Windows 7 has a black screen. How to remove black screen. Software fault diagnosis and recovery

Suddenly, after the next launch of Windows 7, instead of the account login screen or desktop, a black background with a cursor on it may appear. Before we begin solving the problem, let’s delve into its essence, because even a few template instructions for different cases will not always help.

Most often, a black screen and a cursor on it are the result of a virus or malware. Such a program interferes with system settings, making it so that instead of the explorer.exe process it starts itself or completely replaces the above-mentioned file (many remember the Win32 family of viruses that hid files and directories, replaced them with their own “bodies” and even copied their icons for camouflage). After all, he is responsible for the Windows graphical interface: everything that the user sees on the desktop, etc.

One cannot help but recall the Avast antivirus, which tends to block system processes, including explorer.exe, due to excessive activity when starting the PC.

The likelihood of sudden conflicts between video card drivers and the operating system is low, although if they have been recently updated, it increases significantly. And drivers downloaded from nowhere or the use of driver packs only fuel the situation.

More deplorable will be the appearance of bad sectors on the hard drive, especially when they contain fragments of system files, such as explorer.exe. We won’t ignore partially damaged RAM sticks either, but last but not least.

First of all, let's try to start the computer in one of the additional boot options - from the last successful configuration. It is a set of system parameters stored in the registry for the state of drivers, applications and services with which Windows 7 successfully booted for the last time. If, before restarting or shutting down the PC, you installed something, edited the registry or the list of automatically launched applications, this method will clearly help. To implement it we do the following steps.

Let's reboot.

This is done using the Reset key or through the task manager.

In the second case (it is recommended to use it) we call the dispatcher using Ctrl + Alt + Del.
Move the mouse cursor to the “File” main menu item and call the “New task” command.

Execute the command “shutdown /r” to reboot the system.

After the BIOS information appears, click F8 until a menu of additional boot options appears.
Using the cursor keypad, select “Last successful configuration” and press Enter.

Didn't help? This means the source of the trouble is different. Let's move on.

Avast

If the “seven” is protected by a comprehensive antivirus solution from Avast, the application may be the culprit for the fact that the explorer does not load. Removing the antivirus is not an option, but adding the file with which the problem is occurring to the exceptions is necessary.

It’s not relevant for all versions of Avast, but it’s worth a try since similar behavior has been noticed.

Open the Task Manager.
We launch the “AvastUI.exe” process, as in the previous case, by finding the executable file in the folder with the installed antivirus (in Program Files).
In the application menu, click “Security”.
Then go to the “Antivirus” subsection, where we click on the “Behavior Screen” tab.

Click “Browse” or enter the path to the reliable process manually - as shown in the screenshot.

Click “OK” and restart.

Has the blinking cursor appeared on a black background again? Let's move on.

Manually launching Explorer

There are several simple ways to open the program responsible for the graphical interface on the problematic computer.

If we stop at this option, we reboot again, and after completing the hardware self-test procedure, press F8.
In the window, select “Safe Mode with Command Line Support.”

In the CMD text line we write “explorer.exe” and press Enter.

If the process does not start, then the corresponding file is damaged, missing, or cannot be accessed.

Rolling back the system, which we will touch on later, restoring the “seven” from the installation flash drive, fighting viruses and their consequences, or editing registry entries will help here. In the latter case, you will have to get a boot disk with an antivirus program, start from it, selecting the CD/USB with the antivirus program distribution in the BIOS. Depending on it, the method of starting a scan may differ, but the meaning is obvious: we find and remove all viruses at least on the system volume.

If viruses are annoying

Even a laptop that is not currently infected with viruses can crash, displaying a black screen without or with a cursor. By the way, in the first case, the source of the problem may be the video driver. And all because the virus did its own thing, replacing the path to explorer.exe with its own. It is noteworthy that the following method works even without booting into safe mode, and you can also call the Registry Editor through the task manager.

Open the “Run” window through the task manager.

We write “regedit” and press Enter.

Expand the HKLM branch.
Go to the Software section.

We follow the path indicated in the screenshot.

Open the Shell key editing window.

In the “Value” field, set “explorer.exe” and apply the settings.

Let's reboot.

If this does not help, you will have to return to one of the previously saved states of the computer’s operating system.

Rollback

Here we will engage in time travel, provided that the system recovery function is activated.

Through the task manager, open the command execution dialog.
We register rstrui.exe and execute the command.

We indicate the recovery options (it makes sense to select the last created rollback point before the black screen appeared or stop at the recommended one).

Click “Finish”.

We get acquainted with the warning and click “Yes”, but there is no other choice.

Once the process is complete, a notification will appear.

The next time you turn on your PC, the desktop should appear.

When the graphics driver is naughty

Rolling back drivers during a system rollback is extremely rare. It’s good if the graphics driver was installed quite recently, but if it was installed a couple of weeks ago, when resuscitating the “Seven”, many files and applications may suffer. Rolling back the driver will help you get rid of such software, and only if the problem does not occur when you start it in safe mode.

Let's start in safe mode.
Call up the context menu of my computer and click “Properties”.
Click “Device Manager” in the vertical menu on the left.

Open the “Properties” of the video adapter used (there may be several of them in the system: integrated, discrete, built into the central processor).

In the “Driver” tab, click “Roll Back”.

You can also try to remove or update the video adapter driver by downloading it from the official website.

Before this, you should test the RAM sticks using a utility like Victoria 4.47, check the HDD for failed memory cells (chkdsk C: /f) and the integrity of important system resources (command “sfc /scannow”). They are executed via the command line.

Black screen after standby

After resuming from standby mode, a black background may appear instead of the desktop or user selection interface. In such cases, there will be several options, depending on the situation:

rollback or install an older version of the graphics driver if problems began after updating the video card driver, especially when using driver packs or installers downloaded from third-party resources;
alternately switching between four main values of the ACPI Suspend Mode parameter (responsible for software power management of computer components), located in the BIOS section called Power;
reinstalling Windows 7 using the original image, and not the next author’s assembly - it is likely that this caused the problem (removing and disabling some system functions to save disk space and facilitate assembly could have had an effect);
updating drivers for USB controllers, mice and keyboards downloaded from their official support resource;
disabling the PC to go into standby mode;
prohibiting one of the input devices from waking up the PC from standby mode.

Let's look at the last option in more detail. You can restore your PC using a mouse or keyboard. It is possible that one of the devices is blocking the computer from returning to a normally functioning state, and this is easy to determine, at least by the increased activity of the fan blades. In this case, deactivating the option to disable sleep mode for the mouse or keyboard will help.

Do not disable it for both devices at the same time, because you will not be able to exit sleep mode later!

You turn on the computer, watch how Windows 7 slowly starts loading, the desktop is about to appear, but instead of it, your gaze opens... “Malevich’s black square”. No wallpaper, no icons on the desktop - only a cursor in the form of a white arrow, and even then not always. What is the reason for the black screen on boot in Windows 7? How to solve the problem?

Causes of black screens of death when loading Windows 7

Failure to install system updates, drivers and programs - pirated copies of Windows often suffer because of this.
Virus infection - most likely the malicious program tried to replace system files with itself, but for some reason it could not and instead broke the boot.
Damage to files critical for startup or registry sections responsible for this.
Video subsystem problems, including video driver failure.
Other hardware malfunctions (rare).

Damage or deletion of Windows files can occur due to failures in the computer's power supply system (the lights were turned off at the wrong time), user actions (deleted by hand), defects in the surface of the hard drive, and even such exotic reasons as treating the system with one well-known antivirus.

Ways to solve the problem

In the simplest cases, if the cause was a minor glitch, rolling back the system to the last known good configuration will help. The Last Known Good Configuration is the state of Windows recorded at the time of the previous successful startup. To return to this state, launch the advanced boot options menu. To do this, before starting the system, quickly press the F8 key several times.

The following list will appear in front of you:

Select the indicated item from it and press Enter. If the computer starts normally, the problem is solved.

Launch File Explorer manually

It happens that a problem is caused by a failure of the graphical shell, when the file responsible for this is not damaged, but only its launch is disrupted. The task manager will help solve the problem here. Click to call it Ctrl+Alt+Delete or Alt+Ctrl+Shift. In the manager window, go to the "Applications" tab and click the "New task" button.

In the "Create a new task" window, enter "explorer" and click OK. If you see the desktop, the problem was what we expected.

Now we need to correct the launch key for Explorer.exe in the registry - the Windows shell, which creates the user environment we are familiar with - the desktop, folders, etc.

Run the registry editor - Regedit.exe. (it is located in the C:\Windows folder). Open the section. In the right half of the window, find the “Shell” parameter and see what its value is. Normally there should be "Explorer.exe", but you probably have something foreign there.

Right-click "Shell" and select "Edit".

In the "Change string parameter" box, enter a new value. Which one - you already know.

Next, open exactly the same section (Winlogon) in the HKEY_CURRENT_USER branch - settings for the current user are stored here. If there is a "Shell" parameter among them and you did not create it, delete it.

Now all that remains is to find and delete the file that was registered instead of Explorer, since it is obvious malware. You can do this manually or using antivirus programs. The second option is preferable, since this may not be the only malicious file on your machine.

Restoring the system from safe mode

If neither one nor the second method helped, most likely a more serious failure occurred. You can try to deal with it from safe mode. To load it, also press F8 several times before starting Windows, but now select "Safe Mode" from the menu.

Here we have the opportunity to return the state of Windows to a date before the problem. And the System Restore application will help with this. Expand "Start" - "Programs" - "Accessories" - "System Tools". Select "System Restore".

To confirm your selection, click “Finish” and wait until the recovery procedure is completed.

It would not be superfluous to additionally check system files for integrity using the Windows console utility - sfc.exe. To do this, open "Start", enter "cmd" in the search bar and run the command prompt as administrator.

Type “sfc /scannow” into the console window, press Enter and wait until the scan is completed. Sometimes the system asks for a distribution disk to restore files, but more often everything necessary is restored from storage on the hard drive.

To find out whether the video card or video driver was the cause of the failure, run the msconfig system configuration utility (in the same way as you launched cmd through the search bar in Start).

Reboot to normal mode. If Windows can start, the problem is in the video subsystem. First, update the video card driver, check if the graphics processor is overheating and, if possible, test the computer with another, known working video card.

Using the recovery environment

If the previous option did not help or you also see a black screen in safe mode, there is still a chance to fix the problem through the recovery environment. It also has the ability to run a system rollback and check file integrity, but there are also special options: boot repair and restoring Windows from a saved image.

To get into the recovery environment, select "Troubleshoot your computer" from the F8 menu (the key you pressed before starting boot).

Follow the instructions until you reach the recovery options window. Select the top item - "Startup Recovery". The program will automatically check the data responsible for this - boot files and registry sections, and if there is a violation, it will restore it.

The second item from the top is launching the System Restore application, which we met at the stage of solving the problem from safe mode. It can be useful in cases where it is not possible to find a single control point in safe mode. It happens that points exist and are created, but the system does not notice them. But here, in the recovery environment, there are no obstacles to this.

The function works exactly the same as in safe or normal modes, so we will not consider it.

The next point is to restore Windows to a working state from an archived copy. If you saved such copies to external media (disks), insert the disk into the drive and specify the path to it.

Most users consider it unnecessary to waste time creating backup images, so if you don’t have such a disk, move on. We have one more tool - the command line. With its help, we can open Explorer and manually restore the system registry.

Once every 10 days, Windows 7 saves copies of the registry files in a separate folder. We can take them and move them to where the current, used registry is. If the failure is due to its damage, the problem will be solved.

Open the command line and launch notepad (for those who don’t know, this is done with the “notepad” command). Click "File" and then "Open." Go through File Explorer to the "Computer" folder. Please note that the drive letters may be different here in the recovery environment.

Open the \\Windows\System32\congfig\regback directory. To see the contents of the folders, in the "File type" field, specify "All files". Copy all 5 files that are there one by one and place them in the \\Windows\System32\congfig folder. This is the registry.

Files of the same name in \\Windows\System32\congfig must first be renamed. For example, add the .OLD extension to them.

Close Explorer. That's all. Restart your computer and try to boot Windows 7 in normal mode. Let's hope you succeed.

If, when you start Windows 7, you see a black screen with a blinking cursor or some message, don’t be too upset. This is a sign that a virus has entered your computer and is making itself known. UNpleasant - yes, but better than the blue screen of death when the system boots. I'll give you some tips on how to remove the black screen when starting Windows.

Virus and black screen in Windows.

Most often, the problem is that the virus corrupts the launch parameters of the system explorer.exe process, that is, it launches it with certain parameters, or modifies the Windows registry in such a way that not the system one, but a third-party explorer.exe is launched.

To make sure that the problem is caused by a malfunction of the explorer.exe shell, call the task manager (Alt+Ctrl+Delete). In the top menu, click “File”, “New task (Run)”. Enter “explorer” or “explorer.exe” and press “Ok” or the “Enter” key.

If the result is a familiar desktop, then everything is clear - the virus is the source of the problem. So we found out that the black Windows screen is caused by a problem in the operation of Explorer.

How to remove the black screen when loading Windows?

If a virus has entered the system, you should remove the program that caused it to appear and scan the operating system with an antivirus. If everything is clean, it is advisable to change the anti-virus program if it did not notice the uninvited guest.

To eliminate the consequences of the virus, you should adjust the Windows registry settings. To open the registry, go to “Start”, command “Run” (or “Task Manager”, “New task (Run)”), write the command “regedit” or “regedt32” and press “Ok” or “Enter”. The Registry Editor will open.

Go to the registry branch HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options

We are looking for subfolders named Explorer or Explorer.exe. If similar folders exist in this branch, you should delete them, since in these folders the virus has written its own paths for launching malicious Explorer with the parameters the virus needs.

I don’t have such a problem at the moment, so there’s nothing to delete.

The second stage of treatment, if there is a black screen when Windows starts.

We are interested in the Shell and UserInit parameters. The Shell parameter should have the value “explorer.exe” and that’s it! No additional characters or paths. The UserInit parameter should be set to "C:\Windows\system32\userinit.exe,"

If these parameters have different values, then correct them to those that should be. If after rebooting the computer or after a while the problem repeats, then you should take care of more reliable computer protection - install the best antivirus and/or firewall (firewall).

How do you like it? -

When starting the operating system, this is one of the most common errors encountered by users. The symptoms of this error in Windows 7 look like this: immediately after the download completes, when a welcome message and a user selection dialog should appear, nothing happens. The screen remains black, no controls are displayed, and no error messages appear. The causes of this problem may be different, and in order to understand how to remove the black screen of Windows 7, you will have to diagnose your computer yourself and look for a solution.

The computer shuts down improperly or the power goes out

If the error when starting Windows 7 is due to an unexpected reason, for example, a power failure, then running the Last Known Good Configuration will help fix this. The essence of the solution is that Windows writes important parameters to a special file and, if the computer starts successfully, marks them as operational. If, after accidentally changing any of these parameters, the system cannot start, then it is possible to use the old configuration. To do this you need to do the following:

turn off the computer;
re-enable it;
wait until the very first screen goes out, which usually displays the name of the motherboard and model or a list of connected devices (hard drives, CD drives);
Hold down the F8 key and wait for a menu to appear with a choice of actions.

Among the boot options displayed, you can see options such as “Safe Mode”, “Safe Mode with Network Driver Support” and others. Find among them the “Last Known Good Configuration” parameter, select it using the arrow keys and press Enter.

When you select this menu item, 90% of Windows startups occur without errors, and the computer returns to normal operation.

Error caused by installing new driver versions

We all love updates. Computer hardware manufacturers are well aware of this and periodically release preliminary versions of drivers, marking them as beta versions. And if, in pursuit of a couple of extra frames per second in your favorite game, you downloaded and installed this version, and the computer greeted you with a black screen when rebooting, then there is a solution for this too. It should be noted that such an error can also appear during a regular update, when you download the final stable version of the drivers, but the installation fails with an error. In any case, if a black screen appears after you install Windows 7, you need to do the following:

following the instructions from the previous section, launch a window with a choice of options for booting your computer;
Use the arrows to select the “Safe Mode with Network Driver Support” option and press Enter.

Next, you need to wait until all unnecessary services and drivers are disabled, including the sound and video card drivers, so that starting the system in this mode is almost always successful if the problem lies in them. You should remove the problematic driver and replace it with a working one. This is done as follows:

Right-click on the “Computer” icon and select “Properties” from the context menu.
In the window that appears, on the left side, find the “Device Manager” item and click on it.
Find the “Video adapters” section in the list of devices and expand it by double-clicking the left mouse button.
Right-click on the name of the video card, open and select “Properties”.
In the window that appears, open the “Driver” tab and select one of the possible actions:

“Roll back” (the current version of the video driver will be deleted and the previous one will be restored);
“Delete” (the current version of the installed driver will be completely removed from the system).

If there is such an opportunity, then it is better to select the “Roll Back” option. In any of the options, after selecting an action, follow the instructions of the “Setup Wizard”, wait for the operation to complete and reboot the computer. It should be remembered that after complete removal from the system, you need to download them again from the manufacturer’s website or install them from the disk that came with the equipment.

Black screen after installing a program

This script is extremely simple and almost exactly repeats the steps in the previous section, so most readers have most likely already guessed how to remove the Windows 7 black screen that appeared after installing new software. The procedure is as follows:

Following the instructions in the previous section, start your computer in safe mode.
Click “Start” -> “Control Panel”.
Find “Programs and Features” and click on it.
A list of programs and components appears, presented in table form. You need to sort the list by installation date by clicking on the corresponding column, then start searching for programs that were installed on the day the black screen appeared.
Select the desired component by clicking once with the left mouse button and click the “Delete” button that appears.

After this, you should restart the computer and evaluate the result.

Black screen caused by changing system settings

There are times when uninstalling the program that caused the black screen to appear is not enough. Many of the programs, as well as official updates from Microsoft, in addition to copying their own files to the hard drive, also change some system parameters. If this is exactly what happened to you, and you don’t know how to remove the Windows 7 black screen and restore old settings, you need to do the following:

following the instructions from the previous section, start the computer in safe mode;
Click the “Start” button and enter the word “recovery” in the search bar;
in the results that appear, select “System Restore” by left-clicking once;
in the window that appears, click “Next”;
select the restore point to which you want to roll back the system and click “Next” again, then “Finish”.

There is no need to worry about the safety of files created later than the date to which we decided to roll back: files created by the user will not be affected during recovery. All that remains is to wait for the operation to complete and boot the computer again.

When nothing helps

If all the methods described above did not help in any way, and you still do not know how to remove the black screen of Windows 7, you should think about radical measures. Ordinary users can turn to specialized service centers for help, where professionals will save you from this error. More advanced users can try reinstalling Windows. Although this measure requires some knowledge and preparation, it guarantees one hundred percent success in getting rid of the black screen. In any of the scenarios you choose, you should back up the necessary files by logging into the system in safe mode, and only then take decisive action.

The desktop is a very important interface and the heart of any personal computer. It is on it that users work with numerous windows and create convenient link icons to organize quick access to the necessary programs. Some users are faced with the fact that the familiar and convenient interface partially stops working - a black screen replaces the wallpaper on the Windows 7 desktop. This article describes what to do in case of such problems.

There are two common types of this problem: the desktop disappears completely or all the shortcuts remain, but a black background appears instead of the usual wallpaper. The first problem is usually caused by damage to the Windows system due to virus attacks or software failures, and the second is a consequence of lack of activation. Next, we discuss in detail how to remove the black screen and return the original background back.

Activation

If you are using an unlicensed copy of Windows, the OS will try in every possible way to notify you about this. Numerous messages and warnings will be displayed on the monitor screen, active programs will be minimized, and a black background with the message “You may be using an unlicensed version” will periodically be installed on the table instead of your image.

There are 2 possibilities to solve this problem. Firstly, you can purchase a key for your version of windows from the Microsoft online store and activate it. To do this, you need to right-click on the “My Computer” shortcut and select “Properties” from the drop-down list. At the very bottom of the window that opens, users can find an activation tool. You just need to enter the purchased key and wait a few minutes for Windows to contact Microsoft's servers.

An alternative method is more popular in Russia - you can use a special free activator program to hack your OS. The effect will be exactly the same, but you can forget about technical support or a free upgrade to Windows 10. A very popular activator is the small utility Chew7. Just download it, press a single button and restart your computer. After restarting, change the black screen to your desired background.

OS damage

If not only the background disappears, but the entire table, along with shortcuts and the quick access panel, most likely your PC was damaged by a virus attack. In this case, you need to solve the current problem, and then immediately protect your computer from viruses.

Since a broken desktop does not allow you to run programs in the usual way, you must resort to an alternative method:

Black screen after loading windows 7, 8, 10 - what to do, the desktop or explorer exe does not start

Sometimes, when starting a computer, the user is greeted with an unpleasant surprise in the form of a black screen. This behavior of the device is caused by:

pirated software;
malware;
incorrect operation of the discrete video card driver;
unfinished installation of updates;
damage to system unit components.

Such a malfunction can occur due to a number of reasons, so finding it is the key to solving the problem.

Starting Safe Mode

To restore correct operation, you will need to start safe mode. You will have to act by touch, which means you need to be careful. After pressing the Backspace or F8 key several times, you need to click on the Tab button 5 times and then press Enter. Next, press Up again, then Enter again, while holding Shift. These actions will cause recovery mode to open. The screen will still remain black, so you won't be able to verify this with your own eyes. Here you need to make the appropriate settings:

three transitions using the Down button, then Enter;
two transitions using the Down button, Enter again;
Next, you need to press the Left key twice;
after that, another transition with the Down and Enter buttons.

If the display display worked correctly, you would see the following picture:

After the above manipulations, the OS will start with the settings marked with arrows in the image. Low resolution may help to see the image.

Troubleshooting

Windows is not activated

This situation is often encountered by users who have a machine with unlicensed software installed.

In order to no longer encounter the annoying notification and the resulting inconveniences, you need to get rid of the corresponding utility. It is included in the package of one of the updates. To do this you will need a separate software solution such as RemoveWAT.

After downloading and launching, you just need to press one button and the problem will be fixed.

Windows accounts - how to delete or change an account

The computer is infected with a virus

The malicious program changes the configuration of deep Windows settings, resulting in a change in the appearance of the interface. If no changes have occurred after removing the malicious program, this does not mean that the destruction of the virus was unsuccessful. The issue may be that the settings were not set before the initial version.

To troubleshoot the problem you must:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\windows NT\CurrentVersion\Winlogon

There are two parameters here, Shell and Userinit, whose default values are explorer.exe and c:\windows\system32\userinit.exe, respectively. If this is not true, you must reset the settings and restart the system for them to take effect.

It is also worth checking the HKEY_CURRENT_USER\SOFTWARE\Microsoft\windows NT\CurrentVersion\Winlogon branch, where such variables should not be located. Otherwise, they are subject to destruction.

Non-working video card drivers

They must be removed, and new ones must be installed in their place. To do this you need:

call the context menu by right-clicking the mouse, pointing it at “Start”;
go to the “Programs and Features” section;
uninstall all elements associated with this video card;

However, this method is unsafe because some components may remain in the system even after removal, which can lead to conflicts during subsequent updates. Therefore, a more competent approach would be to use the specialized Display Driver Uninstaller utility, which is publicly available.

Why does error 651 occur and how to fix it

The final step is to download the driver from the manufacturer’s official website and then install it.

Black desktop without shortcuts

Microsoft works to optimize the software and updates it regularly. During the installation process, the system asks the user not to turn off the computer, but there is not always time or opportunity to do just that.

Terminating updates may result in a black screen upon subsequent boot. This process sometimes lasts up to 30 minutes, which is due to large updates or low hardware performance. When the process is completed, the computer will work properly again.

Computer problems

The first step is to turn off the device. After this, you should inspect the wires and make sure that they are not damaged. You also need to check the cables, as well as their interfaces, for mechanical damage.

The motherboard must also be safe and sound. But even in this case, it can cause a black screen due to a large accumulation of dust.

The board also has a CMOS battery, which is responsible for maintaining the BIOS settings. It may run out of power, preventing the system from booting. In this case, replacing it will solve the problem of the black screen. But most often the solution lies in operating system malfunctions.

If all else fails

There is a procedure for rolling back the OS to the latest working update. To save all files, you need to go to “Control Panel” → “System” → “System Protection” and enable all logical drives in the protection settings. Otherwise, during subsequent recovery, only the system disk will be restored.

Here, restoration occurs by pressing the appropriate button.

A panel will pop up where you need to select the “Next” button at the bottom.

After which a list of available system restore points will open.

Unlocking your phone's pattern key

If you go to “Search for affected programs,” you can get an idea of which applications will be restored and which will be lost.

It is necessary to tick the desired point and click “Next”.

At the very end, you must once again confirm all actions and wait for the process to complete. As a result, the computer will restart and a dialog box with the results will open.

Sometimes after this procedure certain utilities stop working correctly, but such cases are very rare. After installing them again, the applications begin to work properly again.

Desktop won't load. Black screen.

September 8, 2014 Solving standard situations

It turns out that the fact is that the virus makes some amendments to the registry, or rather rewrites the shell. Shell is a shell that initially launches explorer, but the virus reassigns explorer to some random exe file.

Hence, when you turn on the computer, it is not the desktop that appears, but some kind of blocking sign or a black screen.

What to do if the desktop does not load, just a black screen?

This situation can be solved without any particular difficulties: first, press ctrl+alt+delete and call the task manager.

Then we launch a new task: File -> New task -> Regedit -> click “Ok”. With this action we launched the registry editor.

If there is something different there, we fix it immediately.

After the actions taken, there are two scenarios for the development of events: the first - everything worked. This means that after the reboot the desktop appeared and the problems disappeared. We use the computer as before.

The second case - after a reboot there is no desktop again, checking the registry branches showed that the lines have changed again. This indicates that we have a virus on our computer. This virus may be in services or the task scheduler. In this case, it is recommended to thoroughly clean the computer, check for viruses, check startup, delete temporary Internet files, and so on.

On this, I think, we can end the article. Thank you for your attention, subscribe to site updates!

Activating Windows 7 or how to remove the black screen from the desktop

Windows 7 activation has disappeared, your desktop background has become similar to the famous painting by the artist Malevich, a black square? in our case, a black screen. The reason for this problem may be that someone is using a pirated copy of the operating system, or a licensed one, but for some reason the Windows activation key has disappeared and needs to be entered again, but before that you need to do some steps described in this article .

When faced with this problem, you should not worry, because it can be solved with a small number of actions. Let's look at the question of why this happened. When automatically downloading and installing updates, one is downloaded that checks your system for authenticity; it is codenamed KB971033. It is after it is installed that the background scan begins and the identification of a pirated copy of Windows begins. After this, if there is an unlicensed version, a so-called black screen appears, which says that your copy of Windows is not genuine. If the system is licensed, but for some reason the screen turns black, it means the activation key has been lost and you will need to re-enter it, but after some steps.

First, you need to delete the downloaded update; to do this, go to the control panel.

System and security.

Here we need to log into Windows Update.

In the right column at the very bottom, go to the installed updates tab.

And in the list we find what was mentioned above, namely the update for microsoft windows (KB971033). Right-click on it and click delete. But if this update is not listed, it may be hidden. Then we will need to enter the command line and try to get rid of it using a specific command.

Open the start menu, write cmd in the search, right-click on the found file and run it as administrator.

In the line we write the following command wusa.exe /uninstall /kb:971033 and press the enter key. The update should be removed.

After uninstallation, so that this problem no longer bothers us, we will have to find this update using a search and hide it from re-installation, because after uninstallation, it can also be automatically downloaded and installed again. To do this, go to Windows Update and in the right column, click on the item search for updates.

We are waiting for this process to complete. You can have some tea for now.

Afterwards, in the Windows Update Center, we will be provided with some important ones, where they are stored and those that need to be hidden. To do this, go to the important updates tab; as you can see, I have as many as 123 of them.

We find the ones we are interested in, right-click on it and select hide update. After it has disappeared, click ok. Now we can safely install the others provided, after which do not forget to restart the computer. Next, to fully activate Windows, you will need to perform a few more steps, which are described in the article Your copy of Windows 7 is not genuine. Assembly 7600,7601. Also, for users of licensed operating systems who are faced with a black screen problem, this article will help, but instead of the activator, enter your license key again.

Desktop gone black screen

Despite the fact that most system failures are quite normally tolerated by the computer, some of them can bring a lot of problems to the user, take, for example, a situation in which the desktop has disappeared, the black screen obscures the entire area, and the user cannot perform absolutely any actions with the computer. Naturally, the reason for this can be not only a system failure, but also the user’s actions that provoked it, or, say, the actions of viruses or malware, but as a rule, the effect does not change.

In the event that the desktop disappears, the black screen does not disappear when loading, but the user can still see the mouse cursor, then the problem is a system failure, and you can fix it yourself by performing a system rollback. How to do this? It’s quite simple, you just need to hold down the F9 key on the keyboard when you boot the computer, and wait until the boot menu appears with the proposed actions.

In this case, you need to try to boot into safe mode by selecting the appropriate menu item. If this action does not help, you can also try, after booting the computer, press the key combination CTRL+Alt+Del, thereby launching the “Task Manager” system program. If this option for restoring the computer’s functionality worked, then a program window should appear on the screen, in which we need to go to the “Processes” tab and check for the running explorer.exe program. If you couldn’t find one, then the next step is to go to the top “File” menu and select the item called “New task”. In the small window that appears, you need to enter the name of the process to be launched - in our case it will be explorer.exe, and then confirm the actions being performed. If there is already a running process in the “Processes” tab, you can try to terminate it, and after the procedure has been completed, restart it using the same “File” menu.

However, it is worth noting that launching the task manager is not always possible; take, for example, a situation where the administrator has prohibited the launch of this system utility, and then problems with the computer become really serious. Naturally, you can also try to restore the operating system using the installation disk, or, as a last resort, reinstall Windows altogether, but why do this if you can use the help of specialists. The staff of the HelpUser computer center are ready to help you solve any problems related to the inoperability of your computer, in particular the situation when the desktop has disappeared; a black screen does not allow you to run any software, which in every possible way limits the functionality of the computer. Stop trying to figure out the current problem with your computer on your own. When it is enough to contact the qualified computer specialists of our service center, we will provide the highest quality services, and we will do it promptly.
