Long work at the computer can take you a couple of extra minutes to complete Windows work. Lifehacker already wrote about one of the common ailments in which the computer turns off for too long due to an overgrown paging file. operating system. But sometimes even more severe cases happen - Winda does not turn off at all. In this article, we will tell you how to calculate the cause of Windows 7 freezing when shutting down or, conversely, loading the operating system.

Introduction

Let's figure out which of the processes brings Windu into a thoughtful state. And the built-in windows function a detailed report on the status of startup, shutdown, login and logout. No wonder if you haven't come across this report. This Windows setting is disabled by default and can be enabled using the Registry Editor.

Working with the Windows Registry

To launch the registry editor, simply type in search line Windows regedit.exe.

Navigate the folder tree to a directory

KEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\Policies\System

In the right part of the window, find the file with the nameVerboseStatus. Double click on it and in the window that opens enter the value1 .

If the file VerboseStatus does not appear, you need to create it. To do this, right-click and select Create, and then DWORD value (32 bits).

Give the file a name VerboseStatus and enter the parameter value 1 .

Result

As a result, instead of the usual phrases “Shutting down” or “Starting working”, downloadable and closed services will be sequentially displayed on the monitor screen and windows processes. If your system is delayed for a long time or completely freezes at a certain step, you will definitely know the reason. Reporting the startup and shutdown status does not in itself solve the problem, but it exposes the problem to the technicians you can contact for assistance.

It is likely that this trick can be done on other operating systems. Windows families. If so, please share your experience in the comments.

Computer freezing is a rather annoying problem. This can occur both at the stage of system startup, and in the middle of the process of its operation. Let's see why this can happen and what to do about it?

Why does my Windows 7 computer freeze?

Your computer may freeze for a number of reasons. Among them:

• many tasks in autorun;
• the machine is polluted with dust;
• the presence of malware;
• “Clogged” device memory;
• problems with programs.

Ways to solve problems

Windows 7, 10 freezes on boot in case of problems with the RAM. As a result, a blue screen may appear.

To check the status random access memory, you should use the memtest86 program. If you find errors, try cleaning your computer or go over the contacts with an eraser. In extreme cases, you will have to buy new memory.

Windows 10 freezes while working

Quite a few users are facing this issue. Its main reason is that the software is relatively new. Freeze can occur for a number of reasons:

• marriage of RAM;
• the presence of viruses;
• errors in work hard disk;
• banal overheating;
• crowded autorun;
• lack of hard disk space.

If you notice that the problems started after performing a particular operation, fix it. So, if the "glitches" of the computer appeared after downloading the program, it is recommended to remove it.

The reason that after windows updates 10 the computer freezes, it may be in installing the wrong drivers. You may have installed a driver for a 32-bit system on a 64-core OS. Remove the wrong drivers, perform a system restore.

Reinstalling the system is usually required in the most extreme cases, but it almost 100% solves the problem.

The problem of the operating system hanging when loading is not uncommon. A considerable number of users sometimes observe a tightly frozen Windows logo, and this may be due to a number of reasons: the presence of a software failure or problems with the computer hardware. And in order to correct the situation, you must first determine in which area this problem arose, and why the computer freezes when loading Windows 7.

Overheating and dust

To identify which device is causing the situation in which Windows 7 freezes at boot, you should initially check the computer for overheating. Short-term mechanical check of the side wall system block or a laptop case is most often uninformative: when the PC is turned on, the case parts may simply not have time to heat up. Of course, no one bothers to wait until this happens (if overheating occurs), but this will definitely not add health to the device. Therefore, it is more expedient to resort to programmatic verification.

It is more likely that the operating system will start in safe mode- a special diagnostic environment with limited functionality and disabled secondary devices. To activate it immediately after loading the BIOS, you need to press "F8", which will bring up a menu of additional OS boot options, from which you need to select "Safe Mode" or "Safe Mode with Network Driver Loading".

The next step is to launch a special utility, such as CPUID HWMonitor or SpeedFan. If none of these programs was at hand, then the same network-enabled mode will come in handy: the utilities are absolutely free and can be freely downloaded from manufacturers' websites.

By running the program, you can immediately evaluate the readings of the temperature sensors of devices: for processors and video cards, the normal temperature in the absence of serious loads ranges from 30 to 60 degrees Celsius. Since safe mode is running, which minimally loads system resources, the indicators during normal operation of PC components should be within these values. If the temperature approaches critical values ​​​​(100 ° C), and there is no load on the system (which can be checked through the standard "Task Manager"), then it's time to sound the alarm and begin to understand the causes of overheating, due to which Windows 7 freezes at loading.

Permissible temperature indicators of the motherboard without load - from 30 to 50 degrees. If in idle time the sensor fixes about 70 - the problem is obvious.

Check the temperature of the RAM and power supply programmatically will not work, since thermal sensors are not installed on these devices. The easiest way is to check the air jet at the outlet of the PSU (if it is clogged with dust, it will blow like from an oven), and a tactile memory check (with caution: if the RAM overheats, touching the modules is fraught with burns).

The lack of cooling can be caused by banal dust blockages or drying out of the heat conductor. In cases with dust, with proper dexterity, it is quite possible for an ordinary user to clean up the inside of a PC, but changing thermal paste or conductor plates requires certain skills. In any case, after eliminating the causes of overheating, the system will boot up normally again.

Component problems

If the temperature test did not reveal any problems, everything is fine with the order inside the device, but Windows 7 hangs on the logo when loading anyway, you can resort to testing the hardware. In such cases, attention is usually paid to HDD and working memory.

Hard disk check

A problem with the mechanics of a hard drive is most often identified in the early stages of its occurrence, since it is difficult not to pay attention to extraneous sounds that have appeared, such as clicks or uneven buzz. In this case, as a rule, not only hangs Windows boot 7 when starting the computer, but there are also micro-freezes and freezes during operation. The problem may lie in the loose contact of the power connectors (especially with the SATA interface). A simple replacement of the four-wire power cable will help. But if this did not help, then it is time to think about acquiring a new storage medium and maximize quick creation backup data.

Logical errors in the operation of the HDD are detected and corrected using special utilities, such as the free but effective Victoria or HDDScan. These programs are able not only to detect and fix software failures of the disk, but also to localize and mark bad sectors, isolating the problem areas of the physical structure of the disk. Logical errors are correctable, physical damage is gone, so the first ones that occur on a BadBlock disk are a signal to the user that the disk is used as storage important information no longer worth using.

Checking RAM

If you suspect that Windows 7 is hanging at boot due to a malfunction of the RAM, you can try to remove the memory modules from the slots, blow them out with a syringe, and then insert them back. If there are more than one modules, start the PC, alternating them and observing the behavior of the computer. As practice shows, these manipulations are quite enough. However, if the problem still persists, you should use either standard means OS (Verifier Windows memory 7 is called by the mdsched command), or one of the third-party utilities (MemTest86+). Experts recommend using MemTest, since the utility performs a more thorough analysis of RAM.

It should be borne in mind that the presence of errors in the RAM test does not always mean a malfunction of the memory modules themselves, the problem may also be hidden in the motherboard. One way or another, a full answer can only be obtained at the service center.

Software failures

PC hardware errors are not the only reason why Windows 7 freezes when loading the desktop. In the software environment, there can also be a lot of them. Moreover, a significant part arises through the fault of the users themselves.

Crowded autoload

The problem that is observed most often occurs among inexperienced users who do not understand the basics of installing software on a computer. This is especially true for fans of various cloud services, whose online installers often litter the system with additional software, besides placing it at startup. At the same time, the possibility of canceling the installation of these components by the user is simply ignored or not noticed. The solution is to check autoload and clean it if necessary. This can be done using the Msconfig system utility by calling it with a similar command from the Run menu. The "Startup" tab contains a list of all applications that start at OS startup. Disabling autorun is done by unchecking the line.

viral infection

There are enough ways for digital infection to enter the system: dubious sites, downloading and running unverified executable files, using infected removable media etc. The behavior of viral products may vary, but Negative influence to boot the OS is quite common. Solution - full system scan antivirus program. At the same time, the degree of infection is an important point: in some cases, it may be necessary to launch an anti-virus product with bootable media.

Incorrect driver installation

In this case, Windows 7 freezes at boot, mainly due to a video adapter and motherboard driver error, especially during an update. The problem is solved by manually removing the driver through the Device Manager or by restoring Windows from checkpoint(if system restore is enabled).

Windows Component Update

This is most often caused by a power failure during the update process, although program reasons should not be excluded. If Windows 7 freezes when loading after the update, but the download and installation process went as normal, it is recommended to just wait for a start: it is when the computer starts that the OS configures the installed components. As a rule, everything is limited to a relatively long wait.

But if there is no result, and after a long Windows time still showing the start screen, you will have to boot into safe mode and call the command line (Click "Run" and then enter cmd). Next, you need to enter the sfc /scannow command. She is responsible for scanning and restoring the integrity system files OS. In cases of update problems, this is usually sufficient.

Many PC users often encounter a problem when windows 7 freezes on the logo when loading, i.e. the download normally goes to a certain place, after which the operating system (OS) falls into a “stupor” and is brought to “feelings” only after pressing the Reset button .

There are many reasons that lead to this phenomenon, among which we can distinguish 5 of the most common. Let's consider them in more detail.

Possible causes and solutions

• virus programs are the main cause of fatal changes in the operating system;

It is necessary to use modern virus scanners, which will help identify and remove malware and spyware from your PC. If the antivirus did not help, then manually end suspicious processes in the registry and startup, then find and delete all suspicious files from the hard drive.

• Stopping the OS startup can occur when the processor and chipset overheat;

A broken cooler, old thermal paste, a radiator clogged with dust can stop a PC from working in a matter of minutes. When the system boots, you need to use one of the many utilities to check temperature regime CPU, video card, chipset.

If the cause is overheating, and the cooling is functioning, but clogged with dust, then it is necessary to clean the PC using compressed air or a vacuum cleaner.

• RAM problems also often lead to unplanned shutdowns when starting Windows 7;

Among the problems of the RAM, the most common are overheating and a defect due to damage to the memory module. Unfortunately, the last type of problem can only be identified through testing.

Recommendation of experts: in case of overheating, use special heat sinks that significantly reduce the risk of RAM failure. If this does not help, replace the device. A factory defect in a RAM module can resurface even after prolonged use of the memory.

• falling into a "stupor" of the PC when starting the "OS" often occurs due to mechanical, electronic, logical or software and hardware failures in the hard drive;

You can detect problems with the hard drive by testing by running the utility in Widows 7 or using third-party software. Extraneous sounds often become harbingers of screw problems. When incomprehensible noise and clicks appear in the “hard”, you need to make a backup copy of its contents and be ready to purchase a new device.

• sometimes, the reason for the "braking" of the computer during the initialization of devices is incorrect settings or an outdated BIOS version;

Most often, this happens after installation on the old system board new components. The BIOS may simply not have information about them. The solution in this case is quite simple: initially restore the factory settings or update the BIOS.

Sometimes you can solve the problem of PC freezing at startup by rolling back to the checkpoint that the system creates.

For this you need to have boot disk and follow a few simple steps:

• restart the PC and go into the BIOS. Depending on the manufacturer, the entry keys may be different, most often it is Del; F2; Esc. In order to accurately determine the entry key, you need to refer to the documents that come with the motherboard;
• change the download priority. To do this, go to the BOOT section, after which you need to go to the Boot Device Priority menu item;
• select the item 1st Boot Device and confirm by pressing Enter. In the Option window that appears, highlight the drive and press Enter. After this procedure, the PC will start from this device;
• exit this menu, then press Esc, then Exit, after Enter, and then confirm saving the settings with the Enter key;
• insert a disk with an “OS” or a boot disk into the CDROM and reboot;

Tweaking the Registry to Identify a Hanging Issue

In order to definitely identify which process is causing the OS to stop starting, you should make a small adjustment to the registry entries.

You can do this by booting with command line support by entering the command: regedit.exe.

• in the left part of the window that opens, select the KEY_LOCAL_MACHINE folder, after that, open SOFTWARE, in this directory find and open Microsoft, then Windows;

In this directory, you need to find and open CurrentVersion, then Policies and finally System;

• having opened the System directory, pay attention to the right side of the window;

In it you need to find the Verbose Status. Open it and in the tab that opens, set the value to 1; (Default is 0)

Important! You should be aware that the desired file may not be in the registry. In this case, it must be created. Click on free space on the right side of the window, select the New menu item, and after that DWORD (32-bit) Value. Name the created file VerboseStatus with value 1.

• after that, the registry can be closed and rebooted;

As a result, when you start the OS, you will see the loaded services and system processes. On which it will stop - and is the cause of all troubles.

Working with BIOS settings

The shutdown procedure often helps to get rid of the "machine" freezing at boot: often - but not always. Sometimes BIOS settings play a decisive role, changes in which almost always lead to a PC freezing.

What you should pay attention to:

Panacea - factory reset.

Disable devices

Let's assume that the report reports that the system went into hibernation while loading the CLASSPNP.SYS driver.

In order to find out which device this driver is responsible for, you can try disabling PC components in the BIOS one by one:

If you find a component that causes Windows 7 to hang on the logo when loading, you can install a discrete device in an expansion slot on the motherboard.

Important! In the event of a device replacement, the PC may not load the OS, displaying error information on the monitor screen. To fix this, go back to the I / O system, go to the Halt On tab, and select No Errors. On the Halt On Errors tab, you need to set the value to None. Now the PC will boot even with an error.

Reset to factory settings

You can reset the parameters to "factory" in several ways, the most common of which are:

• reset directly from BIOS;
• by removing the battery from the system board;

In the first case, you should go into the BIOS and select the Load Fail-Safe Defaults option. After that, answer yes to the question about resetting the parameters and save the changes. After an automatic reboot, the changes will take effect.

Method two, the easiest:

• de-energize the PC;
• remove the cover from the computer system unit;
• remove the battery from the motherboard;
• after 15-30 seconds, put the battery back in place;

Thus, the parameters will be set by default, i.e. factory.

Installing a new BIOS version

In some cases, the BIOS may not be able to properly support all computer components due to outdated version firmware.

This leads to their incorrect operation and braking of Windows 7 at startup:

Important! During the update procedure, do not turn off the power of the PC. This may damage the motherboard.

The methods described by us allow you to effectively solve the problem of a computer freezing at startup. If you think that the above methods do not suit you, or the PC has not been restored, then by all means contact service center where professionals will take care of the problem.

Your computer freezes after startup and you could not continue to do anything with it in the future! Sounds like a familiar issue? Then I believe you have full right know the reasons too, presented here. When working on computers, there is a high chance that your system may freeze out of the blue. If your computer often freezes, it's time to find out the reasons for such failures of your system.

Reasons why the computer freezes at startup

There are many reasons for a computer to freeze at startup. Below are a few reasons that can cause the adverse effects of your system freezing more frequently.

Defective hardware (electrostatic discharge and loose connections between hardware and motherboard computer).
Malfunctioning software (RAM codes; software infected with adbots, viruses and spyware).
The operating system is listening (damage Windows Registry operating system).
Infected drivers (incorrect driver installation, small programs that allow hardware and software to work in sync mode).

In all the problems listed above - this is the root cause, and this is the answer to your question about why the computer freezes, almost all computers today are assembled from hardware components that are manufactured by different companies, which can lead to hardware malfunctions of the system. If your software is corrupted by malware over the Internet, the computer freezing at startup is a warning sign indicating that your operating system may be at risk. This is because viruses and spyware usually copy their code and store it in hidden places on your system, thereby using more memory. Ultimately, this slows down your system. However, if the registry of the operating system is corrupted, then a symptom such as a computer freezing at startup will mean a warning to reformat your system.

Computer freezes shortly after startup - troubleshooting

Sometimes, it may happen that you cannot log into your system when the system boots up, the computer freezes randomly, and no matter how many times you press the keys and bang the mouse, the system remains frozen. In that case, I would suggest you try the following:

Reboot your system and set your system to clean boot.
Click Start, type msconfig in the Start menu search box, and then press Enter.
The system may ask the user for confirmation, sometimes asking for an administrator password. Enter your password and click continue.
Now, on the General tab, click on the Selective Startup button and on the General tab, under Selective Startup, uncheck Load Startup Items.
Select the tab, check the box - Do not display Microsoft services. Then click on the disable all button.
Click OK. And after the hint system disappears, click on reload.
If the system starts, identify the number for the Microsoft services that are causing the problem if your system is running Windows control 7.

After starting the computer, check the registry. Here are a few steps to check it out.

Click Start.
In the search box to launch the menu, type regedit. Press the Enter Button.
Now locate the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem

Once the partition is found, set the NtfsDisable8dot3NameCreation icon to 1 to remove all duplicate or multiple DOS versions of the names.

Computer freezes after startup but runs in safe mode - troubleshooting

Most people complain about computer freezes in Windows 7 and they have also noticed that it prompts the system to start in safe mode after a reboot. Now, before understanding whether this is safe mode and whether or not to run it, it is important to understand what safe mode is. Safe Mode is a special way to boot Windows when the system doesn't want to start normally. In safe mode, not all features are enabled. Most device drivers are not loaded (such as printer and scanner). The batch files autoexec.bat and config.sys do not run. Uses standard VGA graphics mode, not graphics drivers devices. In this mode, the system checks msdos.sys for information to find the required files. So now the question arises, what to do after the system boots into safe mode? To check the root cause of what caused Windows to boot incompletely, your first course of action should be.

Click on Start, and click the button on the control panel. IN Lately if you have added any device driver, try uninstalling it and then try to reboot. If the system boots normally, it means that the device had some kind of conflict with the drivers. Get more detailed information to install games or new apps and try uninstalling them if you have any doubts about installing them. However, if there are no problems with the hardware or software, then this indicates the presence of a registry corruption issue that can only be resolved by obtaining new installation copies of Windows.

When you encounter such a problem, don't jump to the conclusion that your system needs to be reformatted. Check everything possible reasons and try to figure out the reason why your computer freezes after startup. And yes, one more important thing, always keep your data on a device backup such as a CD or flash drive. This will save your work at least!
