There is a very common problem among PC owners - you turn on the computer and see black screen on boot.
What are the reasons for this failure and what to do in this situation is the main topic of this article.
System boot problems
The problem has a wide range of factors that provoke it.
In addition, the black screen can also be displayed in different ways, for example with or without a cursor.
Let's take a closer look at the main causes of breakdown:
- Internal error in work operating system, because of which it fails to adequately interact with the graphical environment;
- Failure of the driver for the video card (incompatibility with the installed version Windows);
- Breakdown of the computer's internal storage;
- Critical disruption to Windows OC that prevents it from loading adequately even in Safe Mode;
- Other conflicts of the hardware department of the PC;
- The operating system is unable to wake up from sleep mode.
Boot Windows in Safe Mode
Initially, you should try to safely boot the system.
Disconnect from computer external devices, as well as flash media, which could also be the cause of the conflict.
Turn off your computer to terminate all processes causing the black screen.
Then restart it, at the very beginning of which be sure to press the F8 button on the keyboard (Delete, Shift + F8 - depending on the installed operating system).
In the Advanced Boot Options window, select the option you want.
In this case, Safe Mode.
If the computer starts up in this mode without any problems, then we can assume that the settings of the system itself have failed.
This additionally includes the appearance of an error after the next update in the OS registry, and incorrect operation of drivers.
Here, activating the operating system is the first step towards fixing the problem.
Many people use an unlicensed copy of the operating system, the next update of which sometimes ends up with a black screen.
This is due to the impossibility of passing the "pirated copy" of identification on the Microsoft website.
If so, then after booting in Safe Mode, you will see a warning on the screen about using an unofficial version, which should be licensed.
To get rid of the problem - activate your copy of the operating system.
Equipment malfunctions
Monitor and system unit
A black screen may be caused by equipment problems.
For example, due to poor contact of the monitor with the system unit, when a signal from the video card is not received by it.
The monitor's network cable is not making good contact with the outlet
In this case, check the quality of all connections, and if there is any external damage to the screen, due to which the image may be missing.
If such a problem occurs on a laptop, then the reason is almost always not related to the display, since in order to damage it, it must be subjected to strong mechanical impact, for example, falling or hitting.
In this case, the deformation of the monitor will be visible to the naked eye: color stripes will be traced, areas with dead pixels, scratches, etc.
On a computer, a black screen when logging into the system can cause breakdown of one of the components of the system unit, so it will need to be studied in detail.
First of all, attention should be paid to the video card, namely the reliability and density of its attachment in the slot motherboardas well as the stability of the supply voltage and cooling (if not passive).
Checking the performance of the video card drivers
Check the status of the video card drivers that may conflict with the system.
To do this, it is necessary to re-launch the operating system in safe mode by activating the video mode support item with a low screen resolution in its menu.
After logging in, go to the control panel.
To do this, right-click on the menu "Start" and select from the list that appears "Device Manager" .
Select there in the section "Video adapters" installed video card and go to its properties window.
In the tab "Driver" click on the button Delete.
Then restart your computer and install the factory drivers that come with your video card.
You can go to the manufacturer's website and download the latest version there.
If you do not know which drivers to look for, call the tab « Execute» using the keyboard shortcut Win + R.
In the field to open, enter
and click on the " OK».
In this case, the DirectX Diagnostic Tool window will appear, which will display the name of the available video card.
Using the information received, it is quite easy to download the necessary ones.
Elimination of a possible conflict of software components
A characteristic feature of this option is that after several attempts to restart, the computer still manages to start.
The method of "treatment" will be approximately similar to the previous case, the only difference here is what is needed in the section windows configuration select item "Include safe mode» .
Then, in the top line, sort the installed software by download date.
Now, after looking at the list of installed software, you need to find the culprit and remove it.
This is best done through third party programssuch as CCleaner, because with it you will get rid of all residual elements after deletion.
To get rid of the suspicious program, you need to go to the section "Service - Remove Programs" and choose the option you want.
Motherboard driver
A black screen is sometimes the result of a conflict between the mother's drivers and the system.
Repeat the previously described steps to remove and install a workable program in their place.
Be careful when working with drivers, otherwise you will not avoid a complete reinstallation of the operating system.
To protect yourself from this, set a checkpoint to which, if necessary, you can roll back the system.
In the event that, after replacing the drivers, the black screen periodically continues to remind of itself, continue to search for the cause.
Try to remove all programs that can cause system conflict, as well as test your computer for various malware.
Start the system again in safe mode and open the control panel by right-clicking on the " Start».
From the list present, select " Programs and Features"And click on it.
Carefully analyze which programs have been installed recently and may cause a conflict.
Remove them using standard Windows features or a third-party program.
One of the best currently is CCleaner.
The program is understandable and efficient enough to remove all accumulated file junk.
All you have to do is check the boxes in the section « Cleaning» opposite the desired items.
After the analysis carried out by the program, press the button « Cleaning» and wait for it to complete.
By going to the tab « Service» , you are free to choose the programs to be removed.
Select the one you need and click on the button « Uninstall» .
Registry recovery
Intermittent black screen may also be due to some data corruption system registry malware.
To get rid of this, you should restore it to a fully working state.
To do this, open « Task Manager» using the keyboard shortcut Ctrl + Shift + Esc.
In the window that appears, go to the applications tab. Here you need to create a new task by clicking on the button of the same name and entering a value in a special field
Windows 10 makes this easier. Right click on the menu « Start» and in the list that appears, select the item « Execute» .
In the input field, write
Regedit
and press the button OK.
Windows Registry
The Registry Editor will open.
In it you need to find a line with the name " Shell"And click on it twice.
When the window for changing the string parameter appears, delete all entries of the parameter " Shell", And in the vacant field enter
Explorer.exe
After that, click on the button OKsaving the changes you made.
The final step is to reboot the computer, allowing the settings to take effect and debugging the registry.
If done correctly, the registry will be restored and the black screen will no longer appear.
System recovery with third-party programs
Debug work explorer.exe you can not only manually, but also with the help of a small utility AVZ.
You must first download and install it on your computer.
The main window of this anti-virus utility contains several menu items, including the following:
- File;
- Service;
- AVZGuard;
- AVZPM;
- Reference.
Choose an item « File» , and from the list that appears - » .
After that, the settings window for the restore function will open, in which you need to activate the 8th and 16th lines (restore the Explorer settings and restore the Explorer launch key).
By checking the boxes opposite them, it remains to click on the button Perform marked operations and wait for the end of the process. Upon completion, be sure to restart your computer.
Startup
It often happens that a program in startup, or a very large number of them, can cause a black screen to appear periodically.
Reduce the number of starting from Windows programs to a minimum and, if this does not remove the existing error, then at least speed up the launch of the operating system itself.
This condition can be easily met using the command
Msconfig
which should be registered in the menu window "Run" .
By clicking on the OK button you will be taken to the window Windows Task Manager , in which you should go to the tab.
This tab displays all the programs participating in the joint launch with the OS.
Select all unnecessary programs and click on the Disable button.
System rollback
Solving the black screen problem often a simple rollback of the operating system to a restore point will help.
Although quite often users disable this function, considering it almost useless.
But with its help it is sometimes quite possible to avoid reinstalling Windows, returning to the moment of maximum stable work.
It is quite possible to perform this operation after loading the safe mode.
Conflict with antivirus software
The inability to launch often provokes a conflict between the OS and the installed antivirus program.
The latter sometimes erroneously blocks various system files.
To return the computer to a normal working state, you will need to complete some antivirus processes.
Using a combination of buttons C trl+ Shift + Esc open the Task Manager window and select on the tab " Processes»Those related to antivirus - complete them.
Remember that this is a temporary measure and with the next start of the system they will be started again. To avoid repetition, you should create specific exceptions for your antivirus application.
If you use the AVAST program, it will look like this.
Go to the application settings window and select the active protection item.
Then go to the screen tab file system and select the section in it "Settings" .
On the left side of this section, find the item "Exceptions" and click on it.
Add the following values \u200b\u200bto the input field - "C: \\ Windows \\ explorer.exe" and "C: \\ Windows \\ immersiveControlPanel \\ systemSettings.exe"... Then click on the OK button.
In order to start the explorer.exe process, you must use the menu "Run" and enter the name of the process in a special window.
After clicking OK, you need to restart your computer.
Checking and removing viruses
Malware is the culprit in operating system failure like no other.
Therefore, it is necessary to check not only the section with the system, but all hard disk to identify them.
Can different ways carry out such a check.
One of them would be using the utility 4MRecoverwhich is present on boot disk LiveCD 4MRescueKit.
Another option is check hard disk on another computer with good anti-virus protection.
True, this is not very convenient, since you will have to remove the cover of the system unit and disconnect the drive itself.
DownloadBlack screen appears during Windows reinstallation
In this case, there are several solutions at once:
1. Use a different media with the image for installation, or write another version of the OS to it
2. Checking the volume with Windows for bad sectors, since they can disrupt the installation process.
The flash drive or disk must be checked for other types of damage. For example, mechanical;
3. It is worth trying to select another local disk as the system one.
Fight against viruses and other malware
Fraudulent software is quite advanced and damages not only user data, but also important system utilities.
In this case, the cursor also appears occasionally, moreover, it is even manageable.
A virus attack may not be confirmed, but it's worth a try.
In our time on the market antivirus softwarethere are a lot of components, but it will be best to use the development of the laboratory Dr. Web entitled CureIt.
With it, the user is provided with the function of superficial analysis of files on a PC, and a more detailed check, this is how the start menu of the utility looks like:
If Windows does not load, you need to take hDD and connect it to another PC.
Using this program is very simple: you just need to "HDD" as well as the strength of the check.
If the above technique did not help, the reason should be looked for in something else.
DownloadCreate a recovery USB drive and reinstall Windows
One of the toughest methods among all those proposed is a complete reinstallation of the existing OS to a more stable one.
In our time, the need to write an image to disk, now it is enough to simply create a flash drive with an installation program.
This can be done simply using any specialized program.
Rufus
One of the best available is Rufus.
The utility, despite the scarcity of the external interface, copes well with its purpose.
Using it is very simple: you just need to go to the section "Device" select an NTFS formatted boot volume and image file, and then click "Start" ... View start page applications.
UltrISO
This program has a slightly larger arsenal of tasks than the previous one.
For creating bootable USB drive it must be reformatted to NTFS.
After running the program, you will see the following window:
3. Choose the path to the image;
The worst case scenario when a black screen appears is a hard drive failure.
Initially, this reason can be answered if the cursor is visible on the display, as this means that the device is functioning.
If you see a completely dark screen, most likely this is provoked by the fact that the drive simply does not work and, as a result, is not displayed in the system.
Definition of bad sectors
It should be noted right away that broken sectors almost impossible to recover.
However, they can be closed for reading and writing, so they will not interfere with further work. The origin of this damage is of two nature:
- Logical... It occurs due to the mismatch of the ECC code with the contents of the sector. In fact, these fragments are not broken, but only temporarily unreadable, so they must be repaired;
- Mechanical... Broken sectors of this kind are caused by strong blows or strong shocks during operation. These particles are permanently out of order and cannot be repaired.
For retrieval and restoration in the operating room windows system there is a built-in check utility - CHKDSK.
This component is launched in two ways:
- Through the command line... To do this, call the Run menu with the Win + R combination and enter cmd into it. In the window that opens, enter the following values: CHKDSK C: / where C is the letter designation of the local disk being checked;
- Through section properties in the tab "Computer" .
If the check shows that there are bad sectors in the PC memory, the utility will offer to restore or close them.
To prevent the occurrence of the damage in question, it is necessary to periodically clean the hard drives from accumulated dust and dirt.
Besides, solid state drives they do not tolerate falls very well, so you need to try to prevent them.
To prevent logical damage, it is additionally necessary to perform defragmentation of partitions from time to time, as well as their optimization.
By following these tips, you will significantly reduce the load on the hard drive and increase its durability.
Black screen when booting Windows 10
Some windows users 10 complain about a black screen instead of the usual splash screen during the boot process. Most often, this problem plagues those who installed Windows 10 by updating more old version OS.
How cunning virus developers are! As soon as Microsoft releases another patch to the system, and anti-virus companies add an addition to the signature database, a new attack appears. What is happening is a typical eternal "dispute" between armor and a projectile, but everyone earns as a result. The only disadvantaged party is the user. He is no stranger to the consequences - stolen logins and passwords, overwritten data beyond recovery, lost system performance, and so on. Fortunately, there are certain rules that allow you to avoid the fact of infection in principle. Well, if the trouble did happen, all that remains is to restore the system to work using the usual methods.
One of the last "squeaks" of the viral fashion of recent years - displayed after loading Windows black screen. In the current version (Windows Seven), the problem is that after a successful initial boot stage, and then the user authorization process, a black screen appears instead of the desktop and menu with shortcuts. The cause of the problem is incorrect entries in the registry keys responsible for loading the shell. The problem has several options, and they differ significantly. For example, if you get a black screen after booting Windows 7 (or in a previous and still popular system, you can do the following.
The first is to install the Black Screen Fix program. An indispensable condition for the effectiveness of this program is the removal of malicious software even before you run Black Screen Fix. For this purpose, the Drweb Cure IT utility is recommended, which has a huge anti-virus database. You can run it from a USB flash drive by pressing "Control, Alt, Divit".
The second, perhaps the surest way is to restore the system through the built-in service. It should be noted that in Windows 7 the procedure is greatly simplified Just press F8 almost after the detection procedure hard drives - you can't go wrong! In this menu, select the startup recovery mode. Load into it by pressing the "Enter" button and select the first or second item. When you choose "Startup Restore", you save a lot of time, choosing the second item "System Restore", you get a guaranteed result. After completing this procedure in the seven, the problem "after Windows boots - black screen" will be a thing of the past. Now be more careful in your actions - use account, limited rights, and install a good antivirus.
"But what if the system is not 7, but XP?" - asks the conservative reader, who stubbornly does not want to demolish the beloved system, which completely suits him, and install the "seven". Unfortunately, this also happens after booting into Windows XP. Black screen and that's it! Then you have to use the registry editor. Well, before that, thoroughly clean the system using the already mentioned Drweb Cure IT. Well, we press the coveted combination "Control, Alt, Divit" and we get the "Task Manager" window. Then, through the file menu, select a new task by typing regedit and now the main system administration tool is launched.
You need to go to HKLM and select the SOFTWARE bush. From here you should choose Microsoft and WindowsNT. Now we are looking for the Winlogon subsection in the Current Version folder, without it the system would not boot even to the authorization window. Check the value of the Shell parameter. It should be strictly explorer, without various add-ons. After all, the essence of the problem lies in the incorrectly loaded malware, it is from here that the roots of the problem "after loading Windows - black screen" grow. It will also be useful to check the Userinit value, which is also critical for loading. That's right - userinit.exe.
It should be noted that this is not all possible options, which the insidious "infection" suggests. The task manager can also be disabled. Then the method with zeroing the parameters to the correct values \u200b\u200bis unlikely to work. We'll have to go a little different way. Run on F8 with support command line and, having loaded, we give the regedit command. We consistently go through CureIT and follow the above recommendations, and then reboot. Black Screen after Windows Boot Problem Solved! If you are enough advanced user PC, it is recommended to use Zaitsev's Anti-Virus along with these programs, which allows you to both remove malware and automatically return the correct values \u200b\u200bto the registry parameters.
You turn on the computer, watch how the Windows 7 boot starts slowly, the desktop should appear just about, but instead of it your eyes opened ... "Malevich's black square". No wallpaper, no desktop icons - just a white arrow cursor, and even then not always. What is the reason for the black screen at startup in Windows 7? How to solve a problem?
Causes of black screens of death when loading Windows 7
- Failure to install system updates, drivers and programs - because of this, pirated copies of Windows are more likely to suffer.
- Viral infection - most likely malware I tried to replace the system files with myself, but for some reason could not and instead broke the boot.
- Damage to startup-critical files or registry keys responsible for it.
- Video subsystem problems, including a 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), hard disk surface defects, and even such exotic reasons as system treatment with one well-known antivirus.
Ways to solve the problem
In the simplest cases, if the cause was a minor failure, rolling back the system to the last good configuration will help. Last Known Good Configuration is the state of Windows at the time of the previous successful start. To return to this state, launch the Advanced Boot Options menu. To do this, quickly press the F8 key several times before starting the system.
The following list will open before you:
Select the indicated item from it and press Enter. If the computer starts up normally, the problem is solved.
Launching File Explorer Manually
It happens that a failure of the graphical shell leads to a problem, when the file responsible for this is not damaged, but only its launch is violated. The task manager will help to solve the problem. Press Ctrl + Alt + Delete or Alt + Ctrl + Shift to call it. Go to the Applications tab in the Manager window 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 Explorer.exe launch key in the registry - the Windows shell, which creates the user environment we are used to - the desktop, folders, and so on.
Start 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 it has. It should be "Explorer.exe", but you probably have something extraneous there.
Right-click on "Shell" and select "Modify".
In the "Change string parameter" box, write a new value. What - you already know.
Next, open the exact same section (Winlogon) in the HKEY_CURRENT_USER branch - the 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 this is an obvious malware. You can do it by hand or using antivirus software. The second option is preferable as it may not be the only malicious file on your machine.
System restore from safe mode
If neither one nor the second method helped, most likely there was a more serious failure. You can try to deal with it from safe mode. To load it, also press F8 several times before windows startbut now select "Safe Mode" from the menu.
Here we have the opportunity to return the state of Windows to the date before the problem. And the application "System Restore" will help with this. Expand "Start" - "Programs" - "Accessories" - "System Tools". Select "System Restore".
To confirm your choice, click "Finish" and wait for the restoration procedure to complete.
It will not be superfluous to additionally check system files for integrity using the console windows utilities - sfc.exe. To do this, open "Start", enter in search string "cmd" and run command prompt as administrator.
Enter "sfc / scannow" into the console window, press Enter and wait for the scan to complete. Sometimes the system asks for a disk with a distribution kit to restore files, but more often everything that is needed is restored from storage on the hard disk.
To find out if the video card or video driver was the cause of the failure, run the system configuration utility msconfig (just like you ran cmd through the search bar in Start).
Reboot to normal mode. If Windows can start, the problem is with the video subsystem. First, update the video card driver, check for overheating gPU and, if possible, test the operation of the computer with another, obviously working video card.
Using the recovery environment
If the previous option did not help, or in safe mode you also see a black screen, there is a chance to fix the failure through the recovery environment. It also has the ability to launch a system rollback and check files for integrity, but there are also special options: boot recovery and windows recovery from a saved image.
To get into the recovery environment, select from the F8 menu (the key you pressed before starting the boot) "Computer troubleshooting."
Follow the instructions to 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 keys, and in case of violation will restore.
The second item from the top is the launch of the "System Restore" application, which we met at the stage of solving the problem from Safe Mode. It is useful in cases where no checkpoints can be found in safe mode. It happens that points exist and are created, but the system does not notice them. And here, in the recovery environment, there are no obstacles to this.
The function works in the same way as in safe or normal modes, so we will not consider it.
The next item is to restore Windows to a working state from archival 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, let's move on. We have another tool, the command line. With its help, we can open Explorer and manually restore the system registry.
Every 10 windows days 7 saves copies of the registry files in a separate folder. We can take them and transfer them to where the current, used registry is located. If the failure is related to its damage, the problem will be solved.
Open a command prompt and run notepad (who doesn't know - this is done with the "notepad" command). Click "File" and then "Open." Navigate through 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 "Files of 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 extension .OLD to them.
Close the explorer. That's all. Restart your computer and try to boot Windows 7 normally. Let's hope you can do it.
Sometimes, Microsoft OS users face a problem when after booting Windows only black screen and cursor mouse. The symptom is quite well-known - it cannot start system process "Explorer.exe". There may be several reasons: a virus or vice versa - antivirus (Avast), problems with the hard disk, etc. Quite often fix black screen on startup can be done in a minute without any third-party utilities.
As 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 cover two popular reasons why when Windows boots up, a black screen and a cursor are visible instead of the 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 recovers very easy.
Avast is the culprit behind the black screen on Windows startup.
So after Windows booted, but on the screen there is only a black "Malevich square" on which the "abstract cockroach" - the mouse cursor is running, do the following:
- 1. Press the world famous combination of buttons " Ctrl + Alt + Del"And select" Start Task Manager "from the list.
- 2. After the Task Manager window appears, find in the list of processes " avast"(The" 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 the Avast antivirus is installed. Find the file "AvastUI" in it and run it (double click or "Enter"). The main antivirus window should open.
- 4. Go to the top tab " Safety", Select" Antivirus", And among the menu items that appear, click on" Behavior screen».
- 5. Open display 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 - The next boot of the operating system should be successful. It is possible that the problem has already been solved by Avast's developers, but the process of adding the program to the "trusted" ones can still come in handy. Moreover, it is not known how the antivirus will react to the upcoming release Windows 10.
In the event that you use another antivirus, then try to find in its settings a similar item to create 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 at boot Shouldn't bother you anymore. The defender, who responds so inadequately to popular programs, is likely to receive a corresponding update in the next few days (or maybe hours). It is possible that it will be received automatically if there is an Internet connection and a configured function to update the antivirus via the Internet. Otherwise, it is recommended to download the updated version from the official website.
Not always mistakes and similar situations when Windows starts caused by antivirus. There may be hardware problems. The review was recently published. But further we will consider the solution when, in the current situation ( only the mouse cursor is on the screen) Incorrect Windows registry settings are to blame.
What if only a black screen and mouse are visible when Windows starts? We correct the system registry.
The first step is exactly the same as in the case of antivirus: you need to open , use it to run registry editor and check / fix a couple of Windows registry values.
- 1. In a state black screen press the world-famous combination of buttons "Ctrl + Alt + Del" and select "Start Task Manager" from the list.
- 2. After the Task Manager window appears in the top menu "File" select "New task (Run) ...". The Create New Task window will appear. In the "Open" field, enter the command "" (without quotes). The Registry Editor window will open.
- 3. In left side windows go to the section (something like "folders" in explorer) with the name " 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. In the right part of the window you will see a list of parameters. Find the parameter named " 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. If the "Shell" parameter is absent at all, then create itby selecting "New" - "String parameter" from the context menu of the "Logon" section. Specify the name of the new parameter ("Shell") and then double-click to set the value ("explorer.exe").
- 5. As in point 3, go to the section " HKEY_CURRENT_USER \\ Software \\ Microsoft \\ Windows NT \\ CurrentVersion \\ Winlogon". Here is the right side should not contain the "Shell" parameter. If there is one, then remove it via the context menu or by pressing the "Delete" button on the keyboard.
The above two methods will help you restore Windows if at startup black screen and mouse cursor... Changing the "Shell" parameter often indicates that a computer has been infected by a virus. It is quite possible that it has already been neutralized by the installed antivirus, but traces of its activity could have remained in the system (change to "Shell").
When Windows 7 boots up, a black screen and a mouse cursor occurs due to a lot of factors, each of which sometimes defies logical explanation. When loading Windows 7, a black screen and the mouse cursor can come suddenly, while the user may not even suspect what a mess is going on in the file system. Before moving on to action, I recommend delving into the root of the problem and understanding where this ailment comes from.
So, when Windows 7 boots up, a black screen and a mouse cursor appears, most often, because of We are all people and we are not all sinless, we cling to viruses left and right, as a result of which, Windows is gradually being cut off. At first, the operating system may work slowly, then it will generally start giving out a black screen. Viruses, as soon as they enter the Windows kernel, are immediately thrown into system folders and start to create ridiculous chaos there. It is easy to guess that the only sure thing to do is to install antivirus. By the way, not every antivirus will be useful.
In my memory there were quite civilized computers with a similar problem. When booting Windows 7 black screen and mouse cursor and nothing could be done about it. In some cases, Windows still boots, however, only a couple of hours after turning on. The real cause of this disaster was the world famous Avast is an antivirus that blocks vital system files, in particular Explorer.exe.
Actually, the file presented above is main reason the fact that when Windows 7 boots up, a black screen and a mouse cursor haunt the user. Explorer.exe is responsible for the explorer and everything else that should be displayed on the desktop. This file may "die" or not start for various reasons - viruses, conflict with other programs, as well as due to the "natural aging" of the operating system, as a result of which the user loses the right to run this file.
There is also the use of pirated Windows 7. In such cases, when Windows 7 boots, a black screen and a mouse cursor appear after the next system update. The system can download a special update that verifies the authenticity of Windows. Of course, if you sit on pirate Windows, then this can happen to you.
The likelihood of problems with the video card drivers is extremely small, but it is still worth mentioning. An unpleasant formula "outdated video card + too new drivers" can lead to a black screen with a mouse cursor. Here you can also include the use of firewood, downloaded from nowhere, developed by someone who is not clear.
The most unpleasant thing is faulty hardware. Here it is already difficult to determine exactly where the epicenter of the problem is located. This may be the failure of RAM dies, problems with hard disk, and occasionally malfunctions of the north and south bridges.
Black screen with mouse cursor - first steps.
Let's start with the simplest. Before turning on the computer, remove all USB drives from it - flash drives, hard drives, Wi-Fi or 3G adapters. Often, the system refuses to start due to incomprehensible conflicts between the hardware and the software level. For the future, I recommend
We go through safe mode.
We turn on the computer, we see a black screen and a mouse cursor, and when Windows 7 boots up, wait 5-10 minutes and if nothing happens, then proceed to the action. As we said in the previous paragraph, the root cause of the black screen and the working cursor is problems with the Explorer.exe file. First of all, press the key combination Ctrl + Alt + Del, after which the Windows Task Manager should appear over the dark background. I think you already have an idea of \u200b\u200bthis controller and know how to work with it, but still - repetition, mother teaching.
The first tab displays all applications currently running, in our case, this tab should be empty. Go to Processes and try to find a workflow called Explorer.exe. With 100% working condition of Windows, it will look like this:
Well, if the mouse cursor appears on the background of a black screen when loading Windows 7, then this process will not be in the list. On many forums, you can stumble upon "thieves" advice from experienced programmers about this problem, for example, rewrite a piece of the kernel in C ++. We don't need this!
The most effective option is to start Windows from Safe Mode. By the way, get used to this bun, since most actions with a faulty system are solved only by this method. So, we restart the computer and click on the F8 key. You will see this picture.
Once you get to this menu, select "Safe Mode with Command Prompt". After that, the system will boot up with the familiar CMD utility.
Actually, the Windows console is a beautiful creation that often comes to the rescue. We type in the line Explorer.exe, as in the example above. This way, we will be able to overcome the black screen with the mouse cursor when Windows 7 starts up and start the system in working order. True, subsequent launches in normal mode will again be accompanied by a dark screen and a single cursor. What do we do next?
The antivirus war.
Let's start with antivirus. If you use Avast, then we need to uninstall it, or reconfigure it. First of all, go to the antivirus settings, then "Protection active" - \u200b\u200b"File system screen" - "Settings" - "Exceptions". As we said, Avast can block the Explorer.exe file, so we need to add it to the list of exclusions. It will look like this:
Then we reboot and see what happens. If the black screen and mouse cursor did not disappear when Windows 7 started, then read on.
OS activation.
Let's go back to the question of activation. If after starting Safe Mode, you see such a picture, then this is our case.
This problem is solved quite simply - you need to download "Crack". This is a kind of key that activates the pirate. Real Windows users shouldn't be afraid of that.
Debugging through the registry.
Let's suppose that the black screen and mouse cursor when starting Windows 7 arose due to the hooliganism of viruses in the registry. Therefore, we will try to solve the problem manually. By the way, this method can be used both in normal and in safe mode.
Open the task manager and click "New task", after which such a field for input will appear.
We enter the regedit command, after which the registry editor will open in front of us. Follow a similar thread as in the next picture.
Find the Shell file, double click open its settings. Remove the set value and enter explorer.exe.
We reboot. If the problem still persists, we will continue brainstorming.
System Restore.
Feature presented - universal remedy from all the problems. Let's take the path of least resistance, run through safe mode, then Start - all programs - standard - utility -
The first window does not carry anything useful, we click "Next".
Now we have to select the point to which the rollback will be performed. This is a kind of return of the system to a working state, if you like, you can make an analogy with time travel, may Marty McFly be with you. We select the desired point and go forward.
Read the contents of this window and click "Finish".
The last warning will pop up, with which you must agree.
The recovery itself will start during Windows reboot. As soon as the system starts up, you will see a message like this:
So, Windows is fully operational on this. In most cases, the problem of a black screen with the mouse cursor when starting Windows 7 is solved in this way.
Rollback drivers and left software.
Once again, let's remember about bad drivers that should be eliminated. In general, automatic driver rollback is performed during system restore, although you can turn this process much faster. So, enter through Safe Mode, then open Device Manager (Computer - System Properties - Device Manager).
Find our video card, and then right-click to open the properties.
Go to the driver tab and select rollback. Then, after rebooting, the video card will work with the previous firewood. If the next launch goes without a black screen, then the problem is solved. If not, then uninstall the driver and try again.
Dead iron.
Finally, let's return to the most unpleasant. Let's say you've completely reinstalled Windows, but it's no good. Now I propose to dig deeper into the gland. Try turning on the computer by combining the operative dies. Also, you can check rAM programmatically... Read about how to do this in the article "" in point number 5.
In other cases, you should check the performance of the rest of the hardware - processor, video card, hard drive. This can be done by a banal change of iron - old to donor. In the case of a hard drive, it can be checked with the Victoria 4.47b program. You can read how to do this in the 4th paragraph of the article "Why the computer freezes", the link to which is located above, and also watch the video below.
Conclusion.
That's all, actually. Remember that the most effective method is reinstall Windows , but if even this does not help, it is necessary to look for the source of problems in system unit... Happy work!
