Why does the computer slow down, and what to do in this situation?

Most hardcore PC users sometimes face a problem when their computer starts to work very slowly, in other words, slows down. And who will like it? Who wants to sit for hours in front of the monitor, waiting for when the program will load? The answer is obvious: nobody will like it! But do not despair. If there is a problem, then there is its solution. In this article we will try to understand why the computer is slowing down and what to do in such a situation.

Possible reasons:

1. Overheat. If your PC is purchased not so long ago, and you have never cleaned it, then perhaps this is the problem. Dust that accumulates on the internal parts of the system unit or laptop causes overheating. You can understand this when running demanding programs, they will be very slow to load, and there will be a lot of noise when the processor is running. Sometimes the overheating protection system may even work and the computer will shut down. There is a very useful AIDA program, with which you can monitor the temperature of the processor. And if it is without load will be more than 50 degrees, it means that it's time to think about cleaning. So, you already know why a powerful computer is slowing down, now you can proceed to fix the problem. In this situation, you need to disconnect the PC from the network, remove the side cover of the system unit and carefully vacuum all parts without touching them. Pay special attention to the fans, it is on them that most of the dust accumulates.
2. Many programs work simultaneously. Yes, the processor is difficult to cope with a large number of running applications. This applies to Internet pages in the browser. If you have many open tabs in your browser at the same time, the CPU speed drops dramatically. To solve this problem, close all unnecessary programs and Internet pages.
3. A lot of "garbage" has accumulated. Each user involuntarily clogs the registry, downloading, and then deleting programs and files. Yes, this is another reason why the computer slows down. And what to do in this situation? Of course, clean the registry and perform disk defragmentation. There are quite a few programs that will help you do this: "Advanced SystemCare", "CCleaner" and others. And as for the defragmentation, it can be done like this: "My computer" - "Disk properties" - "Tools" - "Run defragmentation".
4. The presence of viruses and Trojans. This is another common reason why the computer began to slow down. To eliminate this, you need to install an anti-virus program on your PC, with which you can easily fix the problem.

So, now you can easily find out why the computer is slowing down, and what to do in this situation. But this is not enough! You still need to know how to behave properly if your PC is frozen and does not react to anything. Do not unplug it from the network, but try to be patient. Usually it takes about 15 minutes to download a resource-intensive program. If possible, then terminate the running applications using the "Ctrl" + "Alt" + "Del" keys, by pressing them simultaneously. A window will appear on the monitor where you can finish all running programs without waiting for them to be fully downloaded. But if this command does not work, then you have to take extreme measures and restart / shut down the computer with the button. But then, unfortunately, you risk losing all unsaved information. I hope, thanks to this article, the question "why the computer slows down and what to do in this situation" you will never arise.
