Dark screen in Windows 10. Why does a black screen and mouse cursor appear? Reasons and their solution

Recently I noticed a strange bug with loading Windows 10 on my laptop. It happens in the following situation.

1. Windows updates are installed on the computer.
2. Next, the computer goes into reboot.
3. The computer starts to boot
4. A blue image appears Windows logo in the middle of the screen
5. Then the screen turns black and a spinning circle appears in the middle at the bottom of the screen and spins endlessly. In this case, first you can see a blinking activity indicator on the computer case hard drive, but after some time the disk activity disappears, and the circle on the screen continues to rotate endlessly.

At first I interrupted this "freezing" by forced shutdown computer by holding down the power button for more than 6 seconds. When rebooting, this picture usually repeated again and I had to forcefully turn off the PC again. After 5-10 attempts at such violence on the computer, it was still possible to load Windows and after that, further downloads took place without problems until the next updates were installed (we could not find out which ones exactly). When some special updates were installed again, my PC again froze when loading on a black background.

This chaos continued until one day I decided to disconnect all peripheral devices from the computer, namely: 2 external monitors, USB camera and USB adapter for mouse and Logitech keyboards Unifying USB Receiver. The computer immediately froze and Windows continued loading. This turned out to be the whole point USB adapter Logitech Unifying USB Receiver. If it is connected to USB port, then Windows periodically after some updates freezes on a black background, and if it is not connected to the USB port, then no problems appear with loading.

Advice: if you have problems loading your PC or instability of your PC, try to turn off all peripherals or reduce them to a minimum, leaving, for example, only a wired keyboard. If you have a laptop, you can turn off everything except charging. If you have system unit and you can open it, then try to pull everything out in the same way additional fees, connected to PCI slots,PCI-E. Of course, if motherboard If there is no built-in video card, then it makes no sense to remove the video card from PCI-E, otherwise you will not see anything on the monitor. If there is another video card, try installing another one. If the shutdown additional devices solved your problem, then next time try to disable them one by one to determine exactly which device is “buggy”.

Now, when Windows freezes on boot, I do the following:

1. I pull out the Logitech Unifying USB Receiver from the USB port
2. I'm waiting full load Windows, without connecting the USB Receiver, otherwise it causes strange brakes in the OS
3. I send Windows to reboot
4. Wait for Windows to fully load
5. Now I connect the Logitech Unifying USB Receiver to the USB port
6. I continue to work on the PC

I hope this solution will help all those who have a similar problem.

What does a black screen mean when you turn on your computer?

Yes, anything, starting with lost drivers and ending with the next influx harmful viruses and other software from dubious sources.

If you decide to work, and when you turn it on you see a funny monochrome spectacle, then you’ll have to look for alternative source for forays into the Internet to know what to do and where to run.

There may be several options:

• activation;
• drivers;
• registry;
• viruses.

We will try to consider each point in as much detail as possible. To begin with, you should switch to Safe Startup mode to try to get to your system files.

We turn off our machine, reboot and press F8 (for alternative combinations, use Shift/Del/Fn+F8) until we hit the boot window.

If the machine functions quite adequately in this mode, it means that the system settings have been damaged, in particular, viruses have created “holes” in the registry, updates have not been installed correctly, as is often the case with them, or the drivers for the video card have died.

Separately, it is worth highlighting the non-activated version of the OS. It will work, but the black desktop and the intrusive inscription at the bottom of the screen will get boring very quickly.

If the system does not respond to your startup attempts, try switching it to sleep mode, or use the original boot disk, if there is one.

Windows activation

If you found a pirated OS somewhere, installed it and accidentally “released” it on the network, enabling the appropriate access to updates, and then see a black screen on your desktop, it means that the developers have partially limited your rights, and the system has not been authenticated.

Getting rid of the “problem” is not so difficult, but you won’t be able to do it without an activation key or a special activator program. Looking for similar solution on the Internet or from friends.

Important! The Serial Key must be working and valid, otherwise nothing will work out for you. We paste it into the appropriate field and wait for the system to update itself again and remove the ill-fated inscription.

Drivers

The diagnostic tool will launch. We select the second tab, where the name of the video card, model index and developer company are described in great detail.

Guided by this simple knowledge, we go to the desired source and select the appropriate type of driver.

Although here you may encounter another problem - what OS do you have. In the vast majority of cases this is Windows.

For owners of a “window” system, you need to do the following: We register the same DxDiag and look at the first tab.

IN in this case Win7 64 is used. You may have any other version of the system with a different bit depth.

Rely on your indicators, on the basis of which the appropriate driver from nVidia or AMD is selected.

If after installation the black screen problem has resolved itself, you can congratulate yourself.

Debugging via the registry

When the OS starts, the black screen may “light up” and if there are problems in . You need to find the damaged file and clean it of third-party content.

We will need the Start-Run link again. You need to look for a team regedit.

Among the abundance of folders, you will need to look for the one that is located at the appropriate address.

It's entirely possible that someone or something has "modified" the Shell file that needs to be fixed.

Double-click on it and delete absolutely all the data that is in the “value” field.

We register "explorer.exe" and save the changes. Now the only thing left to do is restart the car, only now not in safe mode, but in normal mode.

If your actions were correct, then this debugging will bring everything to a divine state.

Otherwise, you have the wrong folder, so take a closer look at the location path key file.

This way you can cure any version of the OS, but as practice shows, a black screen when installing Windows 10 often crashes due to a driver conflict AMD video cards.

For some reason, the system does not entirely welcome them and in every possible way rejects certain versions. Download the current “firewood” from the red ones, reboot and try your luck again.

From version to version, the “jambs” of Windows remain familiar.

The methods of dealing with them also do not change from year to year.

If your computer suddenly starts showing a black screen, don’t despair, because the problem is common (relatively) and does not require complete reinstallation systems.

Sometimes Microsoft OS users encounter a problem when After loading Windows only black screen and cursor mice. The symptom is quite well known - the system process “explorer.exe” cannot start. There may be several reasons: a virus or vice versa - an antivirus (Avast), problems with hard drive etc. Quite often fix black screen on startup you can do it in a minute without any third-party utilities.

As already mentioned in the title, the reason for this behavior is process startup error, which is responsible, among other things, for displaying the desktop, its elements and the panel with the Start button. In this recovery guide, we'll look at two popular reasons why When loading Windows you can see a black screen and cursor instead of a desktop. One of the reasons in some cases is the popular Avast antivirus , which, for reasons known only to him, blocks “ explorer.exe" In the second case, you will have to slightly edit the system registry. In both situations Windows work is being restored very easy.

Avast is the culprit behind the black screen when loading Windows.

So after Windows has booted, but on the screen there is only a black “Malevich square”, along which an “abstract cockroach” is running - the mouse cursor, do the following:

• 1. Press the world-famous combination of buttons “ Ctrl+Alt+Del" and select "Launch task manager" from the list.
• 2. After the task manager window appears, find in the list of processes “ avast"(Processes tab) and from the context menu (right-click on the process) select "Open file location".
• 3. You will see a window with a folder where Avast antivirus is installed. Find the “AvastUI” file in it and run it (double click or “Enter”). The main antivirus window should open.
• 4. Go to the tab “ Safety", in the list on the left select " Antivirus", and among the menu items that appear, click on " Behavior Screen».
• 5. Open Screen Settings and add to reliable processes « c:\windows\explorer.exe"(use the "Browse" button). We confirm our actions with the “OK” button.
• 6. Restart your computer: click “ again” Ctrl+Alt+Del» and find the corresponding icon on the screen that appears.

If the Avast antivirus was the culprit, then after following the steps from the instructions for solving the problem black screen and mouse cursor when Windows startup – next boot operating system should be successful. It is quite possible that the problem has already been solved by the Avast developers, but the process of adding the program to the “trusted” ones may still be useful. Moreover, it is not known how the antivirus will react to the upcoming Windows 10.

In case you use another antivirus, then try to find in its settings a similar item for creating a list of “trusted”, “reliable”, “ignored”, etc. applications that should not be scanned by this antivirus. If the antivirus is to blame, then black screen with cursor when loading Shouldn't bother you anymore. A defender who reacts so inadequately to popular programs, most likely, will receive a corresponding update in the next few days (and maybe hours). It is quite possible that it will be received automatically if you have an Internet connection and the configured function for updating the antivirus over the Internet. Otherwise, it is recommended to download the updated version from the official website.

Not always errors and similar situations when Windows starts caused by antivirus. There may also be problems with the equipment. The review was recently published. But next we will consider a solution when, in the current situation ( Only the mouse cursor is on the screen) Incorrect Windows registry settings are to blame.

What should I do if when I start Windows, all I can see is a black screen and a mouse? We edit the system registry.

The first step is exactly the same as in the case of an antivirus: you need to open , use it to launch registry editor and check/correct a couple of Windows registry values.

• 1. Able black screen press the world-famous “Ctrl+Alt+Del” button combination and select “Launch task manager” from the list.
• 2. After the task manager window appears in top menu"File" select "New task (Run)...". The “Create” window will appear. new task" In the "Open" field, enter the command "" (without quotes). A Registry Editor window will open.
• 3. B left side window, go to the section (something like “folders” in Explorer) called “ HKEY_LOCAL_MACHINE" Expand it and go to the subsection " SOFTWARE" In the same way, get to the section “ HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon».
• 4. On the right side of the window you will see a list of parameters. Find the option called " Shell" Its meaning there should be a line "explorer.exe". If this is not the case, then after double-clicking on it, set the specified value. In the event that the “Shell” parameter is missing altogether, then create it, by selecting “Create” – “String parameter” from the context menu of the “Logon” section. Specify the name of the new parameter (“Shell”) and then double click set the value to (“explorer.exe”).
• 5. As in point 3, go to the “ HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" Here right side shouldn't contain the "Shell" parameter. If there is one, then you should delete it through context menu or the “Delete” button on the keyboard.

The two methods above will help you restore Windows if, when booting, black screen and mouse cursor. Changing the “Shell” setting often indicates that the computer has been infected with a virus. It is quite possible that he has already been rendered harmless. installed antivirus, but traces of his activity (change to “Shell”) could well remain in the system.

Sometimes it happens that as a result of the supposedly successful installation of Windows 10 OS or its update, after a reboot, instead of correct operation system, the user sees a black screen in front of him. This is a rather unpleasant situation that requires certain actions.

Let's try to figure out why the black screen appears and how we can fix this problem.

This problem is difficult to diagnose and the user simply needs to try one by one different ways its elimination.

Method 1: Waiting

No matter how funny it may sound, it is a fairly common situation when a black screen occurs after installing updates and rebooting personal computer. If before turning off the PC there was a message that an update was being installed, and after rebooting a black window with a cursor or rotating dots appeared, then you need to wait (no more than 30 minutes) until the system is updated. If nothing has changed during this time, use other options to solve the problem.

Method 2: Checking the Monitor

If absolutely nothing is displayed on the screen, then you should check the serviceability of the display. If possible, connect the monitor to another device and see if it displays anything. At the same time, the problem may be another monitor or TV connected to the PC. In this case, the video signal can be sent to the second device, so nothing will appear on the main monitor.

Method 3: Check your system for viruses

Malicious software is also pretty common cause black screen appears in Windows 10, so one more possible option The solution to the problem is to check the system for viruses. This can be done either using Live disks (for example, from Dr.Web, which can be downloaded from their official website), or in safe mode using ordinary portable utilities (,).

What safe mode is and how you can get into it can be read from the publication below.

Viruses can result in damage to important system files and removing malware alone will not be enough. In this case, it is necessary to reinstall the system or roll it back to the latest stable version.

Method 4: Reinstalling drivers

A fairly common cause of a malfunction that manifests itself in the form of a black screen is a malfunction of the video card driver. Of course, just looking at the monitor you cannot say that this is the reason, but if all the previously described methods did not help solve the problem, then you can try reinstalling the video card drivers. This task is for inexperienced user quite difficult, since the most easy way to do this, go into safe mode, which is disabled by default in Windows 10, without graphic pictures before my eyes. In other words, everything will have to be done blindly. Most best option such work looks like this.

1. Turn on your PC.
2. Wait for some time (required for the system to boot).
3. If a password is set, blind enter the required characters.
4. Wait a little longer.
5. Press the key combination "Win+X".
6. Click the button "up arrow" 8 times in a row and then "Enter". This kind of action will trigger "Command line".
7. Enter the command bcdedit /set (default) safeboot network and the key "Enter".
8. After this, you must also type shutdown /r and also press "Enter".
9. Wait for your PC to respond beep and start counting to 15. After this time, press "Enter".

As a result, Windows 10 will start in safe mode. Next, you can begin removing drivers. You can read how to do this correctly in the publication at the link below.

Method 5: System Rollback

If none of the above methods helped get rid of the problem, then the only way out is to roll back the system from a backup to the previous one working version, where there was no black screen. More details about backups You can find out from the article on our website.

The causes of a black screen are quite varied, so identifying a specific one is sometimes quite difficult. But despite the cause of the malfunction, in most cases, the problem can be solved using the above methods.

Upgrading to Windows 10 is enough simple procedure and on most computers everything works without any problems. However, there are exceptions to this rule and it may happen that after updating and logging in we will be greeted with a black screen. What then should you do when a black screen appears when loading windows 10?

Unfortunately, in my case, the system did not update as I expected. Although the system detected updates and performed quick installation, after its launch, troubles began. Windows didn't boot system shell, instead a mouse cursor appeared on a black screen and a message was displayed in the upper left corner stating that the desktop personalization service was not responding.

How to fix black screen after upgrading to Windows 10

This error appeared earlier when installing and updating in Windows versions 10 Technical Preview. Fortunately, it is not (in most cases) a fatal error and can be fixed without losing any data on your computer. Since the mouse cursor is working and the system is responding to key combinations, we will still be able to call individual functions to diagnose the error and make certain adjustments.

Step 1: Scan the disk using the sfc /scannow command

Press combination CTRL keys+ Shift + Esc to bring up the Task Manager window. There is also another way to launch the Task Manager in Windows 10: right-click on the Start icon and you will see the corresponding item in the pop-up menu.

In the manager window, select "File - Run new task." A window will appear in which you can call up individual programs.

Enter the “cmd” command in it, and then select the “Create a task with administrator rights” option. So we called command line in administrator mode.

Enter in the console sfc team/scannow and confirm your choice by pressing Enter.

It will begin hard check disk for errors - if a malfunction is detected, the system will automatically try to fix the problem. After checking, you can proceed to the next step.

Step 2: Removing the key responsible for updating the desktop from the system registry

IN system registry during an update or Windows installations 10 creates a key that is responsible for setting up the desktop. A black screen indicates that something went wrong and prevented the setup from being completed. In this case, you need to remove the key, which may be damaged and causing the error.

Go to the Task Manager again and select “File - Run New Task”. This time enter the regedit command and confirm with OK.

In Registry Editor, navigate to the following path:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ActiveSetup\Installed Components\

In the "Installed Components" section you will find a list of keys with random names. We need to find a key that has a default value named "Windows Desktop Update". To do this, you will have to check each key until you find the specified value.

Once you have found it, you need to remove it. Right-click on the found key and select Delete in the menu that appears. After removal, you can close the Registry Editor.

Step 3: Restart your computer in Safe Mode

After these steps, you need to restart the computer in safe mode so that the system can boot into the system with a minimum number of processes enabled.

To do this, in the Task Manager, open “File - Run new task” and type the msconfig command. Confirm its launch using the OK button.

In the new window, go to the Downloads menu and at the bottom select " Safe Mode" Leave the remaining options as default and restart the computer.

The computer will start in safe mode and after logging into Windows system 10 the desktop should appear with a taskbar and a Start menu. Now you need to turn off safe mode. Enter the msconfig command again in the Manager, go to Downloads and uncheck the “Safe Mode” checkbox. After reboot Windows computer 10 should boot normally and the desktop will appear instead of a black screen.
