Computer won't turn on black screen and blinking. Black screen when loading Windows: what to do if the computer does not turn on. What to do if when you turn on the laptop, a black screen and a cursor

  • 21.11.2020

Sometimes, when turning on the computer, users encounter an unpleasant phenomenon: instead of loading the operating system, it displays black screen, which prompts you to select one of the additional options for downloading Windows xp, 7, 8, 10.

A black screen is a sure sign of system problems that can negatively affect the safety of information and the operation of the computer. But there is no need to panic and reinstall the system. Such a problem can be solved independently, spending a minimum of time and money. In this article, we will understand what causes the black screen and how to get rid of it.

Possible Causes of a Black Screen During Windows Boot

The main reason that causes a black screen is the wrong shutdown of the computer. Some users after work simply pull the cord out of the socket, which is absolutely impossible to do. After that, a variety of software errors and problems occur, causing a black screen to appear the next time the computer is turned on.

Although the fault of the user may not be present. For example, if there is a sudden power outage, and there is no uninterruptible power supply, the personal computer simply cannot shut down properly. And the next inclusion will necessarily entail a black screen.

The presence of viruses in the computer

Malicious software often causes system errors, up to the point that the computer refuses to boot normally. Therefore, it is recommended that you regularly check for viruses using verified ones. Also, you can not run unknown files from the Internet, which may contain a worm or a Trojan.

Bad contacts

The personal computer can turn on as usual, notifying the user with a squeak of the system unit, and the monitor does not show any signs of operation. In such a situation, it is advisable to check the performance of the monitor.

First you need to make sure that the monitor cable is connected to the system unit. If the day before the computer was moved to another room, then the connector contacts could simply move away. You also need to check the cable for damage. In some places, it is able to bend during use and break off inside.

Then you need to turn on the monitor separately from the PC. If it displays a message about the absence of a signal, then the problem is quite different. We need to move on, sorting through the probable causes of the black screen.

System failure

A black screen often indicates a system failure. In this case, the user is provided with several options for loading the operating system. To bring up the selection menu, you need to press the F8 key immediately after turning on the computer. Then select " safe mode» using the arrows and press « Enter» to confirm.

It is the “safe mode” that rescues the user in cases where the computer is infected with malware and cannot boot correctly. By selecting this mode, you will be able to enter the operating system and troubleshoot various problems.

Interestingly, "safe mode" has several options:

  1. First on the list safe mode" means running the minimum number of services and applications necessary for the operation of the operating system without network access.
  2. « Safe Mode Loading Network Drivers' comes second on the list. Unlike the previous one, it allows the user to freely access the Internet.
  3. Third on the list safe mode with command line support» to manage the operating system. This item is usually selected by network administrators.

If “safe mode” allowed you to boot and the monitor displayed the desktop, then the black screen problem was caused by a software glitch. It is possible that software with errors was recently installed on the computer, which caused the black screen to appear. It is recommended that you simply uninstall such a program or driver.

Another useful feature of "safe mode" is computer scanning. It allows you to find malicious program codes, both among installed applications and in the system registry.

Missing items on the desktop

Sometimes, after successfully removing virus programs, the black screen stops appearing, but another problem occurs that characterizes a blank desktop. After loading the operating system, neither shortcuts nor the Start menu are displayed. But even this problem is easily fixed if you follow the instructions below exactly.

  • 1. First you need to press the key combination " Ctrl + Shift + Esc' to open Task Manager.
  • 2. Then, in the task manager, go to the first tab "applications" at the top. Next, you have to click on the "new task" button. A small window will appear. For windows 10, you need to click " File» and select "Start a new task«.

  • 3. Now it remains to enter the command " regedit» and press « OK" to get into the registry of the operating system.

When the registry window opens, in it you need to go to the following path:

HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/WindowsNT/CurrentVersion/Winlogn (in windows 20 - Winlogon)/

There is a "Shell" parameter in the directory. The only value that guarantees stable operation of the system is “explorer.exe”. If the value differs from the above or is not present at all, it must be changed to the correct one. After the steps are completed, the computer will successfully display shortcuts on the desktop and open the Start menu.

Task Manager and other features blocked

Some malware is able to block the task manager and the user is unable to open it. Also, "safe mode" does not start. This problem has an interesting solution - opening the system recovery partition. To do this, you can use the "sticky keys" function.

  • To display the "Sticky Keys" window, just press the "Shift" key five times in a row at short intervals. In the window that opens, click on the " Yes“, located at the bottom to get into the center of accessibility.

  • There is a search bar in the Ease of Access Center. You need to enter the query " Task Manager» and press search.

  • Next, you need to follow the link " system" to get into the computer settings.

  • In the left column there is a "system protection" option, which you must select and click on it.


It remains to select a system restore point. After that, the task manager will work.

Problems with the video adapter or drivers

The cause of the black screen can also be incorrect drivers responsible for video processing. Various anomalies appear on the monitor or it refuses to work at all. The solution to the problem is to completely reinstall the video adapter control programs (drivers) and check the performance of the adapter itself.

Windows is not licensed

If a pirated copy of the operating system is installed on a personal computer, then after downloading the updates and connecting to the server, a black screen is likely to appear, in the corner of which a corresponding notification is displayed. You just need to purchase a license or reinstall Windows.

The presence of mechanical damage to PC components

If the above methods for eliminating the black screen did not help, then the problem lies in the system unit. Some electronic components fail, preventing the image from being displayed on the monitor. It is necessary to carefully inspect all internal parts to determine the nature of the malfunction.

First of all, the wires are subject to visual inspection. They must be intact and without damage to the braid. It is also important to make sure that the ports and various connectors are in good condition. For some users, dirt gets into the connectors, especially if you do not monitor the state of the computer for a long time. In turn, dirt causes a lack of contact.

Before troubleshooting, be sure to turn off the power to the computer and carefully unscrew the cover of the system unit. Then examine the appearance of the parts on the motherboard and video card. If they are covered with a thick layer of dust, carefully remove the dirt. Before this procedure, it is recommended to read the special instructions.

Next, you should check the safety of the wires and cables connecting the various elements of the computer. The surface of the cables must be free of flaws and other damage. It is required to make sure that they are connected not a stretch.

Quite rarely, the cause of a black screen lies in the failure of RAM modules. To verify this assumption, you need to remove all modules and check their health. After a thorough cleaning of the contacts of the slats, everything should work. It is also recommended to check the CMOS battery that is installed on the motherboard and replace if necessary.

The above steps will surely help to determine the cause of the black screen and fix it without the help of a service center employee.

After all, most often a black screen occurs after improper installation of drivers and an operating system failure. In these cases, it is enough to remove viruses or reinstall the applications responsible for the video adapter. If the screen does not work at all, then the reason lies in the technical problems associated with the inoperability of any component of the computer.

For example, if serious problems are found during the inspection of the motherboard (swollen capacitors, broken tracks or broken cables), then it would be appropriate to contact the repair shop specialists. It is not recommended to fix these problems on your own, because the average user does not have the necessary tools and skills.

Thus, the causes of a black screen can be very diverse. In our practice, we have come across two interesting cases when customers brought their personal computers for repair.

The main difficulty in repairing an unfamiliar computer is not knowing how the owner treated it. For example, one hostess decorated the system unit with fridge magnets, as a result of which some internal components became unusable.

Of course, the cases described may not always help to understand the causes of the breakdown. But on the other hand, they clearly show that even a trifle can seriously disrupt the performance of such a complex device as a personal computer. In most cases, the culprit was dirt particles that got on the tracks of the board and inside the video card. Which subsequently caused the black screen displayed when the computer was turned on.

In the cases described, by dirt particles we mean ordinary dust contained in the air. Over time, it accumulates inside the PC and interferes with its normal functioning. Foreign particles can be removed with a cloth soaked in alcohol or with a miniature vacuum cleaner. Then turn on the PC and make sure the cleaning result is positive.

A manufacturing defect that occurred during the manufacture of any computer component can also cause a black screen. We encountered several dozen video cards intended for installation in terminal clients. Testing has shown that most video cards are not operational. After a detailed visual inspection, our experts found that the board has a small plaque, of unknown origin, in the corner.

You can clearly see some kind of foreign substance adhering directly to the tracks of the board. Our experts decided that the problem of the malfunction could lie precisely in it, so it was decided to repeat the cleaning steps. It is likely that this substance prevents the PC from booting normally.

For cleaning, a cloth soaked in an alcohol solution was used. All paths were carefully wiped from a strange raid. A small cleaning difficulty was in the small protruding parts - it was important not to damage them.

After installing the video cards in personal computers, everything worked as usual. This case shows that many problems have a simple and effective solution that can be carried out in a short time and without significant expenditure of money.

Conclusion

The article examined the most common causes of a black screen on personal computers. Many of them can be solved independently, without resorting to the help of specialists. In particular, this is an improper shutdown of the computer, which caused an incorrect boot, as well as infection of the system with viruses. It is enough to boot into "safe mode" and solve the black screen problem.

Especially for this, we have listed all the possible actions designed to clean up malware. You just need to carefully read the above instructions and follow the instructions exactly. In case of difficulties, it is recommended to contact a specialized computer forum and discuss the problem with experienced users who are competent in this matter.

However, if the black screen arose due to internal computer problems (faulty parts, damaged tracks or mechanical stress), then it is better to take the system unit to the workshop and get qualified help. The wizard will carry out a comprehensive diagnosis of the motherboard and fix problems. If the computer is under warranty, then you can use this service for free.

A black screen on a computer monitor immediately after turning it on is not an uncommon situation. What should I do if a black screen appears when I turn on the computer, and the system does not respond to any user actions? We will try to answer this and other related questions. To begin with, we list a number of reasons that can provoke such PC behavior during boot:

  • Virus attack on the operating system.
  • System software failure.
  • The connection between the monitor and the computer is broken.
  • Black screen due to hardware failure.

This list exhausts most of the cases of a black screen during the computer boot process. The user only needs to correctly localize the cause and follow our instructions.

If something does not work, there is no need to panic and twitch - you need to do everything consistently and accurately. Computer crashes when you turn it on are a fairly common thing, in extremely rare cases they indicate that it is time to take your computer to a landfill, usually everything is much simpler. So, after rebooting, we have a black screen on which nothing is visible, there is no cursor, Windows does not load, and we sit stupidly staring at the monitor, not understanding what to do next.

Lost monitor contacts

The first step is to check if the display is connected to the computer. You could accidentally touch the cable connecting the monitor and the computer, you could inadvertently connect the monitor when moving the computer to a new location. But what other reasons could there be? After a black screen appears, check the plug on the back of the system unit - it is quite possible that it has come off. It will be necessary to unscrew it from the connector, check whether all the contacts are safe and sound - whether they are bent or not broken off at all. Then gently but firmly insert the plug into the socket and screw both screws firmly. If after rebooting the black screen reappears and nothing happens on the screen, try disconnecting the monitor from the computer and turning it on as an independent device. When turned on, it should give a notification that there is no video signal. In the absence of such a message, carry the monitor in for repair - the problem is in it.

It should be clear to the reader by now that this method is not suitable for laptops. It is impossible and unnecessary to do anything with them. What to do when the monitor is working, but the black screen still appears when you turn it on? Here our actions will depend on the type of black screen. Let's say a menu appears in front of us on a black background, as in the figure below:

Then we are talking about problems of a slightly different type than when the monitor malfunctions.

System software failure

If the Windows operating system has not completed its work normally, then the next time it may refuse to boot at all. Then the next time it starts, it can display a menu with various options for the user's actions. By this, she, as it were, signals - "correct me!". And we will have to do something from what the inscriptions on the screen prescribe to us. For example, select a menu item - so we will try to enter Windows in the normal way. After making sure that this is impossible, we try to log into the system in safe mode - often this alone is enough for the next attempt to log into Windows to end successfully.

There are other options designed for advanced users. For example, after turning on in safe mode with command line support, we will need to enter console commands, and confident knowledge of such tools is quite rare among ordinary users. This menu can be accessed when the computer starts by holding down the "F8" button. As an example, consider the situation: you installed a new driver, as a result of which the system refuses to boot normally and a black screen appears. What to do? Select protected mode with a gray cursor (you can even without network driver support), log in to Windows, uninstall the driver and continue to work normally.

Viruses and hardware malfunction

If I was upset by the black screen on the monitor of a computer or laptop when turned on, I can do otherwise. For example, check the hardware on the motherboard. How to do it? After all, there are so many obscure details? In our situation, the video card is usually to blame. If the image does not appear, Windows does not start, and all other alternatives have been exhausted, then it is the problem. A couple of times I had this problem. This happened to me when testing old video cards on a regular old PC. The fact that the card does not work is understandable and so - there are no questions "why" here. As soon as there is no cursor when turned on, this means that something is wrong there, in the system unit (or laptop case). You need to do the following:

Open the case and inspect the video card connector. If there is not a tight connection, then you need to insert the card into the slot more tightly and send the system to reboot. It happened to me that this did not give the desired result either: the next launch in the usual order - and again before my eyes a black screen with missing menus and a cursor. I had to do a visual examination of the card: remove it from the slot and carefully examine the surface. Dirt and suspicious spots can be observed there - this is the first sign of a malfunction. Such dirt appears on any equipment that is not regularly cleaned.

I remember that I, too, could not be forced to “ventilate” the system unit with a vacuum cleaner. But, only if you do this regularly, the system starts up normally. Otherwise, such breakdowns will become your constant companion. You can try cleaning the card by soaking a cotton swab in regular alcohol. To prevent problems from occurring again, do not forget to scan your system for viruses. Some of them are able to bring Windows to the handle.

Today I would like to discuss with you the reasons why the computer turns on, but there are no images on the monitor. In other words, "a black screen hangs."

The black screen when you turn on the computer is not always the same. It can be divided into 3 parts:

  1. Black screen due to the fact that the power connectors for the monitor are not properly plugged into the outlet and into the monitor itself, or the monitor is not connected to the computer with a cable.
  2. Black screen immediately after pressing the power button. That is, the monitor turned on, but there are no initial splash screens of the motherboard, inscriptions and numbers before the operating system is loaded. This is a hardware level issue. Most often in this case, the sign "No signal" hangs. It is also possible that the computer starts beeping. The signals may be different. Below, we will analyze in more detail how to restore the computer.
  3. The computer turns on as usual, there is an initial splash screen of the motherboard (not all computers should have it, so don't be scared), inscriptions, numbers run, and after all this goodness, the normal system boot begins. After that, a black screen just hangs, and sometimes a black screen with a cursor. The appearance of this problem is most likely a software level and it is quite easy to fix, except when the hard drive has come to an end and the computer simply cannot read information from it.

Causes of the black screen.

Below I will write absolutely all the reasons due to which a black screen pops up when you turn on the computer, and then we will consider each of them in detail.

  1. Your computer needs to be cleaned of dust.
  2. Faulty video cable (VGA, HDMI, DVI) or monitor.
  3. Bad video card.
  4. A problematic program or driver.
  5. Hard drive problem.
  6. Other hardware failures.

Now, let's look at each of these reasons in turn. Go!

  1. Your computer needs to be cleaned of dust.

The computer turns on, but instead of the usual boot, a black screen hangs? This is a fairly common problem. In 80% of cases, this is due to the fact that a large amount of dust has accumulated inside the system unit. In this situation, you need to pull out all the computer components from their connectors, remove the cooler and processor heatsink, and then thoroughly blow them and the system unit itself from dust using a special can of compressed air. (sold in any self-respecting computer store) You can find out how to do this in the article "" Also, I would advise you on the processor, video card and other chips, (where it is required) and also (if necessary).

  1. Faulty video cable (VGA, DVI, HDMI) or monitor.

Perhaps the reason that the computer turns on, and a black screen hangs on the monitor, is a faulty video cable.

It is of three types:

In order to test this theory, you need to connect the system unit using this cable not to a monitor, but to a TV. Or just borrow a known working cable from a friend.

In the same way, by the way, they check the computer monitor.

  1. Bad video card.

This cause also causes a black screen when the computer is turned on.

The fastest and most effective way to test a video card for performance is to substitute another video card in its place. If an image appears when you turn on the computer, go to the store for a new video card.

  1. A problematic program or driver.

This reason, due to which the computer turns on and then a black screen appears, is fundamentally different from all of the above and below described. The fact is that the problem is most likely at the software level. Remember what you did the last time the computer was working? Perhaps you downloaded something, installed something, or deleted something. A black screen with a cursor most often occurs when the video card driver is corrupted. In order to correct this misunderstanding, you should go into safe mode. To do this, restart the computer and as soon as it starts to turn on again, press the F8 key. The launch menu will open in front of you. It may look different. (it depends on what system is on your computer)

This is how the menu looks on Windows 7.

After the computer has booted into safe mode, you need to do a system restore. An article on how to do it right lies

If the computer does not boot into safe mode, then 2 options are possible:

  • System damage is too global (in this case, you should and But before you do this, you should check the hard drive for errors and fix them. (If possible) It is also possible that after correcting errors, the system will start as usual.)
  • Hard drive problem (read the article below)
  1. Hard drive problem.

A black screen on a computer monitor may also indicate that something is wrong with the hard drive. To check and try to troubleshoot, the Victoria4.46b program is used. The video below describes in great detail and shows how the program works. I will only add that in order to restore damaged sectors (errors), you will need to put the switch in the Remap position before starting the test.

By the way, the video shows how to check the hard drive during a working operating system. But Windows does not work for us. In order to check the HDD without loading the system, we need to write the Victoria 4.46b program to disk in a special way (the Internet is full of instructions on how to do this) and it will not boot from the hard disk, as we usually do, but from the disk Where is Victoria. How to boot from disk read

  1. Other hardware failures.

If you, in turn, tried all the methods that are described in this article and nothing helped you, then most likely there was a serious hardware failure. You should take your computer to a service center for diagnostics. Specialists will check everything and tell you which part should be replaced.

This is where my article comes to its logical conclusion. I hope it helped you to remove the black screen from your computer monitor. Thank you for attention! Good luck!

The appearance of a black screen when loading the operating system can at least cause confusion for the user. What is the cause of the malfunction when a black screen appears when you turn on the computer? In this case, there seems to be a launch, but the image itself does not appear (nothing is shown on the monitor). In some cases, even the cursor is missing, there is no signal, and measures must be taken to quickly correct the situation.

Then how to remove the black screen on a working computer when no image appears on it when turned on? First of all, you need to understand what exactly is the cause of the malfunction. The reasons for such a breakdown include technical and software, but in 50% of cases the user himself is to blame due to his inattention, and sometimes simple ignorance.

An example from life. Bought a motherboard with an integrated graphics card. An optional external graphics card has been purchased to increase gaming performance. When building the PC, everything was connected correctly and worked perfectly. Further, after cleaning or transferring the system unit, the wires were disconnected and reconnected incorrectly. The wire from the monitor, instead of an external video card, turned out to be connected to the built-in one (VGA or DVI connectors are the same on all devices). Naturally, the PC was configured to work with an external video card and it simply would not start with the built-in one. Inattention or ignorance? Draw your own conclusions.

The technical reasons why the monitor does not turn on, the cursor is not visible and there are no standard boot labels are as follows:

  • The PC is switched to the mode for working with an external monitor (in this case, the absence of a signal is relevant for laptops).
  • Loop malfunction (also a problem that is relevant only for laptops).
  • Video card failure.
  • The cable was connected to the wrong connector.
  • The cable that connects the system unit and the monitor comes off - again, a black screen appears after loading.
  • The power is off at the monitor, so it does not start, nothing appears on the screen, not even the cursor.
  • Monitor malfunction.

Software malfunctions that lead to the fact that a black screen does not turn on when the monitor computer starts up include:

  • The presence of a virus malware that prevents the computer from performing work. It is because of it that a black screen is shown on the monitor.
  • Inappropriate screen resolution.
  • Your computer's graphics card has an incorrect refresh rate.
  • Incorrect operation of the OS loader or drivers.

Solving technical problems

To solve technical problems, how to remove a black screen, it would be wise to use the following action plan:

  1. You need to make sure that the personal computer is turned on. To do this, the presence of working light signals, the sound of a working cooler is checked. The cursor does not appear.
  2. It is checked whether the cables connecting to the system unit, the power cables to the monitor are connected, and whether the button on the monitor is turned on.
  3. If a black screen occurs when the computer is turned on, then a check is made of the place where the cable is connected to the socket. If necessary, you can reconnect the cable.
  4. If the computer uses an integrated and external video card, then you need to check which of these devices is connected to the monitor. You may need to switch the cord to a different jack.

Laptops almost always provide an output to connect an external monitor. If, when starting the laptop, the sound of coolers is heard, which is accompanied by a black screen on the computer, then it is likely that the mode of working with external monitors has been launched on purpose or by accident. On the keyboard, you should find the function keys for controlling the operation of an external monitor and try to turn on the internal display.

The F7 key turns on/off the internal screen, and the F8 key controls the combination of output to the internal/external monitor of the laptop. They must be pressed at the same time as the function key, which is usually labeled Fn.

Different modes of operation are switched by sequentially pressing the following key combination: Fn and F8. Considering the question of how to remove the black screen, you can try this method if the laptop's internal monitor was accidentally turned off.

If you are sure that the black screen with the cursor is caused precisely by technical problems, and the above steps did not help you resolve the issue, there is still no signal, then you should contact the repair company or service center. In this case, you are unlikely to be able to fix the problem yourself.

Solving Software Crash Issues

If you encounter a black screen after turning on your computer due to malware or a software glitch, then it is recommended that you follow these steps:

  1. Try booting the operating system in safe mode. If you succeeded, then you need to continue to follow the steps below. If not, then the only option would be to boot the operating system using external media.
  2. When the operating system is loaded in safe mode, it is worth checking the refresh rate and screen resolution settings. If the computer monitor has not been turned on before, then they need to be replaced with the correct ones.
  3. Then the video card drivers are updated. Although safe mode is also used, this should be done using the device manager.
  4. If the monitor on the computer turned on for a long time, then you need to start the anti-virus program and carefully scan the PC for the possibility of infection with malicious software. Ruthlessly destroy all files that pose a threat.
  5. After completing all the steps, the computer should be restarted.

When the monitor turns on, immediately turns off, or a black screen occurs after switching to a new monitor, you need to do the following:

  1. The old monitor is connected to the computer.
  2. The screen resolution is set to the minimum and the refresh rate is set to 60 Hz. This is done in a special graphics card driver utility or in the display properties.
  3. The computer is connected to a new monitor. Now you need to adjust the screen resolution and frequency for the new display.

There are times when, with the complete technical health of the computer, the above steps do not help solve the question of what to do if the computer has a black screen. In this case, you can contact the experts. Some malware is only detected manually, while antivirus programs will be useless.

Unusual Reasons

What to do if the black screen is not caused by technical or software means? A black screen may appear due to the banal inattention of users, which sometimes reach the point of absurdity. Before starting the search for complex causes of the problem, it is worth checking your attentiveness:

  • Could you deliberately or accidentally reduce the brightness of the monitor to a minimum? Then you can’t say that the monitor turned on for 2 seconds and goes out, but the image itself is missing.
  • Do the metal parts of the PC “short”? Static electricity can get on computer cases. The device will start shutting down suddenly for the user, even when booting up. This problem is often caused by touching the body of elements that conduct current, or a large accumulation of dust inside the system unit.
  • It is worth listening to the sound of the cooler. Does the fan work, are there any unusual sounds? Often, due to a malfunction of the cooling system, a sudden shutdown of the PC occurs. To avoid such a problem, the computer must be kept clean. It should not be leaned with a cooler against cabinets, walls and should not be placed near batteries.

The problem of a black screen appearing when turning on the computer is solved by fixing a specific error. If you check the case for the passage of static voltage, turn up the brightness or replace the cooler, the problem can be solved.

In any case, the appearance of a black screen should not lead the user to panic. In a fit of fear or bewilderment, you can only aggravate the situation. You can’t knock on the system unit and monitor, this will not solve the problem, but it can even completely disable the computer. It is still not recommended to disassemble the system unit yourself and switch the wires in it if you do not have experience in fixing it, and you do not know how the computer works.


A fairly common situation - when you turn on the computer Windows won't boot and appears black screen(not to be confused with).

unequivocal answer, why is there a black screen in windows it’s impossible to give, since there can be many reasons - from a banal power outage (for example, they turned off the light), and you, without knowing it, press the computer’s power button in a rage, to more serious ones - failure (breakdown, malfunction) of the hardware and problem with PC hardware (power supply, processor, motherboard, monitor, etc.).

If nothing happens at all when you turn on the computer - you don’t hear the noise of the cooler (fan) rotating, the indicator lights don’t light up, then first determine whether power is being supplied to the computer. Check the socket (any household appliance), 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 completed the above steps, but a black screen appears when you turn on the computer, you can safely talk about a PC hardware malfunction. If your computer or laptop is still under warranty or you do not understand hardware, then it is better to take it to a service center to specialists. Those who are not afraid of experiments can try to eliminate the cause of the black screen on their own, if you're lucky - save money on repairs.

To begin with, completely turn off the power to the computer, disconnect all cables and wires, remove the side and front panels (depending on which case). Start small - take a look at the Power start button, maybe it's just broken.

Inspect the computer hardware and wires for signs of mechanical damage and short circuits - soot, soot, if necessary (if the PC is dusty), clean the computer from dust. You can read how to clean your computer yourself at home.

Do not forget to check all the 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 causes of a black screen on a PC are the 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 deadline has come - they 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. Checking is easy and simple - the monitor can be connected to another computer, laptop, or simply to an outlet (if it is working, NO SIGNAL will appear). I just connected the TV to the 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 a computer freeze can also appear if the BIOS is configured incorrectly. You can read about settings and restoring Bios by default on our website.

There are times when the computer freezes with inscriptions on the display with a black screen. Perhaps the mode will help Loading Last Known Good Configuration with Working Options" or "" and Windows System Restore if not disabled with the .

The program can fix some causes of the black screen. You can also reinstall the operating system if the black screen was caused by software.
