Computers and mobile phones are similar. Some software does not really quit after shutdown, but secretly runs in the background, which will also occupy the computer memory and cause the computer to become more and more stuck, so just call up the task manager directly and click finish the task.

Second, clean up the disk fragmentation garbage:

As we all know, computers will produce a lot of garbage and disk fragments during operation. If it is not cleaned up in time, there will be more and more debris and the computer will be slower and slower. But some rubbish can be cleaned by computer management software, and the method is simple.

Third, replace the computer hardware:

In fact, the first three methods can greatly improve the running speed of the computer, but the best way to improve the space is to replace the existing hardware. The hard disk of the old computer is badly worn. Replacing the new hard disk can greatly improve the running speed of the computer!

Fourth, reinstall the system:

You know, in some old computers, some system garbage is difficult to remove. The most effective way to solve the computer speed is to reinstall the system. After reinstalling the system, the system garbage will be removed together, and the computer will not be stuck again.

Extended data:

Reasons for slow operation of computer system:

1, too many startup projects:

Because some programs are self-starting projects, they will automatically start with the start of the computer, which will occupy system resources and cause the windows system to run slowly.

2. Too much disk fragmentation or disk garbage:

In the process of windows running, a large number of junk files will be produced, and at the same time, a large number of disk fragments and garbage will be produced. If not handled in time, it will affect the running speed of windows.

3. Disk free space is too small:

After the windows system is installed, the default is to store the user data in My Documents on the system disk, and there are many softwares installed by users. The default storage is the system disk. If the user does not choose a storage place when installing, the space of the system disk will be less and less for a long time. The system disk space is small, which will inevitably cause the system to run slowly.

4. Incorrect firewall or antivirus software settings:

Firewall and antivirus software are real-time monitoring software for files and processes. If it is not set properly, it will increase the burden of system operation and lead to slow system operation.

5. The system file is damaged or lost:

After the system files are lost or destroyed, the symptoms are slow operation, frequent errors and serious crash.

6. Computer virus or Trojan horse program:

Computer viruses or Trojans often run quietly in the background, occupying system resources, and then leading to slow system operation, especially worms and Trojans.
