What is the reason for the large memory usage of the computer?

CPU occupancy, not memory.

Your system is Windows 7, right?

I see you have Kaspersky installed, if it is indeed a 7 system, so far, there is still a little problem with the compatibility of the latest version of Kaba and 7, and scanning can easily cause a certain application to occupy high CPU resources.

There are two ways for you to test your tests:

1. Set the Kaba settings, and in the Options-> Threat and Troubleshooting, set the application directory or application you opened in the checklist. The scan of individual programs will be much lower and less noticeable.

2. When the occupancy is high, you can stop using the caba first to see if it will come down, it should come down in a few seconds.

If this is OK? That's definitely the Kaba problem, and adding exclusions and whitelisting can solve the problem temporarily. It is said that the latest version of Kaba (compatible with win7) will be queried in October or November.

If it's vista, the same, add the exclusion of trusts appropriately!

If you can't see clearly, turn off the ones you don't use first. Take a look at the one that takes up the most and use 360 to see the memory process.

This is normal, and I think you should change to a better computer to use Vista properly

The Vista system itself takes up a lot of memory, and the processes you upload are blurry and can't be seen clearly, so it won't help you.

After the computer is booted up,The system service occupies the memory,GenerallyXP system can account for about 30%,It depends on the software you install,And win7,The system will occupy more memory。 So this is also,A lot of people with small machine memory,Will not upgrade the win7 system,Because the memory consumed is large!

Let me start by talking about your machine, 1G RAM should be a machine for several years. Now the mainstream is 4G memory, and the 2G memory of my notebook is a card, and I can't open too many things. And as soon as you open the win7 system, the direct memory accounts for 60-70

If you compare cards, it is recommended to regularly clean up junk, files, clean and repair disks, and uninstall some software that is not very useful, but occupies memory!

In fact. First, you set the virtual memory automatically, which is the system management size.

Second, you don't care about how much memory you occupy, can you run smoothly? Yes, there is no problem.

Thirdly, if you take up little and empty a lot as you think, isn't it a waste?

The memory of the host is too small or the system is not optimized.

1. The speed factor of the computer system.

The speed of the computer system is determined by the CPU, memory and hard disk addressing speed, the CPU, the hard disk factor can not be changed, but the memory is very different, because the memory we are talking about refers to RAM, which will change according to the number of running methods and applications, if the more memory is occupied and thus affect the speed of our computer, the more memory it occupies, the slower it will become.

2. Optimize the memory of the computer.

There will be a lot of garbage when the computer is used for a long time, when listening to songs, watching movies, and system garbage. You can use software to clean up, or your computer disk needs to be cleaned, you can right-click on the C drive, select Properties, click on Disk Cleanup, and then OK.

3. The role of computer memory.

Memory refers to the fact that the input and output speed of the internal memory is much faster than that of the hard disk. Memory is mainly used to store data temporarily.

Optimize startup items, close some programs that are not commonly used or do not need to be started, and reduce the memory usage. If you have 2G RAM, it is recommended to upgrade to 3G or more.
