Black screen. Black screen when you turn on the computer? What to do? Restore system files

The appearance of the black screen when loading the operating system can have a user at least to cause bewilderment. What causes a malfunction when it appears when you turn on the computer black screen? In this case, the launch seems to be, but the image itself does not appear (there is nothing shown on the monitor). In some cases, there is also no cursor, there is no signal and need to take measures to promptly correct the situation.

Then how to remove the black screen on the working computer when the image does not appear on it? First of all, it is necessary to understand what exactly the cause of a malfunction is. The reasons for such a breakdown include technically and software, but in 50% of cases the user itself is to blame because of its inattention, and sometimes simple not knowledge.

Example from life. The motherboard was bought with a built-in video card. To increase productivity, an additional outer video card was purchased. When assembling the PC, everything was connected correctly and worked fine. Next, after cleaning or transferring the system unit, the wires were disabled and is not re-connected correctly. The wire from the monitor instead of an external video card turned out to be connected to the built-in (VGA or DVI connectors are the same on all devices). Naturally, PC was configured to work with an external video card and with the built-in it just do not start. Inattention or ignorance? Make conclusions yourself.

Technical reasons why the monitor is not included, the cursor is not visible and there are no standard laboratory inscriptions, are the following:

PC is translated into mode for working with an external monitor (in this case, the absence of a signal is relevant for laptops).
The fault of the loop (also the problem is actual only for laptops).
Fault video card.
The cable connection is not to that connector.
The cable that connects the system unit and the monitor - again the black screen appears after loading.
Disable power from the monitor, so it does not start, nothing on the screen appears, even the cursor.
Malfunction of the monitor.

The software faults that lead to what is not turned on when a monitor is started, a black screen appears, refer to:

The presence of a viral malware, which prevents the computer to carry out work. It is because of her a black screen on the monitor is shown.
Unsuitable screen resolution.
On the computer's video card, the wrong update rate.
The incorrect operation of the operating system or drivers.

Technical Plan Solutions

To solve the problems of the technical plan, how to remove the black screen, will reasonably use the following action plan:

You need to make sure that the personal computer is turned on. For this, the presence of working lights, the sound of the working cooler is checked. The cursor does not appear.
It is checked if connections cables with a system unit are connected, power cables with a monitor, and the button is enabled on the monitor.
If a black screen occurs when the computer is turned on, then check the connection of the cable to the jack. If necessary, you can reconnect cable.
If the computer uses a built-in and external video card, then you need to check how the monitor is connected to which of these devices. You may need to switch the cord to another connector.

In laptops, it is almost always an output to connect an external monitor. If when the laptop starts, the sound of the coolers is heard, which is accompanied by a black screen on a computer, it is likely that it is easy to operate with external monitors. On the keyboard, find the function keys to control the operation of the external monitor and try to enable the internal display.

Using the F7 key, the inner screen turns on / off, and the F8 button controls the output combination to the internal / external laptop monitor. They need to be pressed simultaneously with the function key, which is usually indicated by Fn.

Different modes of operation are switched by sequentially pressing the following key combination: Fn and F8. Considering the question of how to remove the black screen, you can try this method if the internal laptop monitor was accidentally disabled.

If you are sure that the black screen with the cursor is caused by the technical problems, and the actions described above did not help you resolve the issue, the signal is still no, then you should contact the company to repair or in the service center. In this case, you can hardly remove the malfunction yourself.

Solving the problems of software failure

If you encountered a black screen after turning on the computer because of a malicious program or software failure, it is recommended to perform such steps:

Try downloading the OPERATION in safe mode. If you managed this, you need to continue to perform actions below. If not, the only option will be the operation of the operating system using external media.
When the operating system is loaded in safe mode, it is necessary to check the update frequency settings and screen resolution. If the computer monitor has not turned on before, they must be replaced with the right.
The video card drivers are then updated. Although the safe mode is used, but this should be done using the Device Manager.
If the monitor has long turned on on the computer, then you need to launch the anti-virus program and carefully scan the PC to infect malicious software. Ruthlessly destroy all the files that provide a threat.
After performing all items, the computer should be reloaded.

When the monitor turns on, it turns off immediately or arises a black screen after switching to a new monitor, you need to do the following:

The old monitor connects to the computer.
Installs the minimum screen resolution and the update frequency of 60 Hz. This is done in a special video card driver utility or in the screen properties.
The computer connects to a new monitor. Now you need to adjust the screen resolution and the frequency for a new display.

There are cases when, with the fulfillment of computer, the above-described actions do not help solve the question of what to do if a computer with a black screen. In this embodiment, you can contact the specialists. Some malicious programs are detected only manually, while antivirusers will be useless.

Unusual causes

What to do if the black screen is caused by non-technical and non-software? The black screen may appear due to the banal inattention of users who sometimes reach the absurd. Before you start finding complex causes of the problem, it is worth checking your attentiveness:

Could you specifically or by chance to minimize the brightness of the monitor? Then you can not say that the monitor turned on for 2 seconds and goes out, but the image itself is absent.
Will the metal parts of the PC do not "short? Static electricity can get on the computer enclosures. The device will start to turn off suddenly for the user, even when loading. This problem often causes touch to the body of elements conductive, or a large accumulation of dust inside the system.
It is worth listening to the sound of the cooler. Does the fan work, are there unusual sounds? Often due to the cooling system malfunction, the PC is sudden. To avoid such a problem, the computer must be kept clean. It should not be leaning the cooler to the cabinets, walls and not to be located near the batteries.

The problem of the black screen appears when the computer is turned on, is solved by correcting a specific error. If you check the case on the passage of static voltage, add brightness or replace the cooler, the problem is able to decide.

In any embodiment, the appearance of the black screen should not lead the user to a panic. You can only exacerbate the situation in the breaking of fright or beware. It is impossible to knock on the system unit and monitor, this will not solve the problem, and it may generally bring the computer completely in order. It is not recommended to disassemble the Socketer yourself and switch the wires in it if you have no experience in its repair, and you do not know the principle of computer operation.

Hello everyone! If you see a black screen when you turn on the computer, then this is the first sign that some problems have happened in his work, which do not allow the Windows operating system to function normally. The reasons for such a phenomenon can be somewhat, list them:

Incorrect shutdown of Windows;
Damage to the interface monitor connection cable or no contact;
Non-loading desktop;
There is no Windows license;
The components of the system unit do not work;
Problems with software, lack of drivers;

As you can see, the reasons when the black screen appears when the computer is turned on, quite a lot, so we will analyze each of them separately and try to eliminate the problems yourself.

Problems when downloading windows

Probably the most common reason for the appearance of a black screen is a failure in the operating system. Very often it occurs when the system is incorrectly completed or damage the boot area.

In most cases, this problem occurs when users suddenly disconnect electricity and the computer turns out to be de-energized at the most inopportune moment.

With this outcome of the events, the user will see a black screen when the computer is turned on with the system load options.

Here, most often, it is enough to choose the option "Normal Windows Load" and wait when the system starts.

If the system does not give you a window with download options, then you need to do the following:

After you have turned on the computer, you must press the "F8" key, the "Additional Download Options" window must appear;
In this window, you can select three "Safe Mode" options. Using it, you can download the system and eliminate the problem that occurred after an unexpected PC shutdown, incorrect installation of software or viruses;
If you are sure that everything is fine with the computer, then choose "Ordinary Download"

Cable or monitor problems.

Sometimes there are cases when the monitor connection cable is in order to the system block. In this case, it is necessary to examine it for damage. Especially close attention must be paid to the connectors. A fairly common cause in the curved blows of contacts at VGA cables.

To exclude a defective cable, it will be enough to take the substitution and connect.

If everything is fine with the cable, then check the monitor. To begin with, we pay attention to the power indicator (light bulb on the monitor panel). If the indicator is on, the power on the monitor is fed, if not, we look at the power wires. Maybe they are not connected to the network or departed any contact.

If you can connect another monitor, you will certainly use it.

Windows is not loaded.

Another fairly frequent reason for which the user sees the black screen when the computer is turned on, this is not a loading desktop. The problem occurs after the treatment of a computer from viruses. At the same time, the system seems to be loaded, but the desktop remains empty: neither labels, nor folders, no taskbar. If you have a similar situation, we do the following:

HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / WindowsNT / Currentversion / WinLogon

The black screen when you turn on the computer - Windows is not licensed.

For most users, the emergence of a black screen on the desktop is surprising, after updating the operating system. This happens to users of a pirated, hacked version of Windows. At the same time in the lower right corner, near the clock, you will see the inscription: "Your system is not genuine, purchase a license."

If you encountered this problem, then you have two solutions:

Reinstall the system, and after reinstalling, disable the installation of all updates, but then you risk the fact that your computer can be infected with a virus, for example, such as;
Purchase a license to your product and sleep peacefully. After all, the computer will receive all the necessary patchwork and work more stable.

Unfortunately, another exit from this situation is not given.

Faulty components of the system unit.

Note! All actions, produce when the computer is turned off. To avoid lesion to the current.

If the above tips did not help eliminate a malfunction, then most likely there is a problem with one of the components of the system unit.

To begin with, you should open the system cover and inspect the computer components, it is possible to clean them from dust and dirt.

Also, inspect the motherboard on the subject of the swelling capacitors, perhaps the reason for all the troubles in them. Then most likely, it will be necessary to replace the node, namely the motherboard or the rope of faulty items.

Remove the video card from the system unit and clean all contacts. Perhaps over time, oxidation or dust hit.

RAM can also be caused by a black screen and system failure. If the memory modules are several, then remove everything and try to connect one by one and test the launch of the computer. With a good start of the system, we conclude that some kind of memory bar does not work correctly, and change it to another.

Also be sure to clean the contacts of all memory modules, it is possible that the reason is quite banal, there is no contact between the port of the motherboard and the RAM module.

Problems with a video card or driver.

In my practice, there were often cases when a black screen appeared when the computer is turned on due to a faulty video card. Since many modern PCs are equipped with a discrete and built-in graphic adapter, you can simply connect the monitor to the embedded video adapter and check if the image appears on the screen.

A fairly common cause of failure of discrete video adapters is overheating. By the way, if you do not know which video adapter you have installed, then read the article -.

Less frequently, the image on the screen refuses to appear due to incorrectly installed drivers. To exclude this problem, download the latest version of the driver for your video card from the official site and install. Perhaps the problem will be solved by itself.

Let's summarize.

Today, we reviewed the solution to the problem where the black screen appears when the computer is turned on. I hope the tips described in this article will help you to identify the cause of the fault and eliminate it. The main thing is to act, not in a hurry and relate to the case meaningfully.

The black screen appears when starting the operating system, is called one of the most difficult errors of its operation. At the time when the user sees problems with the loading system, the first thought arises of its reinstalling. But this is not the only measure that can be taken when Windows 7 is not loaded. The black screen can be removed in other ways.

Causes of windows 7 black screen appearance

First of all, it is necessary to understand what reason this failure arose. Then you can fight it more efficiently. There may be several reasons:

failure of the video card drivers - in this case, it will not be displayed on the black screen: neither symbols, nor cursor;
troubleshooting after software updates or system itself;
the presence of files involved in the loading of the system running incorrectly;
damage to viruses;
defects in computer equipment.

The first thing to check when you do not start the computer - peripheral devices are connected to it: flash drives, smartphones and others. It is best to disable them and restart the computer - in some cases it will help get rid of the black screen.

Rollback using system recovery points

If you are regularly when it worked stable, then the black screen when booting W Indows 7 can be removed with their help. To do this, you need to follow the instructions:

Restart the computer and until the OS boot, press the F button 8. The screen must appear with the launch options.
On this screen, use the arrow keys to set the cursor on the "Last Successful Configuration" option.
Press ENTER. If after you appears a regular operating system boot screen, then the problem is solved.

This method will help if the failure occurred after a viral attack or due to the system update. Select the system image to download by the date of its creation.

Debug mode

The creators of operating systems included special tools to restore the launch in the shell. If you do not start Windows 7, the black screen can be removed according to the instructions:

At the time of downloading the computer, press F 8. Select the "Troubleshooting" option from the list.
After clicking on ENTER, start the recovery wizard. Working with him is simply and intuitive. First, select "Start Recovery".
After that, the system automatically scans its files and restores them using records in memory.

After restoring the computer will reboot, and you can again see your desktop. Debug mode helps well if the computer stopped run after power failure.

Restoring the system with a secure mode

When you click on the F 8 key, you can select another download option: "Safe Mode with Command Line Support". This option also helps to remove the black screen when you start Windows 7. You need to work with this tool:

Press F 8 while running the computer, after the starting screen appears with technical information. Select the download option in secure mode with command line support.
The system will start the command line window. You need to enter the Explorer.exe command and press ENTER.
Thanks to this team, the conductor is activated. You will see the usual design of the operating system, but rejoice early. You need to go to standard programs in the Start menu. Then deploy the "service" directory and click on the "Restore System" line.
You will appear in front of the wizard window reanimizing the system. Click the "Next" button and select the Point to Recovery.
Now you will only have to confirm your choice button "Finish". In the pop-up window, click "Yes."

The computer will start the rollback operation, in the process of which it will be rebooted. After that, the black screen of Windows 7 will disappear.

Comprehensive Windows 7 Computer Restore

If you do not have a previously created recovery point or previous options did not come up, then you need to follow other instructions. It is suitable even if the system files are too damaged, and the operating shell is not loaded even in safe mode. If you appear on your Windows 7 black screen and no dots for recovery, do so:

During system boot, press F 8, select "Troubleshooting" from the list. Press ENTER to download the utility.
You will appear a list of available tools from which you need to choose the option "".
The command line window will appear on the screen. It needs to enter the REGEDIT command to download the registry editor interface. After entering Enter.
The feature of the started editor is that the entries in it refer to the recovery environment. Therefore, you first need to select HKEY_LOCAL_MACHINE. Then click the File button and select the "Load bush" command.
In the address string, enter C: \\ Windows \\ System32 \\ Config or sequentially go to Windows folders, System 32, Config. In the folder that opens, locate the System file and click on the Open button.

After this command there will be a restart of the system, after which it starts in normal mode.

But on this work with the restoration of the system is not completed. It is worth downloading utility

There is a very common domain among the owners of the PC - you turn on the computer and see when loading a black screen.

What are the reasons for this failure and what to do in the current situation is the main topic of this article.

Problems arising when loading the system

The problem has a wide range of factors provoking it.

In addition, the black screen can also be displayed in different ways, for example, with or without cursor.

Let us consider in more detail the main causes of breakage:

Internal error in the operation of the operating system, due to which it fails to adequately interact with the graphics environment;
Crash driver for the video card (incompatibility with the installed version of windows);
Breakdown internal computer drive;
Critical violation of Windows OCs, preventing adequately to produce its download even in Safe mode;
Other conflicts of the PC hardware department;
The inability of the operating system is out of sleep mode.

Windows load in safe mode

Initially, you should try to make a secure system load.

Disconnect external devices from the computer, as well as flash carriers, which could also be the cause of the conflict.

Turn off the computer to stop all the processes that cause a black screen.

Then re-launch it, at the very beginning of which you must press the F8 button on the keyboard (Delete, Shift + F8 - depending on the installed operating system).

In the Advanced Download options window, select the desired option.

In this case, safe mode.

If the computer will start in this mode without any problems, you can assume the system settings failed.

Further refers to the emergence of an error after the next update in the OS registry, and wrong operation drivers.

Here the activation of the operating system is the first step towards correcting the problem.

Many use an unlicensed copy of the Operations, the next update of which sometimes ends with the appearance of a black screen.

It arises due to the impossibility of passing a "pirated copy" of identification on the website of Microsoft Corporation.

If it is so after downloading in a safe mode, you will see a warning on the screen to use the unofficial version to be licensed.

To get rid of the problem - activate your copy of the operating system.

Equipment malfunctions

Monitor and system unit

The cause of the black screen may be problems with equipment.

For example, due to poor monitor contact with the system unit, when the signal from the video card does not receive.

Lack of normal monitor network cable contact with socket

In this case, check the quality of all connections, and the availability of outdoor damage to the screen, due to which the image may be missing.

If such a problem arose on a laptop, then the reason is practically not always associated with the display, because in order to damage it, it should be a strong mechanical impact, for example, a drop or blow.

At the same time, the deformation of the monitor will be visible to the naked eye: color stripes, plots with bits with pixels, scratches, and the like will be traced.

On the computer, a black screen when entering the system can cause a breakdown of one of the components of the system unit, so it will be necessary to study in detail.

First of all, attention should be paid to the video card, namely the reliability and density of its attachment in the motherboard slot, as well as the stability of the supplied voltage and cooling (if it is not passive).

Verification of video card drivers

Check the status of video card drivers that can conflict with the system.

To do this, it is necessary to start the operating system in safe mode again by activating the video mode of the screen with a low screen resolution in its menu.

After the login is implemented - go to the control panel.

To do this - right-click on the menu "Start" and choose from the list item that appears "Device Manager" .

Choose there in the section "Video adapters" The installed video card and go to the properties window.

On the tab "Driver" Click on the button Delete.

Then restart the computer and install the factory drivers that are supplied with the video card.

You can go to the site of its manufacturer and download their latest version there.

If you are unknown, what drivers should search - call the tab « Perform» Using a key combination Win + R..

In the opening field, enter

and click on the button " OK».

In this case, the Diaptx Diagnostic Tools window appears in which the name of the available video card will be displayed.

Using the information received, download the necessary of them is simple enough.

Elimination of a possible conflict of software components

A characteristic feature of this option is, after several reboot attempts, the computer still manages to run.

The "treatment" technique will be approximately similar to the previous case, the only difference here is that you need to select the item in the Windows configuration section. "Enable Safe Mode" .

Then in the upper line we sort the installed software by the download date.

Now, looking at the list of installed software, you need to find the perpetrator of the problem and remove it.

It will be best to do through third-party programs, such as CCleaner, since with him you get rid of all residual elements after removal.

To get rid of a suspicious program, you need to go to the section "Service - Delete Programs" And choose the option you need.

Motherboard drivers

The black screen is sometimes due to the conflict of maternal drivers and systems.

Repeat the previously described actions to delete and install in their place a working program.

Be careful when working with drivers, otherwise it is not possible to completely reinstall the operating system.

To secure yourself from this - set the checkpoint to which, if necessary, you can roll back the system.

In the case when, after replacing the drivers, the black screen periodically continues to resemble yourself - continue the search for the cause.

Try to delete all programs that can cause a system conflict, as well as test the computer for various malicors.

Run the system again in safe mode and open the control panel by clicking the right button on the icon. Start».

From the list of the list, select " Programs and components"And click on it.

Carefully analyze which programs have been installed lately and can cause a conflict situation.

Delete them using Windows standard features or third-party program.

One of the best is currently being CCleaner.

The program is understandable and quite effective, which allows you to delete all the accumulated file trash.

All that will be required of you - Install checkmarks in the section « Cleaning» opposite the right points.

After analyzing the program, click the button « Cleaning» And expect to complete it.

Going to the tab « Service» You are free to choose programs to be deleted.

Select the desired and click on the button. « Uninstallation» .

Restoration of system registry

The periodic appearance of the black screen can also be also due to damage by some data of the systemic register of malicious programs.

To get rid of it - you should restore it to a fully working condition.

For this discover « Task Manager» Using a key combination Ctrl + SHIFT + ESC.

In the window that appears, go to the Application tab. Here you will need to create a new task by clicking on the button of the same name and entering the value in a special field.

In Windows 10, this is done easier. Right-click on the menu « Start» and in the list that appears choose the item « Perform» .

In the input field prescribe

Regedit.

and click on the button OK.

Windows registry

A system registry editor opens.

It needs to find a string named " Shell."And click on it twice.

When a string parameter change window appears, delete all records of the parameter " Shell."I enter the vacation field

Explorer.exe.

After that click on the button OKBy keeping the changes done.

The final step is to restart the computer, allowing the settings to enter into force and debug the registry.

With the following actions, the registry will be restored, and the black screen will no longer appear.

System restoration by third-party programs

Delerate work explorer.exe. You can not only manually, but also with the help of a small AVZ utility.

It should be pre-downloaded and install on your computer.

The main window of this anti-virus utility contains several menu items, including the following:

File;
Service;
Avzguard;
AVZPM;
Reference.

Choose item « File» , and from the list appeared - » .

You will then find the Restore function settings window in which you want to activate the 8th and 16th strings (restoring the conductor settings and restore the Explorer launch key).

Having installed the checkboxes opposite them - it will stay on the button Perform marked operations And wait for the end of the process. Upon its completion, be sure to overload the computer.

Bus load

It often happens that the program located in the autoload, or a very large number of them, can cause the periodic appearance of the black screen.

Two the number of Windows running programs to a minimum and, if it does not remove the existing error, then at least speed up the launch of the operating system itself.

Perform this condition easily with the command

Msconfig

which should be prescribed in the menu window "Run" .

Clicking on the OK button you will get into the window "Windows Task Manager" in which go to the tab.

This tab displays all programs involved in the start-up software.

Select all the unnecessary programs and click on the Disable button.

System rollback

With the solution of the black screen problem often will help a simple rollback of Operations to the recovery point.

Although quite often, users turn off this function, considering it almost useless.

But with its help, it is sometimes quite likely to avoid reinstalling Windows, returning to the moment of the most stable operation.

To do this operation is quite possible after loading the secure mode.

Conflict with antivirusman

The inability of launch often provokes an OS conflict with an antivirus program installed.

The latter sometimes mistakenly blocks various system files.

To return the computer to a normal operating condition - it will be necessary to complete some antivirus processes.

Using the combination of buttons with tRL+ SHIFT + ESC Open the task manager window and selecting on the " Processes»Those who are associated with antivirus are completing them.

Remember that this is a temporary measure and with the next start system they will again be launched. To avoid repeat, you should create certain exceptions for anti-virus applications.

If you use the Avast program, it will look like this.

Go to the program settings window and select Active Protection.

Then go to the File System Screen tab and select the section in it. "Settings" .

In the left side of this section, find item "Exceptions" And click on it.

Add the following values \u200b\u200bin the input field - "C: \\ Windows \\ Explorer.exe" and "C: \\ Windows \\ ImmersiveControlPanel \\ SystemSettings.exe". Then click on the OK button.

In order to run the Explorer.exe process, you must use the menu "Run" And enter the name of the process into a special window.

After pressing the OK button, you must overload the computer.

Check and removing viruses

Malicious programs like no other is the perpetrators of the operating system failure.

Therefore, it is necessary to verify not only the section with the system, but also the entire hard disk for their detection.

You can make such an inspection in different ways.

One of them will use the utility 4Mrecoverwhich is present on the boot disk Live.CD 4mrescuekit..

Another option is to check the hard disk on another computer, which has good antivirus protection.

True, this is not very convenient, since you have to remove the cover of the system unit and disconnect the disk itself.

Download

The appearance of the black screen during Windows Reset

In this case, some options are somewhat several:

1. Use another media to install for installation, or write another version of the OS

2. Checking Tom from Windows for the presence of a sectors, because they can violate the installation process.

The flash drive or disk must be checked for other types of damage. For example, mechanical;

3. It is worth trying to select another local disk as systemic.

Fighting viruses and other malware

The fraudulent software is sufficiently developed, and does not harm not only user data, but also important system utilities.

In this case, the cursor also occasionally appears, besides, it is even managed.

The attack of viruses may not be confirmable, but it's still worth trying.

Nowadays, there are a lot of antivirus software components in the market, but it will be best to use the laboratory development. Dr. Web. entitled Cureit..

Using the user, the function of the surface analysis of files on a PC is provided, and more detailed verification, which is what the utility start menu looks like:

If Windows does not load, you need to take a hard disk and connect it to another PC.

Using this program is very simple: you just need "HDD" , as well as the power of checking.

If the above technique did not help - the reason is worth looking for something else.

Download

Creating a restorative flash drive and reinstalling Windows

One of the toughest ways among all the proposed is the complete reinstallation of the available OS to more stable.

Nowadays, the need to record an image on the disk is now easy enough to create a flash drive with the installation program.

Make it just with any specialized program.

Rufus.

One of the best among all available is RUFUS.

The utility despite the scarcity of the external interface is well coped with its destination.

It is very simple to use it: you just need to be in the section "Device" Select the load formatted in NTFS and the image file, and then click "Start" . View of the start page of the application.

To the website

Ultriso.

This program has a slightly larger task arsenal than the previous one.

To create a loading flash drive, it must be reformatted in NTFS.

Running the program, you will see the following window:

and click "Write an image of a hard disk" ;

3. Choose the path to the image;

The worst option when the black screen appears is the failure of the hard disk.

Initially, this reason can be answered if the cursor is visible on the display, as this means that the device functions.

If you observe a completely dark screen, most likely it provoked that the drive simply does not work and, as a result, is not displayed in the system.

Definition of troubles

Immediately it is worth noting that the broken sectors are practically unrealistic to restore.

However, they can be closed to read and write, so they will not interfere with further work. The origin of these damage has two nature:

Logical. It arises due to the incomprehension of the ESS code with the contents of the sector. In essence, these fragments are not broken, but only temporarily unreadable, so they are subject to repair;
Mechanical. Bied sectors of this species are caused from strong blows or strong shakes during operation. These particles finally failed, so they cannot be repaired.

To find and restoration in the Windows operating system there is a built-in check utility - CHKDSK.

This component is launched in two ways:

Through the command line. To do this, call the "Run" menu with the combination of Win + R and enter CMD into it. In the window that opens, enter the following values: CHKDSK C: / where C is the letter denotation of the local disk checked;
Through the properties of the section in the tab "A computer" .

Black screen when booting Windows 10

Some users of Windows 10 complain that in the process of loading instead of the usual screensaver, a black screen is displayed. Most often, this problem pursues those who installed Windows 10 by updating the older version of the OS.

Sometimes users when loading the system are encountered with such an unpleasant problem as the appearance of a black screen, which displays only the mouse cursor. Thus, it is simply impossible to work with a PC. Consider what are the most effective ways to eliminate this problem in Windows 7.

Most often, the black screen appears after the Windows welcome window has been opened. In the overwhelming majority of cases, this problem is caused by the incorrectly installed Windows update when some failure happened during installation. This entails the impossibility of running the Explorer.exe system application ( "WINDER WINDOVS"), which is responsible for displaying the graphics shell of the OS. Therefore, instead of the picture you see just a black screen. But in some cases, the problem may be caused by other reasons:

Damage to system files;
Viruses;
Conflict with installed applications or drivers;
Hardware faults.

We will explore the options for eliminating the specified problem.

Method 1: OS Restore from under the "Safe Mode"

The first method involves the use of "Command Line"launched by "Safe mode"To activate the Explorer.exe application, with the subsequent rollback of the OS to an efficient state. This method can be used when the device has a recovery point formed before the black-screen problem appears.

First of all, you need to go to "Safe mode". To do this, restart the computer and when it is repeatedly turned on after the audio signal, clamp the button. F8..

The system for selecting the system loading type will be launched. First of all, try activating the last successful configuration by selecting the specified option using the arrow on the keys. ENTER. If the computer starts normally, then consider that your problem is solved.

But in most cases it does not help. Then in the boot type shell, select an option assumed "Safe Mode" with the support "Command Line". Next click ENTER.

The system will be launched, but only the window will open. "Command Line". Drive in it:
After entering click ENTER.

The command entered activates "Conductor" And the graphics shell system will begin displayed. But if you try to reboot, the problem will return, which means that the system rollback should be made to the working state. To activate the tool that is capable of performing this procedure, click "Start" And go to "All programs".

Open the folder "Standard".

Enter the catalog "Service".

In the tab that opens, select "System Restore".

The starting shell of the standard tool to renovation of the OS, where you should click "Further".

The next window starts, where the selection of the point to which the rollback will be performed. We recommend using the latest option, but which was necessarily created before the black screen has appeared. To expand the choice of choices, put a mark in the square "Show others ...". After selecting the name of the optimal point, press "Further".

In the next window you only need to press "Ready".

A dialog box will appear, where the intentions should be confirmed by clicking "Yes".

Rollback will begin. At this time, the PC will be rebooted. After its inclusion, the system must start in standard mode, and the problem with the black screen - disappear.

Method 2: Restore OS files

But there are cases where the files of the OS caused such strong damage that the system is not loaded even in "Safe mode". Also, it is also impossible to exclude such an option that you can simply be on the PC, it is not possible to be the desired recovery point. Then you should make a more complex procedure for computer renovation.

When you start a PC, move to the download type selection window, as demonstrated in the previous method. But this time, from the submitted items, choose "Troubleshooting ..." And press ENTER.

The restoration environment window opens. Choose from the tool list "Command line".

Opened interface "Command Line". In it, enter such an expression:
Be sure to click ENTER.

The shell starts "Registry Editor". But it must be remembered that its sections will not relate to the operating OS, but to the recovery environment. Therefore, it is necessary to additionally connect the registry bush of the Windows 7, which must be corrected. For this B. "Editor" Select section "HKEY_LOCAL_MACHINE".

After that, press "File". In the list that opens, choose "Load a bush ...".

The bush boot window opens. Go to it to the disc on which your operating system is located. Next, go sequentially in directories "Windows", "System32" and "Config". If, for example, your OS is on a C disk, then the full path for the transition should be as follows:
C: \\ Windows \\ System32 \\ Config

In the opened directory, highlight the file called "SYSTEM" and press "Open".

After that, the new partition will be created in the folder "HKEY_LOCAL_MACHINE". Now you need to open it.

In the catalog that opens, highlight the folder "SETUP". On the right side of the window among the elements that appeared, find the parameter "Cmdline" And click on it.

In the window that opens, enter in the value field "Cmd.exe" without quotes, then click Ok.

Now go to the properties window "SETUPTYPE" By clicking on the appropriate item.

In the window that opens, replace the current value on the field "2" without quotes and click Ok.

After that, go back to the window "Registry Editor" By the one, which previously connected, and highlight it.

Press "File" And from the discrete list, choose "Unload bush ...".

A dialog box opens where you want to confirm the solution by clicking "Yes".

Then close the window "Registry Editor" and "Command Line", returning in this way to the main menu of recovery environment. Click here on the button.

After restarting the PC will automatically open "Command line". Drive the team there:
Immediately press ENTER.

The computer check will be launched on the integrity of the file structure. If disorders are detected, the recovery procedure of the corresponding item is automatically activated.
After the recovery is completed, enter the following command:
shutdown / R / T 0

Press ENTER.

The computer will restart and turn on as usual. It is important to take into account that if the system files were damaged, which caused a black screen, then it is quite possible, the root cause of this could be a viral infection of PC. Therefore, immediately after restoring the computer's performance, check it with an anti-virus utility (not a regular antivirus). For example, you can use Dr.Web Cureit.

If none of the specified methods helped, then in this case you can install Windows 7 on top of the working operating system while saving all settings or complete OS reinstalling. If these actions did not give results, there is a high probability that one of the hardware components of the computer failed, for example, a hard disk. In this case, it is necessary to repair or replace the broken device.

The main reason for the appearance of a black screen when loading the system in Windows 7 is an incorrectly installed update. This problem is "treated" by roll back to the previously created point or execution of the file recovery procedure. More radical actions also assume reinstalling the system or replace the elements of the computer hardware.
