Can I change my computer? Swap with the merchant .

Unless you know the person who bought the computer very well! He'll find a way to change it for you! Otherwise, you won't be able to pull it! It's not worth it!! You're crying even more!

I'll give you a solution! It doesn't have to cost a lot of money!

Go change a CPU fan for dozens of quick money!! If you want DDR2 memory on your computer, add 1G of RAM! Not even two hundred!

If it's DDR1 generation, go add a graphics card about 300 and generally the game can be done! The hard drive will have a sound, and mine will be the same! Just get used to it!

In the future, there will be money to pull in the change of hard drives! Because which thing is really expensive, the 160g WestJet 7200 rpm 8m cache is 450 to 500

It's okay! If the quality is not good, you can go to the Industrial and Commercial Bureau, in order to safeguard the interests of consumers, we should stand up and reason, or you can go to 1818** or go to the "give an explanation" column. If I bought a computer and it was still not good, I would be angry and have a thought, I don't want to return the money to me.

Something back to you. There are two options: one is that you talk to the merchant, if the merchant does not have a good answer, then I'm sorry, I can only find some ** to talk to the business of the law. You can go and find it"Xiaoqiang**", "Help the eldest sister", "1818**eye", you can also find Wenzhou's "people to talk about the news", "idle mother-in-law, idle business".

Brothers! I'm sorry to tell you, no.

The replacement period has passed!

Send a message on the Internet or somewhere to sell it.

Add some money to buy an assembled one!

Kindness. I can't change it.

The first is to pass the replacement period.

The second is not such a kind business.

Either you upgrade the computer yourself, or as the upstairs said, 2 hands and buy a new one.

When the second-hand goods are disposed of, make a new one yourself

The speed of a computer depends mainly on the CPU, memory, graphics card.

1. In terms of CPU, the CPU is recommended to be upgraded to Core i5, i7 speed, due to the upgrade of the first-level and second-level cache, the computer has accelerated the processing speed.

2. Memory, that is, the memory of the computer, it is recommended to increase the memory of the computer above 4G memory, so that the computer cache space is more, which can speed up the running speed of the computer.

3. The graphics card is the display of the computer in charge, and it is recommended that the graphics exist above 2G, and many large-scale software games need a better graphics card to render better picture quality effects.

4. Other upgrades, such as replacing SSDs, can greatly improve the speed of the computer.

I don't understand what you're asking.

This question is called how embarrassing I am to help people change (upgrade) their computers, and my Chinese name is called -- human.

If you mean to change hardware, generally desktops, you can upgrade the CPU, graphics card, memory, hard drive, etc., for better performance.

If you are referring to a change of software, you can change and reinstall the system for a better experience.

Can you learn how to ask questions before you come up and ask questions, and what are you asking? Can you express your thoughts clearly?

It's you who renew it...

Changing computers involves the following analogy:

Changing the host computer system is equivalent to changing the computer.

The display screen was changed, and the computer system did not change in any way.

Reinstalled the system, did not replace the computer, but the system changed completely.

Pretty much Lenovo, Dell, a little better Sony, Apple.

If the configuration is low and slow, you can consider changing computers.

Purchase a new unit or a complete replacement. It can also be second-hand.

System disks, PE boot disks, etc., and patience.
