If you ask a well-known search engine about why CPU utilization can be 100 percent, then the lion's share of answers, one way or another, will be related to the actions of computer viruses. Unfortunately, this is true. Although, of course, the list of reasons due to which the CPU 100 is obtained, this does not end there.
Let's remember
what is a processor (CPU)? This node of a computer system is a computing unit that performs digital data processing. Sometimes it is compared with the human brain, which, in general, is quite acceptable. If you go to any store selling
computer equipment, then in the windows and in the price lists you can see a huge number of different processors. The difference between one model and another is represented by performance or processing power. In other words, the faster the processor runs, the less time it takes to get the result of the calculations.
The above is much easier to understand by comparison. In addition, it will become clear why CPU 100 loading is sometimes achieved. We will present two processors - a modern, productive and inexpensive budget model. Both the first and the second contain millions of transistors operating at high frequency. The higher it is, the more productive the CPU is, as a rule (other things being equal). Why do you need to know?
When they say that "CPU 100 loading", this indicates that all the processing units of the processor are involved in executing a section of the program code. At the same time, heat generation and electricity consumption increase. One of the reasons that results in 100% CPU utilization is the execution of a program demanding on computing resources on a low-performance processor. Imagine that a child and an adult are instructed to carry a 20 kg bag. Obviously, the first will be exhausted, and the second will do the job "jokingly". Conclusion: “heavy” applications are more rational to run on powerful CPUs.
In order to find out the load on Windows systems, you need to press the combination Ctrl + Alt + Delete and select "Task Manager". Here, the “CPU” column displays the load generated by each program currently running. Sometimes you can see the number 100. CPU usage of this value does not allow other programs to work normally. An exception is a process called System Inaction.
For him, the norm is a load of 98-99%. In this case, the HLT command is executed cyclically or the SpeedStep mechanism is activated, aimed at reducing energy consumption. At the same time, other applications gain access to computing power in full.
If a third-party program constantly creates maximum load, then first you need to check it for viruses. To do this, in the Task Manager, click on the desired application (with 100% load), open its properties, find the path to the file. Now you should open an online virus scan site and check the “suspect”.
If everything is fine, then you need to search the Web for information, for which you need an ongoing process. For example, it may be a device driver module that does not work correctly. In this case, you need to update it to the new version.
