After loading Windows there is a black screen and cursor. Black screen when loading Windows: what to do if the computer does not turn on Black screen when turning on a windows 7 laptop

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 that occur when loading the system

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

Additionally, the black screen may also appear in different ways, such as with or without a cursor.

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

• An internal error in the operating system, due to which it cannot adequately interact with the graphical environment;
• Driver failure for the video card (incompatibility with the installed version of Windows);
• Failure of the computer's internal storage;
• A critical malfunction of Windows OS, preventing it from loading adequately even in Safe Mode;
• Other PC hardware conflicts;
• The operating system is unable to wake up from sleep mode.

Boot Windows in Safe Mode

Initially, you should try to boot the system securely.

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

Turn off your computer to stop any 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 required option.

In this case - Safe Mode.

If the computer starts in this mode without any problems, then we can assume that the settings of the system itself have failed.

This additionally includes the appearance of an error after the next update in the OS registry, and drivers not working properly.

Here, activating the operating system is the first step towards fixing the problem.

Many people use an unlicensed copy of the operating system, the next update of which sometimes ends with the appearance of a black screen.

This occurs due to the inability of a “pirated copy” to pass identification on the Microsoft Corporation website.

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 must be licensed.

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

Equipment malfunctions

Monitor and system unit

The cause of a black screen may be the presence problems with equipment.

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 occurs on a laptop, then the reason is almost always not related to the display, since in order for it to be damaged, it must be subject to a strong mechanical impact, for example, a fall or impact.

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

On a computer, a black screen when logging into the system 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 tightness of its mounting in the motherboard slot, as well as the stability of the supplied voltage and cooling (if it is not passive).

Checking the functionality of video card drivers

Check the status of video card drivers that may conflict with the system.

To do this, you need to restart the operating system in safe mode by activating the low-resolution video mode support item in its menu.

After logging in, go to the control panel.

To do this, right-click on the menu "Start" and select from the list that appears "Device Manager" .

Select there in the section "Video adapters" installed video card and go to its properties window.

On the tab "Driver" click on the button Delete.

Then restart your computer and install the factory drivers that came with your video card.

You can go to its manufacturer’s website and download their latest version there.

If you don't know which drivers to look for, call the tab « Execute» using a key combination Win+R.

Enter in the opening field

and click on the button “ OK».

In this case, the DirectX Diagnostic Tools window will appear, which will display the name of the existing video card.

Using the information received, downloading the necessary ones is quite simple.

Resolving a possible software component conflict

A characteristic feature of this option is that after several reboot attempts, the computer still manages to start.

The “treatment” method will be approximately similar to the previous case, the only difference here is that you need to select the item in the Windows configuration section "Enable Safe Mode" .

Then, in the top line, we sort the installed software by download date.

Now, having looked at the list of installed software, you need to find the culprit of the problem and remove it.

The best way to do this is through a third-party program such as CCleaner, since it will also get rid of any residual items after deletion.

To get rid of a suspicious program, you need to go to the section "Service - Uninstall programs" and select the option you need.

Motherboard Drivers

A black screen is sometimes the result of a conflict between motherboard drivers and the system.

Repeat the previously described steps to remove and install a working program in its place.

Be careful when working with drivers, otherwise you cannot avoid completely reinstalling the operating system.

To protect yourself from this, set a checkpoint to which, if necessary, you can roll back the system.

In the case when, after replacing the drivers, the black screen periodically continues to remind itself, continue searching for the cause.

Try to remove all programs that may cause a system conflict, and also test your computer for various malware.

Start the system again in safe mode and open the control panel by right-clicking on the “ Start».

From the list present, select " Programs and components" and click on it.

Carefully analyze which programs have been installed recently and may cause a conflict situation.

Remove them using standard Windows options or a third-party program.

One of the best currently is CCleaner.

The program is clear and quite effective, allowing you to remove all accumulated file garbage.

All you need to do is check the boxes in the section « Cleaning» opposite the required items.

After the analysis carried out by the program, press the button « Cleaning» and wait for it to complete.

By going to the tab « Service» , you are free to choose the programs to be removed.

Select the one you need and click on the button « Uninstallation» .

Restoring the system registry

The periodic appearance of a black screen may also be a consequence of damage to some system registry data by malware.

To get rid of this, you need to restore it to fully working condition.

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

Windows 10 makes this easier. Right click on the menu « Start» and in the list that appears, select the item « Execute» .

In the input field you write

Regedit

and press the button OK.

Windows Registry

The system registry editor will open.

In it you need to find a line called " Shell" and double-click on it.

When the window for changing the string parameter appears, delete all entries in the parameter “ Shell", and in the empty field enter

Explorer.exe

After this, click on the button OK, saving the changes made.

The final step is to restart the computer, allowing the settings to take effect and debugging the registry.

If the actions are performed correctly, the registry will be restored, and the black screen will no longer appear.

System recovery using third-party programs

Debug work explorer.exe You can do this not only manually, but also using the small AVZ utility.

It must first be downloaded and installed on your computer.

The main window of this antivirus utility contains several menu items, including the following:

• File;
• Service;
• AVZGuard;
• AVZPM;
• Reference.

Select an item « File» , and from the list that appears - » .

After this, the settings window for the recovery function will open, in which you need to activate the 8th and 16th lines (restoring Explorer settings and restoring the Explorer launch key).

By checking the boxes next to them, all you have to do is click on the button Perform marked operations and wait for the process to complete. When completed, be sure to restart your computer.

Autoload

It often happens that a startup program, or a very large number of them, can cause the periodic appearance of a black screen.

Reduce the number of programs launched from Windows to a minimum and, if this does not remove the existing error, it will at least speed up the startup of the operating system itself.

It is easy to fulfill this condition using the command

Msconfig

which should be entered in the menu window "Run" .

By clicking on the OK button you will be taken to the window "Windows Task Manager" , in which you should go to the tab.

This tab displays all programs participating in the joint launch with the OS.

Select all unnecessary programs and click the Disable button.

System rollback

With a solution to the black screen problem often A simple rollback of the operating system to a restore point will help.

Although quite often users disable this function, considering it almost useless.

But with its help, sometimes it is quite possible to avoid reinstalling Windows, returning to the moment of maximum stable operation.

It is quite possible to perform this operation after loading into safe mode.

Conflict with antivirus software

The inability to start often provokes a conflict between the OS and the installed antivirus program.

The latter sometimes mistakenly blocks various system files.

To return the computer to normal operating condition, you will need to terminate some antivirus processes.

Using the button combination C trl+Shift+Esc Open the task manager window and selecting the " Processes» those related to the antivirus - complete them.

Remember that this is a temporary measure and they will be launched again with the next system start. To avoid recurrence, you should create certain exceptions for your antivirus application.

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

Go to the program settings window and select active protection.

Then go to the file system screen tab and select the partition 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 to start the explorer.exe process, you need to use the menu "Run" and enter the name of the process in a special window.

After clicking OK, you need to restart the computer.

Virus scanning and removal

Malicious programs, like no other, are the culprits of operating system failure.

Therefore, it is necessary to check not only the partition with the system, but also the entire hard drive to identify them.

There are different ways to carry out this check.

One of them would be to use the utility 4MRecover, which is present on the boot disk LiveCD4MRescueKit.

Another option is to check the hard drive on another computer that has good anti-virus protection.

True, this is not very convenient, since you will have to remove the cover of the system unit and disconnect the disk itself.

Black screen appears during Windows reinstallation

In this case, there are several solutions:

1. Use another media with the image for installation, or write a different version of the OS onto it

2. Check the Windows volume for bad sectors, as they can disrupt the installation process.

The flash drive or disk should be checked for other types of damage. For example, mechanical;

3. It’s worth trying to select another local disk as the system disk.

Fighting viruses and other malware

Fraudulent software is quite developed and harms not only user data, but also important system utilities.

In this case, the cursor also appears occasionally, and besides, it is even controllable.

A virus attack may not be confirmed, but it’s still worth a try.

Nowadays there are a lot of anti-virus software components on the market, but it would be best to use the laboratory’s development Dr. Web called CureIt.

With its help, the user is provided with the function of superficial analysis of files on the PC, and a more detailed check, this is what the start menu of the utility looks like:

If Windows won't boot, you need to take the hard drive and connect it to another PC.

Using this program is very simple: you just need to "Hard Drive" , as well as the strength of the check.

If the above method does not help, you should look for the reason in something else.

Creating a recovery flash drive and reinstalling Windows

One of the toughest methods among all those proposed is to completely reinstall the existing OS to a more stable one.

Nowadays, the need to burn an image to disk is now enough to simply create a flash drive with the installation program.

This is easy to do using any specialized program.

Rufus

One of the best available is Rufus.

The utility, despite the paucity of the external interface, copes with its purpose quite well.

It’s very easy to use: you just need to go to the "Device" select the NTFS formatted boot volume and image file, and then click "Start" . View of the application start page.

UltrISO

This program has a slightly larger arsenal of tasks than the previous one.

To create a bootable USB flash drive, you must reformat it to NTFS.

When you launch the program, you will see the following window:

3. Choose the path to the image;

The worst case scenario when a black screen appears is that the hard drive has failed.

Initially, this reason can be answered if a cursor is visible on the display, since this means that the device is functioning.

If you see a completely dark screen, most likely this is due to the fact that the drive simply does not work and, as a result, is not displayed in the system.

Definition of bad sectors

It’s worth noting right away that damaged sectors are almost impossible to restore.

However, they can be closed for reading and writing, so they will not interfere with further work. The origin of these damages is of two natures:

• Logical. It occurs due to a mismatch between the ECC code and the contents of the sector. Essentially, these fragments are not broken, but only temporarily unreadable, so they must be repaired;
• Mechanical. Broken sectors of this type are caused by strong impacts or strong shocks during operation. These particles have completely failed and cannot be repaired.

To find and restore the Windows operating system, there is a built-in checking utility – CHKDSK.

This component is launched in two ways:

• Via command line. To do this, call the “Run” menu using the Win+R combination and enter cmd into it. In the window that opens, enter the following values: CHKDSK C: / where C is the letter designation of the local disk being checked;
• Through section properties in the tab "Computer" .

If the check shows that there are bad sectors in the PC memory, the utility will offer to repair or close them.

To prevent the occurrence of the damage in question, it is necessary to periodically clean the hard drives from accumulated dust and dirt.

In addition, SSDs do not withstand drops very well, so you should try to prevent them.

To prevent logical damage, you additionally need to defragment partitions from time to time, as well as optimize them.

By following these tips, you will greatly reduce the load on your hard drive and increase its durability.

Black screen when loading Windows 10

Some Windows 10 users complain that during the boot process, instead of the usual splash screen, a black screen is displayed. Most often, this problem plagues those who installed Windows 10 by updating an older version of the OS.

Hello. Do you have any USB ports? How did you determine this? The system, as far as I understand, does not boot. Or is it impossible to boot from a flash drive?

Disconnect all devices from your computer. Leave only the mouse, keyboard and monitor.

To solve the error No boot disk has been detected or the disk has failed, you can try resetting the BIOS settings to factory settings.

About fifteen years ago, my friend, an avid Beatle fan, decided to write a book about the Beatles. Until then, he had no experience working on a computer. I turned to a private craftsman (he didn’t know me at that time), he assembled a computer for him, as I understood, from what was no longer needed and thrown away anyway...)) Four memory sticks, a Pinnacle card, a DVD-writing drive drive and three hard drives of different capacities... Later, for some reason, his Internet provider installed an additional network modem...
In short, the computer's power supply was clearly overloaded and the computer was not cooled well. The system “crashed” twice a week... The person who assembled the computer quickly got tired of it and found a plausible excuse to get rid of this client’s problems.
This is where I turned up.)))

Reinstalling the system was not always successful. I didn’t have to do it every time and, at some point, I began to use a block of three fans from an old Soviet computer. I removed the cover of the system unit, disconnected two of the three hard drives, directed the air flow inside the computer and... installation success is almost guaranteed.....
After some time, my friend learned to install the system on his own, without my help, and when he got tired of it, he bought a new computer.

The case I described is, of course, not entirely common, but, as it turned out later, good airflow during installation of Windows never interferes - it helped me two or three times in my memory.

I have a terabyte “Seagate”, which was not helped by any cooling and I was never able to install the system on it. And judging by the state of its connectors, approximately several thousand people tried to do this before me...)))
However, for me it has “taken root” in the box for an external self-powered hard drive NexStar. Every cloud has a silver lining.)))

Very often people underestimate the importance of the power source, or more precisely, the power system, and even more precisely, the frequency parameters of the integrating chains. Usually, having estimated the power consumption by eye, they install a power supply with a small margin, without thinking about other parameters at all.
During the operation of computer chips, high-frequency “crawls” occur on the power buses, which can greatly affect the performance and even the serviceability of RAM chips, etc. It is important that the thickness of the tracks on the printed circuit board is sufficient and that ““ smoothing capacitors.
When developing computer technology, experienced specialists place several capacitors on a chip, differing in capacity by one order of magnitude, to effectively smooth out ripples. For example, 1uF electrolyte, 0.1mf and 22nf ceramics, in close proximity to the chip.
Soviet electronics, which over the past three decades have all gone into dredges, were not without reason “stuffed” with ceramic thermostable capacitors with a high palladium content.
Nowadays, everyone wants to save money, we want to buy a “cooler” motherboard and cheaper, and manufacturers want to sell us more and do not install smoothing capacitors in the required quantity (to reduce the cost). Everyone saves and relies on each other, but the end result is a lottery.
As a result, we get a power supply of, say, 500 W (power supply manufacturers also like to save money), in practice, at half the load it no longer “pull”, and if you look at the power bus with an oscilloscope, the ripples can reach half a volt or more.
A sign that the “mother” is not in order is the swelling of electrolytes - high-frequency “breakthroughs” are destructive for them, they overheat and explode when they swell.

Installing Windows puts a serious load on the entire system. The hard drive and processor memory are working at full capacity, it all gets hot and can give an error at any stage of the installation. A comparable load can occur when playing, for example, tanks. But if we are “knocked out” of the game, so what? - they came in again and didn’t pay attention... But if Windows failed during installation - yes, we’ll notice right away...

My life experience suggests that most failures occur for reasons not related to the programs - dust interferes with cooling, the fan is not lubricated and rotates poorly, electrolytes are swollen, microcracks have appeared, again, from overheating, and people also have a lot of cockroaches in their apartments, who strive to hide in a warm computer and lay their offspring there...

Suddenly, after the next launch of Windows 7, instead of the account login screen or desktop, a black background with a cursor on it may appear. Before we begin solving the problem, let’s delve into its essence, because even a few template instructions for different cases will not always help.

Most often, a black screen and a cursor on it are the result of a virus or malware. Such a program interferes with system settings, making it so that instead of the explorer.exe process it starts itself or completely replaces the above-mentioned file (many remember the Win32 family of viruses that hid files and directories, replaced them with their own “bodies” and even copied their icons for camouflage). After all, he is responsible for the Windows graphical interface: everything that the user sees on the desktop, etc.

One cannot help but recall the Avast antivirus, which tends to block system processes, including explorer.exe, due to excessive activity when starting the PC.

The likelihood of sudden conflicts between video card drivers and the operating system is low, although if they have been recently updated, it increases significantly. And drivers downloaded from nowhere or the use of driver packs only fuel the situation.

More deplorable will be the appearance of bad sectors on the hard drive, especially when they contain fragments of system files, such as explorer.exe. We won’t ignore partially damaged RAM sticks either, but last but not least.

First of all, let's try to start the computer in one of the additional boot options - from the last successful configuration. It is a set of system parameters stored in the registry for the state of drivers, applications and services with which Windows 7 successfully booted for the last time. If, before restarting or shutting down the PC, you installed something, edited the registry or the list of automatically launched applications, this method will clearly help. To implement it we do the following steps.

1. Let's reboot.

This is done using the Reset key or through the task manager.

• In the second case (it is recommended to use it) we call the dispatcher using Ctrl + Alt + Del.
• Move the mouse cursor to the “File” main menu item and call the “New task” command.

• Execute the command “shutdown /r” to reboot the system.

1. After the BIOS information appears, click F8 until a menu of additional boot options appears.
2. Using the cursor keypad, select “Last successful configuration” and press Enter.

Didn't help? This means the source of the trouble is different. Let's move on.

Avast

If the “seven” is protected by a comprehensive antivirus solution from Avast, the application may be the culprit for the fact that the explorer does not load. Removing the antivirus is not an option, but adding the file with which the problem is occurring to the exceptions is necessary.

It’s not relevant for all versions of Avast, but it’s worth a try since similar behavior has been noticed.

1. Open the Task Manager.
2. We launch the “AvastUI.exe” process, as in the previous case, by finding the executable file in the folder with the installed antivirus (in Program Files).
3. In the application menu, click “Security”.
4. Then go to the “Antivirus” subsection, where we click on the “Behavior Screen” tab.

1. Click “Browse” or enter the path to the reliable process manually - as shown in the screenshot.

1. Click “OK” and restart.

Has the blinking cursor appeared on a black background again? Let's move on.

Manually launching Explorer

There are several simple ways to open the program responsible for the graphical interface on the problematic computer.

1. If we stop at this option, we reboot again, and after completing the hardware self-test procedure, press F8.
2. In the window, select “Safe Mode with Command Line Support.”

1. In the CMD text line we write “explorer.exe” and press Enter.

If the process does not start, then the corresponding file is damaged, missing, or cannot be accessed.

This will help with system rollback, which we will touch on later, restoring the “seven” from an installation flash drive, fighting viruses and their consequences, or editing registry entries. In the latter case, you will have to get a boot disk with an antivirus program, start from it, selecting the CD/USB with the antivirus program distribution in the BIOS. Depending on it, the method of starting a scan may differ, but the meaning is obvious: we find and remove all viruses at least on the system volume.

If viruses are annoying

Even a laptop that is not currently infected with viruses can crash, displaying a black screen without or with a cursor. By the way, in the first case, the source of the problem may be the video driver. And all because the virus did its own thing, replacing the path to explorer.exe with its own. It is noteworthy that the following method works even without booting into safe mode, and you can also call the Registry Editor through the task manager.

1. Open the “Run” window through the task manager.

1. We write “regedit” and press Enter.

1. Expand the HKLM branch.
2. Go to the Software section.

1. We follow the path indicated in the screenshot.

1. Open the Shell key editing window.

1. In the “Value” field, set “explorer.exe” and apply the settings.

1. Let's reboot.

If this does not help, you will have to return to one of the previously saved states of the computer’s operating system.

Rollback

Here we will engage in time travel, provided that the system recovery function is activated.

1. Through the task manager, open the command execution dialog.
2. We register rstrui.exe and execute the command.

1. We indicate the recovery options (it makes sense to select the last created rollback point before the black screen appeared or stop at the recommended one).

1. Click “Finish”.

1. We get acquainted with the warning and click “Yes”, but there is no other choice.

Once the process is complete, a notification will appear.

The next time you turn on your PC, the desktop should appear.

When the graphics driver is naughty

Rolling back drivers during a system rollback is extremely rare. It’s good if the graphics driver was installed quite recently, but if it was installed a couple of weeks ago, when resuscitating the “Seven”, many files and applications may suffer. Rolling back the driver will help you get rid of such software, and only if the problem does not occur when you start it in safe mode.

1. In the “Driver” tab, click “Roll Back”.

You can also try to remove or update the video adapter driver by downloading it from the official website.

Before this, you should test the RAM sticks using a utility like Victoria 4.47, check the HDD for failed memory cells (chkdsk C: /f) and the integrity of important system resources (command “sfc /scannow”). They are executed via the command line.

Black screen after standby

After resuming from standby mode, a black background may appear instead of the desktop or user selection interface. In such cases, there will be several options, depending on the situation:

• rollback or install an older version of the graphics driver if problems began after updating the video card driver, especially when using driver packs or installers downloaded from third-party resources;
• alternately switching between the four main values ​​of the ACPI Suspend Mode parameter (responsible for software power management of computer components), located in the BIOS section called Power;
• reinstalling Windows 7 using the original image, and not the next author’s assembly - it is likely that this caused the problem (removing and disabling some system functions to save disk space and facilitate assembly could have had an effect);
• updating drivers for USB controllers, mice and keyboards downloaded from their official support resource;
• disabling the PC to go into standby mode;
• prohibiting one of the input devices from waking up the PC from standby mode.

Let's look at the last option in more detail. You can restore your PC using a mouse or keyboard. It is possible that one of the devices is blocking the computer from returning to a normally functioning state, and this is easy to determine, at least by the increased activity of the fan blades. In this case, deactivating the option to disable sleep mode for the mouse or keyboard will help.

Do not disable it for both devices at the same time, because you will not be able to exit sleep mode later!

Sometimes, when starting a computer, the user is greeted with an unpleasant surprise in the form of a black screen. This device behavior occurs caused by:

• pirated software;
• malware;
• incorrect operation of the discrete video card driver;
• unfinished installation of updates;
• damage to system unit components.

Such a malfunction can occur due to a number of reasons, so finding it is the key to solving the problem.

Starting Safe Mode

To restore correct operation, you will need to start safe mode. You will have to act by touch, which means you need to be careful. After several key presses Backspace or F8 you need to click on the button 5 times tabs and then press Enter. Next press again Up, after which again Enter, while holding Shift. These actions will lead to the mode opening recovery. The screen will still remain black, so you won't be able to verify this with your own eyes. Here you need to make the appropriate settings:

• three button transitions Down, further Enter;
• two button transitions Down, again Enter;
• then you need to press the key twice Left;
• after that, another transition with the button Down And Enter.

If the display display worked correctly, you would see the following picture:

After the above manipulations, the OS will start with the settings marked with arrows in the image. Low resolution may help to see the image.

Troubleshooting

Windows is not activated

This situation is often encountered by users who have a machine with unlicensed software installed.

To avoid having to deal with annoying notifications and the resulting inconveniences, you need to get rid of from the corresponding utility. She included in the package one of the updates. To do this you will need a separate software solution such as RemoveWAT.

After downloads And launch Just press one button and the problem will be solved.

The computer is infected with a virus

The malware modifies deep Windows settings configurations, resulting in changing the appearance of the interface. If no changes have occurred after removing the malware, this does not mean that the destruction of the virus was unsuccessful. The issue may be that the settings were not set before the initial version.

To troubleshoot necessary:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

There are two options here, Shell And Userinit, whose default values explorer.exe And c:\windows\system32\userinit.exe respectively. If this is not true it is necessary reinstall parameters and restart system for them to take effect.

It's also worth checking out the thread HKEY_CURRENT_USER\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon, where such variables should not be located. Otherwise, they are subject to destruction.

Non-working video card drivers

They must be removed and new ones must be installed in their place. For this necessary:

However, this method is unsafe because some components may remain in the system even after removal, which can lead to conflicts during subsequent updates. Therefore, a more competent approach would be to use specialized utility Display Driver Uninstaller, which is publicly available.

The final stage is from the official website of the manufacturer and its subsequent installation.

Black desktop without shortcuts

Microsoft works to optimize the software and updates it regularly. During the installation process, the system asks the user not to turn off the computer, but there is not always time or opportunity to do just that.

Terminating updates may result in a black screen upon subsequent boot. This process sometimes lasts up to 30 minutes, which is associated with large updates or low hardware performance. When the process is completed, the computer will work properly again.

Computer problems

The first step is to turn off the device. After that it's worth inspect wires and make sure they are not damaged. You also need to check the cables, as well as their interfaces, for mechanical damage.

The motherboard must also be in integrity and safety. But even in this case, it can cause a black screen due to a large accumulation of dust.

The board also has batteryCMOS, which is responsible for the safety of BIOS settings. It may run out of power, preventing the system from booting. In this case, replacing it will solve the problem of the black screen. But most often the solution lies in operating system malfunctions.

If all else fails

There is a procedure for rolling back the OS to the latest working update. To save all files, you need to go to " Control Panel» → « System» → « System protection"and in the protection settings enable all logical drives. Otherwise, during subsequent recovery, only the system disk will be restored.

This is where it happens recovery by pressing the appropriate button.

A black screen when booting a computer or laptop indicates a serious problem with the software or hardware. At the same time, the fan on the processor cooling system may rotate and the hard drive loading indicator will light up. A significant amount of time and nervous energy is usually spent on solving such problems. In this article we will talk about the causes of the failure and how to eliminate them.

There are several types of black screens and they all appear under different circumstances. Below is a list with explanations:

Option 1: Blank screen with cursor

As mentioned above, such a screen informs us that the GUI of the operating system is not loading. The Explorer.exe file is responsible for this ( "Conductor"). Startup error "Conductor" may arise due to its blocking by viruses or antiviruses (in pirated copies of Windows this is quite possible - there have been cases), as well as due to banal damage by the same malicious programs, the hands of the user, or incorrect updating.

In this situation, you can do the following:

Option 2: Boot disk

This error occurs due to a software failure or a malfunction of the media itself or the port to which it is connected. This can also happen due to a violation of the boot order in the BIOS, damage to boot files or sectors. All these factors lead to the fact that the system hard drive simply does not start working.
The following steps will help solve the problem:

• System recovery with a preliminary attempt to boot into "Safe Mode". This method is suitable in case of failure of drivers and other programs.
• Checking the list of devices in the BIOS and their boot order. Some user actions can disrupt the media queue and even remove the desired disk from the list.
• Checking the functionality of the hard drive on which the loaded operating system is located.

The information provided in the article above is suitable not only for Windows XP, but also for other versions of the OS.

Option 3: Recovery Screen

This screen appears when the system cannot boot on its own. The reason for this may be a crash, an unexpected power outage, or incorrect actions to update, restore, or change the system files responsible for loading. It could also be a virus attack targeting these files. In a word, these problems are of a software nature.

First of all, try to boot the system in normal mode - there is such an item in the menu. If Windows does not start, then you will need to perform a number of actions, in order:

1. Try to run the last known known configuration, if possible.

   

2. If it doesn't work, then it's worth trying "Safe Mode", some programs, drivers or antivirus may be preventing the download. If the download was successful (or not so successful), then you need to perform a “rollback” or restore (see below).

   

3. To launch the recovery environment, you need to select the appropriate menu item. If it is not there, you need to restart the computer and press the key the next time you boot F8. If even after this the item does not appear, then only an installation disk or USB flash drive with Windows will help.

   

4. When booting from installation media, at startup you must select the mode "System Restore".

   

5. The program will scan the disks for installed operating systems and may suggest changes to the boot parameters. If this happens, you need to press the button "Fix and restart".

   

6. If you are not prompted to automatically correct errors, you need to select the system in the list (most often there will be only one) and click “ Next».

   

7. You can try selecting the first item in the console - "Startup Recovery" and wait for the results, but in most cases it doesn’t work (but it’s worth a try).

   

8. The second point is what we need. This function is responsible for searching for restore points and rolling back the OS to previous states.

   

9. The recovery utility will launch, in which you need to click "Next".

   

10. Here you need to determine after what actions the download failed. After that, select the appropriate restore point and click again "Next". Don't forget to check the box next to the item "Show other restore points"- this can give additional scope for choice.

    

11. In the next window, click "Ready" and wait for the process to complete.

    

Unfortunately, this is all that can be done to restore the system boot. Then only reinstallation will help. To avoid getting into this situation and losing important files, make regular backups and create restore points before each installation of drivers and programs.

Conclusion

Thus, we have examined several options for the occurrence of a black screen when loading the operating system. The success of restoring functionality in all cases depends on the severity of the problem and preventive actions, such as backups and restore points. Do not forget about the possibility of a virus attack, and also remember about ways to protect yourself from this kind of trouble.
