When starting the computer, a black screen with inscriptions. Black screen on a laptop or computer: we are looking for the cause and troubleshooting. Enabling Fast Startup

The occurrence of the so-called "black screen" during loading operating system confuses the user at the very least. What can cause a malfunction when, when you turn on the computer, there is a black screen, although there seems to be a start, but the image does not appear (the monitor does not show anything) and sometimes there is not even a signal, a cursor, and what needs to be done to quickly correct the situation and continue working with the PC ?

In order to solve the problem of a "black screen" on your computer when it turns on and the image does not appear, first of all it is worth figuring out what is the cause of the malfunction. The reasons can be of various kinds: software or technical.

TO technical problems, when there is no signal and the cursor is not visible, the standard inscriptions do not appear during loading, primarily the following:

monitor malfunction;
the monitor is powered off - that's why it does not turn on, nothing appears - including the cursor;
cable connecting the monitor and system unit departs - again, not;
the cable is connected to the wrong socket;
video card malfunction;
cable malfunction (but this is true for laptops);
The PC is switched to the mode of operation with an external monitor (but, again, in this case, the lack of a signal is relevant for laptops).

The list of software malfunctions that can lead to a “black screen” after startup and a situation where there is no signal is a little narrower:

incorrect operation of the operating system loader or drivers;
inappropriate refresh rate on your PC graphics card;
inappropriate screen resolution;
viral malware that prevents the computer from doing its job and nothing appears precisely because of it.

In order to solve the technical plan problem, it would be wise to use the following action plan:

Make sure the computer is turned on (you can hear the sound of the cooler running, the lights are working, but the image, the cursor does not appear).
Check if the button on the monitor is turned on and if the power cables and connections to the system unit are connected to it.
Carefully check the places where the cable connects to the socket, reconnect the cables if necessary.
If your computer has both an external and an integrated video card, then check which one the monitor is connected to (but you may need to switch the cord to a different connector).
When working with a laptop, if then there is no signal and no cursor, try switching the external monitor control button (usually this can be done by pressing the Fn and F7 or F8 keys).

If you are sure that it was technical problems that caused the black screen problem, but the steps described above did not help you and still there is no signal and cursor, contact service center or a repair company, as you are unlikely to be able to fix the problem yourself.

Faced with a "black screen" due to a software failure or malware, we recommend that you follow the instructions:

Try booting the OS in safe mode, if you succeed, then continue on the points below, but if not, then the only way out is to boot the OS from external media.
After booting the operating system in safe mode, check the screen resolution and refresh rate settings, and change them if necessary.
After updating the drivers for the video card, even if the mode is safe, but this can be done through the "Device Manager".
After that, run your antivirus program and thoroughly scan your computer for malware infections. All files that pose a threat, ruthlessly destroy.
Well, then restart your computer.

It happens that with the complete technical serviceability of the PC, the steps described above do not help. In this case, it is recommended to contact programming specialists at a service center or a special company. It is possible to detect some malicious programs only manually, then anti-virus programs are useless.

Unusual Reasons

In addition to technical and software reasons, a banal user inattention, sometimes reaching the point of absurdity, can also cause a “black screen” and a situation where there is no signal after turning on the PC. Before looking for complex causes of a problem, check your attentiveness:

could you have accidentally (or deliberately) lowered the brightness of the monitor to a minimum? True, then you cannot say that there is no signal, but there will be no image;
Does it “short” the metal parts of the computer? Sometimes it happens that static electricity hits the PC case, then it can turn off suddenly for you, including during boot. Often, a significant accumulation of dust inside the system unit or touching current-conducting elements to the case leads to such a problem.
listen to the sound of the cooler, isn't it time to do something there - do you hear any unusual sounds? Is the fan working? Sometimes, a cooling system failure also causes the computer to shut down suddenly. To avoid such a nuisance, keep your computer clean, do not lean it with a cooler against walls and cabinets, do not place it near the batteries.

You can solve the problem of a "black screen" in such cases after correcting a specific error, that is, add brightness, check the computer case for the passage of static voltage, or replace a faulty cooler.

In any case, the appearance of a “black screen” should not lead you to panic, otherwise, in a fit of bewilderment or fright, you can aggravate the situation. In no case should you knock on either the monitor or the system unit - this will not solve your problem, but it can completely disable the PC. It is also not recommended to disassemble the system unit and switch the wires in it yourself if you are not familiar with the principle of the PC and do not have experience in fixing it.

Prevention

To prevent the occurrence of a “black screen”, problems with the cursor and monitor, you must use a reliable antivirus program and update virus databases in time, avoid dubious files and links, as well as monitor the technical integrity of the computer and always be attentive to your own actions and what is happening after them.

Help of the wizard

If you didn’t succeed in eliminating the “black screen” and displaying the cursor and image on the screen, and you turned to specialists for help, then remember that you need not only describe the problem, but also the last steps that directly or indirectly could affect the operation of the computer. Your description of the latest manipulations will help the specialist to identify the cause of the problem and fix it faster. Be sure to tell the technician if there are any unusual sounds or smells coming from the computer.

At present, a considerable number Windows users 7 met with a new scourge. This user-friendly operating system, capable of automatic updates, is quickly gaining popularity. But while it really is not all as smooth as we would like. And such a misfortune as 7 is becoming more and more common. Often the problem begins to appear after one of automatic updates. Although this version of events is unofficial, there is still a certain assumption on the part of Microsoft.

However, Microsoft themselves persistently deny this fact and are still conducting research, slowly issuing conclusions. And, most importantly, to somehow help users with solving the problem. However, a security hole allows malware make changes to the system. Or rather - in the holy of holies, the registry. After such an intervention, the very infamous Windows boot 7.

The reason that causes a black screen when starting Windows 7

Independent experts have already conducted their own examination. In its course, it turned out that the main trouble lies in some features of the storage of registry data that new system. The vulnerability refers to the Shell value. With some changes, it is not processed correctly, which ultimately causes a frightening black screen when loading Windows 7. Wallpaper, taskbar, sidebars - nothing loads. In rare cases, you can only see the explorer window, and then if it is not minimized. Otherwise, the latter will also sink into obscurity.

Solution

How to fix the black screen when loading Windows 7? There are several ways to solve this annoying problem. Unfortunately, most of them turned out to be ineffective. The most popular option, which has successfully proven itself and has already helped more than a dozen users, is as follows. The combination of three keys (Shift + Ctrl + Esc) should be called. It selects the execute command new task(file -> execute). After these steps, a window should open in which you need to enter regedit command.

This command calls and allows you to view We need the HKEY_LOCAL_MACHINE->SOFTWARE->Microsoft->WindowsNT->CurrentVersion->Winlogon branch. Its contents will appear on the right, where it remains to find the notorious Shell key and double-click on it with the left mouse button. Everything that should be in the window that opens after this is in the single value of "explorer.exe". Perhaps there will be values with other names. All of them can (and even should) be removed.

If no extra values were found, the Shell key itself must be deleted and recreated. It's easy to do. In the area where the key was located, you need to right-click and open the corresponding menu. It will have an option to create. We need to create a string parameter with the same name as the remote key (Shell).

Black screen when loading windows xp

This phenomenon is also not uncommon. A black screen here may occur after installing the third package Windows updates(Service Pack 3). Or the first one, which they try to install over Service Pack 2. The incompatibility of some elements of the system causes similar problems when loading. Appearance The downloaded image is the same as in the case of problems on Windows 7: a completely black screen without any icons, launcher and background. Only the explorer icon remains.

The most common cause of a blank black screen is the presence of dangerous viruses in the system. Elimination in this case is associated with ridding the computer of this scourge. For the solution, a small Prevx patch is used, which takes only about 50 KB. The convenience lies in the fact that when you start the program itself performs all the necessary actions. Sometimes helps with boot disk.

Another good utility is called Malwarebytes' Anti-Malware. It is suitable for owners of any operating room. Windows systems and check their system for viruses. After all, even the best and most reliable antivirus program does not guarantee 100% protection. Therefore, it does not hurt to check the contents of the computer with a specialized utility for detecting Trojan viruses.

If, when you turn on the computer, a black screen fills the entire display space, then the first step is to check all the contacts. Make sure the monitor is plugged in and the indicator light is on. Check the cable connecting the video card and the monitor. If a black screen appears when you turn on the laptop, go straight to the next stage of diagnostics - checking the software and hardware status of the device.

Error message

If a black screen appears with inscriptions, then you need to rewrite or remember the information that the computer is trying to transmit. Usually, a specific reason for the problem is indicated - for example, "Bootmgr is missing". The computer told you what the problem is, you just have to see what to do in a particular situation.

A black (blue) screen with white letters also appears when you run the Check Disk program. If the system was shut down abnormally, then when the computer is turned on, an error check will be launched.

Do not interrupt the operation - wait for it to finish, then the next time you start the system, it will no longer turn on. If you cancel the check, then a screen with white letters will appear every time you start the computer.

Possible reasons

Before we begin to understand why, after turning on Windows instead of the usual boot, you see a black screen and a cursor, let's see the possible causes of this problem:

Installing an unlicensed copy of the system.
Damage system files or registry.
Virus infection.
Problems with video card drivers.
Hardware malfunctions.

If the black screen does not appear immediately, but when you start Windows, try loading the Last Known Good Configuration. Windows 7 users need:

Restart your computer (laptop).
At startup, press F8 until the menu appears.
Choose to load Last Known Good Configuration.

On Windows 8, this convenient option, unfortunately, is missing. Therefore, you will have to check the system through safe mode (if the last known good configuration on Windows 7 did not help, also use safe mode).

Working in safe mode

Start Safe Boot Mode network drivers using the F8 key or installation media with Windows 8. If the system starts correctly, then you need to check that there is no inscription in the corner that you are using a copy that is not genuine.

If there is an inscription, then you can remove the black screen using the correct Windows activation or shopping license key. Also, try performing a System Restore by rolling back to a date when the black screen didn't stop you from working.

Be sure to check your video card drivers:

Open device manager.
Find your video adapter.
Open the properties and go to the "Driver" section.
Select Rollback.

If rolling back your drivers doesn't help, try doing the opposite - update software video cards.

Press Win+R and run "dxdiag".
On the Display tab, look at the device name and driver version.
Search the Internet for software for your video card model and update the drivers.

Another point is to check your computer for viruses. Use antivirus and cleaning utilities (Dr. Web CureIt, Kaspersky Virus Removal Tool) to increase scanning efficiency. Remove any malicious applications before trying to boot the system normally again.

Hardware failures

Hardware failures are harder to deal with. It’s good if there is no signal on the screen - most likely, the cable connecting the monitor and the video card just came off. If a screen without anything appears immediately after starting the computer, and there is no way to boot into safe mode, then you have encountered a hardware malfunction.

Inspect all ports and external cables - they should be intact.
Remove the cover of the system unit and carefully inspect the system components, as well as the cables. Pay special attention to the video card - it should not have any damage or dirt.
Remove all modules one by one random access memory, wipe the contacts, then reinstall the trims.
Clean the system unit (laptop) from dust.

A squeak from the motherboard speaker will help determine a hardware malfunction. Find a troubleshooting chart on the Internet that allows you to sound signals BIOS to determine the nature of the error.

If the computer does not beep, then the system itself may be damaged. motherboard. This is probably the most annoying problem you can encounter. If you have already done everything possible, and there was no reaction from the computer, then you should contact the service center - home diagnostic methods have been exhausted.

Black screen when loading Windows, what is it? This kind of error strikes fear into a good half of computer users, although it is often possible to solve them without serious manipulations with the PC. There is no reason to panic, but you will have to roll up your sleeves in order to restore the correct operation of Windows.

There are quite a few reasons for this problem, and almost all of them are related to some kind of malfunction in the system.

The most common cause can be called failures in the operation of video drivers, since it is your adapter that is responsible for the correct display of graphic content.

Other common reasons are: the consequences of a virus infection of the system, incorrectly installed drivers or other applications that have damaged the registry, and broken updates of any programs.

The first step is to determine at what stage it occurs: in general, the monitor does not turn on, and the diode indicating its operation lights up in such a way that it is loading. In this case, and these are exceptional situations, you will have to try connecting your monitor to another computer and, if not, take it to a service center. Also, if the system unit is working normally, and the monitor does not react to it at all, including the diode, there is a high probability that the video card will break. Most likely, the black screen becomes after the system boots, in which case you can eliminate mechanical damage to the computer and use the methods for solving the problem, described below.

Launch desktop display

Perhaps everything starts up for you, but there is no service that is responsible for displaying the desktop. To restore correct operation you need:

1.Press the key combination Ctrl + Alt + Del;

4. Enter explorer.exe in the line.

These steps should be enough to display the desktop, but the issue should be resolved completely. How to do it - read on.

How to start the system in safe mode

To perform this task, you should press F8 or Shift + F8 during Windows boot, sometimes the buttons are different. Also, when you are the owner of a system version 8 or higher, you will probably need to start the OS in safe mode installation disk, in the event that you do not reach the loading of the account login window. For Windows 8 and higher, the algorithm for switching to the mode we need looks like this:

1.Insert media with installation version systems;

2.Now at the time of loading, usually right after the Bios window or just at the time of its appearance, press F9;

3. You will see a window with a choice of devices connected to the computer, specify your drive or flash drive;

4. In the window that will be before installation, select "System Restore";

6. Enter the code bcdedit / set (globalsettings) advancedoptions true and press Enter, then click Continue.

After completing these steps, when the computer restarts, you will run desired mode. Best of all, if you have a choice, run the option to download the network drivers. This stage is Starting point for the steps below.

Reinstalling video card drivers

It is highly likely that this item can help you. Removing these drivers is quite simple, since in safe mode only the most necessary functions are launched, which our application does not apply to. Just use the "Programs and Features" item from the control panel of your system. Also, you may want to use a specialized program for this purpose, for example: Driver Sweeper, it is as easy to use as possible.

You don't even have to install video adapter drivers directly from safe mode, try starting Windows in standard format and, if possible, install a working application from there.

Black screen - computer infected with viruses

One of the most common problems of the present time, since a variety of errors can be a manifestation. Relevant both for problems with the registry and for failures in the software part of Windows. The first thing to do with such a problem, you should analyze the entire hard drive, especially system partition and, after detection, add to quarantine or delete the found files. Now, after cleaning the computer, you should return the normal boot of Windows, it is described in more detail:

1.Open the registry editor by pressing Win + R and type regedit;

2.Go to the specified path HKEY_LOCAL_MACHINE-> SOFTWARE-> Microsoft-> Windows NT-> CurrentVersion-> Winlogon;

3. Check the value of the Shell parameter, it should be explorer.exe;

4. Userinit variable, must contain the path C:\Windows\system32\userinit.exe;

5.Save your changes and restart your computer.

Antivirus software conflict

You should not have more than 1 antivirus running at the same time, otherwise the computer will start to lag a lot and can cause all possible consequences of a system failure, including the lack of desktop display. To see if this is so, you can go to the "Control Panel" and find the "Programs and Features" item.

All files are locked from changes and you most likely will not have access to them, even if you get it, the system will not allow you to delete the files, since they are involved in the work. Here, too, you will have to start from safe mode and remove one of the programs.

Not a genuine copy of Windows

After the end of the trial period of using the system, you are given the opportunity to buy a license or use Windows with limited functionality, for example: instead of your desktop splash screen, there will be a black screen and after rebooting, even if you installed a picture, the situation will return to normal. In the standard case, these will be just inconveniences, but sometimes the desktop display is completely blocked, which is a failure. The way out in this case is obvious, you should get a Windows activation key in any way, at your discretion.

How to perform a system restore?

In order to, you should do the following:

1. Right-click on "My Computer" and select "Properties";

3. In the tab of the same name, in the column "System Restore" click the "Recovery" button;

4. Then select one of the points at the time of creation of which the system was working properly and follow the instructions.

Usually, if the failure occurred due to any interference from applications or other system failures, this method will be able to return you to a full-fledged, working Windows.

Good afternoon, we continue to fix emerging bugs in Windows, and today we will try to solve the problem of an empty desktop after a reboot. The problem is that the black screen that appears after loading does not let the user into the system. As a result, as it seems to the user, only a manual restart is required. Invoking the Task Manager with Ctrl+Alt+Del leads to nothing. The maximum that the user finds on the Malevich square is a “live” mouse. An error can accompany the user from download to download, which is frankly annoying. And, most likely, the error lies in wait for the owners of Windows 10, and more often the owners of laptops, so let's start from here. However, the owners of desktops are also not easy, besides, they are deprived of some power-saving features, which are also worth checking out. So, if you already encountered a download error, check out the article.

What's the problem?

Yes, their sea, comrades. Here is a list of the most common reasons.

The problem is often seen in the fact that you have either an integrated video controller from Intel or another discrete video card. Windows does not have time to automatically redirect the video signal to the “correct” output, switching to the second, as it seems to it, monitor out of bewilderment. Yes, she sometimes thinks there are two of them. And she thinks so, including thanks to the mentioned video card. A similar problem has already been described in an article with a similar title. Black windows screen , but in more recent builds, the focus of the question has shifted somewhat. If the problem appeared after connecting a second monitor or TV, disconnect it.
If you notice that the black screen appears exactly after the computer is turned OFF, and not after REBOOT, the reason for this is 100% the fast boot function, coupled with a broken file hiperfi.sys. The first is to disable, the second is to delete. More on this below or in the article.
The next reason is the inhibitory File Explorer. Probably not of their own free will, but because of the newfangled functions and applets that appeared in Windows 10. If you knew what exactly from the settings in the Start panel slows down, you would have thrown it away at the installation stage, otherwise ... I strongly recommend that you read the article right away. And get ready - you have to work in safe mode, where many features are not fully disclosed.
Another one possible reason – bootloader changes Windows entries . Apparently, the system leaves some task for the next session, but cannot do this at the time of loading. After you turn off Windows at the moment the black screen appears, the task is reset and the system boots normally. For the black screen after loading Windows most often lies in wait for the owners of a multiboot system. In my experience, the problem was successfully resolved (or delayed) after. However, as soon as the boot process returned through the Grub bootloader (the second one is Linux), the black screen problem sooner or later returned as well.
I will continue fiction. Who is waiting for how long? Believe me, in fact, a black screen after loading with a cursor on the screen is 80-90% oh-oh-oh-very long system loading. On one of my computers, I waited for a full start after 5-6 minutes. The problem sometimes goes away after installing a good optimizer and defragmenting the disk (if it has an HDD, not a hard drive). If you encounter a problem again, take your time - just make sure that the system does not boot at all (an indirect signal may be the end of the blinking of the boot LED hard drive). But if the system still shows itself, start with autorun as well. I'm not talking about Windo, he won't tell us anything. Take a look at the program Autoruns for Windows from Russinovich. He appears in one of the options.

Black screen after loading: try to skip

Move the mouse until the cursor appears on the screen
click Ctrl + SHIFT + WIN + B
visible changes may not occur on the screen, unless the mouse becomes exactly in the center of the screen. However, now you just need to enter the required password if the login is in account requires registration
if nothing happens, try pressing Enter and re-entering the password. For a while, the cursor will disappear from the screen, which means that Windows is processing the entered registration data. Sometimes the waiting time takes several minutes before Windows fully loads. However, if nothing happens, and the mouse is in place, this is not our case.
If you still cannot enter Windows, use the opportunity to enter Safe mode or repeatedly press before downloading Shift. In general, your task is to get into Windows. It is possible that you will have to turn off the computer several times again with the button.

Black screen after loading: trying to fix

Well, try everything in a row: there are a lot of manipulations ...

Immediate update - this bug is already patched as far as I know
In an open session, we immediately go to the power settings using:

powercfg.cpl

We are looking for a button on the left Power button actions and by clicking on it, go to Settings. If the buttons Shutdown Options unavailable, click the interactive link Change settings that are currently unavailable. Disable Enable Fast Startup and save the changes:

now go to the console Windows (services.msc) and extract one of them called Application readiness, changing to Disabled:

time to check Autorun. We launch Autoruns for Windows on behalf of the administrator and check a few parameters. We are interested in tabs (1) Winlogon, in which we remove extensions, if any (do not delete, just uncheck). These extensions have a lot of dependencies, but are easily hit by all sorts of rubbish:

I have a library in a single copy: splash screen on the background of “Welcome”

(2) Everything- the most useful of the tabs, which will show everything that starts with Windows in all its sections and services: from the scheduler and startup to menu items for additional commands (those that are launched by right-clicking). See:

all sections of autorun are presented here - check them slowly

Looking ahead, I’ll say that in search of a solution to this problem, I simultaneously decided a lot of other things. For example, it was this utility that showed me that my Windows scheduler is simply full of some tasks:

Rubbish was removed manually - the scheduler gave out the location with a bang:

and finally, the reason for the misfortune of many users:

the remnants of the program from the Program Files folder were deleted using

However. Remembering the unsolvable task before Windows startup, just in case, check one more tab of the program (3) Scheduled Tasks. It turned out that the Window Scheduler was hiding something from me, to put it mildly:

I think there's a lot of stuff in there too. Remove slowly one by one and check by rebooting. I guarantee that after these manipulations of “black windows” after a reboot or turning on Windows you will decrease.

Further. Open Task Manager and in the list of Processes check RunOnce(if not, look in the list of services RunOnce.exe). Neither the first nor the second MUST BE running. If you see it, kill the process and stop the service by setting it in the Startup Properties Manually. Rarely, but rolls.
disconnect ALL USB devices while booting
you with Windows themes did you do any manipulations? used programs like UXStyle or StartIsBack? Do not hesitate - your problem has legs growing from here
either the explorer process itself is probably broken File Explorer, or something in its logs prevents it from starting normally. And the only solution in this case is to run the repair utility from cmd on behalf of the administrator sfc/scannow. Checking the integrity of Windows files.
Reboot and check.

The weapon of last resort: reinstalling the video driver.

We are left with the last option. He helps often, you just need to be able to do it. Let's reinstall the video driver. Moreover, the reinstallation is not justified by what you downloaded (or NOT downloaded) latest version- the driver for the next step, in any case, needs to be stocked up. The fact is that reinstalling the driver for any device entails resetting all settings, plans, parameters and services that are associated with it. And there may be “bazhny” or “bazhny” configured - those that cause a black screen after loading. Let me remind you the procedure (the most useful and reliable is described in the article):

loading into Safe mode with network driver support
identify the device: right mouse on the screen => Display settings => Graphics adapter properties

download from the manufacturer's website
WIN+X=> Device Manager
Choose an item Video adapters -> your_card
choose Delete device, tick the item Uninstall Driver Programs and agree:

reboot:

after the reboot, update the hardware configuration and point to the location of the driver for your card. If these are not drivers in their pure form, but an installer, run it. If this is not the case, Windows will automatically download the appropriate one from its servers. As you understand, it is not a fact that it is suitable. So native drivers are sometimes the most elementary way out of the situation. Although experience suggests that the described problem is a Windows problem.

That's all I wanted to say. We unsubscribe according to the results, to whom it helped or not.

Good luck to us.
