What's going on with cpu 100%?

cpu 100% refers to the CPU usage rate of 100%, which means that the application has fully occupied the CPU. No other applications can be opened on the computer. Running the application has reached the maximum value that the CPU can withstand. It is recommended that users Close the app now. The impact of excessive CPU usage: 1. It is easy to display errors or connection problems after opening a web page; 2. The system application software is easy to crash, causing the computer to not operate normally; 3. It affects the system speed and the computer will slow down; 4. Being fully loaded for a long time may damage the CPU chip and cause the system to crash.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

cpu 100% refers to the CPU usage rate of 100%, which means that the application has fully occupied the CPU. No other applications can be opened on the computer. Running the application has reached the maximum value that the CPU can withstand. It is recommended that users Close the app now.

Excessive CPU usage will have the following effects:

• 1. After opening the web page, it is easy to display errors or connection problems.

• 2. System application software is prone to crashing, causing the computer to fail to operate normally.

• 3. It affects the system speed and the computer will run slower. At the same time, if the CPU is fully loaded for a long time, it will bring a lot of heat and accelerate the aging of peripheral hardware.

• 4. Being fully loaded for a long time may damage the CPU chip and cause the entire system to crash.

cpu 100% reason

Reason 1. Hardware aspect

Hardware aspect is one of the main factors. If the computer The configuration is too old. No matter how you optimize the system, the computer's CPU usage will be too high.

Solution: Solve it by upgrading the hardware.

Reason 2. Software aspect

The software aspect involves system problems. For example, the system is too bloated, too many programs are opened, and viruses will cause excessive CPU usage.

Solution: Mainly through virus scanning, system optimization, turning off startup items, avoiding opening too many programs, etc.

If there is a virus in the computer, the malicious program will occupy a large amount of CPU resources. In this case, it is easy for the CPU usage to be too high. Therefore, if you find that the CPU usage is too high, you should first check whether the computer is infected with viruses and use anti-virus software to conduct a comprehensive scan and kill it.

Extended knowledge: The main function of the CPU

1. Processing instructions, which refers to the execution sequence of instructions in the control program. There is a strict sequence between the instructions in the program, and they must be executed strictly in the order specified by the program to ensure the correctness of the computer system.

2. Execute operations. The function of an instruction is often implemented by components in the computer performing a series of operations. The CPU should generate corresponding operation control signals according to the function of the instruction and send them to the corresponding components, thereby controlling these components to act according to the requirements of the instruction.

3. Control time. Time control is to implement time timing for various operations. During the execution of an instruction, what operations are performed at what time should be strictly controlled. Only in this way can the computer work in an orderly manner.

4. Process data, that is, perform arithmetic operations and logical operations on data, or perform other information processing. Its function is mainly to interpret computer instructions, process data in computer software, and execute instructions.
