When You Turn On Your Computer Black Screen What To Do
Hello everyone! If you see a black screen when you turn on the computer, then this is the first sign that some problems have occurred in its operation that do not allow the Windows operating system to function normally. There can be several reasons for this phenomenon; we list them:
- Incorrect shutdown of Windows;
- The computer does not see the hard drive;
- Damage to the interface cable for connecting the monitor or lack of contact;
- Not loading desktop;
- There is no Windows license;
- The components of the system unit do not work;
- Software problems, viruses, lack of drivers;
As you can see, there are a lot of reasons when a black screen appears when you turn on the computer, so we will analyze each of them individually and try to fix the problems yourself.
- Problems booting Windows
- Problems with the cable or monitor.
- Windows desktop does not load.
- Black screen when you turn on the computer. Windows is not licensed.
- Faulty system unit components.
- Problems with the graphics card or driver.
- To summarize.
Problems booting Windows
Probably the most common reason for a black screen to appear is a failure in loading the operating system. Very often it occurs when the system shuts down incorrectly or the boot area is damaged.
In most cases, this problem occurs when users suddenly turn off the power and the computer turns off at the most inopportune moment.
With this outcome, the user will see a black screen when you turn on the computer with options for loading the system.
Here, most often, it is enough to select the “Normal Windows boot” option and wait for the system to start.
If the system does not give you a window with boot options, then do the following:
- After you turn on the computer, you must press the “F8” key, the “Advanced boot options” window should appear;
- In this window, you can select three options “Safe Mode”. With it, you can boot the system and fix the problem that arose after an unexpected shutdown of the PC, incorrect installation of software or viruses;
- If you are sure that everything is fine with the computer, then select “Normal Download”
Problems with the cable or monitor.
Sometimes there are cases when the cable connecting the monitor to the system unit fails. In this case, it is necessary to inspect it for damage. Particular attention must be paid to the connectors. A fairly common reason is the bent antennae of the contacts on VGA cables.
To exclude a faulty cable, it will be enough to take the substitution and connect.
If everything is normal with the cable, then check the monitor. First, pay attention to the power indicator (a light on the monitor panel). If the indicator is on, then power is supplied to the monitor, if not, then we look at the power wires. Perhaps they are not connected to the network or some contact has gone.
If you can connect another monitor, then definitely use it.
Windows desktop does not load.
Another fairly common reason that the user sees a black screen when the computer is turned on is the non-loading desktop. The problem occurs after the computer is cured of viruses. At the same time, the system seems to be loading, but the desktop remains empty: no shortcuts, no folders, no taskbar. If you have a similar situation, then do the following:
- First of all, we launch the Windows task manager, for this we press the hotkey combination “Ctrl” “Shift” “Esc”;
- In the task manager window that opens, click on the “File” menu and select “Run a new task” in the list that appears;
- Next, in the window, enter the command “regedit” to start the registry editor;
- The “Windows Registry Editor” window will load, in it we will move along the path:
HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / WindowsNT / CurrentVersion / Winlogon
- In the “Winlogon” branch we are looking for the “Shell” key, this key should have the value “explorer.Exe”. If you see another value or even an empty field, then we prescribe the correct parameter and save the settings;
- After the manipulations are done, we restart the computer and rejoice that everything works as before.
Black screen when you turn on the computer. Windows is not licensed.
For most users, a black screen appears on the desktop after updating the operating system. This happens to users of a pirated, hacked version of Windows. At the same time, in the lower right corner, near the clock, you will see the inscription: “Your system is not genuine, get a license.”
If you encounter this problem, then you have two solutions:
- Reinstall the system, and after reinstalling disable the installation of all updates, but then you risk that your computer may be infected with a virus, such as Wanna Cry;
- Purchase a license for your product and sleep peacefully. After all, the computer will receive all the necessary patches and work more stably.
Unfortunately, no other way out of this situation has been given.
Faulty system unit components.
If the above tips did not help to fix the problem, then most likely there is a problem with one of the components of the system unit.
To begin with, you should open the system cover and inspect the components of the computer, it is possible to clean them from dust and dirt.
Also inspect the motherboard for swollen capacitors, perhaps the cause of all the troubles is in them. Then, most likely, you will need to replace the node, namely the motherboard or soldering of faulty elements.
Remove the graphics card from the system unit and clean all the pins. Perhaps over time, oxidation or dust has occurred.
Next, we check the connection of all wires, if the card requires additional power, then it must be connected.
RAM can also cause a black screen and a system failure to boot. If there are several memory modules, then we take everything out and try to connect one at a time and test the start of the computer. With a successful start of the system, we conclude that some memory bar does not work correctly, and change it to another.
Also, be sure to clean the contacts of all memory modules, maybe the reason is quite banal, there is no contact between the port of the motherboard and the RAM module.
Problems with the graphics card or driver.
In my practice, there were often cases when a black screen appeared when the computer was turned on due to a faulty card. Since many modern PCs are equipped with a discrete and integrated graphics adapter, you can simply connect the monitor to the integrated adapter and check whether the image appears on the screen.
A fairly common reason for failure of discrete adapters is overheating. By the way, if you are not aware of which adapter you have installed, then read the article. How to find out the card of your computer.
Rarely, the image on the screen refuses to appear due to improperly installed drivers. To eliminate this problem, download the latest driver for your card from the official website and install. Perhaps the problem will be solved by itself.
Today we have examined the solution to the problem when a black screen appears when you turn on the computer. I hope the tips described in this article help you identify the cause of the malfunction and fix it. The main thing is to act slowly and approach the matter meaningfully.
I do not want to be commonplace, but the so-called “black screen problem” when the operating system boots after turning on the computer. One of the most common problems owners of both desktop computers and laptops face. An operating system that does not boot or a hard disk model does not matter much when diagnosing a problem. On how to remove the black screen when loading Windows 7, Windows 10 on a computer and laptop, the reasons for the failure, we will describe further.
This manual will be supplemented, so do not hesitate to ask questions, I will clarify the technical aspects as much as possible and solve your problems with the black screen.
The most likely causes of a black screen when loading
First you need to list the most common problems that cause a black screen, after which the operating system does not load (in other words, when you turn on the computer, a black screen). In rare cases, after loading, the user sees not only a black screen, but also a cursor. Causes:
- Operating system conflict, which is why it cannot load the graphical environment normally.
- 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 crashes and does not load correctly (not in safe mode)
- Other hardware problems or system conflicts
- Windows cannot wake up
Starting Windows in safe mode on a computer
One of the most likely reasons why Windows or another operating system does not boot. 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 you turn on the laptop / PC, the conflict will make itself felt in an unpleasant way. In the form of a black screen. How to remove it?
Fortunately, Windows developers have provided the ability to safely enter the operating system, which is designed specifically to fix various compatibility issues. Entering safe mode, you can remove all problems on the computer, resolve conflicts, and then load Windows OS in normal mode.
So, to enter safe mode on your computer:
- Remove all media and devices from the computer that may affect the loading of Windows (flash drives, disks, etc.)
- Restart or turn on the computer, depending on its current state.
- To enter safe mode, hold down the F8 key during boot. If there are several operating systems on your PC (laptop or desktop), then select the appropriate one from the list and then hold down F8 again to switch to the safe boot mode for Windows.
Further, in the boot options in safe mode, you can select one of the items and solve the problems of a black screen on a laptop or desktop computer.
Problems with the monitor or accessories
The reason for the black screen may lie on the surface: the monitor does not work. This may be due to the fact that the contact between the monitor and the card has disappeared or the power cable is damaged / not plugged in. 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, a mechanical effect on the display. At the same time, you will see that there are obvious damage on the screen: scratches, broken pixels and so on.
In addition to the monitor, we advise you to explore the system unit. Check if the card is fixed in the corresponding socket of the motherboard, whether there is a voltage supply to all components of the PC. This should be done only if you have the skills to assemble / disassemble a computer / laptop.
Conflict resolution with driver, if the computer does not start, a black screen is displayed
An example of a similar problem:
If you think that the black screen problem may be related to the conflict of the card drivers on the computer or laptop, then:
- In the safe boot menu, select “Enable low resolution mode”.
- After successfully logging into your operating system account through the device manager or Control Panel, remove the conflicting ATI / NVIDIA driver.
- Restart your computer
- There may be a conflict between the drivers of the motherboard and the card. You need to try different combinations of drivers. In order not to reinstall Windows each time during experiments, create a restore point and, when a black screen appears, roll back to the previous restore control point.
- If the OS boots in the 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 website of the card manufacturer and download the latest version to your hard drive, try updating the driver again.
- If the black screen continues to appear, try the other solutions described in this guide. E.G. Delete “harmful” programs.
We remove programs that conflict and block OS loading at startup
In this case, the sequence of actions to resolve the problem will be approximately the same as in the above case. The only thing that in safe boot mode Windows you need to specify “Enable Safe Mode”. Next, in this boot mode, you need to go to the control panel and in the window “Programs and Features” Sort by application installation date. Analyze what you installed recently: it is possible that conflicting applications are the cause of the black screen and inadequate loading of Windows from the system drive on your computer. One of the best programs to uninstall applications. Free CCleaner utility.
Disable unnecessary programs and services from Windows startup
There is a wonderful utility msconfig, with its help you can speed up loading Windows. Although modern computers load the OS quickly, optimizing the download 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 boot.
In Windows 10, startup items can be disabled through the task manager (Startup tab). The status column displays the application status.
We use a recovery 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 the OS failure, uninstalling drivers and programs that cause conflicts does not help: anyway, when the computer boots up, a black screen appears.
What to do with the problem? Reinstall the operating system? If Windows is still loading when you turn on your computer, do not rush it “bury”. For starters, we recommend that you try to roll back the Windows operating system using the recovery point (you can do this by booting in safe mode). For more information on how to roll back the system, read the link.
If the computer does not start. Use the previous Windows restore point
Use boot disk (Live CD) to fix errors and diagnose black screen
When a black screen appears, it is advisable to check the computer and operating system for viruses. You can do this with “live cd”. We recommend that you use the 4MRescueKit boot disk to enter system recovery mode. In addition to the actual virus scan, livecd 4MRescueKit includes modules for data recovery, file backup and a disk manager like PartitionMagic. Even if this does not help get rid of the black screen of death, you can at least prepare for reinstalling the operating system or diagnose the hard drive in this mode. Live CD fixes problems regardless of version: it can be both Windows and Linux.
4MRescueKit Boot Kit Helps Eliminate Software Errors on a Disk
Black screen during the reinstallation of Windows
Solution to the problem.
- Try using a different installation disk or version of Windows.
- The reason for the appearance of a black screen and interruption of the 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 installed is damaged.
- Try installing the operating system on a different partition on the hard drive.
Viruses corrupted Windows system files
Many computer viruses can remove or corrupt important system files. As a result, after loading Windows, a black screen appears, although the cursor may be displayed and react to your movements. Not always removing viruses helps to solve the problem, but you can try.
How to check the hard drive for viruses if Windows does not boot? You need a working computer to which you can attach a hard drive. After booting under Windows, install the free Dr.Web CureIt antivirus. The CureIt utility contains current virus databases.
Select the hard drive to scan and run the scanner.
If after detecting viruses a black screen appears anyway during Windows startup, then you need to look for other reasons.
We write the recovery flash drive and reinstall Windows
Answer. Install Windows 7 from scratch or immediately install Windows 10, thereby killing two birds with one stone: upgrade and solve the black screen problem when loading Windows 7.
One of the most cardinal ways to bypass a black screen when loading. Reinstall a stable operating system. Once upon a time, to solve such problems, many of us used the installation CD / DVD disc (see above). After Window 7 came to the desktop PC market, the need for a drive gradually decreased, and today it is the most convenient way to install Windows. This is the creation of a bootable USB flash drive and recovery in boot mode from a usb drive. In general, read the practical guide on how to make a bootable windows 8 flash drive.
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 USB flash drives for installing Windows.
The worst thing that can happen: a hard drive crashes
Summary. In this guide, I tried to recall and collect from the Internet the most complete list of problems that cause a black screen on the PC. The version of the OS doesn’t really matter, Windows 8, “ten” is it or generally outdated XP. If none of the methods helped, something is unclear or you have your own ways to solve this problem. Please ask questions and add your ideas in the comments.
Frequently asked Questions
After entering the bios password, there is no Windows 7 boot icon, the monitor turned off (went into energy-saving mode), the f8 key does not work.
- Try to reset the BIOS by removing the battery from the motherboard.
- The energy-saving mode will not work immediately after starting the computer, rather the problem is associated with one of the components. Check the connection of the card from the motherboard, the card with the monitor, etc.
- If everything is fine with the BIOS, and Windows 7 does not boot, reinstall the OS. Apparently, this is the easiest method to get rid of the black screen.
After changing to Windows 7 from 32bit to 64bit, a black screen began to appear. When connected to a TV, everything works.
Perhaps, in the 64-bit version, drivers for the monitor or card are not installed. Check on the manufacturer’s website if the monitor supports this OS. There is a suspicion that specifically your vga-monitor is not supported by this edition of Windows. Try booting Windows in safe mode or with the option “Enabling low-resolution mode (640 × 480)”.
I use VirtualBox with Linux. Turned off the virtual machine, after loading. A black screen with a bottom underscore on the left.
If the state is maintained on the virtual machine (Suspend), in principle, no problems should arise. If you turned off the virtual machine, then Linux tries to boot when it is turned on. Why a black screen with an underline appears after rebooting Linux is a separate issue. Check the key settings for the virtual machine. If the error persists, try installing Linux on Vmware Player.
When I turned on the computer, nothing appeared. The camera works and the computer is turned on. What is the problem. RAM or hard disk?
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. Follow at what stage the black screen appears. If the hardware initialization is successful, then it means the operating system. That is, Windows does not start. In this case, we recommend reinstalling the OS from a bootable USB flash drive or disk.
I changed the card. I start the PC. There is a BIOS, and after that. Just a dark screen. Is it because of the drivers?
Maybe. Switch to Windows Safe Mode, uninstall the old drivers and install new ones. Then restart your PC. If it does not help, read the full article.
Answers to readers’ questions
I have a black screen after loading Windows, I tried everything, but nothing helps: I turn on the computer. Black screen and nothing to do with it. The bottom line is that a black screen appears only after I update the driver on the card. If you put the standard VGA, then everything starts and works fine.
Before that, I and Windu completely reinstalled and it all started somehow unexpectedly with “nothing”. How to fix a black screen when loading windows?
Answer. One of the surest ways to resolve OS and driver conflicts on a computer is to go to the website of the manufacturer of your card and download the latest drivers or stable ones, not in beta, to the disk. When downloading, make sure to indicate your operating system in the same bit capacity (32- or 64-bit). It is also possible that your card is outdated and is not supported by modern operating systems, in particular, Windows 10.
If the laptop is black, try updating the driver
I have Windows 10 installed. An error occurred while trying to restore the OS from the system image. 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 Bios.
Answer. If you see only a black screen and the cursor is a sure sign that the operating system cannot boot (you already understood the problem).
If the recovery console or the Windows 10 installation disc does not help to restore the OS to its original state or recovery point, create a bootable USB flash drive or a new drive to restore or install the operating system from scratch.
Not a single folder opened, I decided to start Windows System Restore. A black screen with a cursor appeared on the laptop when turning on / starting the Windows OS. I did everything according to your article, but the screen is still black. Help me please.
Answer. If, upon 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 USB flash drive or disk. Since, according to your description of the problem, the cursor still appears at boot time, this is a software error, not a hardware error.
An external box for formatting ext3 by PartitionMagic was connected via usb. After formatting was completed, the laptop restarted and there was no reboot, and a message appeared on the black screen: error loading operating system. The laptop no longer loads, does not respond to any keys. OS XP. How to be, almost everything is on it, there is a 2nd PC with Windows 10. In other words, the laptop is working. But the screen is black.
Answer. Fortunately, your laptop is dealing with a software failure rather than 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 drive, use a boot disk to restore the OS. Otherwise, a bootable USB flash drive will help you, it’s easy to record it, read the instructions on the link.
I have a black screen when I turn on the 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, pressed the power button for 5 seconds, released it, inserted the power cord, turned on the PC. Everything worked fine. After 3 days, the same thing, but this trick does not work. I think that it is for the wrong shutdown. I turned off the last time when some of my programs were still running (I have Windows 7) 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: to figure out whether the motherboard and the power supply in general are working correctly, whether all the wires are connected to those power connectors, whether the components of the PC are tightly connected to the sockets (for example, very often the “black screen of death” is connected with the wrong connection cards). Perhaps the problem is still not hardware, but software (it’s just not clear from your question whether Windows boots). In this case, reinstalling from the boot disk or restoring in LiveCD mode will help.
Help understand what is from the PC. I have Windows 7. After the start of the launch, a black screen and cursor appear, after which it is suggested to select Windows 7 and the recommended download or normal. After they are pressed, the download starts and throws it back into the same settings. The same problem with the download in safe mode. It offers nothing further, there is no window to enter explorer.Exe.
Answer. If, while trying to boot Windows 7, a black screen and the cursor continues to appear, which mode you have not been selected. Most likely, Windows system files have been 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 here.
I have an AMD Radeon graphics 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 card through 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 card and yes the memory actually increased. Then I started playing games, about an hour passed and my mouse started to hang up, turned on and off myself, and then it stopped working at all, 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, probably after half an hour clicks on the mouse and keyboard appeared on the screen “Welcome”. The PC turned on, but the mouse did not work, I rebooted again. And again a very long black screen when you boot the computer. What can it be and how can I get rid of it?
Answer. That’s what overclocking a card leads to. You need to go into the BIOS and reset to factory settings (set by default). Perhaps it is because of the BIOS settings that Windows does not start.
You are still lucky: with such overclocking of the card, problems with the temperature of the card can occur, 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 the 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 after what started, maybe after defragmenting the hard drive, after updating Windows, etc. Each time, before loading Windows, a black screen is displayed for 10 minutes and only after that a welcome window appears. The BIOS booted exactly at the beginning, pressed F2 to check the priority of the boot device in the BIOS. Also, during a black screen, the console carriage sometimes appears (bottom slash). What can cause 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 drive). However, this will not save the situation.
Perhaps the reason lies in the fact that when you boot Windows is trying to find the right library or load a nonexistent 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 your computer. In general, it is desirable to optimize the operation of the operating system and resolve conflicts.
You can also analyze the steps involved in loading Windows through the built-in tool. “View event logs”. 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 no more than half an hour, and this is a more rational way to solve the black screen problem than a long-term troubleshooting. Sooner or later, any Windows OS has problems.
I have such a problem. Windows 8.1 is installed, installed a third-party theme, decided to delete, deleted the entire themes folder from windows, although not all files could be deleted, well, ok, I rebooted the computer and after choosing the OS I have a black screen and, no, the cursor appears and disappears bottom toolbar, tell me how to get rid of the black screen? There is no recovery point, no image either, well, no disk with OS either.
Answer. If possible, search the Internet for a bootable USB Boot image, etc., write to a USB flash drive. Find the Themes folder on the Internet or on the disk and with administrator rights copy it to the previous place from where you deleted the files.
Without the installation disk, you can hardly get rid of the black screen in a different way.
Good afternoon! In the evening, the computer crashed. In the morning I turned 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. Turned off the computer, already touched all the wires. I turned on the black screen, several times I turn it on and off, the black screen is unchanged. Now I put the Windows disk, the system unit buzzed, I heard that it was starting and still a black screen. What should I do next?
It was 8.1, everything just flew, the system was completely on ssd, then I had the urge to reinstall win 8.1 on win 10 after the permutation, for a couple of days everything was fine, now when I start the screen is black and the cursor hangs 3-4 minutes after the Windows slowly and with glitches but everything it starts
At startup, a black screen. The indicators are all on, I tried to just restart, the first time it worked, but then again the black screen. Connected to a TV, everything worked well, what’s the problem?
My Windows 7 boots normally 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, means that there will always be a black screen. But still after that, Windows 7 boots up. As evidenced by the welcome sound of Windows 7, but the screen still remains black and the cursor is not visible. To turn off, you have to press a button on the system unit. The card drivers have been updated to the latest version from the manufacturer’s website. System recovery does not work. Viruses and malware removed. How can I remove a black screen?
During the installation of drivers AMD dramatically lost brightness. Rebooted, the boot selection menu is turned on. When turned on normally, the brightness is very low, you can see something only with the help of a flashlight. The brightness is standard, and the screen is dark. OS Windows 7. Please tell me what to do.
I have Windows 8 installed at work. Well, a couple of small files. It opens the file for a long time. And generally it takes a long time to load. In another office on my computer, 8.
