Why is there a black screen when loading windows 10? Why does a black screen and mouse cursor appear? Reasons and their solution
One of the most unusual situations is when a black screen appears after updating or installing Windows 10, as well as rebooting the system. This happens at the most inopportune moment and many users decide to reboot the operating system to quickly correct the situation. In this article we will try to figure out this problem without reinstalling the system.
Basically, this problem occurs as a result of malfunctioning NVidia and AMD Radeon video card drivers, but there are also other reasons. The instructions below describe a situation (it is the most common) in which the same symptoms appear, namely the sound and operation of the device, while Windows 10 loads, and on the monitor there is only a black screen and a mouse pointer (and not always).
Note:Sometimes the black screen problem can happen because a second monitor is connected. You can solve this this way: first, disable it, if this does not affect the result, then try to log in blindly (the action diagram is described below in the Reboot section), then press the Win + P keys, as well as down and Enter.
Note 2: After the login screen, a black screen appears, in this case, you need to follow these steps. Press the on/off key in the lower right corner of the login screen, then press Shift and “Reboot”. In the list that appears, select the following items: Diagnostics, then Advanced options and at the end System Restore.
Reboot Windows 10
An effective way to correct the problem is to turn on Windows 10 again; for AMD (ATI) Radeon video cards, you will need to restart the device and disable fast system startup.Method 1 This will have to be done blindly. When the device boots with a black screen, then you need to press the Backspace key (it deletes characters). As a result, there will be no lock screen saver and all characters in the password entry line will be deleted if they were entered by mistake.
Then you need to switch the layout, if necessary, usually in Windows 10 the default is Russian, and you can switch using the Win + Space keys, then enter your own account password. After that, click and wait for the system to boot.
The next step is to reboot the device. This can be done by pressing the Win + R buttons, after 10 seconds again enter the following combination: shutdown /r, then Enter (you may need to switch the layout if the default is Russian). After a few seconds, press Enter and wait until the device reboots. After the operations have been completed, the image may appear on the monitor again.
Method 2Another method of rebooting the system in the case of a black monitor is to: press the Backspace button, spacebar or any character after the device is turned on, then the Tab button 5 times (as a result you will see the on-off icon), then Enter and the “ button Up", at the end - Enter. After the complex operation has been completed, your device will reboot.
Your computer does not restart in either the first or second case, then it is recommended (but it may be unsafe) to force shutdown the device by long pressing the power button. After that, turn on the device again.
After performing the above steps, a picture appears on your monitor, in this case the problem lies in the functionality of the video card drivers as a result of fast startup (it is installed by default in Windows 10). To prevent the error from happening again, you need to disable the default fast startup.
The process of disabling fast system startup:
Using Integrated Video
Your device has an output for connecting a monitor on the motherboard, and not from a discrete video card, then it is recommended to turn off the computer and connect it to this output, then turn on the device again.There is a chance that an image will appear on the screen after turning on the device (in the case when the integrated adapter in UEFI is not disabled) and it will be possible to roll back the video card drivers (using the device manager), reinstall them, or use system recovery.
Removing and reinstalling video card drivers
If the method described above does not resolve the problem, then it is recommended to remove the video card drivers from the system. This must be done in safe mode or with a low screen resolution. Let's look at how to do this on a black monitor (there are 2 methods for different situations).Option No. 1 On a black screen, press the Backspace key several times, then the Tab button 5 times, then Enter, then the up button while holding Shift, and Enter again. After completing the combinations, you need to wait a little until the diagnostic and recovery menu loads, as well as a system rollback - the user most likely will not see all this.
1) Press the down Enter button 3 times, the down button 2 times, Enter and the left button 2 times.
2) For devices with BIOS and MBR, do the following steps: down button and Enter. For devices with UEFI: press the down key 2 times, then Enter. If your software on your computer is not known, then you need to press “down” and when you get into the UEFI (BIOS) settings, you need to press the down button and Enter twice. Then press Enter again.
The device will reboot and provide boot options. Using the numeric buttons 3 - F3 or 5 - F5, launch low-resolution video mode or enable safe mode with loading network drivers. After loading, you can try to restore the system in the control panel, or remove the video card drivers, then restart Windows 10, after which the image should appear, and reinstall the drivers.
Option No. 2If the user cannot boot the computer using the previous method, then:
- login with password.
- On a black screen, press the Win+X buttons.
- then press up and Enter 8 times. This will open a command prompt from the administrator side.
Check the registry
You may see a black screen after logging in due to the installation of third-party software that is incompatible with Windows 10. You can check this in the registry. But here you need to remember that such a solution involves changing the registry. And if you make changes to this registry incorrectly, it can cause serious problems. Before taking any steps, it is recommended to backup your registry.Note: if the user has a bootable USB flash drive with Windows 10 or a recovery disk, it is recommended to use them. In this case, you can use restore points or a system reset.
We have listed all the manipulations that need to be carried out if a black screen occurs when starting a personal computer.
After the release of a new operating system from Microsoft, many people immediately rushed to install ten on their computers, especially since the manufacturer, this time, prepared a real surprise - the possibility of free updating of a previously installed seven or eight. Of course, if these were licensed versions. But, some users, immediately after upgrading the system, are faced with a rather unusual problem - a black screen when loading Windows 10.
The unusual thing is that the black screen after upgrading to Windows 10 does not seem to have its own code, which immediately confuses some people. Before you start fixing Windows 10 black screen, you should determine the cause of its occurrence.
Why does it occur
According to statistics, in most cases, it occurs due to a conflict with the drivers that are necessary for the operation of a graphics card from AMD. The new ten is still a fairly crude operating system. Therefore, it is not surprising that after upgrading to Windows 10, this problem arises, but before everything worked fine - the developers have already more or less figured out the previous generations of the OS, but the new product still needs to be worked on.
Do not panic ahead of time if it occurs during loading - there is a good chance that the problem can be resolved using fairly simple methods.
Troubleshooting
So, how to fix the situation if, after installing a new OS, the system does not start for a long time, and in the end it does not start when loading Windows 10?
First of all, it is worth noting that the solution to the question posed is simplified by the fact that the user has the opportunity to work with the installed system. Typically this problem manifests itself like this:
- After installation, Windows 10 takes a long time to load - black screen.
- After some time, access to the operating system appears - the start menu and mouse cursor work, and in front of us is a standard window of the new OS.
Therefore, the first step in our fight against the fact that a black screen appears when starting Windows 10 is to gain access to the system settings:
- Open the Start menu and look for settings.
- Go to the “System” sub-item.
Considering that the black screen with a cursor in Windows 10 is associated with video card drivers, we naturally look for the desired device: - Programs and Features menu.
- Scroll through the list and find the equipment you need.
- Remove all installed drivers.
Since it is associated only with the new version of the driver package from AMD, you need to search for the previous version of these files and install them in place of the deleted ones. How to do this correctly so that other conflict situations do not arise:
- Usually the entire package is included in an archive, which should be downloaded and unzipped to your desktop in a folder specially created for this.
- Go to the "Device Manager" menu.
- Find the hardware that is listed under the name "Microsoft Basic Display".
- Open settings, then update drivers.
- It is advisable to specify the path to the required components yourself. That is, show the system where the installation should be performed.
- After the process is completed, reboot the operating system.
Why shouldn't I choose the "Prepare automatic updates" option? The reason is that the OS will begin to perform an independent search and will definitely look for the latest version of drivers. Naturally, it will detect similar ones to those that were just deleted - and install them again. Where it leads? That's right - to the appearance of the same black screen, which we need to avoid.
Windows can be considered completely ready for use after the desktop and applications added to startup are loaded; until this point, the system may experience slight freezes. But it may also happen that at some stage an error occurs and Windows will not be able to boot completely. A typical example of this is the appearance of the so-called black screen of death or Black Screen.
It looks like this: the computer successfully passes the POST procedure, the system boots normally, but the desktop does not appear. Instead, after loading Windows 7/10, the user sees a black screen with or without a mouse cursor. Another variation of the same problem is that a window appears on a black screen with the error “The script file C:/Windows/un.vbs cannot be found.” This happens most often because the Explorer file responsible for the operation of the system’s graphical shell cannot start normally.
There may be several reasons for this, but usually it is either some kind of conflict in the operating system, or the consequences of viruses. The likelihood that the problem is caused by hardware problems, in particular, the failure of the video card, is small, otherwise the screen would be completely black, and there would be neither a cursor nor the Windows logo on it. So, what should you do if you get a black screen when loading Windows 7/10? In any case, do not make hasty decisions and do not rush to reinstall.
Delays after installing system updates
It has been noticed that sometimes Black Screen appears immediately after installing cumulative or major Windows updates. This may be temporary, so you may need to wait a bit. If the desktop does not appear within an hour or two, then this should be a cause for concern. Restart the computer, not with the Reset button, but through the Task Manager called up by pressing Ctrl + Alt + Del.
Select from its menu File – Create New Task and run the command in the window that appears shutdown /r /t 0.
If the black screen appears again when starting Windows 7/10, most likely you have become a victim of an error when installing updates or a bug in the updates themselves.
Error during update installation
The appearance of a black screen when loading Windows 7/10 can cause a failure during the installation of updates, for example, a sudden shutdown of the PC at the time of installation. In addition, the updates themselves may contain bugs, which Microsoft itself admits. If you have every reason to believe that updates are the cause of the black screen, you need to remove them.
It is best to do this in safe mode. To enter it, press the F8 key during reboot or run the command in the window for creating a new task msconfig.
After the system boots, go to Control Panel, launch the Add or Remove Programs applet and click on View installed updates on the left.
Uninstall the latest updates and then reboot.
Software conflict
Everything that has been said regarding updates is also true for video card drivers, screen adjustment programs, etc. If the problem appeared after installing a new driver, then you need to remove it, again by booting into safe mode. The same applies to installed new programs.
Damage to registry entries, viruses
An even more common cause of the problem is the action of malware that overwrites the parameters in the system registry that are responsible for launching the graphical shell. Then you will see a black screen when you start the computer in both boot modes. In this case, we do this. Using Task Manager, open with the command regedit registry editor
Expand the thread:
HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/Winlogon
Pay attention to the parameter Shell. Its value must be specified explorer.exe and nothing more.
If something else is specified, then you need to replace this entry with explorer.exe, otherwise the graphical shell will not start either in normal or safe mode. If the Shell parameter does not exist at all, create it and set it to the specified value. At the same time, check the parameter value Userinit, it must be C:/Windows/system32/userinit.exe.
Note: on 64-bit systems you should also check the Shell and Userinit values in the key HKEY_LOCAL_MACHINE/SOFTWARE/Wow6432Node/Microsoft/Windows NT/CurrentVersion/Winlogon and correct them as shown above.
After making changes to the registry, reboot as usual. This method has proven to be effective in many cases of PC infection with viruses; it allows you to quickly eliminate the black screen and cursor when starting Windows 7/10, however, it does not solve the main task - removing malware from the system, so after loading the desktop you need to carefully check the entire contents of the disk antivirus scanner.
Failure to install updates, viruses, or incorrectly functioning video card drivers are the main reasons why the user sees a black screen and cursor when turning on the computer. In fact, there may be more. The appearance of Black Screen was noted when changing the settings of the administrator account, after optimizing and cleaning Windows with third-party tweakers and cleaners.
It may not be possible for a novice user to determine what exactly causes the error. If, when starting Windows 7/10, a black screen with a cursor continues to appear, it is best to roll back to the system. Such points are automatically created by Windows when important changes are made to the system - installing programs, drivers, etc. It is best to use the installation disk with the distribution kit of your version of the system for these purposes.
Boot from such media, wait for the installation wizard window to appear, click “Next” and then “System Restore”.
Then we choose Troubleshooting - System Restore.
Specify the target system and click “Next” in the window.
Select the desired point and follow the further instructions of the wizard.
Once the procedure is complete, you will be prompted to restart your computer.
Rolling back to a restore point is an effective way to restore functionality to a damaged system, but this is only possible if the appropriate protection feature is enabled in Windows settings. Its capabilities, however, are also limited. If your computer won't start, a horizontal cursor is blinking on a black screen, or error messages appear at the top, these could all indicate more serious problems. In such cases, the need to conduct hardware diagnostics or restore the system partition from an exact copy (image) cannot be ruled out.
- Hello admin! Soon July 29, 2016 - the free upgrade to Windows 10 expires and I decided not to wait for the last day and upgrade, but in update process Windows 8.1 to Windows 10 A black screen appeared on the monitor screen, I waited for half a day, but the screen remained black.On one forum on the Internet they suggested restarting the computer and repeating the update process, but unfortunately after rebooting I cannot get into Windows 8.1 to start the update process again, the screen still shows the same black screen. What to do?
- Hello! I updated my Windows 7 to Windows 10, but the joy was short-lived, after two days the laptop began to turn on with a black screen, then twenty minutes (and sometimes an hour) passed, and Win 10 still loaded. Is there any way to get rid of this black screen or roll back to Windows 7?
Hello friends! The ability to freely upgrade current Windows 7 and 8.1 to Windows 10 will end soon on July 29, 2016. Millions of users around the world have already done this, taking advantage of the upgrade process before installing Windows 10 from scratch. This means saving data on drive C, installed programs, and transferring activation. However, alas, throughout almost a year of hype with upgrading to Windows 10, this process did not always end successfully and computer services began to bring computers and laptops with the so-called “ Black screen Windows 10", also on various forums on the Internet, requests for help in solving the same problem began to appear.
In my experience black screen windows 10 may appear in three cases:
- A black screen in Windows 10 appears when logging into the operating system some time after a successful update. One of the scenarios for this error: a black screen with a frozen or moving cursor is replaced after a long time by the system starting.
- Another, more hopeless scenario: Windows 10 does not start, the black screen remains the top demonstration of the capabilities of the updated system, no matter how you restart the computer.
- The most hopeless option. Windows 10 black screen appears in the process of upgrading previous operating systems to Windows 10.
What reasons can lead to such a problem when upgrading the current version of the system to Windows 10? How to solve the black screen problem in Windows 10? I offer my solution to the problem of the Windows 10 black screen in the above cases.
Friends, if your Windows 10 previously loaded perfectly, but now “pleased you with a black screen,” then first try the keyboard shortcutControl-Alt-Delete launch task manager,
In the input field, enter explorer and click OK.
Your Windows 10 desktop will most likely appear.
What’s most interesting is that you can then turn off the computer and turn it on, and Windows 10 will start perfectly and work without any problems. I came across this bug many times, but mainly in those cases when computers and laptops with new hardware were updated to Windows 10.
Another simple way to get rid of the black screen. If you have a laptop, simply remove the battery from it and install it back, then turn on the laptop, it is quite possible that Windows will load instead of a black screen.
If these two simple solutions did not help you, then read the article further.
1. Windows 10 Booting: Disabling Fast Startup
We all know that Windows 10 has (and is enabled by default) Fast Startup or Hybrid Boot technology, which allows your computer or laptop to boot into the operating system faster after shutting down, but not after rebooting. Fast startup technology is based on hibernation. If fast startup is enabled in Windows 10, then when the system is turned off, it ends the user session, but does not end the system session, that is, it suspends all running system processes and services, writing information about this to the hibernation file hiberfil.sys. When you turn on your computer or laptop, the contents of the hiberfil.sys file are loaded into memory, due to which a quick startup occurs; this process is very similar to exiting the hibernation state.
I want to say that this technology does not always work correctly on all hardware (especially old ones).
If we are dealing with a system that still boots, albeit for a long time, after updating it to Windows 10, you can try to solve the problem with a black screen by disabling fast startup. Keys Win+Q We call the internal search, enter the request “Power supply”.
In the power settings window, click the inscription "Power button actions".
At the bottom of the window, in the column "Shutdown Options" Uncheck the “Enable fast startup” option. Save the changes.
If this move does not solve the problem with a black screen and a long loading time in Windows 10, the reason may lie in the video card driver. More about this below, in clause 4 of the article.
2. Windows 10 won’t boot: how to get into the system?
If all this does not bring successful results, you should try to get inside Windows 10 using safe mode. But to do this, you first need to be in action selection menu Windows 10
The existing theory that the action selection menu in Windows 8.1 and 10 can be accessed using the Shift+F8 keys while the computer is booting is difficult to verify in practice. The response time to these keys is negligible due to the shortened startup of Windows 8.1 and 10 systems. However, if someone manages to successfully test the operation of the Shift+F8 keys by getting into the action selection menu, then you need to follow this path:
Finally, directly in the safe mode window, press the F4-F6 keys in accordance with the desired parameters of this mode.
More reliable ways to start Windows 10 in safe mode are to use or. If any of these details are available, go to the article for further instructions.
What to do after booting into safe mode?
3. Screen resolution
A black Windows 10 screen may be caused by setting a screen resolution that is not supported by the video card. In safe mode without the video card driver running, the screen resolution will be standard - 1024x768, and the operating system will become visible. This will allow you to change the system screen resolution settings to lower ones. For example, you can apply the same 1024x768 standard to the system to check whether Windows 10 starts. The screen resolution in safe mode is set in the same way as during normal operation of Windows 10. On the desktop, call up the context menu, select "Display Options".
Extra options.
Setting the resolution.
4. Video driver
If screen resolution is not the cause of the black screen after upgrading to Windows 10, then you next need to check whether the video card driver is involved in the problem. Very often, after upgrading previous operating systems (Windows 7, Windows 8.1) to Windows 10, the old video card driver conflicts with the new operating system, causing the black screen problem. Uninstalling the video card driver in Device Manager can solve the problem. Expand the “Video adapters” item, right-click on the name of the video adapter and select “Delete”.
We reboot the computer and if it was a video driver conflicting with Windows 10, then the operating system will boot normally by installing the built-in video driver from Microsoft. After this you need or you can manually download the latest version of the video driver from the official website of the video card manufacturer.
5. Viruses
Viruses and other malware are a universal cause of many problems in the operation of the OS, including the black screen of Windows 10. You can check the system for viruses either in the same safe mode or by booting from antivirus bootable media. Many security software developers have such free emergency Live disks, in particular, .
- Note: The consequence of penetration of malware into the system may be damage to important system files, and the mere fact of neutralizing infected files with antiviruses may not be enough to restore Windows functionality. In this case, you need to resort to . The same process for cases where Windows 10 won't boot is described .
6. System rollback
If, before upgrading to Windows 10, the current Windows 7 or 8.1 was created restore point or backup copy(by third-party or standard system tools), and all the methods discussed above did not solve the problem with the black screen, it’s time to start rolling back the system. Rolling back Windows 10, including when it does not boot, is described in detail in the articles on restoring this version of the system and.
7. Cancel the update and return to the previous version of Windows
Canceling the update and returning to the previous version of Windows is, in fact, the only way to roll back the system while saving data on drive C, installed and configured programs, if there is neither a backup nor a restore point made in advance on the eve of the update. Having returned to the previous Windows 7 or 8.1, you can then try to update the system to version 10 in a new way. Naturally, do not forget to make a backup copy before the second update attempt in case of failure the second time. But you can only return to the previous Windows 7 or 8.1 within a month from the day of the upgrade to Windows 10 and if there is an untouched Windows.old folder on drive C. How to cancel the upgrade to Windows 10 using the standard functionality.
- Note: It is not recommended to resort to undoing the Windows 10 upgrade using third-party utilities.
8. Return the system to its original state
Just as the update process can be accompanied by errors and failures, the reverse process of canceling the update can fail, even if the month-long deadline for this operation has been met and the Windows.old folder has not been deleted. If canceling the update fails, there is neither a backup nor a restore point, and the question of returning to a previous version of Windows is a fundamental one. In this case, the data stored on the disk (C:), if it is valuable, must be moved to a non-system disk partition. In Windows 10 that won't boot, this is done, for example, using the one mentioned in . Each of them includes a file manager among the tools.
If we are talking about stationary PCs and laptops without a recovery environment from the manufacturer, and also if there is a desire to continue working with Windows 10, this system can be returned to the default settings, as if it were a normal system reinstallation process. This method of restoring laptops to factory settings has the advantage of automatically saving files to disk (C:). Read about this in detail.
