Everyone was faced with a situation where PC performance drops sharply at the most crucial moment. First, the response time increases, and then the computer completely hangs. Why is this happening? The causes of disruptions can be very different and have a different nature. This article will be useful to all those who regularly encounter a similar problem, and will help to cope with a stressful situation.
To establish the reasons why the computer hangs, and also to eliminate them will help diagnosing the software and hardware, testing the performance of the machine using standard tools. The main thing is to determine what is wrong with the system: malfunctioning of low-level hardware devices, virus infection, overheating, etc.
Computer is being very slow. Why is this happening and how to be?
For the most part, people who are far from IT technologies face a similar problem. They are of little interest in how they live and how their PC breathes. Without thinking about the consequences, they visit sites with a dubious reputation, while they do not install anti-virus protection, and also install software and plug-ins from an unknown manufacturer. Such users also do not think about the prevention of a computer or laptop, and you need to regularly clean and replace the thermal paste.
But, to my great regret, conscious and experienced PC users who have a trepidation and very careful attitude to their machine also face a similar problem. Yes, no one is safe from this. Sometimes crashes occur even if a modern operating system is installed that provides good performance. For example, Windows 7. Why does the computer freeze in this case? The most popular reason is a violation of the installation process of software products as a result of an unexpected shutdown of the system. If problems with computer performance have fallen sharply, like snow on their heads, then it is necessary to start the process of restoring the OS to one of the earlier states.
Contamination is one of the most common causes of PC freezes.
During operation, the cooler draws air from the environment in order to remove heat from the elements of the motherboard. It is clear that the smallest particles of dust and all kinds of chemical compounds fall into the laptop case with air. Dust and dirt settle on the motherboard, clog the radiator holes. As a result, the electronics overheat and the computer freezes. Why not use another type of cooling system? The answer is very simple - it is not economically feasible. Alternative systems have long been developed and put into production. However, they are installed only on very expensive and productive machines.
When should I clean my computer from dust?
The first signal indicating contamination of the cooling system is the continuous and very noisy operation of the cooler. In normal mode, the cooler works quietly and can even turn off for a while.
To restore the performance of a dirty PC, you must contact a service center. Experts quickly and for little money disassemble, purge and clean the laptop. Some organizations offer cleaning your computer as a free bonus when providing other types of services. The service center will also change the thermal paste under the chips of the processors and the north and south bridges of the motherboard, which will significantly increase the heat sink efficiency.
Virus attack
One of the most common causes of a sharp drop in productivity is attacks on the system of all kinds of virus software products, the hidden work of trojan programs. And vulnerable in this regard are devices under any operating system, and not just under Windows. Why does the computer freeze due to the operation of such programs?
The fact is that such programs select a significant share of capacity for their needs. Hackers even came up with such programs that can quietly for the computer owner to perform complex and resource-intensive mathematical calculations in the interests of third parties. For example, computer hardware can mine (cryptocurrency) cryptocurrency, and the PC owner will not even suspect it.
Fight against viruses
The easiest and most effective way to fight viruses is to reinstall the operating system. But not everyone can decide on such a desperate and radical step. The fact is that for many years almost every year they saved important information on their hard drive, set up a computer for themselves. Such concerns are common to inexperienced users. In fact, there are methods and methods that allow you to save all the important information when reinstalling the OS.
Sometimes, before starting to puzzle over and find out why the computer hangs, it is worth installing an antivirus program and conducting a full scan of the system. In most cases, the problem is removed and the original performance is restored.
Computer freezes up
In the event that the PC loads very slowly, and the rest of the time there are no complaints about its operation, the thing is, with a high degree of probability, is that a large number of programs are installed at startup. Such symptoms often have computers running Windows 7. Why does the computer freeze? The reason in this case is quite understandable: simultaneous requests from programs to the processor are a kind of hardware stress test. The processor performance of a regular home computer is not so great that it can simultaneously work with so many programs.
Restore computer fast boot
Now it’s clear that the main answer to the question: “Why does the computer freeze?” - elimination of the cause of this trouble. The restoration of PC performance in case of slow boot is simple:
- run the built-in utility msconfig.exe (the easiest way is to perform the operation of the same name on the Windows command line);
- go to the “Startup” tab, deselect check boxes opposite the names of all software products, the launch of which at the same time as the OS is undesirable;
- to restart a computer.
If you can’t fix the problem yourself
In some cases, the computer freeze cannot be resolved by the listed methods. This is possible if the problem lies in the damage or failure of any element of the hardware of the computer. And if the computer continues to hang even after reinstalling the operating system with all the necessary official and licensed drives and distributions, then you should contact a specialized workshop for repairing personal computers. Masters in such organizations have extensive experience, and in most cases they can immediately diagnose a malfunction.
