The computer hangs tight, Windows 7 stops responding to any commands, is it even impossible to open the task manager? Such problems appear quite rarely. I must say that a computer is a rather complex system, and its performance depends on a huge number of factors. The article will consider the main ones. After reading, you will learn how to cope with most of the problems that lead to "freezes."
Viruses
The first answer to the question of why the computer freezes tightly is the simplest and most common. It is possible that uninvited guests settled in your computer who are well disguised. Usually viruses not only threaten the security of the system, but also noticeably load computer resources. Sometimes this load causes the computer to freeze.
Everyone knows how to deal with such misfortune. It is enough just to install any anti-virus program, update its databases to current ones and perform a full computer scan. It did not help - call the task manager and check the processes for suspicious ones. Also, it will not be superfluous to look at startup, by entering the name of the utility "msconfig" in the "Run" window.
However, if the computer freezes tightly after turning on, it will not work to install new software, and even more so to check the PC. In this case, use any antivirus distribution that can create a bootable USB flash drive or CD.
Overheat
Releasing each new model of the device, manufacturers are trying to make it "more sophisticated" than the previous one. And this requires more power. The latter, in turn. increases heat dissipation. For some time, the standard cooling system does its job, but after a while its efficiency decreases - as a result, the computer freezes tightly. What if a similar misfortune happened?
Dust that cannot be removed is clogged in radiators and interferes with air circulation. Settling on a cooler, dust masses slow down the speed of rotation of the screw. Previously, such problems led to the failure of the device. Today, fortunately, computers have become smarter, the processor or video card will not warm up endlessly. Modern devices have the ability to exchange data with the motherboard, entrusting it with responsibilities for temperature control. As soon as the values reach a critical point, the controller first tries to unscrew the cooler screw, if this does not help, the system slows down the device, reducing the voltage. Soon, the computer hangs tight.
To prevent such troubles from happening, remember a few simple rules:
- From time to time, purge the cooling system of the system unit with compressed air or vacuum.
- Regularly check the operation of coolers (there are many programs for this).
- Periodically change the thermal grease (after some time it dries up).
- Clean dust filters on a common fan.
Very often, because of this problem, the computer hangs tightly in games or other graphics applications. To check how much the components of the computer are heating up, you can download some program. Fortunately, on the Internet, there are a lot of such.
RAM problems
RAM is the most important element of a computer, which has a very big impact on its performance. The normal operation of RAM depends on compatibility with the motherboard, with the BIOS, with other installed brackets. An insignificant failure, the smallest factory defect - and the computer freezes tightly when turned on, not wanting to work even with low performance.
If you are going to increase or change the “RAM”, fully study its characteristics, go to the website of its manufacturer and the manufacturer of the motherboard in advance, study what speeds are supported, what tests were carried out and whether it is recommended to use the devices together.
If the computer hangs tightly before changing the configuration, you can check whether the RAM fails using Windows 7. Just click on the “Start” button and type in the search box the line “memory checker”. During the execution of the procedure, the program will display all errors if they were found. There is only one recommendation: there are errors - change the memory.
HDD instability
A hard disk is a device on which absolutely all data is stored (both user and system). Accordingly, Windows refers to it all the time, reading and writing do not stop even for a minute. And this means that system performance directly depends on the speed of this component. Over time, “broken” clusters and unreadable sections may appear on it, which will lead to malfunctions of the system. Often, because of this problem, the computer freezes tightly on the Internet, because during surfing the browser constantly writes and deletes many small files.
Recovery of a damaged HDD
If the HDD is worn out, you need to check it with special software tools that will find all the bad sectors and mark them as inactive. The OS will stop using "bads" and will stop hanging. To check, run the command line by entering the name of the program in the window “run” - “cmd”. In it, run the command "chkdsk [drive letter]: / f / r" for each partition.
Experienced users can determine the status of the HDD by the sound of its work. If he starts to click or whistle, most likely the equipment is faulty and needs to be replaced. Be vigilant, often if the hard drive begins to “crumble”, it will soon fail, and it is very difficult to recover data from such a device. Also, if the computer freezes tight after turning on, there is a high probability of hard disk wear.
Incorrect BIOS setup
If the computer hangs tight after turning on, very often the reason for this system behavior is incorrect BIOS setup. Someone may think that an ordinary user should not even try to fix something, you need to contact a professional. But nevertheless, the computer hangs tightly - what if there is no way to call a specialist?
If you approach the BIOS configuration with care, a beginner will also cope with this procedure. Examine the complete information about your computer, and especially about the motherboard. Typically, such data is easily located on the official website of the manufacturer. Find out which parameters are most important, what they are responsible for. When working with the BIOS setup utility, never change many parameters at once. First, change a few, reboot, check the computer. Only then continue editing. Separate mention is the item that is in every BIOS - “Load Fail-Safe Defaults”. He brings all the parameters to optimal - according to the developer.
Sometimes on the website of the manufacturer of the motherboard you can download and install a new version of the BIOS. Never refuse such a procedure. Often updates update critical errors and improve stability. It is likely that after installing the new version the hangs will disappear. The main thing is to read the instructions in advance.
Windows Services
In the operating system, a large number of services are working all the time, enabled by default or added during operation. The system can function normally without most of them. If some service does not respond or takes too much processor time, the computer freezes up.
To see which of them are in the system and which are running, open the administration window ("Start" - "Control Panel" - "Administrative Tools") and double-click on the "Services" icon. To get comprehensive information about a particular service, double-click on its name.
First of all, pay attention to those that start automatically. The loading method is indicated in the "Startup Type" column. The editing rule is one - if you do not understand the description, do not disconnect the component, but learn more about its operation from the Internet. Try to check the stability of the system after each individual manipulation.
Processes and programs
Each program starts its own process (sometimes even not one) if it enters an endless cycle or malfunctions, while the computer does not always freeze up, Windows 7 still tries to independently shut off oxygen to non-responding components. Revealing a hung element is very simple - it usually takes the lion's share of RAM and almost all of the processor time.
Solving the problem using the task manager
You can view the list of running processes in the task manager window. Press the key combination “CTRL + ALT + DEL” on the keyboard. If you are sure that some program does not carry a payload, but at the same time takes 90-100% of the processor time, feel free to finish it (by pressing "DEL" on the keyboard or by calling the context menu). Also from here you can go to the program storage location. This will be useful if you do not understand exactly what you are interrupting.
Checking processes is not always the best solution, but this procedure can often help if the computer freezes periodically. Remember that some programs can load the processor one hundred percent in the most active phases of their work. However, the hanging utility will not stop using the maximum resources, and the one that performs its functions without failures will again pass into passive mode after some time. Also, do not try to complete the process called System Inaction. It is used to poll other programs and system resources, and the variable in it displays not the processor load, but just the remaining free power.
