Windows startup black screen: what to do if your computer won't turn on. The computer does not turn on black screen The screen turns black

The appearance of a black screen when loading the operating system may at least cause confusion for the user. What is the cause of the malfunction when a black screen appears when the computer is turned on? IN this case there seems to be a launch, but the image itself does not appear (nothing is shown on the monitor). In some cases, even the cursor is missing, there is no signal, and it is required to take measures to quickly correct the situation.

Then how to remove a black screen on a work computer when the image does not appear on it when turned on? First of all, you need to understand what exactly is the cause of the malfunction. The reasons for such a breakdown include technical and software, but in 50% of cases the user is to blame due to his inattention, and sometimes simple lack of knowledge.

An example from life. A motherboard with an integrated video card was purchased. To increase the performance in games, an additional external video card was purchased. When assembling the PC, everything was connected correctly and worked perfectly. Further, after cleaning or transferring the system unit, the wires were disconnected and reconnected incorrectly. The wire from the monitor instead of the external video card turned out to be connected to the built-in one (VGA or DVI connectors are the same on all devices). Naturally, the PC was configured to work with an external video card and it simply would not start with the built-in one. Inattention or ignorance? Draw your own conclusions.

The technical reasons why the monitor does not turn on, the cursor is not visible and there are no standard inscriptions at boot are as follows:

The PC is switched to the mode for working with an external monitor (in this case, the absence of a signal is relevant for laptops).
Loop malfunction (also a problem that is relevant only for laptops).
Malfunction of the video card.
The cable was connected to the wrong connector.
The cable that connects system unit and the monitor - again a black screen appears after loading.
The monitor is powered off, so it won't start, nothing appears on the screen, not even the cursor.
Malfunction of the monitor.

Software malfunctions that lead to the fact that the monitor does not turn on when the computer starts up, a black screen appears, include:

The presence of a viral malware that prevents the computer from performing work. It is because of her that a black screen is shown on the monitor.
Inappropriate screen resolution.
The update rate on the video card of the computer is incorrect.
Incorrect operation of the operating system loader or drivers.

Solving technical problems

To solve the technical problems of how to remove the black screen, it would be wise to use the following course of action:

You want to make sure that Personal Computer switched on. For this, the presence of working light signals, the sound of a working cooler is checked. The cursor does not appear.
It is checked whether the connection cables to the system unit, the power cables to the monitor, and whether the button on the monitor is enabled.
If a black screen appears when you turn on the computer, then a check is made where the cable is connected to the socket. If necessary, you can reconnect the cable.
If your computer uses an integrated and external video card, then you need to check which of these devices the monitor is connected to. You may need to switch the cord to a different connector.

Laptops almost always have an output to connect to an external monitor. If, when starting the laptop, you hear the sound of coolers working, which is accompanied by a black screen on the computer, then it is likely that the mode of operation with external monitors was launched on purpose or by accident. On the keyboard, you should find the function keys for controlling the operation of the external monitor and try to turn on the internal display.

The F7 key turns on / off the internal screen, and the F8 key controls the combination of output to the internal / external laptop monitor. They must be pressed simultaneously with function key, which is usually denoted by Fn.

Different operating modes are switched by successive pressing of the following key combination: Fn and F8. Considering the question of how to remove the black screen, you can try this method if the laptop's internal monitor has been accidentally turned off.

If you are sure that the black screen with the cursor was caused precisely by technical problems, and the above steps did not help you solve the issue, there is still no signal, then you should contact the repair company or service center... In this case, you are unlikely to be able to fix the problem yourself.

Solving software glitch problems

If you encounter a black screen after turning on your computer due to malware or software glitch, it is recommended that you follow these steps:

Try booting your operating system in safe mode. If you succeed in this, then you need to continue to follow the steps below. If not, then your only option would be to download operating system using external media.
When the operating system is booted into safe mode, it is worth checking the refresh rate and screen resolution settings. If the computer monitor has not turned on before, then they need to be replaced with the correct ones.
Then the video card drivers are updated. Although Safe Mode is used, it should be done using Device Manager.
If the monitor turned on for a long time on the computer, then you need to start antivirus software and thoroughly scan your PC for the possibility of being infected with malicious software. Ruthlessly destroy all files that pose a threat.
After completing all the steps, the computer should be rebooted.

When the monitor turns on, turns off immediately, or a black screen appears after upgrading to a new monitor, do the following:

The old monitor is connected to the computer.
The minimum screen resolution and refresh rate are set to 60 Hz. This is done in special utility video card driver or in the display properties.
The computer connects to a new monitor. Now you need to adjust the screen resolution and frequency for the new display.

There are times when, with the computer in full technical health, the above steps do not help solve the question of what to do if the computer has a black screen. IN this option you can contact the specialists. Some malware are detected only manually, while antivirus programs will be useless.

Unusual reasons

What to do if the black screen is not caused by technical or by software? A black screen can appear due to the banal carelessness of users, which sometimes reaches the point of absurdity. Before starting to search for complex causes of the problem, it is worth checking your attentiveness:

Could you deliberately or accidentally reduce the brightness of the monitor to a minimum? Then you can't say that the monitor turned on for 2 seconds and goes out, but the image itself is absent.
Are the metal parts of the PC "short-circuiting"? Static electricity can enter computer cases. The device will start shutting down suddenly for the user, even when booting up. This problem is often caused by touching the body of elements conducting current, or a large accumulation of dust inside the system unit.
It is worth listening to the sound of the cooler. Is the fan running or unusual sounds? Often, due to a malfunction in the cooling system, a sudden shutdown of the PC occurs. To avoid this problem, the computer must be kept clean. It should not be leaned against cabinets, walls, or near batteries.

The problem of a black screen appearing when you turn on the computer is solved by fixing a specific error. If you check the case for static voltage, turn up brightness or replace the cooler, the problem can be solved.

In any case, the appearance of a black screen should not lead the user to panic. In a fit of fear or bewilderment, you can only aggravate the situation. You cannot knock on the system unit and the monitor, this will not solve the problem, or it may even completely disable the computer. It is still not recommended to disassemble the system unit yourself and switch wires in it, if you have no experience in repairing it, and you do not know how the computer works.

Today I would like to discuss with you the reasons why the computer turns on, but there are no images on the monitor. In other words, "there is a black screen".

The black screen when you turn on the computer is not always the same. It can be divided into 3 parts:

Black screen due to the fact that the power connectors for the monitor are poorly tucked, both into the outlet and into the monitor itself, or the monitor is poorly connected with a cable to the computer.
Black screen right after you hit the power button. That is, the monitor turned on, but there are no initial motherboard splash screens, inscriptions and numbers just before the operating system boots. This is a hardware problem. Most often, in this case, the sign "No signal" hangs. It is also possible that the computer starts beeping. The signals can be different. Below, we will analyze in more detail how to restore your computer to work.
The computer turns on as usual, there is an initial screen saver for the motherboard, (not all computers should have one, so do not be alarmed) inscriptions, numbers are running, and after all this stuff, the usual boot of the system begins. After that, a black screen just hangs, and sometimes a black screen with a cursor. It is possible that This problem most likely software level and it is quite easy to fix, except when hard disk the end has come and the computer simply cannot read information from it.

Reasons for the appearance of a black screen.

Below I will write absolutely all the reasons due to which a black screen pops up when you turn on the computer, and then we will take a closer look at each of them.

Dust cleaning is required.
Defective video cable (VGA, HDMI, DVI) or monitor.
The video card is defective.
Problem program or driver.
A problem with hard disk.
Other hardware problems.

Now, let's look at each of these reasons in order. Go!

Dust cleaning is required.

The computer turns on, and instead of the usual boot, a black screen hangs? This is a fairly common problem. In 80% of cases, this is due to the accumulation of a large number of dust. In this situation, you need to pull out all the computer components from their connectors, remove the cooler and processor heatsink, and then thoroughly blow them and the system unit itself from dust using a special can of compressed air. (sold in any self-respecting computer store) You can find out how to do this in the article "" Also, I would advise you on a processor, video card and other chips, (where it is required) and also (if necessary).

Defective video cable (VGA, DVI, HDMI) or monitor.

Perhaps the reason that the computer turns on and a black screen hangs on the monitor is a faulty video cable.

It is of three types:

In order to test this theory, you need to connect the system unit using this cable not to the monitor, but to the TV. Or just borrow a known working cable from a friend.

By the way, the computer monitor is checked in the same way.

The video card is defective.

This cause also causes a black screen when the computer is turned on.

The fastest and most effective way to test a video card for performance is to substitute another video card in its place. If an image appears when you turn on the computer, go to the store for a new video card.

Problem program or driver.

This reason, due to which the computer turns on and then a black screen appears, is fundamentally different from all the above and below described. The fact is that the problem is most likely at the software level. Remember what you did the last time the computer worked? Perhaps you downloaded something, installed something or uninstalled it. A black screen with a cursor most often occurs when the video card driver is damaged. In order to correct this misunderstanding, you should enter Safe Mode. To do this, restart your computer and as soon as it starts to turn on again, press the F8 key. The launch menu will open in front of you. It can look differently. (it depends on which system is on your computer)

So this menu looks like on Windows 7.

After the computer has booted into safe mode, you need to do a system restore. An article on how to do it correctly lies

If the computer does not boot into safe mode, then there are 2 options:

The damage to the system is too global (in this case, and should be, but before doing this, you should check HDD for errors and correct them. (if possible) It is also possible that after the correction errors - system will start as usual.)
Hard drive problem (read the article below)

Hard drive problem.

A black screen on the computer monitor may also indicate that something is wrong with the hard drive. To check and try to fix the malfunctions, the Victoria4.46b program is used. The video below describes in great detail and shows how the program works. I will only add that in order to recover bad sectors (errors), you will need to put the switch in the Remap position before starting the test.

By the way, the video shows how to check the hard drive while the operating system is working. But Windows does not work for us. In order to check the HDD without booting the system, we need to write Victoria program 4.46b to disk in a special way (the Internet is full of instructions on how to do this) and will not boot from hard disk as we usually do, but from the disk where Victoria is located. How to boot from disk read

Other hardware problems.

If you, in turn, tried all the methods described in this article and nothing helped you, then most likely there was a serious hardware failure. You should take the computer to a service center for diagnostics. Experts will check everything and tell you which part should be replaced.

This concludes my article. I hope she helped you remove the black screen from your computer monitor. Thank you for attention! Good luck!

Sometimes you can observe a rather strange and frightening phenomenon - you, as usual, turn on the computer, but instead of loading Windows, a black screen appears when you turn on the computer. Often, it displays a list of all possible boot variations, from which you should select the one you want.

The appearance of a black monitor is already a direct signal of the presence of errors that can have a very negative impact on the functioning of your device. However, you should not immediately panic and reinstall the system.

As a rule, such a malfunction can be solved independently, without significant effort. Therefore, further we will consider what to do if you are faced with this trouble.

Black screen when turning on the computer - why does it appear?

First of all, you should figure out what can provoke such a phenomenon. The reasons can be very varied. However, one of the most common is that the computer was shut down incorrectly. It is worth noting that the user is not always to blame for this. A sudden power outage is enough to cause a black screen.

Computer infection with a virus

We should not forget about the enemy of every user - computer viruses... Some can cause serious disruptions to the entire system and provoke all sorts of errors. Therefore, you need to try to use the most reliable antivirus tools and not be lazy to constantly carry out a comprehensive scan of your device for viruses.

Perhaps the contacts have moved away?

If the computer turns on, as usual, and you hear a single squeak from the system unit, informing about the successful boot and health of the computer, nothing is displayed on the monitor, you need to check the monitor itself and its connection.

Make sure the cable is firmly connected to the system unit. Often, when moving a computer from one room to another, it can be unreliable to connect all the components. Check the cables for damage. It makes sense to try turning on the monitor without connecting it to the computer. If there are signs of life coming from it and a message is displayed stating that there is no signal, then there is no problem with it.

Now let's consider the situation when, after turning on the computer, Windows does not boot, but only a black screen appears with possible options downloads.

System or program crash

Such a black screen is already a signal of the presence of operating system problems. Having looked carefully, you can see in it a list of various download options, from which you have to choose the right one. First of all, you need to make sure that the system can be turned on in safe mode. After the computer has turned on, periodically click on the F8 key, thus opening a menu with additional boot variations. After that, using the arrows on the keyboard, select the item called "Safe Mode", and then click "Enter".

Safe Mode will come to the rescue in case of problems concerning the system. It can be especially useful if the gadget has been infected with programs that harm and interfere with the normal functioning of the system. In this mode, you can start the wizard and get rid of many problems.

There are several different options that you can use to launch different types safe mode.

The first on the list is the standard "Safe Mode", which is often used. A minimum of various applications and services are launched here. However, this mode does not imply access to the Internet.
Next on the list is Safe Mode with Boot network drivers". Here you can already use the Internet. In addition, there is "Safe Mode with Command Line Support". Here you can use various commands to control the system. Often administrators give preference to this item.

So, you have selected the required mode and you have downloaded from it. If, as usual, the desktop appeared, there is a possibility that it appeared due to a certain malfunction in the programs. If a program was recently installed, after which, on subsequent system starts, the above screen appeared, the problem may lie in it. Here the best solution will be a simple removal of such a program or driver to eliminate the error.

When the download is carried out in the required mode, I advise you to conduct a comprehensive scan of the device for viruses using the appropriate utilities. In addition, it does not hurt to check the registry for the presence of dangerous codes.

Nothing appears on the desktop - no shortcuts

Sometimes you may find that, although the black screen no longer appears, nothing is displayed on the desktop - no icons, not the Start panel. However, this can be corrected simply by following the steps described below.

Press the key combination Ctrl, Shift, and Esc at the same time. A window with a task manager will appear, in which you have to go to the first tab, as shown in the figure. Then you should click on the item "New task", and then print the command "regedit" in a new window.

Navigate to the registry directory using the following path:

In this directory we find a parameter called "Shell". It should contain only one value - "explorer.exe". If other values are found there, they must be deleted, and the parameter is saved with only one, the aforementioned value.

Blocking the system and the task manager

Sometimes a rather unpleasant situation occurs when the task manager is blocked and cannot be opened, and the safe mode does not start. However, here you can easily fix everything.

There is such a thing as sticking the Shift button. Five times in a row, at small intervals, by clicking on this button, the sticky buttons window will open. Follow the link at the bottom of the window.

In the next window, in upper corner on the right, there will be a search box. It should print "Task Manager".

Then you need to go to the item called "System".

On the left side of the window, select the section called "system protection".

After that, all that remains is to perform a system recovery using the previously created checkpoints.

Malfunction of the video adapter or "crooked" driver

Sometimes the reason for the black screen can lie in the malfunction of the drivers for the video card, which is why all sorts of problems with the monitor arise, including its blackness. Therefore, this option also deserves attention.

A fake copy of Windows

If you become the owner of pirated Windows after performing certain updates, a black screen may appear with a message stating that the version is not genuine. If you are faced with such a problem, the best solution is to use a licensing system.

Internal damage

If suddenly none of the above methods helped to find the problem of the black monitor, and after checking you made sure that there are no viruses, you should inspect all the details directly in the system unit.

It is necessary to check that each of the cables and wires located both outside and inside the system unit is intact and not damaged in any way. In addition, it is useful to make sure that there is no damage to the connectors and ports.

Before starting the inspection, you must turn off the power, and only then dismantle the cover of the system unit. All elements of the motherboard should be examined and checked for even the smallest damage on them. Since the system unit is constantly clogged with dust, you should clean everything as carefully as possible.

It also doesn't hurt to check the wires that connect the various parts inside your computer. They must certainly be completely intact, without damage to the insulation. Make sure that their connection is not taut.

Sometimes it may happen that one of the available modules random access memory has broken. You should extract all modules and test each one separately. However, it often happens that by cleaning the planks and reinstalling them, everything works again. When the computer has not been used for a long time, the CMOS battery may discharge. It can be found at motherboard, and, in this situation, it can also be replaced with a new one.

Perhaps these are all the main steps that an ordinary user can do, without contacting specialists, in the event of a black monitor. Since the described malfunctions are quite common, they are the most likely cause of this phenomenon.

Speaking on behalf of a computer repair technician, it is worth noting that when repairing an unfamiliar device, it is difficult to guess in advance how it was handled. Therefore, the cause of the problem may be the most unexpected.

The two cases described below may well receive the award for the most extraordinary reasons for a computer failure. However, thanks to them, you can clearly understand how every little thing can cause serious malfunctions in the operation of such a complex device.

In each of them, the reason lay in the adhesion and clogging of computer elements with a foreign substance, or, in simple words, dirt. In the first case, it ended up on the motherboard tracks, and in the second - on the video card. This provoked the appearance of a dark screen when turning on the computer.

It is worth noting that the term "dirt" means any substances or small objects not provided for by the PC design. As a rule, this is dust, but there are also quite strange situations. It was difficult to determine where this dirt came from, but after carefully cleaning such a substance with a cloth soaked in alcohol, the computer turned on without any problems and began to work as usual, and still functions perfectly.

In the second situation, we encountered such a phenomenon when we purchased a dozen used video cards for terminal buyers. After the acquisition, they began to be checked, and it turned out that three of them were out of order. Immediately, a study of the non-working samples began, and something rather suspicious was noticed in the corner of the board.

In the following picture, you can take a closer look at it:

Here you can see the dirt adhering directly to the board tracks. Taking into account the previous situation, we decided to repeat the procedure for cleaning the faulty video card. After all, it is likely that it is precisely because of this incomprehensible substance that the performance of the computer is disrupted, and its full load was replaced by a black screen.

Immediately, the familiar manipulations were performed to cleanse the plaque, using alcohol and a cloth. Each lane has been carefully cleaned. The main thing here is to be extremely careful so that the tiny elements of the board that protrude are not damaged in any way. As a result, everything looks like this:

After drying the card and reinstalling it on the computer, a real miracle happened - everything worked fine. Therefore, for most, at first glance, difficult problems, fairly easy solutions are found.

Summarize

So, this article described the most popular reasons why a black screen appears when you turn on the computer, as well as the main ways to fix this problem. If you still have unanswered questions, you can safely ask them in the comments, and we will certainly help you!

Black screen when booting Windows- a problem that sooner or later many users face, but not everyone knows how to fix it. What do you need to do? First you need to study possible reasons... There are many of them and they are different. They can be both technical and software, and sometimes the problem lies in the usual carelessness.

Problem with wires and / or connectors

A typical situation is problems with cables, connectors and power buttons.

Checking the Power Supply to the Monitor

If you have desktop computer, then check the power supply to the display first... Some users get so used to working on a laptop that when they switch to a desktop, they do not notice the obvious. The power button on the monitor is just off. It is no coincidence that the instructions of IBM specialists, developed for the first PCs, assumed that the very first point was checking the power supply.
The second common reason for a sudden black screen when turned on is insufficient power cable contact. In practice, there were often cases when the cable plug was loosely held in the socket, and turned off when the display was moved or the active participation of household members, including furry ones. In the office, poor cable-to-monitor contact is often caused by the cleaning staff, who touch the wires while cleaning.

Checking the contact between the video card and the monitor

The second reason for the situation when the coolers work, but the computer does not turn on and shows a black screen is a problem with the cable between the video card and the display. There can be two options:

The cable is out of the socket.
The cable is not connected to the main output of the video card.

With the first case, everything is clear. Just check the integrity of the cable itself and the reliability of its fastening in the connectors. But with the second case it is worth explaining. Inspect back panel computer.

If there are two connectors for connecting the monitor cable, then we are dealing with one of the following situations:

In either case, there are two options for connecting the cable. Turn off the computer, switch the wire to another connector and turn on the computer again.

Perhaps someone just switched the cable to a different socket by mistake. The modern HDMI connector is not equipped with screws, like the old VGA, and you can accidentally pull it out of the socket, and then plug it into the wrong socket or insert it not completely.

After restarting your computer, the screen is black again? Perhaps you have a technical problem (more details below).

Remember that whenever you switch the video cable, it is better to turn off the power to the computer and monitor.

"External Monitor"

A laptop almost always has an output for connecting an external monitor. Therefore, if, when you turn on the laptop, you hear the sound of coolers, but the screen is black, then it is likely that someone switched it to work with an external monitor. Locate the external monitor function keys on the keyboard and try turning on the internal display. Here's what they look like on an ASUS laptop:

The F7 key turns off / on the internal screen, and F8 controls the combination of output to the external / internal laptop monitor. They should be pressed in conjunction with the function key, usually denoted Fn.

This is how the choice of operating modes with an external monitor looks like in Windows 8 and 10.

Switch different modes by sequentially pressing the Fn and F8 key combination for the keyboard shown above ASUS laptop... So you can accidentally turn off the laptop's internal monitor and get a black screen when turned on.

Software malfunctions

System bootloader failure

A black screen and a cursor on it after loading a laptop or computer may indicate a failure in the operation of the operating system loader or one of the drivers. If the system startup options menu appears, try booting into Safe Mode. And if not, then there is only one way out. How to make a bootable flash drive is described.

Incorrect refresh rate or too high resolution

The second common problem with a black screen when booting Windows may be the incorrectly set refresh rate on the video card. The fact is that old CRT monitors operate at a high screen refresh rate, up to 100 Hz and higher. And modern LCDs can only support 50-60 Hz. This is due to design feature such monitors.

If you got a black screen exactly when switching from an old monitor to a new one, then you need to do the following.

For the same reasons, you can get a black screen on a laptop connected to an external monitor. Try adjusting the frequency and resolution for the external display as shown in the picture above.

Technical difficulites

What if the black screen when you turn on the computer to win by the means described in this article did not work. Perhaps the reason lies in a malfunction of parts of your PC.

If you are not a repair specialist computer technology, we recommend contacting the service for professional support!

The video card is out of order

With such a malfunction, the laptop or PC fan works, but it does not start and we see a black screen on the screen. According to POST standard we should hear one long and two or three short beeps from the speaker(built-in speaker). The indicated sound indication is typical for AWARD BIOS installed in many mainstream laptops and computers.

POST is a BIOS self-test system. We recommend reading the article about.

Just make sure that the speaker is present and connected to the board. In some modern computers manufacturers do without it, replacing them with LEDs on the motherboard and even small ones digital indicators... But the latter can only be found in expensive motherboards for overclockers.

The monitor is out of order

A malfunction of the display itself manifests itself in exactly the same way, only without sound signals... The computer does not turn on, although the coolers are working, and the screen is black. As a rule, you should see in this case other signs of desktop activity: the drive LED is blinking, for example. You can check whether the display is broken by connecting it to another PC or connecting the computer itself to another display or TV. Many video cards today support HDMI, which is found on modern TVs.

If the laptop does not turn on and shows a black screen, then this may mean a malfunction of the cable connecting the system board and the display. You can check this by connecting the laptop to an external monitor.... If there is an image, then the video subsystem is working, but the display or its loop is not.

The black screen that appears when the operating system starts up is called one of the most difficult errors in its work. At the moment when the user sees problems with booting the system, the first thought arises about reinstalling it. But this is not the only measure that can be taken when Windows 7 does not boot. The black screen can be removed in other ways.

Windows 7 black screen reasons

First of all, you need to understand why this failure occurred. Then you can fight it more effectively. There may be several reasons:

failure of the video card drivers - in this case, nothing will be displayed on the black screen: no symbols, no cursor;
problems after update software or the system itself;
the presence of files involved in loading the system, working incorrectly;
damage to the OS by viruses;
defects in computer hardware.

The first thing to check when your computer does not start is whether you are connected to it peripherals: flash drives, smartphones and others. It is best to disable them and restart your computer - in some cases this will help get rid of the black screen.

Rollback using system restore points

If you regularly, when it worked stably, then the black screen when loading W indows 7 can be removed with their help. To do this, you need to follow the instructions:

Restart your computer and press the F button before loading the OS 8. You should see a screen with startup options.
From this screen, use the arrow keys to position the cursor on Last Known Good Configuration.
Hit Enter. If after that you see the usual operating system boot screen, then the problem is solved.

This method will help if the crash occurred after virus attack or due to a system update. Select the system image to boot by the date it was created.

Debug mode

The creators of operating systems have included special startup recovery tools in the shell. If you do not start Windows 7, the black screen can be removed according to the instructions:

When the computer boots up, press F 8. Select the "Troubleshoot computer problems" option from the list.
After pressing Enter, the Recovery Wizard will start. Working with it is simple and intuitive. First, select "Launch Repair".
After that, the system will automatically scan its files and restore them using the entries in the memory.

After the recovery, the computer will restart and you should be able to see your desktop again. Debug mode helps a lot if the computer stops starting after a power outage.

System Restore Using Safe Mode

When you press the F 8 key in the menu, you can choose another boot option: "Safe Mode with Command Prompt". This option also helps to remove the black screen when Windows startup 7.With this tool you need to work like this:

Press F 8 while starting the computer, after the start screen with technical information... Select the boot option in Safe Mode with Command Prompt.
The system will start with a Command Prompt window. You need to enter the explorer.exe command into it and press Enter.
This command activates Explorer. You will see the familiar design of the operating system, but it's too early to rejoice. You need to go to the Start menu to standard programs... Then expand the "System Tools" directory and click on the "System Restore" line.
You will see a wizard window that revives the system. Click on the "Next" button and select a point to restore.
Now you just have to confirm your choice with the "Finish" button. In the pop-up window, click Yes.

The computer will begin the rollback operation, during which it will be rebooted. After that black Windows screen 7 will disappear.

Comprehensive computer recovery Windows 7

If you do not have a previously created restore point or the previous options did not work, then you need to follow a different instruction. It will work even if system files are too damaged, and the operating shell does not load even in Safe Mode... If a black screen appears on your Windows 7 and there are no recovery points, do this:

When the system boots, press F 8, select the "Troubleshoot" option from the list. Press Enter to load the utility.
You will see a list of available tools, from which you need to select the option "".
A Command Line window will appear on the screen. In it, you must enter the regedit command to load the Registry Editor interface. After entering, press Enter.
The peculiarity of the running editor is that the entries in it refer to the recovery environment. Therefore, you must first select HKEY_LOCAL_MACHINE. Then click on the "File" button and select the "Load Hive" command.
Enter C: \ Windows \ system32 \ config in the address bar or go to Windows folders, system 32, config. In the folder that opens, find the SYSTEM file and click on the "Open" button.
You will see a window for loading the partition hive. Enter in it any name from a pair of Latin letters and 2-3 numbers. Click on the "Ok" button.
In the HKEY _LOCAL _MACHINE folder, a section titled with the characters you entered appears. Open it up.
Select the Setup folder and on the right side of the window find the CmdLine option. Click on it and in the window that opens, enter cmd .exe. Click on the "Ok" button.
Now, on the right side of the Registry Editor window, click on the SetupType parameter. In the window for making changes, enter "2" and click on the "OK" button.
