The CPU usage of the computer is too high, which causes the computer to be stuck slowly

1. Rule out viral infection.

If there is a virus or horse in the computer, the Trojan malicious program is likely to occupy a lot of CPU resources, especially some stubborn virus Trojans, which have been in a malicious loop activity, infecting all kinds of system files, and occupying a large number of them.

With CPU resources, this situation is easy to appear that the CPU usage is too high, even the high CPU can not withstand the repeated operation of a large number of malicious programs, so if we find that the CPU usage is too high, we should first think high.

Whether it is a virus in the computer, it is recommended that you install such as Kingsoft Antivirus for a comprehensive investigation and killing.

2. After excluding virus infection, we need to start with system optimization, first of all, it is recommended that you optimize the startup item, try to make the software that you don't need to use start automatically without booting, such as some ** software, bank security plug-ins, etc., which can be opened when you need to, and there is no need to start the boot.

3. Close unwanted program processes.

If we find that the CPU usage is high, we can go to the task manager and close some unwanted programs and processes.

4. Optimize registration.

Optimize service items through the registry, you can also optimize the use of CPU resources to a certain extent, for example, when the system checks that the relevant services are turned on, the CPU will be allocated more for its use, we just want to disable this mechanism, the method is as follows:

We first go to the computer registry, then keep only the audioendpointbuilder and rpcss in the numerical data, delete everything else, and then exit.

The above is a simple introduction to the optimization of the relevant services, by disabling the useless function, you can also slightly increase the CPU resources, in addition, we can also optimize other items in the registry.

5. Optimize system services.

In the operating system, many system services are turned on by default, but some are very important and must be run, but some are not important, such as our computer does not have a printer, wireless network, etc., then you can completely turn off the printer function and wireless network system services, etc., which can also save system resources and save more resources for the CPU.

There are several reasons why a computer may run slowly, and CPU usage is just one of them.

If your computer has too many junk files (i.e., the system has been used for a long time, there are too many temporary files and pre-read files, as well as residual information and files left after installing and deleting software), use Super Bunny, Windows Optimizer, or 360 to clean up the system junk files.

There are too many services or programs running after booting, enter the start menu ,-- run - enter msconfig, and cancel all the things that are not needed in the service and startup options.

Scan the entire disk with 360 or anti-virus software to see if there are any viruses or rogue software at work.

PS: If your memory is too small, less than 512M, it is recommended that you upgrade the memory first. If you are still stuck after all of the above, it is possible that your hard drive has too many broken lanes, or there are bad sectors that directly affect the transfer and read speed of data between them.
