How to choose the right model for computer memory

You add, look at the cpu model of your computer, according to the cpu model you can distinguish the type of memory you have, check the cpu method: my computer right-click properties can be seen, there are many ways to judge the memory, for example, some people say that you can use software to see, but it is estimated that you are not very familiar with the computer, so in case of a purchase error, you have to go back to change, go back to change the price, not very suitable, and open the case to view, but friends who are not very familiar with the computer or don't try, the gains outweigh the losses.

Insufficient virtual memory is generally caused by viruses, or the remaining space of the C disk is relatively small, you check the space of the C disk, if the remaining space is small, delete some things on the desktop, if the things under the windows and pro folders of the C disk are not deleted, it may damage the system.

The reason for the computer card is divided into hardware and software, if it is a software aspect to try the system, if the hardware aspect needs to look at the configuration of your machine and detect whether there is hardware damage, mainly view the hard disk, use the start - all programs - accessories - system tools - disk scan, if you can defragment, generally this hard disk is no problem, if you can't tidy up, you can consider formatting from the new installation system, see the effect and then determine whether the hard disk problem, in addition from the system to do the system and format will lose disk data, There are important files backed up in advance.

Free antivirus software is best determined according to the computer configuration, some computer configurations are not very high, and the configuration required by the current antivirus software is not low, so it has to be based on the hardware environment, Kaspersky Internet Security is good, I am using it, there are many free keys on the Internet, you can import it, and you can also consider using it if you have Kingsoft.

Third-party software such as Optimizer or CPU-Z can see the capacity (256M, 512M, etc.) and frequency (DDR 400, DDR2 667, etc.) of the memory. You can open the case, directly ** the English on the memory module, on the search, you can know the brand, for example, Kingston is Kingston, Hynix is Hyundai, A-Data is ADATA, Apacer is Apacer and so on

After you know everything, let's go to the computer city and buy the same one, haha.

The computer card is basically caused by the lack of memory, and there is also a chance of poisoning.

Free antivirus software is hard to find,Rising will launch a free three-month or semi-annual version from time to time,I used to go to a **** Rising called Sun Man,He is free**,The moderator will basically launch a new data package every day,Internet **Update package can。

There is no model number of memory modules, and there is generally only a difference in memory size. Ask someone from the computer store to come to help you install it, otherwise you can move the host computer yourself and ask him to install it. Computer cards are generally a problem with small memory, and it may also be a virus.

You don't need to actively use the memory module, and the memory will be automatically expanded when installed on the computer.

Or put on a 360

If it is DDR2 memory, buy two directly, DDR2 800 1G memory plugged in** is about 150 yuan; The memory module can be plugged in directly;

There are many reasons why the computer is very stuck: it may be that the CPU usage is high, or it may be that the memory is too small, it is recommended to determine through the task manager, the virtual memory is too small, please set it to the system management size;

Check what the memory module on your machine looks like): This hardware information can be checked using the optimization master or search for a hardware on the Internet to view the software, Rising has a free version, you can go to Google Software Selection**.

Your next Windows optimizer to check what the memory module on your machine looks like is better than buying the same model on the line of free antivirus just a Rising but not very easy to use.

Looking at the memory, mainly looking at its frequency, DDR1 (first generation) has 226 333 400 DDR2 (second generation) has 533 667 800
