How cunning virus developers are! As soon as Microsoft releases another patch to the system, and anti-virus companies add an addition to the signature database, a new attack appears. What is happening is a typical eternal "dispute" between armor and a projectile, but everyone earns as a result. The only disadvantaged party is the user. He is no stranger to the consequences - stolen logins and passwords, overwritten data beyond recovery, lost system performance, and so on. Fortunately, there are certain rules that allow you to avoid the fact of infection in principle. Well, if the trouble did happen, all that remains is to restore the system to work using the usual methods.
One of the last "squeaks" of the viral fashion of recent years is the black screen displayed after loading Windows. In the current version (Windows Seven), the problem is that after a successful initial boot stage, and then the user authorization process, a black screen appears instead of the desktop and menu with shortcuts. The cause of the problem is incorrect entries in the registry keys responsible for loading the shell. The problem has several options, and they differ significantly. For example, if you get a black screen after booting Windows 7 (or on a previous and still popular system, you can do the following.
The first is to install the Black Screen Fix program. An indispensable condition for the effectiveness of this program is the removal of malicious software even before you run Black Screen Fix. For this purpose, the Drweb Cure IT utility is recommended, which has a huge anti-virus database. You can run it from a USB flash drive by pressing "Control, Alt, Divit".
The second, perhaps the surest way is to restore the system through the built-in service. It should be noted that in Windows 7 the procedure is greatly simplified. Just press F8 almost after the procedure for detecting hard drives - you can't go wrong! In this menu, select the startup recovery mode. Load into it by pressing the "Enter" button and select the first or second item. When you choose "Startup Restore", you save a lot of time, while choosing the second item "System Restore", you get a guaranteed result. After completing this procedure in the seven, the problem "after Windows boots - black screen" will be a thing of the past. Now be more discreet in your actions - use a limited account and install a good antivirus.
"But what if the system is not 7, but XP?" - asks the conservative reader, who stubbornly does not want to demolish his favorite system, which completely suits him, and install the "seven". Unfortunately, this also happens after booting into Windows XP. Black screen and that's it! Then you have to use the registry editor. Well, before that, thoroughly clean the system using the already mentioned Drweb Cure IT. Well, we press the coveted combination "Control, Alt, Divit" and we get the "Task Manager" window. Then, through the file menu, select a new task by typing regedit and now the main system administration tool is launched.
You need to go to HKLM and select the SOFTWARE bush. From here you should choose Microsoft and WindowsNT. Now we are looking for the Winlogon subsection in the Current Version folder, without it the system would not boot even to the authorization window. Check the value of the Shell parameter. It should be strictly explorer, without various add-ons. After all, the essence of the problem lies in the incorrectly loaded malware, and it is from here that the roots of the problem "after loading Windows - black screen" grow. It will also be useful to check the Userinit value, which is also critical for loading. That's right - userinit.exe.
It should be noted that this is not all the possible options that the insidious "infection" suggests. The task manager can also be disabled. Then the method with zeroing the parameters to the correct values \u200b\u200bis unlikely to work. We'll have to go a little different way. We launch it via F8 with command line support and, having loaded, give the regedit command. We consistently go through CureIT and follow the above recommendations, and then reboot. Black Screen after Windows Boot Problem Solved! If you are a fairly experienced PC user, it is recommended to use Zaitsev's Anti-Virus along with these programs, which allows you to both remove malware and automatically return the correct values \u200b\u200bto the registry parameters.
Almost every active computer user had to face problems when booting Windows, when after turning on the system unit, only a black screen or a proposal to choose a boot option is visible. This indicates that there is a malfunction in the system, which can be caused by a number of problems. It is good if the error resolves on its own upon repeated reboot, which happens quite often, but it is much more annoying when the system stops loading altogether or reports errors every time it starts.
Table of contents:Why does a black screen appear when I turn on my computer?
There can be several reasons for a black screen or error message when turning on the computer, both hardware and software. Most often, such a problem occurs after an emergency shutdown of the computer, that is, by stopping the supply of electricity to its components, for example, in case of an unexpected power outage in the room. Such an impact can lead to both software failures and the failure of computer components.
Naturally, this is not the only reason that leads to such "behavior" of the computer. Virus infection, mechanical disconnection of elements from the motherboard, unsuccessful Windows update - these and other reasons can lead to a black screen appearing when the computer is turned on or other symptoms prevent it from loading.
What to do if a black screen appears when you turn on your computer
Consider the main malfunctions that can lead to a similar problem, as well as methods for eliminating them.
There is no signal to display the image on the monitor
One of the most common problems that leads to the fact that when the computer boots up, the user sees a black screen. If, when loading the system unit, you hear a characteristic one-time, notifying about the passage of all check components and the absence of errors, the first thing to do is to check if there is a signal to display the image on the monitor:
- Check if it is connected to the system unit itself and if there is any damage on the cable through which the connection is established. If possible, connect the system unit to another monitor to make sure the display itself is working properly;
- Make sure it stands right. If it is not securely fixed in the connector, there is a chance that it will have problems with signal transmission.
In the case of a laptop, the problem in question is much more difficult to identify and fix. You can try to display the image from it on an external monitor to determine the presence or absence of a malfunction of the built-in display.
Windows crash, file corruption
A software issue can also cause a black screen to appear when the computer boots. Try booting your computer in Safe Mode. If the system unit on its own after repeated reboots does not offer to select the computer startup modes, you will need a bootable USB flash drive with the Windows distribution.
Through the BIOS, set that the information from the bootable USB flash drive was launched earlier than the operating system from the computer's hard drive. After that, using the installer tools, go to the Safe Mode boot.
Please note: If there is no bootable flash drive, you can try pressing the F8 key at the boot stage to bring up a menu of additional Windows boot options. But this will not always be possible.
It is worth noting that you can try booting in several secure boot options:
- "Safe mode”. This is the basic way to safely boot your computer. It assumes that at system startup a minimal set of services, utilities and applications will be loaded, which are automatically launched when the computer starts up. In this mode, there will be no Internet access;
- "Safe Mode with Loading Network Drivers".Unlike the previous version, this download launches the necessary software for the Internet;
- “Safe Mode with Command Line Support”.This mode does not imply a full load of the Windows interface, offering to control the system through the command line.
After booting the computer in Safe Mode, if there are no problems with this, you can proceed to eliminate the cause of the black screen at system startup. There may be several such reasons, and these are both problems with the files of Windows itself, and infection of the computer with viruses. Perform the following sequence of actions:
- Try to roll back the system to one of them, if they were created;
- If restore points were not created, try to remember what activities you have performed on your computer recently. Uninstall the programs after installing which there was a problem with the appearance of a black screen at startup. If installed or, uninstall or roll back them;
- Try to scan your computer with;
- Execute.
The steps listed should help you fix a software error that causes a black screen to appear when the operating system boots.
Mechanical damage to computer components
Perhaps the most unpleasant reason due to which a black screen appears on the screen when the computer boots. If one of the components fails, you need to determine which one, which is quite difficult to do. It is important to take into account that it is far from the fact that we are talking about serious damage to one of the key elements of the system unit. We recommend that you proceed as follows to identify and fix the problem:
Of course, it is much easier to establish the cause if there is a replacement element for each component of the system unit. For example, you can install a priori a working video card to check if the problem is related to a malfunction of the current video card module. But, if this is not possible, try to carefully check each component.
Nothing appears on the desktop at boot
Sometimes the situation develops in such a way that after eliminating the cause of the black screen when the computer boots, the user does not load shortcuts on the desktop and other active components. That is, after starting Windows, the user sees only the background image of the desktop. In such a situation, you need to perform the following steps to correct the situation:
As you can see, there are a lot of reasons for a black screen when the computer boots, and it is rather difficult to identify what happened to the system unit in a particular case. We recommend that to make it easier to deal with possible software problems, always make system restore points that can help if necessary.
Black screen when booting Windows 7 Is one of the most unpleasant things that can happen to our computer. But do not immediately take out the disk with the operating system and reinstall Windows 7, because this problem can be solved in other, easier ways. In today's article, we will take a closer look at how you can solve the problem of the appearance black screen on boot in windows 7 on our own, we will consider the reasons for the appearance of a black screen, and also learn how to prevent its appearance.
Black screen when loading Windows. What to do?
So, let's see why the operating system does not load and what causes the black screen in Windows 7? There are only two main reasons. 1 is a failure of the hard disk, which, as a result, leads to damage to system files and causes errors in the system. 2 are the most common viruses, Trojans and other malicious software. By the way, the black screen at Windows startup replaced, which everyone was so much afraid of, but unlike it, you can work with a black screen and try to restore the situation.
Black screen appears when booting windows 7
So, let's first analyze a situation in which the Windows 7 operating system does not load at all, and a black screen appears instead of the desktop. The first thing to do in such a situation is to enter Safe Mode. How it's done? First, you need to restart your computer and press the F8 key while it boots (it is best to start pressing F8 at the moment before windows 7 starts loading !!!). You will have a special menu in which you will need to select the "Safe Mode" item and press Enter:
Why is this done? Safe Mode is actually a very useful thing. The thing is that in this mode only the most necessary programs and services are launched, which are necessary for the correct operation of Windows. Also, this mode is very often used to log on to a system that has been exposed to viruses, as well as to restore deleted information or prepare a computer for reinstalling the OS. If you entered safe mode, you have a desktop, taskbar and shortcuts on the desktop, then this means that the black screen when loading Windows was caused by a failure of some service, program or driver that was installed shortly before the appearance black screen. In this case, it is best to do a system restore or remove recently installed drivers and programs through Control Panel -\u003e Remove Programs.
If the computer does not enter Safe Mode, then you need to restore the operating system, this can be done by inserting the operating system disc into the drive and selecting the appropriate settings. Sometimes there are cases that even after the system is restored, the black screen still does not disappear, in which case it is necessary to completely reinstall your OS to a new one. You can read how to do this in the article:.
Black screen at boot. If Windows boots
Very often, a black screen appears as a result of errors related to Windows activation. In this case, you just need to re-enter the operating system license code and confirm the entered data. But in most cases, this is still associated with the action of viruses and malicious software. If Windows boots up but instead of the desktop you have a black screen, then you need to follow these steps.
1. Execute the key combination Crtl + Alt + Del
2. Select the menu item Start Task Manager. If the task manager for some reason does not start, then read the article on how to fix it: the task manager does not start.
3. Go to the Processes tab and find the explorer.exe process there:
4. If you do not have such a process, then click on the new task in the menu and in the window that appears, enter the following phrase: explorer.exe. Then click OK:
You can read more about restoring the explorer.exe process in the article: how to restore explorer.exe
If after that the black screen disappeared, then the problem is almost solved. To complete, you need to click Start -\u003e Run and in the window enter the command: regedit and click OK. This will open the registry editor. Here you need to follow the path HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / WindowsNT / CurrentVersion / Winlogon and write the value explorer.exe in the Shell parameter (by the way, if something else is written in the Shell parameter, then it must be deleted !!! of the Shell parameter, only explorer.exe should be written !!!):
If these actions did not lead to anything, then the malware blocked the use of this process. To do this, go back to the task manager in the menu, select New task and in the window that appears, enter the phrase: iexplorer.exe and click OK. An internet browser will open. We find and download the AVZ antivirus program from the Internet. After that, we launch the program and perform the following actions:
Another option to eliminate black screen when booting Windows 7
To do this, during the black screen, very quickly press the Shift key five times in a row, you can also press the key and hold it for 10-15 seconds. After that you will have a window with the words "Enable Sticky Keys?" In this window, click on the link:
In the window that opens, in the line located in the upper right corner, write: "Task Manager":
After opening the "Control Panel" window, go to the "System" item:
In the window that appears, select the item "System Protection":
In the "System Properties" window that opens, click on the "Restore ..." button:
We put the bird and select other recovery points:
I hate to be trivial, but the so-called "black screen problem" when loading the operating system after turning on the computer is one of the most common problems faced by owners of both desktop computers and. The operating system that won't boot or the hard drive model is not very important in diagnosing the problem. We will tell you how to remove the black screen when loading Windows 7, 10 on a computer and laptop, the reasons for the failure later.
This guide will be supplemented, so do not hesitate to ask questions, as I can, I will clarify technical issues and solve your black screen problems.
Most likely causes of a black screen on boot
First, you need to list the most common problems that cause a black screen, after which the operating system does not boot (in other words, a black screen when the computer is turned on). In rare cases, after loading, the user sees not only a black screen, but also a cursor. The reasons:
- The operating system is in conflict, as a result of which it cannot load the graphical environment normally.
- Video driver problem (incompatibility with current operating system: e.g. Windows 10 or Windows 7, up to XP)
- Failed hard drive on a computer or laptop
- Windows has crashed and does not load correctly (not in safe mode)
- Other hardware problems or system conflicts
- Windows cannot wake up from sleep state
Start Windows in Safe Mode on your computer
One of the most likely reasons why Windows or another operating system does not load is a system conflict, due to which the OS cannot work correctly after turning on the PC. This can be caused, for example, by the fact that the user installs an incompatible program or drivers that conflict with Windows, and when the laptop / PC is turned on, the conflict will manifest itself from the unpleasant side - in the form of a black screen. How to remove it?
Fortunately, the Windows developers have provided a safe mode for logging into the operating system, which is specifically designed to address various compatibility issues. By entering safe mode, you can remove all problems on your computer, resolve conflicts, and then boot Windows in normal mode.
So, to enter Safe Mode on a computer:
- Remove from the computer all media and devices that may affect the boot Windows (flash drives, disks, etc.)
- Restart or turn on your computer, depending on its current state.
- To enter Safe Mode, hold down the F8 key during boot. If your PC (laptop or desktop version) has several operating systems, then select the appropriate one from the list and then hold down F8 again to go to Windows Safe Boot Mode.
Monitor or component problems
The reason for the black screen may lie on the surface: the monitor does not work. This may be due to the loss of contact between the monitor and the video card, or the power cable is damaged / not plugged into the outlet. Therefore, be sure to check the connection.
As for the laptop, it is unlikely that the matrix "fell off" from the motherboard. To disable it, you need good reasons: for example, mechanical impact on the display. At the same time, you will see that there are obvious damages on the screen: scratches, broken pixels, etc.
In addition to the monitor, we advise you to explore the system unit. Check if the video card is fixed in the corresponding socket of the motherboard, whether voltage is supplied to all PC components. This should be done only if you have the skills to assemble / disassemble a computer / laptop.
Resolving conflicts with the video driver, if the computer does not start, a black screen appears
An example of a similar problem:
Installed Windows 7, 10, restored to factory settings (native Windows image). But nothing helps. Simply put, with Windows 10 for the first time, everything is buzzing and everything is fine, but as the drivers get onto the video card (intel hd3000 and radeon 7600), flickering and a black screen occur, after which recovery and safe mode do not work. That is, Windows 10 dies after installing the drivers a black screen.
If you think that the black screen problem may be related to a conflict of video card drivers on a computer or laptop, then:
- In the Secure Boot menu, select Enable Low-Resolution Video.
- After successfully logging into the operating system account via Device Manager or Control Panel, uninstall the conflicting ATI / NVIDIA video driver.
- Reboot your computer
- Possible conflict between motherboard and video card drivers. You need to try different combinations of drivers. To avoid reinstalling Windows every time you experiment, create a restore point and roll back to the previous restore point when a black screen appears.
- If the OS boots in normal mode correctly (the Desktop and the Windows cursor appear), then the black screen problem is really associated with incorrect behavior after installing the drivers. Go to the video card manufacturer's website and download the latest version to your hard drive, try updating the drivers again.
- If the black screen continues to appear, try other solutions outlined in this guide - for example, uninstall the "harmful" programs.
Remove programs that conflict and block the OS from loading on startup
I can't start Windows 7. When you turn on the computer, after the words "start Windows" a black screen appears and then the computer does not boot. There is no cursor. I restart my computer, I am given a choice of how to boot Windows, I choose normal mode - and everything turns on, sometimes I need to restart several times. Normally, it does not turn on at all, I have Ccleaner, I use it, the antivirus is Avast, I do not update any drivers. What could be the problem?
In this case, the sequence of actions for elimination of the problem will be approximately the same as in the above case. The only thing is that in Windows Safe Boot Mode you need to specify the "Enable Safe Mode" item. Further, in this download mode, you need to go to the control panel and in the "Programs and Features" window, sort by the date the applications were installed. Analyze what you have installed recently: it is possible that conflicting applications are the cause of the black screen and inadequate loading of Windows from the system disk on the computer. One of the best programs for uninstalling applications is the free CCleaner utility.
Disable unnecessary programs and services from Windows autorun
There is a wonderful utility called msconfig, with its help you can speed up Windows boot. Although modern computers load the OS quickly, boot optimization can remove the black screen for a few seconds.
- Start - Run. In the window, enter msconfig.
- Services tab - here you can disable unnecessary services.
- Startup tab - to enable / disable programs at startup.
In Windows 10, startup items can be disabled through the Task Manager (Startup tab). The status column displays the status of the application.
We use a restore point to roll back the system on the computer and fix problems on the computer
It happens that it is impossible to identify the cause of an OS failure, removing drivers and programs that cause conflicts does not help: anyway, when the computer boots up, a black screen appears.
If the computer does not start, we use the previous Windows restore point
Using a bootable disk (Live CD) to fix errors and diagnose a black screen
When a black screen appears, it is advisable to check your computer and operating system for viruses. This can be done using a "live CD". We advise you to use to enter the system recovery mode. In addition to checking for viruses, livecd 4MRescueKit includes data recovery modules, file backup and a disk manager like PartitionMagic. Even if this does not help to get rid of the black screen of death, you can at least prepare for reinstalling the operating system or diagnose the health of the hard drive in this mode. The Live CD fixes problems regardless of version: it can be Windows or Linux.
4MRescueKit Download Kit Helps Eliminate Software Errors on Disk
Black screen during the Windows reinstallation phase
I get a black screen and a cursor, I reinstalled Windu and still I can't reinstall it until the end. After the first reboot, during the installation process, when booting Windows, a black screen and a cursor.
Solution to the problem.
- Try using a different installation disc or version of Windows.
- The reason for the black screen and interrupted download can be either software or hardware. For example, the hard disk contains bad sectors or a USB flash drive, or the disk from which Windows is being installed is damaged.
- Try installing the operating system on a different hard disk partition.
Viruses have damaged Windows system files
Many computer viruses are capable of deleting or damaging important system files. As a result, after loading Windows, a black screen appears, although the cursor may be displayed and react to your movements. Removing viruses does not always solve the problem, but you can try.
How to check the hard drive for viruses, if? You need a work computer to which you can attach a hard drive. After booting under Windows, install the free antivirus Dr Web CureIt. The CureIt utility contains up-to-date virus databases.
Video instruction:
Select the hard drive to scan and start the scanner.
If, after detecting viruses, a black screen appears when Windows starts up anyway, then you need to look for other reasons.
We write down the USB flash drive for recovery and reinstall Windows
After updating Windows 7 - a black screen in any mode: normal, safe - no difference. I tried to restore Windows through the installation disc - to no avail.
Answer... Install Windows 7 from scratch or immediately install Windows 10, thereby killing two birds with one stone: update and solve the problem with a black screen when loading Windows 7.
One of the best programs for writing Windows to a USB flash drive - Rufus... The utility is available in Russian, it is free and, as a rule, writes fail-safe USB sticks for installing Windows.
Worst thing that can happen: the hard drive is out of order
Finally, one of the most pessimistic outcomes. If you see a black screen and the cursor is still visible, then the hard drive is working. If there is nothing but a black screen, the OS does not boot, then it is quite possible that the computer does not see the hard drive and, accordingly, Windows does not boot. Following the link, you can familiarize yourself with the guides that will allow you to diagnose the hard drive and find out: is it possible to make repairs, restore data by loading the operating system, or is it better to go straight to the store and purchase a new HDD for a computer or laptop.
Summary... In this guide, I tried to remember and collect from the Internet the most complete list of problems due to which a black screen appears on a PC. The OS version does not really matter, Windows 8, "dozen" or even outdated XP. If none of the methods helped, something is not clear, or you have your own ways to solve this problem - please ask questions and add your ideas in the comments.
Answers to readers' questions
I have a black screen after loading Windows, I tried everything, but nothing helps: I turn on the computer - a black screen, and nothing can be done about it. The bottom line is that the black screen appears only after I update the drivers for the video card. If you put a standard VGA, then everything starts up and works fine.
Before that, I completely reinstalled Windu and it all started somehow unexpectedly with "nothing". How to fix black screen when loading windows?
Answer... One of the surest ways to resolve OS and driver conflicts on your computer is to go to the website of your video card manufacturer and download the latest drivers or stable ones, not in beta, to disk. When downloading, make sure to specify your operating system in the same bitness (32- or 64-bit). It is also possible that your video card is outdated and not supported by modern operating systems, in particular Windows 10.
If your laptop has a black screen, try updating the drivers
I have Windows 10 installed. When trying to restore the OS from a system image, it failed. Now a black screen with a flickering cursor in the upper left corner when turned on. All I can do is turn on the computer and enter the Bios.
Answer... If you only see a black screen and a cursor, it is a sure sign that the operating system cannot boot (you already understood the problem).
If the Recovery Console or Windows 10 installation disc does not help to roll back the OS to its original state or restore point, create or a new disc to recover or install the operating system from scratch.
Not a single folder opened, I decided to start it. A black screen with a cursor appeared on the laptop when Windows was turned on / started. I did everything according to your article, but the screen is still black. Help me please.
Answer... If, when starting windows, a black screen appears even after recovery, it makes sense to reinstall the operating system on your laptop in another way - for example, in the boot mode of a flash drive or disk. Since, according to your description of the problem, the cursor still appears on boot, this is a software error, not a hardware error.
An external box was connected via usb for formatting ext3 with PartitionMagic. After formatting, the laptop was restarted and there was no reboot, and a message appeared on the black screen: error loading operating system ... The laptop no longer boots, does not respond to any keys ... XP OS ... everything, there is a 2nd Windows 10 PC. In other words, the laptop works - but the screen is black.
Answer... Luckily, your laptop is dealing with a software glitch, not a hardware failure. All you need to do is reinstall the Windows operating system. After that, the black screen of death will no longer make itself felt. If your laptop has a floppy drive, use a bootable OS recovery disc. Otherwise, it will help you, it is not difficult to write it down, read the instructions on the link.
I have a black screen when I turn on my computer. Nothing appears on the monitor when I turn on the computer and the system unit is working. I did one trick: I pulled out the power, held down the power button for 5 seconds, released it, inserted the power cord, turned on the PC - everything worked fine. After 3 days it's the same, but this trick doesn't work. I think this is a wrong shutdown. I turned off the last time when some programs were still running (Windows 7 for me) and after loading the Desktop does not appear. What to do if the computer has a black screen?
Answer... You need to approach the problem in a comprehensive manner: to figure out whether the motherboard and the power supply unit are working correctly, whether all the wires are connected to those power connectors, whether the PC components are tightly connected to the sockets (for example, very often the "black screen of death" is associated with incorrect connection video cards). Perhaps the problem is still not hardware, but software (only it is not clear from your question whether Windows boots). In this case, reinstalling from a bootable disk or restoring in LiveCD mode will help.
Help me understand what's with the PC. I have Windows 7. After starting the startup, a black screen and a cursor appear, after which it is suggested to select the Windows 7 OS and the recommended boot or normal. After pressing them, the download starts and throws it back into the same settings. The same problem with booting in safe mode. Nothing further suggests, there is no window to enter explorer.exe.
Answer... If, when you try to boot Windows 7, a black screen and the cursor continues to appear, which mode you did not select, most likely Windows system files were deleted or changed. A clean reinstallation of the OS or recovery from the Windows 7 boot disk will help. In the boot menu, select “System Restore” and then use the Bootrec.exe utility. Further actions are described.
I have an AMD Radeon video card with 512 mb of memory, it did not pull new toys and I found on the Internet how to increase the memory of an integrated video card via bios. I changed some settings in the BIOS and installed 1 GB of memory, my PC rebooted and I looked at the characteristics of the video card and yes, in fact, the memory increased. Then I started playing games, it took about an hour and my mouse started to freeze, turn on and off itself, and then stopped working altogether, I decided to restart the PC and after that on my monitor I saw just a black picture with some number in the corner. The computer refused to turn on, after probably half an hour of clicking on the mouse and keyboard, a "welcome" appeared on the screen. The PC turned on, but the mouse did not work, I rebooted again - and again a very long black screen when the computer boots. What can it be and how can I get rid of it?
Answer... This is what overclocking a video card leads to. You need to go into BIOS and do a factory reset (set by default). Perhaps, it is because of the BIOS settings that Windows does not start.
You are still in luck: with such overclocking of the video card, problems with the temperature of the video card may arise, up to the failure of one of the components (for example, the processor).
In general, you cannot always trust such overclocking instructions. Even if it contains correct information, in the absence of proper skills, you can get not only a black screen, but also black smoke from the system unit :).
I don't know where it started, maybe after defragmenting the hard drive, after updating the drivers, etc. Every time, before Windows boots, a black screen is displayed for 10 minutes and only after that the welcome window appears. BIOS boots exactly at the beginning, pressed F2 to check the priority of the boot device in the BIOS. Also during a black screen, the console caret (bottom slash) sometimes appears. What causes a black screen when loading Windows?
Answer... In the BIOS, you can not only set the boot priority, but also disable unnecessary devices (for example, a floppy drive). However, this will not save the day.
Perhaps the reason lies in the fact that when Windows starts up, it tries to find the required library or load a non-existent component. Go to the startup menu and disable all unnecessary items. You can also disable unused Windows services through msconfig and remove unnecessary applications on the computer. In general, it is desirable to optimize the operation of the operating system and eliminate conflicts.
You can also analyze Windows boot phases using the built-in Event Log Viewer. This utility will show how long it takes to load each process when the OS starts.
If time permits, reinstall the OS. On modern computers, reinstalling takes less than half an hour, and this is a more rational way to solve the black screen problem than hours of troubleshooting. Sooner or later, any Windows operating system is overgrown with problems.
Black screen when booting Windows 10. This happened after installing the drivers from the driver pack. After the system starts, a black screen is displayed, while the cursor is visible, sounds from programs that have been opened in the browser (VK) are coming. It does not react to anything, the reboot did not help, it also does not enter the safe mode.
Answer... You can use a Windows 10 boot disk or flash drive, select a recovery mode and select a rollback point before installing the drivers. The black screen will disappear after booting Windows 10. You can enter Windows safe mode through the Windows installation disk; other OS boot modes are also available there.
If you can insert another video card into the motherboard, you can try it into the system and remove the drivers manually. Then change the video card to the old one - it should work.
I have Windows 7 on my computer. Everything was fine, but once after entering the bios password, there was no Windows boot icon, and the monitor turned off (went into power-saving mode), the f8 key does not work. I cannot enter bios, because the monitor does not work.
Answer... Try to reset the BIOS by removing the battery from the motherboard.
Let's go further. The power-saving mode will not work immediately after starting the computer; rather, the problem is related to one of the components. Check the connection of the video card to the motherboard, the video card to the monitor, etc.
If everything is in order with the BIOS, and Windows 7 does not boot, reinstall the OS. This seems to be the easiest method to get rid of the black screen.
Windows 7 32bit OS was installed. After changing to Windows 7 64bit, a black screen began to appear. When connected to a TV, everything works, everything shows, everything is fine. But he does not see through the vga-monitor and the screen is still black.
Answer... It is possible that the drivers for the monitor or video card were not installed in the 64-bit version. Check on the manufacturer's website if the monitor supports this OS. There is a suspicion that your particular vga monitor is not supported by this edition of Windows. Try to boot Windows in Safe Mode or with the "Enable low resolution video mode (640x480)" option.
I am using VirtualBox. Installed Linux, worked on it, then turned off the virtual machine. When I tried to launch, after loading, a black screen appears with an underscore at the top left. The laptop itself works, the virtual machine does not.
Answer... If you save the state on the virtual machine (Suspend), in principle, no problems should arise. If you turn off the virtual machine, then Linux tries to boot when you turn it on. Why a black screen with an underscore appears after a Linux reboot is a separate question. Check the key settings of the virtual machine. If the error persists, try installing Linux on Vmware Player.
I have such a problem. There is Windows 8.1, installed a third-party theme, decided to delete, deleted the entire themes folder from windows, although not all files could be deleted, well, that's okay, I rebooted the computer and after selecting the OS I have a black screen and, no, no, the cursor appears and disappears and bottom toolbar, tell me how to get rid of the black screen? There is no recovery point, no image, and no OS disk either.
Answer... If possible, find on the Internet a bootable USB Boot image or the like, write it to a USB flash drive. Find the Themes folder on the Internet or on disk and copy it with administrator rights to the original location from where you deleted the files.
Without the installation disc, you can hardly get rid of the black screen any other way.
When I turned on the computer, nothing appeared. the light shows that the camera is working and the computer is on, but the screen is zero. What is the problem - RAM or hard drive? How to check?
Answer... To diagnose the problem, it is advisable to recall previous events. Did the computer show any symptoms of a breakdown (hard disk noise), did you delete system files on the disk, etc. This will help narrow down the list of possible causes. Next - watch at what stage the black screen appears. If the initialization of the equipment is successful, then the matter is in the operating system - that is, Windows does not start. In this case, we advise you to reinstall the OS from a bootable USB flash drive or disk.
A fairly common situation - when you turn on the computer Windows won't boot and appears black screen (not to be confused with).
An unambiguous answer, why does a black screen appear on Windows It is impossible to give, since there can be many reasons - from a banal power outage (for example, the light was turned off), and you, unaware of it, press the computer power button in a rage, to more serious ones - failure (breakdown, malfunction) of the hardware a problem with the PC hardware (power supply, processor, motherboard, monitor, etc.).
If when you turn on the computer nothing happens at all - no noise of the cooler (fan) rotation is heard, the indicator lamps are off, then first determine whether the computer is powered. Check the outlet (with any household appliance), the correct connection of all power and screen cables. Perhaps the wire just came off, it is recommended to disconnect and reconnect them correctly, it will not take much time.
If you have followed the above steps, but when you turn on the computer a black screen appears, you can safely talk about a malfunction of the PC hardware. If your computer or laptop is still under warranty or you do not understand the hardware, then it is better to take it to the service center to specialists. Those who are not afraid of experiments can try to fix the cause of the black screen on their own, if they are lucky - save money on repairs.
To get started, completely disconnect the computer, disconnect all cables and wires, remove the side and front panels (depending on which case). Start small - take a closer look at the Power start button, it may just be broken.
Inspect the computer hardware and wires for traces of mechanical damage and short circuits - carbon deposits, soot, if necessary (if the PC is dusty) clean the computer from dust. You can read how to clean your computer yourself at home in.
Do not forget to check all connectors in which the video card, RAM and cables are installed. If you find a breakdown, you can save money and replace the hardware yourself or take it to a service.
The most common reasons for a black screen on a PC are a failure of the monitor and video card. For example, they "burned out" for me five years after the purchase, and what is strange within a month - first "vidyuha" and a month later the monitor "burned out". Probably the time has come - they have worked for 5 years ... and that's enough)).
In these cases, the computer starts up, Windows is loading (sound is heard from the speakers), but there is no image on the monitor. It is easy and simple to check - the monitor can be connected to another computer, laptop, or just to an outlet (if it is working properly, NO SIGNAL will appear). I just connected the TV to my computer (the second monitor) - there was an image on it.
To check the video card, this method is also suitable, if the problem is in the video card, then there will be no images on both displays (monitor-monitor, TV-monitor).
A black screen and freezing of the computer can appear even if the BIOS is incorrectly configured. You can read about the settings and restoration of BIOS by default on our website.
There are cases of freezing of a computer with inscriptions on the display with a black screen. Perhaps the mode will help " Last Known Good Configuration boot with working parameters"or" "and Windows System Restore, if not disabled for the purpose.
The program can fix some of the causes of the black screen. You can also reinstall the operating system if the black screen was caused by the software.
