Windows does not load a black screen. What to do if, when you turn on the computer, there is a black screen with inscriptions? - 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

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 the blinking of lights on 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 of the system unit and carry out a 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-ROM 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 the 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 remove 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 because of 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 into BIOS (basic system of output water) 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 an 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 that the RAM is not working properly.
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 in any case, because still won't help.

You cannot do without specialists here.
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.

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 scientists. 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 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 Windows Safe Boot Mode. 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, 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 selecting 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 launch 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 the operating system, thus restoring 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 need not to miss the moment when testing is almost complete, and Windows has not started to start yet, 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 the standard option, it starts Windows with a minimum of capabilities. 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, the function of working with the network will be additionally added.


• Safe Mode with Support command line - here it is additionally possible to enter commands for working with files operating system 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 Windows recovery menu.

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 choose 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 directly 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 take a look at the first option, why the black screen when loading windows 7 is associated with activation and subsequent updates.

If on a black screen in the bottom corner the following message is displayed: “You may have purchased a counterfeit copy of the 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 it that checks 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 we press “Application” -> “New task”, in the window that opens we write “regedit”, below in the screenshot.

2. After the "Registry Editor" window has appeared, 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 only be 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
