Problem description:
Just bought a computer ~! I didn't know much about the computer, so I bought a repair ~ it seems expensive after buying it? Brothers and sisters who know computers, please give some advice ~!
CPU: Interp4 28/64-bit (2.80HZ) 790 yuan.
Motherboard: Onda 9 15P 670 yuan
Memory: pirate ship 5 12M 345 yuan.
Hard disk: ST80G 420 yuan
Graphics card: Onda 6200 PCJ—E 450 yuan
Audio: rambler 2 1 120 yuan.
Chassis: Jinhetian 8 185 360 yuan
Display: Philip 170S6 1690 yuan.
Thank you all. . . . . .
Analysis:
Now those who sell computers don't earn much on CPU, motherboard and hard disk (20 yuan at most), so don't worry;
Mainly in the chassis+power supply (profit can be as high as 100~200), keyboard and mouse (20 ~ 30);
Graphics cards, monitors (100 or so), but the cost of monitors is several thousand (1500~2000), and computer merchants can't earn 10%, and not many people are willing to do such low-income things. After all, the rent of a moonlight storefront selling computers is thousands (some as high as 20,000), and everyone has to live. ...
But be sure to check whether there are refurbished goods, fakes and bright spots on the display.

All the above prices are reasonable, and some of them are very cheap. ...

It's just that the chassis is a little expensive, so it's good to buy a good power supply. ...
I think the memory was much more expensive when I bought a computer, but now the price is reduced, 555. ...
Overall evaluation: very good.
There are many reasons for "sometimes using it quickly, yes or no", as follows:
One: browse the web, install and uninstall software, etc. This makes the registry information surge. It is suggested to download the magic settings of optimization master or super rabbit to clean up the redundant information of the system;
Second, if you run large-scale software such as 3d maxs and MATLAB, play large-scale games, or multitask (even open BT, Thunder QQ, etc.). ), it takes up more system memory, and 5 12M memory is relatively insufficient.
It is recommended to slim down the system or upgrade the memory (if you have money, you can buy a 5 12M memory).
Third, borrow third-party tools to optimize the system.
Four: the server problem.
Five: There may be computer poisoning or rogue plug-ins. Use 360 security guards to kill viruses and remove them.
It's good to have a good computer. Have fun!
