A black screen appears when the computer starts up. Black screen appears when loading windows

WHEN LOADING WINDOWS A BLACK SCREEN APPEAR.

Black screen when booting Windows 7- the situation, to put it mildly, is not pleasant. Let's try to figure out how we can remove this black screen at boot. On the Internet, you can find information on any problem that has arisen or ask a question on a topic of interest to you, although such information does not always help. We will tell you how the problem of a black screen when loading Windows 7 can be solved on your own, without resorting to the help of various service centers or private computer specialists. At the same time, you will also save a lot of money.

Windows has stopped loading?

First, consider the option if the operating system does not boot at all. This may be due to a malfunction. hard disk, and this, as a rule, leads to an error when loading system files, or there may be an error when loading some service or some kind of driver.

Earlier, if you heard this expression, there was a "Blue Screen of Death", which was very much feared by users using Windows previous versions, now it is gone, and instead a black screen appears, although it shouldn't scare you right away, because you can work with such a screen.

The first thing you should try is safe mode boot Windows. How to do it? When you start the computer, after diagnosing the BIOS, which occurs without your participation from the very beginning of the computer's operation, you need to press the F8 key and hold it for a few seconds. In the on-screen menu that appears, select "Safe Mode". See the screenshot below.

What does Windows Safe Mode mean?

Safe windows mode(safemode)- this is a special mode, by choosing which you will start only the basic services and at the same time only the basic functions work. For reference: this mode is available in all Windows operating systems (from Windows XP to Windows 7).

Very often there are cases when this startup mode is necessary, this is when the system is infected with viruses. Also, you need to enter the system in this mode if you need to copy information from the hard disk when on Windows computer does not start.

When you enter "safe mode", you will be able to cure your computer, while restoring files that were damaged in operating system, thus returning Windows to work.

Starting Windows in this mode, both in Windows XP and in Windows 7 or other operating systems, is the same. Let's see the sequence of actions.

1. With the computer turned off, you need to turn it on by pressing the power button. When Windows is running, we reboot.

2. First, when the computer starts up, the logo of the main system appears, that is, the BIOS input / output, as well as data on the computer test results: processor, memory, hard drives etc. You must not miss the moment when testing is almost complete, and Windows has not yet started to start, you need to press F8, which is located on the keyboard in the top row. (F8 is more convenient to press quickly several times). This, instead of loading Windows automatically, that is, in normal mode, leads to the appearance of the startup selection menu.

3. You will be offered a choice of Windows boot modes: several safe (safemode) or "Normal Windows boot" to choose from:

• Safe mode- this is standard version, it starts Windows with a minimum of features. You need to use it in cases where the computer does not have an Internet connection or local network and also if necessary, blocking access to the network during Windows startup.


• Safe Mode with Boot network drivers - if you select this mode, an additional function of working with the network will be added.


• Safe Mode with Support command line - here it is additionally possible to enter commands for working with operating system files from the keyboard. This mode is intended for professionals, that is, system administrators.

4. Choosing one or the other safe mode will load the operating room. Windows system according to the selected parameters. You will visually see the difference compared to normal startup by seeing the indications of which system drivers are currently being loaded. When Windows is finished loading, there will be an inscription that the system is booted in safe mode. You may need to confirm the entry into this mode, it all depends on the operating system.

If Windows has booted in safe mode, therefore, the cause of the malfunction must be looked for in some service or driver.

Sometimes, it is impossible to boot Windows even in "Safe Mode". If you know what is the name of the driver or file that is preventing Windows from loading, just disable it.

To do this, you need to insert the installation Windows disk into the drive and boot from the operating system CD. When the first installation window appears on the screen, you need to press the key to go to the menu for Windows recovery.

Next, you will be prompted to select a copy of the operating system, this is when not one, but several operating systems are installed on the computer, you need to select which one you want to restore, and then press the key.

Today, most people use the Internet, the primary source of why it appears when downloading Windows black the screen is the Internet itself, or rather the viruses that we pick up on not very high-quality pornography sites, or when downloading a program from a site with a bad reputation, and the like. Some people think that a black screen may appear after updating the operating system, this is possible only when your Windows 7 is not original, but a broken line, and is activated with cracks, patches, keygens. You need to download the original high-quality image and activate it legally, or buy a licensed Windows 7 distribution kit.

Based on the above, we have identified two variants of this problem: illegal activation with subsequent updates and the second is viruses and trojans.

І. Let's figure it out with the first option, why the black screen when booting windows 7 linked to activation and subsequent updates.

If on a black screen in the bottom corner the following message is displayed: “You may have purchased a fake copy of software... This copy of Windows was not authenticated " , it turns out that you are using a non-licensed OS. In those who use Windows version with a license and, accordingly, has an activation key, you just need to reactivate Windows, you can also contact the service technical support Microsoft, if your Windows is broken, then the whole problem is from Windows updates KB971033, it is this that verifies your OS for authenticity.

ІІ. Black screen when booting Windows 7, if your the computer is infected with viruses or trojans... What to do?

Option number 1:

1. We call the Task Manager, for this we press simultaneously the “Ctrl + Shift + Esc” keys, while you will see the “Task Manager” window, then press “Application” -> “New task”, in the window that opens we write “regedit”, below in the screenshot.

2. After the "Registry Editor" window appears, you need to find the following branch in the registry:

HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / WindowsNT / CurrentVersion / Winlogon

By double clicking on the item “ Shell“, In the window that will open there should be only a record explorer.exe, if there are also other entries, then they need to be deleted, leaving only "explorer.exe", in the case when there are no other entries besides the entry "explorer.exe", then you need to delete it, and then create again new entry where to write the value "explorer.exe", it does not always help, of course, but you need to try all the same.

Option number 2:

And what should be done when the first option does not help? The task manager does not open, since it was blocked by the administrator, and the system restore does not help either, even if you reboot the system again, neither safe mode, nor editing the registry, what then?

And the last remains reinstalling windows... And there is another solution, and it is quite simple - sticking shift, we think everyone knows about it.

1. You need to press the key five times quickly shift, or you can just press and hold it pressed for about 10 seconds, then a window will appear with the inscription "Turn on Sticky Keys?"

2. Go to accessibility center where we turn off keyboard shortcut.

3. In the upper corner we write, "Task Manager", or you can write just "dis".

4. When you open the "Control Panel" window, you need to go to the "System" item, or you can do this through ("Administration", then the "System Configuration" item, where we go to the "Service" and of course "System Restore Confirmation of the restore point

After all the manipulations done, we advise you to download the free MalwareBytes Anti-malware utility to check your system, it will help you find all viruses and Trojans on your computer, from which this very black screen appears. Ask why this program, but because anti-virus programs simply do not see, and therefore ignore all these viruses and trojans. To avoid problems associated with the appearance of a black screen when starting Windows, it is also recommended to use programs to optimize your computer. And one more note, we recommend to parents, to restrict the access of your children to poor quality web resources, and thereby you will reduce the risk of infecting your "PC" with viruses and Trojans.

You bought a computer, or was it given to you, or you now have it in use at your new job. You are happy as a child, this is the most interesting toy, and listen to music and make a video connection with someone on Skype, play games, surf the Internet, watch a movie. It allows you a lot, but ... It so happens that suddenly, and this always happens suddenly, the computer does not turn on. Yesterday everything was fine, and today a misfortune happened.

This article will help you categorize the problem, isolate it, and not make it worse.

Let's divide everything by points:

1 - The computer does not turn on- that is, in general, it does not respond to pressing a button, the fans do not spin.

2 - The computer turns on, but besides the buzzing of fans and blinking of bulbs on the system unit nothing else happens, the monitor screen is dark.

3 - The computer turns on, but something is written on the screen in white letters on a black background.

4 - Blue screen- The computer turns on, the operating system starts to load, but then the screen turns blue and something is written on it in white letters

5 - The computer turns on, the operating system boots, but a banner appears on the screen blocking work.

1 - The computer does not turn on

For starters, don't panic.
Open the side cover system unit, and carry out preventive cleaning.
See how much dust there is? And dust is our first enemy. Take a regular brush and knock off all the dust, then vacuum it up.

Dust is dangerous because when humidity changes, it becomes conductive, which leads to a short circuit of electronic components.

Dust - clogs the cooling system of the processor, video card, and power supply unit, hence overheating and failure of these elements.
Have you cleaned it up? Let's continue.

Let's deal with the power supply.
To do this, disconnect all power wires from the devices.

CD drive, hard disk drives, video adapter, FDD if you have one.

Power wires are those wires that provide power to devices. They usually have 4 wires, two black and one red and yellow. +5 and +12 volts are supplied to them.
Disconnected? Now we are trying to turn on the computer.
Happened?

We connect the wires back, but! One by one, starting with the video card. Thus, we can find out which device prevents the computer from turning on.

Did not work out? Computer won't turn on? We are trying to replace the power supply.
Disconnecting the two connectors on motherboard long and four-pin.

Did it work? Okay, plug everything back in, close the lid and keep working.

The computer still won't turn on? Your way to service center. It is better not to fix it further without knowledge and preparation.

2 - The computer turns on, but apart from the buzzing of fans and blinking of lights on the system unit, nothing else happens, the monitor screen is dark

Oddly enough, but first you need to repeat what is described in the first paragraph, when the Computer does not turn on.

If it did not work out, and everything is the same on the new power supply unit, you need to pull out all the boards from the system unit, except for the motherboard.

It happens that either the modem or the network card, or the TV tuner card fails, block the operation, and the computer does not turn on.

3 - The computer turns on, but something is written on the screen in white letters on a black background

This usually means that the computer cannot find the boot record.
That is, the media on which the operating system is installed.

Why does this happen?
Well, firstly due to a malfunction of the hard disk drive (hard drive). Either bad sectors appeared on it, or it does not work at all.

How to check?
When turned on, go to BIOS (basic water output system) and see if it is determined there HDD, and in the boot options it is worth loading from this disc.

It often happens that due to a voltage drop, the BIOS is reset to zero and all values ​​are set by default.
And by default, it happens that the SATA controller is in the only mode, which means that the system will boot only from it. And if you have an IDE standard drive, then it will become inactive.
Set the controller state to compatible mode, and after saving the settings, restart the computer.
This will help.

If the hard drive is not recognized in BIOS, then you need to go to the service..

It happens that there is such an inscription on the screen

This means that the hard drive is ok, but the system files are damaged ...
Here is the option to try to run the installation in file recovery mode.

Select R

In this case, your data will be saved, and the information will not go anywhere.

4 - The computer turns on, the operating system starts to load, but then the screen turns blue and something is written on it in white letters

This is the so-called blue screen of death.

Moreover, if at reinstalling Windows this screen appears again - this, as a rule, indicates a malfunction random access memory.
Try to pull out one ruler ... or rather, check the memory with a program, for example, memtest.

5 - The computer turns on, the operating system is loaded, but a banner appears on the screen, blocking the work

it virus... Trojan horse.
It will most likely look like this:

There are a lot of options:

It can take the form of porn banners of various modifications, but the meaning is always the same, you are required to pay money.
This should not be done under any circumstances, since still won't help.

Here you cannot do without specialists.
As a rule, this virus clears up quickly enough.

And finally, about one more malfunction of your computer.
Artifacts on the screen, multi-colored dots, dashes, stripes.

This symptom is very common today.
This is a malfunction of the Video card, unfortunately, the repair is quite difficult and often does not justify the costs.

Hello everyone! In this article, I invite you to find out the reasons for the black screen when starting Windows. Most of you, I think, have seen such a picture when, when you turn on your computer, instead of loading the desktop, a black screen appeared, or, as it is also called, "Malevich's painting", in which you were asked to choose the option of the subsequent loading of the operating system. If you do not understand what I am talking about, then I recommend that you familiarize yourself with today's article.

The appearance of a black screen when loading the operating system confuses many users, due to the fact that they have not previously encountered this type of malfunction when booting a computer. In turn, users begin to ask questions: why is it loaded? black screen on bootWindows 7 ? And for what reason the operating system does not load and, most importantly, what are the typical reasons associated with the appearance of a black screen when the computer boots?

One thing I can tell you is that the appearance of a black screen when the computer boots up is already a signal that your computer contains some errors that may affect the functioning of the entire operating system. Do you know what mistake many users make when they find a black screen on their computer at boot time? The mistake of users is that they immediately panic and start reinstalling the operating system, hoping to completely get rid of such a problem. Agree that knowing the problem of a black screen, you can solve it yourself more in a simple way thus saving your money. First, I would like to say a few words for what reason a black screen can appear at all.

In general, we can say that the reasons for the appearance of a black screen when the operating system tries to boot successfully can be a variety of situations. As an example, I will give you a situation when electricity was suddenly cut off in your house, and at that time you were working at a computer. Here is an incorrect shutdown of the computer, which in many cases is also accompanied by the appearance of various kinds of errors in the computer, which in turn is accompanied by the appearance of a black screen. There are also problems that arise directly in the hard disk itself (malfunction), hence the damage or deletion of system files, here is another example of the appearance of a black screen when Windows starts up.

Also, one cannot fail to mention another factor, which in turn contributes to the introduction of malicious code into the system, as a result of not only the appearance of a black screen, but also the freezing of the entire computer as a whole. I think you already guessed that we are talking about viruses. Therefore, ensure reliable protection of your computer by installing reliable antivirus program, and also check your computer more often for viruses and Trojans.

It remains for us to find out why there is no information on the operating system loading on the monitor screen, as it usually happens when the computer is turned on. Of course, if the situation is suddenly complicated by the need to perform complex repairs of computer equipment, then in this case you cannot do without the help of qualified specialists. I suggest that you consider the reasons that result in a black screen when the operating system tries to boot successfully. And before you contact qualified specialists, first of all try to diagnose yourself, because in most cases, as is usually the case, black screen on bootWindows 7 occurs through the fault of the users themselves.

Monitor state!

Yes, dear users, monitor, it is with it that you should start a full check. Is the monitor powered at all? In practice, I had one such case when a user could not turn on his computer for two days and was about to take it to a service center. More precisely, the system unit, as usual, turned on with the accompaniment of a sound signal, but the monitor at least blinked. In general, the problem was that the user, when reinstalling the computer to another room, did not fully install the power cable into the monitor. What was his facial expression when I told him what the problem was that his monitor was not working. Therefore, be sure to check the reliability of fastening of all wire pins, both in the monitor and in the system unit. Monitor connectors (VGA or DVI) must be securely screwed not only to the monitor, but also to the system unit.

In addition, you can check the performance of the monitor as follows, for this you will need to disconnect the cable that connects it to the system unit and turn on the power of the monitor itself. If, when the monitor is turned on, the indicator on it lights up, and an inscription appears on the screen, for example, "No Signal", then the probability of a monitor malfunction in this case will be low. Well, it is better, of course, to connect the monitor to another system unit (laptop) in order to fully make sure that it is working properly.

Black screen when booting Windows 7

So, let's move on, our monitor is working properly, and when the computer is turned on, we see the following picture. Instead of our usual desktop on which there should be program shortcuts, a black "screen of death" is loaded, in which you need to select the boot option.

In this case, the malfunction should be identified already in the system unit of the personal computer. As you can see from the figure below, for the further launch of the operating system, you will be offered one of the boot options. You also need to make sure that the computer successfully enters Safe Mode. To do this, you will need to periodically press the F8 key when turning on the computer. Then, in the "Additional boot options" menu that appears, go to the "Safe Mode" section and press the "Enter" key.

For those who do not know why there is a safe mode in the system, then in a nutshell, I will tell you that the existence of a safe mode in the operating system in many cases is an indispensable tool. After all, it is thanks to the safe mode that an operating system can be loaded that did not start, for example, due to a computer infection with viruses.

Safe mode can be launched in several ways.

Safe mode- basically this mode is started, which contains a minimal set of services and programs. Starts up this mode in the event that you do not need to use work with the network or the Internet.

Safe mode with loading network drivers- this mode just provides for starting the service to work with the network.

Safe mode with command line support- in this mode it is possible to use command input when working with the system. Typically, this mode is used by administrators.

Let's say that you have successfully entered Safe Mode, then the desktop has loaded successfully, in this case it is quite possible that the black screen during computer startup occurred as a result of a software failure (a certain service failed). For example, quite often users, installing some program or driver for the equipment, and the next time they turn on the computer, a black screen appears. In such a situation, I recommend that you delete recently installed program or a driver for recently installed equipment, due to which, apparently, a black screen took off.

In any case, if you have successfully entered Safe Mode, then do not be lazy to perform a full scan of your computer for viruses. To do this, you will need to use special utilities to check the computer for viruses, as well as to make sure that there are no malicious codes in the system registry. Most full information you can learn how to scan your computer for viruses and identify the most vulnerable spots in the operating system from the following articles:

Moreover, it should be noted that there are situations when viruses and Trojans were found and neutralized in the system, after which the black screen disappears and the computer boots successfully, but shortcuts and the Start panel are not displayed on the desktop. In this case, you can perform the following steps to additionally scan the system for malicious codes.

1. Press "Ctrl + Shift + Esc" and in the window that opens, go to the "Applications" tab. At the bottom of the window, click New Task. In the window that opens, enter "regedit".

HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / WindowsNT / CurrentVersion / Winlogon

In the parameter "Shell" there should be only the value "explorer.exe" and nothing else. If you find additional values ​​in this parameter, remove them and leave only the value "explorer.exe". The presence of any records in this parameter is extremely rare, but it is still necessary to check the cost.

Quite an interesting situation occurs when we cannot open the task manager yet, since it is locked and the computer does not enter safe mode. In this case, it will be possible to use one more simple method... Not all novice users know about "Sticky Shift Key". So here I am explaining, if you press five times Shift key, the Sticky Keys window appears.

1. The first thing you need to do is follow the link that is indicated in the Sticky Keys window.

2. Enter "Task Manager" in the search bar.

4. Now you just need to select the "System protection" item.

5. Finally, perform the recovery using the previously created control points, you can learn more about System Restore by reading the article "How to restore your computer in case of a failure."

For additional information I can suggest that you familiarize yourself with the following articles:

It often happens that video card drivers stop functioning properly and, as a result, the monitor is no longer able to display the set screen resolution. Here's more additional reason, which will definitely need to be checked.

Like everything else in our world, computer technology does not last forever. At some point at work personal computers crashes happen. Sometimes they lead to the complete incapacitation of equipment. One of the most common problems is a black screen when you turn on your computer. What is the cause of this problem and can the situation be corrected? Below we will try to figure it out.

Monitor problems

A black screen may appear when the computer starts up due to a malfunction of the monitor. This is evidenced by the absence of any inscriptions on the screen and sound signals from the PC speakers. Usually, excessive use of the monitor leads to this breakdown. In order to protect yourself from such a nuisance, it will be enough to carefully handle the display and install a surge protector.

Faulty cable

The next reason why the computer does not turn on and the screen remains black is the cable that powers the video card. It can be damaged if handled carelessly, for example, when wiping off dust. Also, if the cable is squeezed out of the connectors, it is often squeezed by furniture. To fix the problem, it is enough to firmly fasten the cable to the socket. If the cord is damaged, then you cannot do without buying a new part.

Tip: problems with the cable will never arise with careful cleaning and protection from pets.

Malfunction or incorrect connection of the video card

This problem is determined very simply - a black screen appears immediately when the monitor is turned on, and restarting does not help. It appears as a result of prolonged operation of the video card, as well as excessive heating of the system unit. For preventive maintenance, it is recommended to install an additional cooler that will work to cool this device. If a video card breaks down, it is better not to try to fix the problem yourself, but to trust a specialist.

Broken processor or RAM

When I turn on the computer, a black screen with inscriptions appears, or the PC emits intermittent beeps. The causes of failure can be very diverse - from the absence of a power filter to oxidation of contacts and mechanical damage. Precautions in this case will be the installation of a UPS and the above-mentioned surge protector. These devices will protect your PC from overheating and power surges.
