: Colorful IGAME series high-end cards, Inch (screen and high temperature problems have not been well solved), Elsa, MG (overall good) and so on are all popular graphics cards; Other qualities are average. Of course, the advantage of this board is that it is cheap. If the budget is not enough, I suggest you choose.

9.CPU selection. It is best to choose Intel's CPU for office or office-cum-game computer, which is suitable for many softwares (very important) and runs stably; If it is a home online game machine, try to choose AMD platform, which has high cost performance, high frequency and high speed, and high platform performance. If the game machine is only turned on occasionally, it is strongly recommended to use a dual-core CPU with high frequency instead of 3, 4 and 6 cores, because the mainstream games are optimized according to the dual-core U at present, and the dual-core U is not much worse than the U with more than 3 cores in game performance, and some games are even better and more affordable! In addition, there are only 3 or 4 games optimized by 4-core U (Go-kart, Supreme Commander, Tomb Raider 8, World of Warcraft). Even if the game is optimized by 4-core U, the dual-core frequency can still be played above 3.0G, and the special effects will still be on ~ Although it will be a trend to optimize by 4-core U in the future, it will not be widely popularized in the next three years, so the money saved can be used on the graphics card (or added to the motherboard, memory and hard disk) , hehe, it seems a lot. So don't blindly pursue 4 cores, especially the entry-level low-end 4-core CPU. In the future, the game will be optimized according to the 4-core U, and the requirements for the 4-core U are naturally high. It is estimated that entry-level 4 cores are not enough. Suitable for friends who don't play games with a budget of about 3000 yuan. Of course, if it is more than 3 cores, it is recommended that the CPU with more than 3 cores is the best, and the more cores, the better.

10, the difference in motherboard selection, A platform with board and I platform with I board, needless to say, is a common phenomenon of the same platform: AMD platform: if you choose an independent graphics card above HD5550, it is recommended to choose motherboards with independent chipsets such as 770 and 870, which will have better stability, compatibility and performance; Don't choose motherboards with integrated graphics chip sets such as 880 and 785. In addition, it is meaningful to display the display below HD5450 if the vehicle integrated display and the independent display group exchange fire. I platform: integrated graphics motherboard G3 1, G4 1 and other chipsets; Independent chipset motherboards P3 1, P4 1, P43, P45, H55, P55, etc. Let's talk about the difference between 770 and 870, and the difference between H55 and P55: there is little difference between 770 and 870. 870 is a new motherboard chipset, which is new in 1, SATA3,2 and USB3.0. SATA 3 mainly doubles the transmission speed to 6Gbps, which is only a theoretical value. In fact, the speed of SATA interface sending information is 600 MB/s, and USB3 can really greatly improve the transmission speed, which is extremely rare for ordinary users to use together when a group of disk arrays or multiple card readers are used together, which is actually meaningless; The difference between P55 and H55: 1, which supports graphics card crossfire and SLI, 2, RAID (in short, RAID is a technology that combines multiple independent hard disks (physical hard disks) in different ways to form a hard disk group (logical hard disk), thus providing higher storage performance and data backup than a single hard disk. )。 H55 motherboard provides a video output interface, and you don't need to buy a graphics card with I3 (some H55 motherboards consider independent display, and there is no output interface, so please note if you don't buy independent display); P55 is used for crossfire between two or more graphics cards, and P55 is also used for RAID of two or more hard disks. H55 is used for a graphics card and a hard disk, and H55 is also used for a hard disk without a graphics card. It is expected that you can choose to upgrade your computer in the future.

1 1, the choice of graphics card: general home Internet access and 2D games can completely integrate graphics cards; Large game consoles, A cards beginning with HD and N cards beginning with GT can be used. Of course, rice A says A is good, and rice N says N is good. At present, a large number of forums in China are full of n guns. Briefly talk about how N card overclocked, how stable and how strong it is, and compare it with the default of A card, which leads to the general view that N card is suitable for games and A card is suitable for movies and videos. This statement is wrong. Businessmen are very clever. If they can overclock, they will sell it to you at a higher model price, so they are not philanthropists. Overclocking is extremely risky, and it is not guaranteed if it is broken. Compared with HD5770 and GTS450 of the same grade, the 5770 is a little stronger, the games that GTS450 and 5770 can run and the games that GTS450 can't run have improved performance after overclocking, but the temperature is high, the noise is high, the stability is poor, the life is short, the power is greatly increased, and the power supply may not be enough, so it may be necessary to replace the power supply. The grade of A card and N card is the same (even if it is one and a half grades apart). In the eyes of people who know hardware, there is no such thing as complete victory and seconds kill. These words were said by the gunman, because even if the focus is different, the gap is subtle. Some people say that the A-card driver is not a weakness, and the driver has been improving, which is not a problem at all. Personally, I am neither a meter nor an n meter! From the user's point of view, the pursuit is the continuity and shock of the picture. As mentioned above, at the same level, the continuity is basically the same. In terms of shock, it mainly refers to the high definition, high rendering details and bright picture. These are the advantages of A, so A card is generally recommended. Furthermore, professional graphics cards are generally recommended for professional drawing, professional modeling and drawing. Sapphire and Lee Tae are both available, and the price is relatively expensive. Game cards starting with GT and HD are not recommended, especially those starting with GT. HD is not a particularly professional 3D drawing, but it can also be considered. Drawing in the office is also a game, hehe ~

12, random gifts, generally the lowest performance and cheapest goods, such as cameras, mouse and keyboard, headphones, speakers and so on. Remember to ask them for money when it is tight;

13, the machine maintenance workshop is responsible for installing the system and common software, and installing them during installation. Remember to install Master Lu or other similar software. After installing the system, run Master Lu to check the hardware to see if the configuration list is consistent!

14. Ask for the invoice (legal person, +5% tax) or receipt (private person), and keep the packaging and warranty card (write the warranty date);

15, part of the price is ZOL, JD.COM Online Mall, Newegg, Yixun or Netneighbors, so the actual total purchase amount should not go up or down.

Exceeded 150 yuan. LZ can be purchased by comparison. Online shopping is very mainstream now. The online shopping malls listed above are all formal. There are three bags of genuine licensed goods, and there are invoices after sale. Shops with good reputation, large turnover and perfect commitment on Taobao are also worth considering. There are still many people who don't believe in online shopping, which is a bit out of line:) (JD.COM price features: CPU is expensive; Some models of graphics cards are expensive and some models are cheap; Motherboard, chassis, power supply, monitor, CD-ROM drive, keyboard and mouse are cheap; Hard disk and memory are slightly more expensive; Second-line brand products are slightly more expensive. Net neighbors and new eggs are roughly the same)

16, the configuration list is basically complete, and the keyboard and mouse cover is still very important, especially for the game machine, so there is not much difference in performance compared with the configuration list without the keyboard and mouse cover;

17, the compatibility and stability of listed accessories are very good, and each accessory has no bottleneck, so it can give full play to its functions! Temperature control and noise are low-temperature and low-noise accessories. The quality is stable and durable. At the same time, choose accessories with large online evaluation and good defect-free bad evaluation to ensure the quality and use requirements of the whole machine to the maximum extent!

18, the price, the listed price can basically be obtained everywhere, and the final total price fluctuates little. It is not the so-called channel price, delivery price and other prices that cannot be bought at all.

19, always remember that you are the customer and you are God! The most commonly used trick of the store is that it is out of stock, and any customer bullying behavior such as price increase and missing or replacing parts can be tolerated. Please indicate that Baidu knows the installed ID:aoling 1027.

20. If you are interested, you can try to install it yourself, so you will have a very intuitive understanding of computer hardware! Each accessory has detailed installation instructions and charts, and the interface has a foolproof design. All you need is a Phillips screwdriver! The only trouble is wiring. You can ask a friend for help, or find a network manager who can install the machine. Paying 50 yuan can give you a good connection system, hehe!

If you have any questions, please leave a message. Happy installation ~ ~! ~
