Today's article is devoted to solving a rather popular problem in which the usual start of a computer with the installed Windows 7 operating system is impossible. The disease looks like this:
the user presses the computer power button, after which the equipment starts loading the operating system. This process takes place without any problems and ... nothing happens: there is no usual screen for selecting users (if it was turned on and several people are registered in the system), the desktop that should have been loaded does not start, there are no inscriptions on the computer screen and hints indicating a solution to the problem - only a black screen.
Usually, when the Windows 7 system boots successfully, an inscription appears "Welcome" but in this case nothing happens. I agree that the situation looks terrible, but do not rush to call the wizard or reinstall Windows, because the solution to this problem is not as difficult as it seems at first glance.
Let's move from words to deeds
The first situation. The operating system boots successfully, but no further login occurs, instead a black screen appears. Only the mouse cursor moves on the screen, with which you can inconsolably search for shortcuts in order to click on them. The problem is related to the system file "explorer.exe", which could not boot in the usual mode (or did not start at all). Perhaps the problem lies in the registry entries and does not affect the hardware (which is most preferable).
Situation two. At the stage of loading (starting) Windows 7, an error message appears - the inscription "NTLDR is missing" in white letters on a black screen. The case is also quite common. The reason for this is a corrupted Windows 7 bootloader. Treatment - recover corrupted files.
I want to note right away that we do not need third-party software to solve problems, we will perform all the manipulations using standard Windows tools.
Let's analyze the first situation
Right-click on the "Winlogon" section, then select the "Create" item, in the menu that opens, select "String parameter"... Enter the name "Shell". We double-click on the newly created “Shell” parameter (or press the right mouse button and select “Change”), enter the word “explorer.exe” in the “Value” field. Click "OK" and reboot the system. If the problem is resolved after restarting and Windows 7 started successfully, then everything was done correctly. 
Sometimes, Microsoft OS users face a problem when after booting Windows only black screen and cursor mice. The symptom is quite well-known - the system process "explorer.exe" cannot start. There may be several reasons: a virus or vice versa - antivirus (Avast), problems with the hard drive, etc. Quite often fix black screen on startup can be done in a minute without any third-party utilities.
As already mentioned in the title - the reason for this behavior is process startup error, which is responsible, among other things, for displaying the desktop, its elements and the panel with the "Start" button. In this recovery guide, we'll look at two popular reasons why when Windows boots up, a black screen and a cursor are visible instead of the desktop. One of the reasons in some cases is the popular Avast antivirus, which, for reasons known only to him, blocks “ explorer.exe". In the second case, you will have to slightly edit the system registry. In both situations Windows is working again very easy.
Avast is the culprit behind the black screen on Windows startup.
So after Windows booted, but on the screen there is only a black "Malevich square" on which the "abstract cockroach" - the mouse cursor is running, do the following:
- 1. Press the world famous combination of buttons " Ctrl + Alt + Del"And select" Start Task Manager "from the list.
- 2. After the Task Manager window appears, find in the list of processes " avast"(The" Processes "tab) and from the context menu (right-click on the process) select" Open file location ".
- 3. You will see a window with a folder where the Avast antivirus is installed. Find the file "AvastUI" in it and run it (double click or "Enter"). The main antivirus window should open.
- 4. Go to the top tab " Security", In the list on the left, select" Antivirus", And among the menu items that appear, click on" Behavior screen».
- 5. Open display settings and add to reliable processes « c: \ windows \ explorer.exe"(Use the" Browse "button). We confirm our actions with the "OK" button.
- 6. Restart your computer: again click " Ctrl + Alt + Del»And find the corresponding icon on the screen that appears.
If the Avast antivirus was the culprit, then after performing the steps from the instructions for solving the problem black screen and mouse cursor on Windows startup- The next boot of the operating system should be successful. It is possible that the problem has already been solved by Avast's developers, but the process of adding the program to the "trusted" ones can still come in handy. Moreover, it is not known how the antivirus will react to the upcoming release Windows 10.
If you use another antivirus, then try to find in its settings a similar item to create a list of "trusted", "reliable", "ignored", etc. applications that should not be scanned by this antivirus. If the antivirus is to blame, then black screen with cursor at boot Shouldn't bother you anymore. The defender, who responds so inadequately to popular programs, is likely to receive a corresponding update in the next few days (or maybe hours). It is quite possible that it will be received automatically if there is an Internet connection and a configured function for updating the antivirus via the Internet. Otherwise, it is recommended to download the updated version from the official website.
Not always mistakes and similar situations on Windows startup caused by antivirus. There may be hardware problems. The review was recently published. But further we will consider the solution when, in the current situation ( only the mouse cursor is on the screen) Incorrect Windows registry settings are to blame.
What if only a black screen and mouse are visible when Windows starts? We correct the system registry.
The first step is exactly the same as in the case of antivirus: you need to open , use it to run registry editor and check / fix a couple of Windows registry values.
- 1. In a state black screen press the world-famous combination of buttons "Ctrl + Alt + Del" and select "Start Task Manager" from the list.
- 2. After the Task Manager window appears in the top menu "File" select "New task (Run) ...". The "Create a new task" window will appear. In the "Open" field, enter the command "" (without quotes). The Registry Editor window will open.
- 3. In left side windows go to the section (something like "folders" in explorer) with the name " HKEY_LOCAL_MACHINE". Expand it and go to the subsection " SOFTWARE". In the same way, get to the section " HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon».
- 4. In the right part of the window you will see a list of parameters. Find the parameter named " Shell". Its meaning there should be a line "explorer.exe"... If this is not the case, then after double-clicking on it, set the specified value. In the event that the "Shell" parameter is absent at all, then create it by selecting "New" - "String parameter" from the context menu of the "Logon" section. Specify the name of the new parameter ("Shell") and then double-click to set the value ("explorer.exe").
- 5. As in point 3, go to the section " HKEY_CURRENT_USER \ Software \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon". Here is the right side should not contain the "Shell" parameter. If there is one, then it follows remove it via the context menu or by pressing the "Delete" button on the keyboard.
The above two methods will help you restore Windows if at startup black screen and mouse cursor... Changing the "Shell" parameter often indicates that a computer has been infected by a virus. It is quite possible that it has already been neutralized by the installed antivirus, but traces of its activity could have remained in the system (change to "Shell").
Fortunately for most users, only a few are faced with the problem I want to describe today. We are talking about the so-called black screen, when when the computer boots up, the image remains black and you cannot do anything at the same time.
The most important thing in this case is not to panic, as some persons do, because this problem can be fixed in 99% of cases and it is not at all as difficult as you might think. Follow my simple tips and hopefully you will succeed.
First solution
I'll start with the simplest and most logical solution - restarting the computer. Yes, oddly enough, but it is this extremely simple operation that often helps to correct most errors.
If it does not help, then after booting the system, try pressing ALT + CTRL + DELETE or CTRL + SHIFT + ESC. By doing so, you can. In it, run "File" - "New task" - explorer.exe. If after that the desktop is launched, it means that the problem is software, which must be tried to be solved. In the meantime, you will have to use the PC only in this way.
Reinstalling the video adapter drivers
I will say right away that reinstalling the drivers for a video card is possible only if the operating system itself is loaded and, in addition to a black screen, you have the opportunity to use it.
Theoretically, a problem with the drivers may take place (they are outdated and simply do not fully function), so go to the official website of your video card manufacturer and download the latest drivers for the device, then run the file and follow the instructions.
You can also update the driver. To do this, go to the task manager ("Computer" - "Properties" - "Device Manager"), find your video adapter, move the mouse cursor over it, right-click and select "Update drivers". Then follow the instructions on the system.
Editing the registry
The next possible option is problems in the operation of the registry, as a result of which it will be necessary to fix some files. This is not as difficult as it seems.
So, we boot the computer and see a black screen. Launch the task manager again and enter explorer.exe in the "New task" item. Thus, the desktop appeared in front of your eyes. Perfectly.
Now you need to start the registry editor. To do this, click on the "Start" button and in the "Find programs and files" column enter the word regedit.
Then press Enter and the editor will start. You must follow the following path: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon. Here you will see the names of the parameters. Find the parameter named Shell among them. Its value should be as follows: explorer.exe.
We use the AVZ utility
And now I will tell you about one of the simplest and at the same time effective ways that will surely help you to cope with the difficulty.
There is such a utility called AVZ. It cannot be said that it fought well against viruses, but it copes well with various SpyWare, AdWare, BackDoor, Dialer and other Trojans. And it also has a host of various additional properties that you may need at any moment.
You need to download AVZ from the official site and run.
Select "File" - "System Restore".
Then check the box next to "Restore the Explorer launch key", then click on the "Perform marked operations" button. Everything, nothing more is required from you.
System restore to an earlier date
In order to restore the system, it is recommended to enter safe mode. This is done simply: when loading the operating system, you need to press the F8 key (in other cases, other options may be used, which I already wrote about in one of the pages). If you have one operating system installed, then the download will start immediately, but if there are several, then you will be given a choice to launch the desired axis.
You will see a selection of additional options, like mine on. Select "Safe Mode" and press Enter.
When the operating system is loaded, go to "Start", select "System Restore" and click "Next". Then select, on the date of creation of which your system was functioning normally and click "Finish".
We scan the system for viruses
Yes, it is viruses and Trojans that can become the main cause of problems, so do not forget to scan your system for malicious files, as I literally told you.
Any questions related to this problem, you can ask using comments.
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 laptops. The operating system that won't boot or the hard drive model is not very important in diagnosing the problem. How to remove the black screen when booting Windows 7, on a computer and laptop, the reasons for the failure, we will tell below.
This guide will be supplemented, so do not hesitate to ask questions, I will clarify technical points as much as possible and solve your black screen problems.
Most likely causes of a black screen on boot
First, it is necessary 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. Causes:
- The operating system is in conflict, as a result of which it cannot load the graphical environment normally.
- Video driver problem (incompatibility with the current operating system: for example, Windows 10 or Windows 7, up to XP)
- Failed hard drive on a computer or laptop
- Windows OS 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 boot 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 to log on to 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 of 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. In this case, 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 is displayed
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 the conflict of the video card drivers on the computer or laptop, then:
- From the Secure Boot menu, select Enable Low-Resolution Video.
- After successfully logging into the operating system account through Device Manager or Control Panel, uninstall the conflicting ATI / NVIDIA video driver.
- Reboot your computer
- There may be a conflict between the drivers of the motherboard and the video card. 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 related to 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.
We remove programs that conflict and block the OS loading at 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 reason for 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. Enter msconfig in the window.
- 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 recommend using the 4MRescueKit boot disk to enter the system recovery mode. In addition to actually 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 I still can't reinstall it until the end. After the first reboot, during the installation process, when Windows boots up, there is a black screen and a cursor.
Solution.
- Try using a different installation disc or version of Windows.
- The reason for the black screen and interrupted download can be both software and 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 partition on your hard drive.
Viruses have damaged Windows system files
Many computer viruses are capable of deleting or damaging important system files. As a result, after loading Windows OS a black screen appears, although the cursor can be displayed and react to your movements. Removing viruses does not always solve the problem, but you can try.
How to check your hard drive for viruses if Windows won't boot? 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: A Hard Drive Failed
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 conflicts between OS and drivers 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 crashed. 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, this is a sure sign that the operating system cannot boot (you already figured out 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 either a new disc to restore 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 at 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, it does not respond to any keys ... XP OS ... how to be, it practically that's it, 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 for 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 comprehensively: figure out whether the motherboard and the power supply unit are working properly, 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 from your question it is not clear 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 proposed 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 loading in safe mode. Suggests nothing further, 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 the 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 began 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. 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, it is not always possible to 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 what it started after, 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 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 much time it takes to load each process when the OS starts.
If time permits, reinstall the OS. On modern computers, reinstallation 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.
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 can not go into 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 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 (Suspend) on the virtual machine, 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 a problem like this. 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 restore 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 a disk and copy it with administrator rights to the original location from where you deleted the files.
Without an 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 turned on, but on the screen it 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.
Good day! In the evening, the computer froze. In the morning I turned it on on the screen - you need to restore the device, error 0x00000e9. I tried to restore through the input and the F8 button, as indicated, there were no changes on the screen. I turned off the computer and touched all the wires. I turned on the black screen, I turned it on several times, everything was unchanged, the black screen. Now I put the Windows disk, the system unit buzzed, you can hear that it is starting and still a black screen. What should I do next?

My Windows 7 boots normally at first. But if you turn off the computer and turn it on again, not after 10 minutes, but earlier, then a black screen appears without a cursor. At the same time, the monitor light flashes, which, as I noticed, indicates that there will be a black screen all the time. But still, after that Windows 7 boots - as evidenced by the Windows 7 welcome sound, but the screen still remains black and the cursor is not visible. To turn it off, you have to press a button on the system unit. I have updated my video card drivers to the latest version from the manufacturer's website. System Restore does not work.

I have Windows 8 installed at work empty. Well, a couple of small files. Opens the file for a long time. And in general it takes a long time to load.

Hello, there was such a situation. The Lenovo tablet stopped working, I press the power button, the screen does not respond, but the backlight is visible.

What could it be and how can I fix it?
A black screen when the computer or laptop boots up indicates a serious software or hardware problem. In this case, the fan on the processor cooling system may rotate and the hard disk load indicator light up. A significant amount of time and nervous energy is usually spent on solving such problems. In this article, we'll talk about the causes of the crash and how to fix 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 about the absence of loading the GUI of the operating system. The Explorer.exe file ( "Conductor"). Startup error "Explorer" may arise due to its blocking by viruses or antivirus software (this is quite possible in pirated copies of Windows - there have been cases), as well as due to banal damage by the same malware, user hands, or incorrect updates.
In this situation, you can do the following:
Option 2: Boot Disk
Such an error occurs due to a software failure or malfunction of the media itself or the port to which it is connected. Also, this can 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 is simply not included in the work.
The following steps will help you solve the problem:
- System restore with a preliminary attempt to boot into "Safe Mode"... This method is suitable in case of a failure in the operation of drivers and other programs.
- Checks the list of devices in the BIOS and their boot order. Some user actions can lead to disruption of the media queue and even to the removal of the desired disk from the list.
- Checking the performance of the "hard" 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 OS versions.
Option 3: Recovery Screen
This screen appears when the system cannot boot itself. This could be due to a crash, unexpected power outage, or incorrect actions to update, restore, or modify the system files responsible for booting. It can also be a virus attack directed at 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:
- Attempt to run the last known good configuration, if possible.
- If it doesn't work, then it's worth trying "Safe mode", it is possible that some programs, drivers or antivirus are preventing the download. If the download was successful (or not very well), then you need to perform a "rollback" or restore (see below).
- To start the recovery environment, select the appropriate menu item. If it is not there, you need to restart the computer and press the key at the next boot F8... If after that the item does not appear, then only the installation disk or USB flash drive with Windows will help.
- When booting from the installation media at the startup stage, you must select the mode "System Restore".
- The program will scan the disks for installed operating systems and, possibly, offer to make changes to the boot parameters. If this happens, then you must press the button Fix and Restart.
- In the event that it will not be offered to automatically correct errors, you need to select a system in the list (most often it will be one) and click " Further".
- You can try to select the first item in the console - "Startup recovery" and wait for the results, but in most cases this does not work (but worth a try).
- The second point is what we need. This function is responsible for finding restore points and rolling back the OS to previous states.
- The recovery utility will start, in which you need to click "Further".
- Here you need to determine after what actions the download failed. After that, select the appropriate restore point and click again "Further"... Do not forget to check the box next to the item Show other restore points- this can provide additional scope for choice.
- In the next window, click "Ready" and wait for the end of the process.
Unfortunately, this is all you can do to restore your system boot. Further, only reinstallation will help. In order not to get into such a situation and not to lose important files, make regular backups and create restore points before each installation of drivers and programs.

Conclusion
Thus, we have analyzed several options for the appearance of a black screen when loading the operating system. Successful recovery 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, as well as remember about ways to protect yourself from this kind of trouble.
