Remove black screen from windows 7. Black screen when loading Windows: what to do if the computer does not turn on. How to remove black screen from windows

Suddenly after another Windows startup 7 instead of the login screen account or desktop, a black background may appear with a cursor on it. 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. software. This 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 disguise). After all, he is responsible for the graphic Windows interface: everything 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 bad sectors on the hard drive, and even when they contain fragments of system files, the same explorer.exe. Partially damaged planks RAM We won’t ignore it either, but last but not least.

First of all, let's try to start the computer in one of additional options boot - 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.

1. 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 main menu item “File” and call the command “ New task».

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

1. After the BIOS information appears, click F8 until a menu of additional boot options appears.
2. 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.

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

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

1. 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.

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

1. IN text line CMD 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 an installation flash drive, fighting viruses and their consequences, or editing registry entries will help here. In the latter case, you will have to acquire boot disk with an anti-virus program, start from it by selecting the CD/USB with the anti-virus 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.

1. Open the “Run” window through the task manager.

1. We write “regedit” and press Enter.

1. Expand the HKLM branch.
2. Go to the Software section.

1. We follow the path indicated in the screenshot.

1. Open the Shell key editing window.

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

1. Let's reboot.

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

Rollback

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

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

1. 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).

1. Click “Finish”.

1. 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.

1. Let's start in safe mode.
2. Calling context menu my computer and click “Properties”.
3. Click “Device Manager” in the vertical menu on the left.

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

1. 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 installation more old version 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 money could have affected disk space and ease of assembly);
• 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 ones often suffer because of this copies of Windows.
• Virus infection - most likely the malicious program tried to replace itself system files, but for some reason it couldn't and broke the download instead.
• 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 removal 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 latest one will help. successful configuration. The last known known configuration is Windows status, recorded at the time of the previous successful launch. 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.

Click on "Shell" right click mouse 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 by hand or with 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 console Windows utilities- sfc.exe. To do this, open "Start", enter search bar"cmd" and run 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 for overheating GPU 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 Windows recovery from the 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 in case of violation will restore.

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 spend 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 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.

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 for organizing quick access To necessary programs. Some users are faced with the fact that the familiar and convenient interface partially stops working - a black screen replaces the desktop wallpaper windows table 7. 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 windows systems due to virus attacks or software failures, and the second is a consequence of lack of activation. The following describes 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.

Alternative way more popular in Russia - you can use a special free activator program to hack your OS. The effect will be exactly the same, however technical support or free update You can forget about Windows 10. A very popular activator is 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 work drivers discrete video card;
• 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

For recovery 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 the 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 described 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.

Accounting windows records– how to delete or change an entry

The computer is infected with a virus

The malware changes the configurations of deep windows settings, the result of which is 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 problem 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 Company 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.

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 in the protection settings logical drives. 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.

Unlock graphic key phone

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

You must 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?

Is being decided this situation 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 key has disappeared windows activation and you need to enter it 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. At automatic download and installing updates, one is downloaded that checks your system for authenticity, it goes under the code name KB971033. It is after it is installed that the background scan begins and the detection 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.

Desktop gone black screen

Search Computer Articles

Useful articles → Articles on laptop repair

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 actions of the user that provoked this, 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 system failure, and you can eliminate it yourself by performing a system rollback. How to do this? Quite simple, you just need to hold down the F9 key on the keyboard when you boot the computer, and wait until it appears boot menu with suggested 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 causing the startup system program"Task Manager". If this option for restoring the computer’s functionality has worked, then a program window should appear on the screen, in which we need to go to the “Processes” tab and check for running program explorer.exe. If you couldn’t find one, then further action there will be a transition to top menu“File” and selecting 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 end 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 installation disk, or, as a last resort, completely reinstall Windows, 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 is it enough to contact qualified computer specialists from our service center and we will provide the highest quality services, and we will do it quickly.

You need to immediately clarify what “after loading” means. You should not think that this applies to the case when the user turns on the computer, but it does not react to this in any way and the monitor screen remains black, as before turning on the PC. “After loading” means that the user sees on the monitor screen the results of the so-called post (power on self tests), BIOS messages about the computer configuration, the initial Windows 7 welcome screen. But then the usual desktop is displayed (or may not be displayed) in black, and sometimes with some details in the lower right corner. Why doesn't Windows start in its normal mode?

We list the most common causes of a black screen (in order of increasing difficulty in eliminating them):

• Short-term hardware faults, such as power outages.
• Problems with the video card, such as a damaged video driver file.
• Virus attack attempting to damage system files and/or the Windows registry.
• Attempts to update a pirated copy of Windows 7.
• Problems with OS activation.

The simplest reason is a short-term power failure in the electrical network, which can be checked by retrying to turn on the computer and boot Windows 7. If this was the reason for the appearance of the black screen, then when you restart Windows black the screen will disappear and everything will work as expected. Otherwise, the user will have to work a little harder.

In any case, the absence of a normal desktop means that Explorer (explorer.exe) was not launched for one of the reasons given above. First, let's assume that for some reason the explorer does not start, and we will try to start it. To do this:

1. Use the Ctrl+Alt+Delete or Alt+Ctrl+Shift buttons to open the task manager.
2. In its window, open the “Applications” tab.
3. Click on “Create a new task”.
4. In the window with this name, set explorer and click “OK”.

Now you need to restore the normal launch of Explorer so as not to perform the described steps every time you start Windows.

To avoid the hassle of editing system registry, let's use AVZ utility. We launch it and open the “File” item in the main menu, then click on “System Restore”. A window opens with a list of recovery actions. In it, check the items “Restore Explorer settings” and “Restore Explorer launch key”, then click “Perform selected operations”.

Upon completion of AVZ, we reboot, after which the explorer starts normally.

Problems with the video system

Typically, a black screen occurs for two reasons - due to overheating of the video chip or distortion (substitution) of the video card driver file by some malicious application. The first of them is easy to determine if you find out the temperature of the video chip using one of the many computer health monitoring utilities, for example, AIDA64. As a rule, the video chip overheats when the fan blowing on it stops or when it is overloaded with modern “heavy” games. For most video cards, the maximum temperature limit for the video processor is 100 degrees Celsius. If a black screen appears when the PC is running due to overheating of the video processor, then repeated attempts to boot will lead to nothing - you should wait a while for its temperature to drop, then try to boot again.

Black screen as a result of a virus attack

Problems with the video card driver, as a rule, arise either due to the impact of viruses on the video driver file or after an unsuccessful attempt to update it and the resulting incompatibility of the new video driver with the OS version. In any of these cases, you should boot Windows in safe mode. To do this, after turning on the computer, you need to press F8 to make additional boot options appear and select safe mode in it. If after booting in this mode the black screen disappears, then most likely you need to reinstall the video card driver. Of course, reinstalling the video driver is only possible when Windows starts, and other than a black screen, there are no other problems. To reinstall the driver, you need to go to the video card manufacturer’s website, download the most latest version driver and install it. You can also update the driver in another way. You need to go to the device manager, select the desired video adapter in it, right-click on it (RMB) and select “Update drivers” from the menu.

But we can’t close our eyes to possible consequences exposure to viruses. In this case, restoring system files and rolling back to the last working system configuration can help.

Recovering system files

For this purpose it is used system utility sfc. It is launched in a command mode window as an administrator by typing the command sfc /scannow. This utility will check system files for corruption and, if necessary, restore them. Sometimes it may ask you to install a disk with a Windows 7 distribution, but usually this does not happen, and the files are restored from their copies on the hard drive.

Last Known Good Configuration

This feature is available in the Advanced Boot Options menu, which you can access by holding down the F8 key immediately after turning on the computer.

It is possible that restoring a successful configuration will not help, since it may also be corrupted by a virus attack. It remains to apply the following recovery option.

Rollback to one of the previously created restore points

This can restore the contents of system files and the registry and get rid of their corruption and deletion as a result of viruses. To perform such a recovery, the following steps are required.

We boot into safe mode, call up the control panel, in which we select the “System” item. A window appears, on the left side of which select “System protection”. After this, we are presented with a window that looks like:

If the system partition hard drive In the “Protection” column, “Enabled” is not indicated, then there is no point in continuing further, since there are no rollback points due to the fact that the user did not bother about it. However, let’s assume the opposite - the user showed concern for the “health” of his PC and protection system disk installed. Then you can click on “Restore” and get a window asking you to select one of the rollback points:

This photo shows a point automatically created by the system during installation Avast antivirus. If you check the “Show other restore points” checkbox, you can select earlier rollback points. You should choose the point at which there was maximum stable work systems. Having set the rollback point, click “Next”, after which the system recovery process starts, which ends with a reboot. You can be sure that there will be no problem with a black screen when booting the system.

Problems with activating and updating a pirated copy of Windows 7

These two points of the reasons for the appearance of a black screen are closely related, so the author of the article combined them into one point.

It will not be a big secret to say that many users install unlicensed Windows versions 7. Therefore, they may periodically experience a black screen after installing system updates distributed by Microsoft. Authentication occurs with every update installed system, and in the case of a “pirate”, when the system boots, the user receives a black screen, in the lower right corner of which there is an inscription stating that a fake copy of the operating system has been installed that has not passed authentication. Moreover, some curious but inexperienced users try to verify its authenticity with their own hands, and as a reward for their curiosity they receive a black screen. Why, because he knows that this is a pirated version.

In this case, you can get rid of the black screen by following these steps. You need to go to the “Center” through the control panel Windows updates,” in which you need to click “View update log”, and in it “Installed updates”. In the window that opens, the user will see all installed updates, among which he needs to find KB971033, remove it and reboot.

To prevent this from happening again, this update should be disabled altogether. To do this, in the Update Center, select “Search for updates” and search for this ill-fated update. Then you need to right-click on it and select “Hide update” from the menu. In addition, you need to remove the checkmark in the small window next to the update name, then click “OK”.

Well, in order to finally “discourage” the system from checking authenticity with each update, it is recommended to edit the system hosts file, which is located on system partition in the Windows/System32/drivers/etc directory, placing the line 127.0.0.1 validation.sls.microsoft.com.

Sometimes, when loading the system, users encounter such an unpleasant problem as the appearance of a black screen on which only the mouse cursor is displayed. Thus, it is simply impossible to work with a PC. Let's take a look at what are the most effective ways Troubleshoot this problem in Windows 7.

Most often, a black screen appears after the welcome screen has been opened. Windows window. In the vast majority of cases, this problem is caused by an incorrectly installed Windows update, when some kind of failure occurred during installation. This makes it impossible to start system application explorer.exe ( "Windows Explorer"), which is responsible for displaying the graphical shell of the OS. Therefore, instead of a picture, you just see 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 options to resolve this issue.

Method 1: Restoring the OS from “Safe Mode”

The first method involves using "Command line", launched in « Safe Mode» , to activate the explorer.exe application and then roll back the OS to a working state. This method can be used when the device has a restore point created before the black screen problem appeared.

1. First of all, you need to go to "Safe Mode". To do this, restart the computer and when you turn it on again after sound signal hold down the button F8.



2. The system boot type selection shell will launch. First of all, try activating the Last Known Good Configuration by using the arrow keys to select the indicated option and press Enter. If the computer starts normally, then consider that your problem is solved.

   

   But in most cases this does not help. Then in the boot type shell, select the option that requires activation "Safe Mode" with support "Command line". Next click Enter.



3. The system will start, but only a window will open "Command line". Type into it:

   After entering, click Enter.



4. The entered command activates "Conductor" and the graphical shell of the system will begin to display. But if you try to restart again, the problem will return, which means that you should roll back the system to a working state. To activate a tool that can perform this procedure, click "Start" and go to "All programs".



5. Open the folder "Standard".



6. Login to the directory "Service".



7. In the list of tools that opens, select "System Restore".



8. The starting shell of the standard tool for resuscitating the OS is activated, where you should click "Next".



9. Then a window opens where you should select the point to which the rollback will be performed. We recommend using the most recent option, but which must have been created before the problem with the black screen appeared. To expand your choice, check the box "Show others...". After highlighting the name of the optimal point, press "Next".



10. In the next window you only need to click "Ready".



11. A dialog box will open where you must confirm your intentions by clicking "Yes".



12. The rollback operation will begin. At this time, the PC will restart. After turning it on, the system should start in standard mode, and the problem with the black screen should disappear.

Method 2: Recovering OS files

But there are cases when the OS files are so badly damaged that the system does not boot even in "Safe Mode". It is also impossible to exclude the possibility that you simply may not have the required restore point on your PC. Then you should perform a more complex procedure to resuscitate the computer.

1. When you start your PC, go to the boot type selection window, as demonstrated in the previous method. But this time, choose from the items presented "Troubleshooting..." and press Enter.



2. The recovery environment window opens. Select from the list of tools « Command line» .



3. The interface opens "Command line". In it, enter the following expression:

   Be sure to click Enter.



4. The shell will start "Registry Editor". But you need to remember that its sections will not relate to the current OS, but to the recovery environment. Therefore, you need to additionally connect the registry hive of the Windows 7 that needs to be fixed. For this purpose in "Editor" select a section "HKEY_LOCAL_MACHINE".



5. After that press "File". In the list that opens, select "Load bush...".



6. The hive loading window opens. In it, go to the partition of the disk on which your operating system is located. Next, go sequentially to the directories "Windows", "System32" And "Config". If, for example, your OS is located on drive C, then the full path to go to should be as follows:

   C:\Windows\system32\config

   In the directory that opens, select the file called "SYSTEM" and press "Open".



. Enter any arbitrary name in Latin or using numbers in its only field. Next click "OK".



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



8. In the directory that opens, select the folder "Setup". On the right side of the window, among the elements that appear, find the parameter "CmdLine" and click on it.



9. In the window that opens, enter the value in the field "cmd.exe" without quotes, then click "OK".



10. Now go to the parameter properties window "SetupType" by clicking on the corresponding element.



11. In the window that opens, replace the current value in the field with "2" without quotes and click "OK".



12. After that, go back to the window "Registry Editor" to the section that you previously connected and select it.



13. Click "File" and select from the drop-down list "Unload the bush...".



14. A dialog box will open asking you to confirm your decision by clicking "Yes".



15. Then close the window "Registry Editor" And "Command line", thus returning to the main menu of the recovery environment. Click here on the button.



16. After rebooting the PC will automatically open "Command line". Enter the command there:

    Click here Enter.



17. The computer will be checked for the integrity of the file structure. If violations are detected, the recovery procedure for the corresponding element is automatically activated.

    

18. Once the recovery is complete, enter the following command:

    shutdown /r /t 0

    Click Enter.



19. The computer will restart and turn on normally. It is important to take into account that if the system files were damaged, which caused the black screen, then it is quite possible that the root cause of this could be a viral infection of the PC. Therefore, immediately after restoring your computer, check it antivirus utility(not the standard antivirus). For example, you can use Dr.Web CureIt.

If none of the above methods helped, then in this case you can perform Windows installation 7 over the working operating system with all settings saved, or complete reinstallation OS. If these actions do not produce results, there is a high probability that one of the hardware components of the computer has failed, for example, hard drive. In this case, it is necessary to repair or replace the broken device.

The main reason why a black screen appears when the system boots in Windows 7 is incorrect installed update. This problem“cured” by rolling back the OS to a previously created point or performing a file recovery procedure. More radical actions also involve reinstalling the system or replacing elements of the computer hardware.
