Black desktop when loading windows 7. Black screen when you turn on the computer. Reset BIOS settings

Today we will look at:

It is not difficult to imagine what a novice user experiences when looking at a black screen that seems to be loading the operating system. In most cases, in this situation, all the user can do is aimlessly move the mouse cursor over a blank screen. You will be pleasantly surprised, dear friend, but even a primary school student can solve the problem of “Black screen when starting Windows 7”, guided by the material of the presented article.

A few words about the "black" reason

As practice shows, this kind of trouble mainly occurs as a result of improper shutdown of the computer (also includes interruptions in the centralized power grid), or when the user completely ignores the issues of preventive maintenance of the electronics entrusted to him. Anyway file structure hard drive the computer is damaged, and this in turn leads to banal software failures.

Often, the so-called "Malevich's Black Square Effect" manifests itself as a result of a viral infection. Malicious program code destroys the integrity of system files, the result is that after the OS starts, the desktop disappears, that is, the user is greeted by emptiness, and nothing more.

And finally, the third “black” reason is a technical malfunction of the video card or monitor, or a corny missing video signal due to mechanical damage to the connecting cables.

Where to begin?

First of all, you need to find out if everything is in order with the device for displaying the image on the screen, that is, check the performance of the video card. Moreover, not always visually observable information at the initial stage of loading is an indisputable confirmation that everything is in order with the graphics adapter - this is a delusion.

However, if during the OS boot process you observe an incomprehensible flicker or other "visual artifacts" - it's time to sound the alarm. If possible, switch to another video scheme, that is, turn off the discrete video card and use the integrated video chip.

The second stage of diagnostics: check if everything is in order with the connecting cables, maybe the wire is broken somewhere (bend slightly, twist, in general, move). It is possible that your pet has clearly played with a hanging wire (bite marks, exposed winding, etc.).

It makes sense to disable everything peripherals from system block or a laptop. Perhaps a “black conflict” is the result, so to speak, of crashed drivers of some external device, for example, a printer, a removable drive, etc.

Software fault diagnosis and recovery

There are quite a few methods to restore the former "beauty of visualization", but let's focus on the most basic of them. Remove the disk from the optical drive, if one is present there, and unplug the USB flash drive, if you have not already done so.

If all the attributes of the desktop appear on the screen, you are in luck. Now you can safely proceed to the next stage of system recovery.

In the search box of the Start menu, type "recovery".
In the window that opens, click on the link of the same name.
Next, select a workable rollback point and start the OS recovery process.

If the aforementioned service has been disabled on your PC and there is simply no copy for rollback, then try resorting to the method described below.

Checking the hard drive for errors

As a result of intensive use of the hard drive, systematic violation of operating rules (incorrect on / off system) or ignoring the issues of optimization and maintenance of the information storage device (HDD), the occurrence of various system errors it's just a matter of time. By the way, the obsolescence of the disk surface and the mechanical parts of the hard drive also lead to software failures and hardware conflicts.

So, press the key combination "Win + R".
In the Run service console, type "cmd".
Next, in the command window, write - chkdsk with: / f

To the request for a reboot, we affirmatively agree.

Virus infection and editing the Windows OS registry

It is not uncommon for a malicious program to make changes to the registry of the operating system. Therefore, you need to make sure that the correct values \u200b\u200bare written in the branch responsible (for the blackness of the screen).

It is also worth checking another registry key:

Well, the last thing to do is to scan the entire HDD on the subject. It is likely that the remnants of the digital infection through certain time will make themselves known again.

In conclusion

We hope that the recommendations of the presented article have helped you. However, do not lose vigilance. Install an authoritative antivirus program and don't forget to regularly perform preventive maintenance on your computer. The stability of your system!

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 such a failure and what to do in this situation is the main topic of this article.

Problems when booting the system

The problem has a wide range of factors that provoke it.

In addition, a black screen can also be displayed in different ways, such as with or without a cursor.

Let's take a closer look at the main causes of failure:

Booting Windows in Safe Mode

Initially, you should try to secure boot systems.

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

Shut down your computer to terminate all processes causing the black screen.

Then launch it again, 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 this is the case, then after booting into safe mode, you will see a warning on the screen that you are using an unofficial version that should be licensed.

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

Hardware malfunctions

Monitor and system unit

The black screen may be caused by hardware problems.

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

Lack of normal contact between the monitor's network cable and the outlet

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

If such a problem arose 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 a strong mechanical impact, such as a fall or impact.

In this case, the deformation of the monitor will be visible to the naked eye: colored stripes will be traced, areas with dead pixels, scratches, etc. .

On a computer, a black screen when logging in can be caused by a 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 fastening in the motherboard slot, as well as the stability of the supplied voltage and cooling (if it is not passive).

Checking the operation of video card drivers

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

To do this, open « Task Manager» using a key combination Ctrl+Shift+Esc.

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

The latter sometimes mistakenly blocks various system files.

To return the computer to a normal working state, you will need to complete some antivirus processes.

Using the button combination 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 launched again. To avoid repetition, you should create certain exceptions for the antivirus application.

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

Go to the program settings window and select the active protection item.

Then go to the file system screen tab 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 to the input field - "C:\Windows\explorer.exe" and "C:\Windows\immersiveControlPanel\systemSettings.exe". Then click on the OK button.

In order for the explorer.exe process to start, you need to use the menu "Run" and enter the name of the process in a special window.

After pressing the OK button, you need to restart the computer.

With the transition to a new operating system with a black screen when loading Windows 10, it is difficult to surprise anyone, which is the most curious, so many different reasons can lead to this that when you turn off the computer, you don’t know what will happen when you turn it on. Let's try to understand each situation together and solve it.

Video card drivers

You installed the updates, everything seems to have gone well and here it is the first restart and a black screen after loading Windows 10, how to understand that the reason is in the video? If you hear a loading sound, but no image, then this is obvious. It happens that the desktop does not start, the black screen and the cursor, and sometimes only the cursor is visible, similar incidents happen even after an energy-saving mode or sleep. Before starting to fight with the drivers, I would also like to note that this happens in the case of two connected monitors - try disabling the additional one, if it does not help, let's turn it off at random in the system. We do the following:

Try to enter the password by visual memory and press enter, by the way, the default language is Russian in dozens.
Next, press + [p], here it will be enough for you to press 1 time -

If we saw what is happening, it would look like this - see screenshot

If this does not help, and you have a black screen instead of the desktop, then download the drivers from the official website of the developer, try to boot into safe mode, for this we press F8, and already there we do diagnostics and rearrange the driver.

System restore required

Your computer seems to have booted up, a screen appeared with a windows 10 welcome screen and a password field, and after a black screen, in this case we do this:

This may be the result of a virus attack, do not forget about routine antivirus checks.

Quick start system

Experience shows that when windows boot 10 a black screen hangs for a long time for owners of AMD_Radeon video cards, and the reason is banal - the system interferes quick start, we need to disable it in order to bring Windows back to life.

We will perform the "blind" method, the most important thing is that you hear the sound of the OS loading, let's start. We have two such options.

1 option

We need to restart the system, we intuitively and accurately perform it step by step:

Press "Backspace" 3 times - this will remove the splash screen and accidentally entered password characters;
;
If there is a password at the entrance, switch the layout (depending on the language of the password) and press [enter];
Gently slowly, press + [r], switch to the English layout, we wrote above that the default language in Windows 10 is Russian
Enter the command without quotes "shutdown / r"
Click a couple of times on

After that, as a rule, the screen shows an image, if windows 10 does not load and still a black screen, then move on.

Option 2

The methods are similar, but some of the commands are executed differently, let's get started:

Press "Backspace" at least 3 times;
On "Tab" - press 5 times in a row! So we hope to stumble upon the on and off buttons.
1 time ;
Up Arrow button and [enter] again;
A restart should happen.

And again on the laptop a black screen when starting windows 10, what should I do? Let's try the radical 3rd method.

3rd fallback ... but I'm afraid that they will throw it, nevertheless .... hold the computer / laptop shutdown button until it is completely turned off.

If at least 1 of the 3 methods helped you, and the system booted up fully with a picture, then there is a conflict between the vidyuhi drivers and the fast start of Windows, the latter must be disabled.

Disable fast startup

Having tested the “blind” method, we still won, but this is not for long, the problem may return, so we follow the “Control Panel” by clicking RMB on “Start”, then:

"Hardware and Sound"
"Power"
On the left, select "What the power buttons do"
At the top "Change options that are currently unavailable"
Scroll down and in the "Shutdown options" uncheck "Turn on fast startup (recommended)"

Save and try restart! After, everything should be stable.

Integrated adapter

Black screen in windows 10, during installation or after, an unsuccessful update or installation of drivers on the video card may have occurred. If there are two video cards, of which the discrete one works, there is a chance to defeat all the buggies. We connect a monitor to the second video output and try to correct the system operation, either by restoring the system from the last known good configuration, or using the built-in restore function.

We demolish firewood to the vidyuhu from, but we also need to get there by touch.

1 option

Above we wrote how to get to the "Diagnostics" menu, then

Press the down arrow key three times
Press the down arrow key twice
Double-click the left arrow key
If the launch succeeds, we will see a screen with a choice of safe mode.

Take a look at the screenshot

Option 2

Using the command line, you need to enter a command, and you can get into it using one of the methods described above. Switch to English and enter the following accurately:

"bcdedit /set (default) safeboot network" → "Enter"
After 3 seconds, enter the following command "shutdown / r"
If everything was successful, a window will appear asking you to download Windows.

Low Resolution Safe Mode

Considering how many examples were given, we hope that it still came to loading Windows in safe mode and now we need to reduce the load from the vidyuhi by choosing a low resolution, try the keys or .

Here again, you can choose either from the control panel - described above, or uninstall the driver on the video card, and try to load Windows - the image in this case should appear, since Windows will load the standard ones.

Sometimes, when booting 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 consider what are the most effective ways to fix this problem in Windows 7.

Most often, a black screen appears after the Windows welcome window has been opened. In the vast majority of cases, this problem is caused by an incorrectly installed Windows update, when some kind of failure occurred during the installation. This entails the impossibility of launching the explorer.exe system application ( « Windows Explorer» ), which is responsible for displaying the graphical shell of the OS. Therefore, instead of a picture, you see just a black screen. But in some cases, the problem can be caused by other reasons:

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

We'll look into ways to fix this issue.

Method 1: Restoring the OS from under "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 healthy state. This method can be used when the device has a restore point that was formed before the black screen problem.

First of all, you need to go to "Safe mode". To do this, restart the computer and when it is turned on again after the beep, hold down the button F8.

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

But in most cases it doesn't help. Then, in the boot type shell, select the option that involves activation "Safe Mode" with the support "Command line". Next click Enter.

The system will start, but only a window will open "Command line". Drive into it:
After entering, press Enter.

The entered command activates "Conductor" and the graphical shell of the system will start to be displayed. 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".

Open folder "Standard".

Enter the directory "Service".

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

The start shell of the standard OS resuscitation tool is activated, where you should click "Further".

Then a window is launched where you should select the point to which the rollback will be performed. We recommend that you use the most recent version, but one that must have been created before the black screen issue occurred. To expand your choice, check the box "Show others...". After highlighting the name of the optimal point, press "Further".

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

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

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: Restoring OS files

But there are times when the OS files are so badly damaged that the system does not boot even in "Safe Mode". It is also impossible to exclude such an option that you simply may not have the necessary recovery point on your PC. Then you should perform a more complex procedure for resuscitating the computer.

When starting the PC, move to the boot type selection window, as demonstrated in the previous method. But this time, from the presented items, choose "Troubleshooting..." and press Enter.

The Recovery Environment window opens. Choose from the list of tools "Command line".

The interface opens "Command line". In it, enter the following expression:
Be sure to click Enter.

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

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

The Load Hive window opens. Navigate in it to the section of the disk on which your operating system is located. Next, go to the directories sequentially Windows, "System32" and "config". If, for example, your OS is on drive C, then the full path to navigate to should be:
C:\Windows\system32\config

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

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

In the directory that opens, select the folder setup. In the right part of the window, among the elements that appear, find the parameter "cmd line" and click on it.

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

Now go to the parameter properties window "SetupType" by clicking on the relevant item.

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

Then return to the window. "Registry Editor" to the section that was previously connected, and select it.

Click "File" and choose from the dropdown list "Unload bush...".

A dialog box will open where you need to confirm the decision by clicking "Yes".

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

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

The computer will be checked for the integrity of the file structure. If violations are detected, the procedure for restoring the corresponding element is automatically activated.
After the restore is complete, enter the following command:
shutdown /r /t0

Click Enter.

The computer will restart and turn on normally. It is important to bear in mind, however, that if system files were damaged, which caused the black screen, then, quite possibly, the root cause of this could be viral infection PC. Therefore, immediately after restoring the computer's performance, check it with an anti-virus utility (not a standard anti-virus). For example, you can use .

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

The main reason for the appearance of a black screen when booting the system in Windows 7 is an incorrectly installed update. This problem is "treated" by rolling back the OS to a previously created point or by performing a file recovery procedure. More radical actions also involve reinstalling the system or replacing computer hardware.

The appearance of a black screen when you turn on a Windows computer on board is a very common phenomenon. There are quite a few reasons for this behavior of the system, as well as methods for eliminating such problems. But in order to choose the most suitable solution, first you need to figure out what exactly such failures can be associated with.

Why does a black screen appear when I turn on the computer instead of loading the operating system?

Before considering the main reasons for this phenomenon, it is worth paying attention to the state of the screen itself. The most common variations are:

black screen with inscriptions when turning on the computer;
a blank black screen when turning on the PC or rebooting;
black screen with cursor.

As for the reasons for this phenomenon, in the first case, you should pay attention to what kind of messages are displayed on the screen. For example, when it is reported that the boot is from a non-system disk, this means that the system is accessing an optical disk or flash drive that is currently attached to the computer, but there are no bootloader files on them. Just remove them (from the drive or port) and restart.

If the message indicates that there is no operating system or, even worse, a hard drive, then the problem is much deeper, and cardinal methods will have to be applied to restore the computer to working order, which will be discussed separately.

Finally, one of the reasons could be a corrupted or missing graphics adapter driver. If anyone does not know, after the initial check of the system components in the BIOS, when the computer is transferred to the system bootloader, the video card is first activated to display the image on the screen. If there are problems with it, the operating system will not be able to start.

Black screen when turning on the computer: what to do first?

But it is not all that bad. It may well be that the reason is not software failures or damage to the computer hardware. No matter how it sounds, after turning on the computer, a black screen may appear only because the monitor is dimmed or in standby mode (while the LED is blinking). Another situation may be related to damage to the power cable or connection to the video card. It needs to be checked, and at the same time to see if the contacts are oxidized. However, physical breakdowns and minor malfunctions are usually not called the main reasons, so let's move on to troubleshooting at the software level.

Fast system recovery

Let's start with the situation when, when you turn on the computer, the black screen does not “hang” on the monitor all the time, but disappears after a certain period of time. In this case, the loading of the operating system can start as usual. If the start is impossible, you must reboot again and use access to the start boot menu, which is called by pressing the F8 key (for systems higher than the seventh version, the F8 combination with the Shift key sometimes works, but it is better to use it first command line and return the normal boot method by setting the bcdedit /set (current) bootmenupolicy legacy command to be executed, followed by a system reboot).

If, when you turn on the computer, the black screen is replaced by calling the boot menu without problems, you can use the standard last known good configuration boot item, which is analogous to the most common system restore from an OS state checkpoint with workable parameters.

Standard system rollback

If, for some reason, the previous method does not suit the user, for example, because he needs to restore the system from another point, but the standard boot is impossible, in such a situation, starting in safe mode is suitable.

After the download is complete, you should enter the system recovery section through the "Control Panel" and perform the standard rollback procedure by selecting the appropriate point from the list, after displaying all temporary components.

Actions when booting from removable media

If none of the rollback options work, and when you turn on the computer, the black screen appears again, you can use some of the system tools available when booting from an installation or recovery disk (flash drive), which must be set as the first priority in the settings of the primary BIOS input / output system downloads.

Note: If UEFI is used as the primary system, the flash drive must be pre-formatted to FAT32 because file system NTFS is not accepted for UEFI boot.

After starting, it is advisable to immediately go to the command console (Shift + F10) and check the system components by entering the sfc /scannow command.

The process can take quite a long time, so you have to be patient. Just in case, you can also use the disk check, supplementing the main chkdsk command with related attributes, which you can find out by calling the help information (chkdsk /?).

Note: if the execution of the above commands does not give any result, and when you turn on the computer, the black screen appears again, you can boot from removable media again and run the online recovery commands DISM.exe /Online /Cleanup-image /Scanhealth and DISM.exe / in the console Online /Cleanup-image /Restorehealth.

Problems with the video card driver

The above methods are universal and help restore system performance in 99 percent of cases out of a hundred, but only if this is due specifically to software failures of the OS itself. But most often the problem is in the graphics accelerator driver, since a black screen when you turn on a computer with Windows 7 or with any other system may appear for this very reason.

To reinstall or update it, you will need to at least start in safe mode, after which you will need to call the standard Task Manager (devmgmt.msc) and try to update the driver using the operating system.

If this does not help (most likely it will), it makes sense to use utilities like DriverPack Solution Online 17 or driver booster, which can update the control software without user intervention. The only condition for a correct update is the presence of an uninterrupted Internet connection (when choosing the download mode in the initial menu, you should use safe mode with download network drivers).

Update problems

Finally, a black screen when you turn on the computer can also appear when installing critical system updates. This is most often seen on Windows 7, for which the updates themselves are full of bugs, and for Windows 10 computers that have AMD processors(the recent failure of AMD-based systems after the update of the “dozens” around the world is a clear confirmation of this). To fix problems, in safe mode, you need to use either the "Update Center" or the Programs and Features section, and then remove the failed packages one by one, checking the system's health, then set up a manual search and exclude the failed components from the mandatory installation list).

Note: to simplify the actions with the removal of update packages, it is recommended to use programs like iObit Uninstaller, in which such procedures are carried out to the fullest extent.

Restarting the Explorer Service

Another reason for a black screen to appear when you turn on your computer is a failure in the Explorer service (not to be confused with "Explorer"). To start in safe mode, you should call the "Task Manager" and complete it forcibly. After that, through the file menu, you need to create a new task, enter the name of the desired service in the line and confirm the command by pressing the "OK" button.

The nuances of power settings

Sometimes this behavior of the system may be due to incorrect configuration of the current power scheme. This applies to the parameters of the so-called quick start.

Activation of this mode can be done through the sections of button actions and changing parameters that are currently unavailable. After installing the necessary options, you should reboot and see how the system will react to the measures taken.

Disabling permanent reactivation of Windows

Finally, many experts cite problems associated with the file responsible for activating the system as one of the reasons, when its operation can loop. To correct the situation in the root folder of the system for 64-bit OS or in the System32 directory for 32-bit systems, you need to find the Windows Activation Technologies directory, then sequentially go to the Tasks and Microsoft subfolders, and then delete the Windows directory with all the contents in the last directory and perform a system restart.

Note: in order not to deal with deleting a folder, you can simply stop the service of the same name in the corresponding section and set the disabled startup type for it and disable it in automatically loaded processes.

Brief summary

That, in fact, is all about the appearance of a black screen instead of the expected loading of the operating system. As you can see, the methods for correcting such a failure are not particularly difficult. In most cases, unless the main problem is related to failures in the operating system due to damage to its components, it is enough to check the graphics adapter driver and, if necessary, update or reinstall it. In all other cases, restore normal Windows work you can either through safe mode or when booting from removable media, which looks more preferable, since the tools present on it do not directly depend on the behavior of the OS installed on the computer's hard drive.

However, if we are talking about a hard drive, for example, about situations when it starts to “crumble”, so as not to change it immediately and be able to transfer important information to other media, you can use a unique and one-of-a-kind recovery program called HDD Regenerator, which is claimed to be able to remagnetize the surface of the disk, thus avoiding data loss or recovering them.
