The tablet restarted unexpectedly or encountered an unexpected error. The computer restarted unexpectedly or encountered an unexpected error. The impact of viruses and the method of their neutralization if the system cannot be loaded

If you have the problem "The computer restarted unexpectedly ... (The computer restarted unexpectedly ...)", then you can solve it by reading this article.

I had the problem of an unexpected reboot and I couldn’t solve it for about a week and didn’t understand what was the matter, because I saw this for the first time. And I tried different methods. The described method helped me, but temporarily, after 2-3 reboots of Windows or installing any driver, Windows no longer loaded giving an error.

I tried different versions of Windows, formatted my SSD via LiveCD, via Paragon. I did both quick and full format, which takes much longer than the quick one that can be done when installing Windows. I burned different bootable flash drives, tried a bunch of options, but nothing helped - after a couple of reboots, Windows no longer loaded.

To solve the problem of an unexpected reboot, then at the time this error occurs, press Shift + F10(hold down the Shift key and press F10) to open the Windows console. Further type regedit and hit enter to open registry editor.

Next, you need to go to HKEY_LOCAL_MACHINE > SYSTEM > Setup > Status > ChildCompletion. To open the folder structure, double-click first on the HKEY_LOCAL_MACHINE folder, then double-click on SYSTEM, then double-click on Setup.

There will be a setup.exe parameter and a value of 1 in hexadecimal.

Instead of 1, put the number 3 and click OK.

After a couple of minutes or ten minutes, Windows will be installed and you can continue or start working.

Why does the error “The computer restarted unexpectedly, or an unexpected error occurred. Unable to proceed with Windows installation. To install Windows, click the OK button to restart your computer, and then restart the installation."

Finally I figured out the problem. , and later . After installing the SSD drive, there were no big problems, although they always climb out on my laptop, but I solve them. But after changing the RAM, an unsolvable problem appeared for about a week and no online advice helped.

I decided to act: I took out my old 2 sticks of RAM and installed a new one. The computer worked the memory test passed normally, tested the memory for about 2 hours and no errors. But removing the new RAM and putting the old problem solved. I was even able to enable AHCI mode for the SSD drive and install all versions of Windows.

Therefore, if you have a problem installing Windows and the error “the computer restarted unexpectedly ...” is displayed, remember what you recently changed on your computer and remove it by returning the old one.

I will order more RAM anyway, but now I will only take Samsung, as well as my Samsung SSD and Samsung laptop. Before that, I checked the RAM and it should have been suitable for a voltage of 1.5 Volts and for megahertz and supported by my motherboard in terms of volume. But in the end, after a long search for a solution, the problem turned out to be exactly in it. It is not compatible with my laptop for some unknown reason.

But as I recently looked again on the intel website and in the aida 64 program it turns out that my laptop supports a maximum of 1066 MHz, but for some reason it seemed to me earlier that it supports 1600 MHz. This is where I think my mistake was. There was an incompatibility in Megahertz memory.

Here is a video on this topic.

One of the most disturbing and unpleasant signals for any user is the appearance on the screen of a system message that the computer has unexpectedly rebooted or an unexpected error has occurred. Naturally, a spontaneous restart can scare anyone. The saddest thing is that such an error can appear in completely different situations and indicate both conflicts in the software environment and possible problems with hardware. Next, we will consider the most typical situations in which this failure occurs, as well as the simplest methods for eliminating problems that arise.

The computer restarted unexpectedly or encountered an unexpected error: possible reasons for the failure

As for the occurrence of problem situations, there can be quite a lot of them. For some reason, it is believed that in most cases, the appearance of a notification that the computer has unexpectedly rebooted or an unexpected error has occurred is associated exclusively with computer hardware. This is not always the case, although it could be the root cause. Even when installing drivers or other software, the possibility of such a failure is not excluded.

But among the main situations, a few of the most common ones can be distinguished:

• exposure to viruses in a running system;
• clean installation or reinstallation of the OS;
• inconsistency of drivers or installed programs with “iron” equipment;
• problems related to the performance of hard drives and RAM sticks.

The impact of viruses and the method of their neutralization if the system cannot be loaded

It goes without saying that a viral impact on the OS cannot be ruled out. Many modern threats are able to disable any system. For example, you can even meet those that focus the maximum light power at one point on the monitor, which is why it simply burns out. But this is so, for example.

If the failure is really related to viruses, and restarting the computer in normal mode or with a safe start fails (the error appears again), the user has no choice but to check the system for possible threats exclusively using boot utilities like Kaspersky Rescue Disk. Such programs are written to removable media (optical disks, USB devices), have their own boot records to start even before Windows loads, and can find deeply hidden threats not only on hard drives, but also in RAM. After starting from such a disk, in order to identify all possible threats, it is better to set not the standard scan offered in the default settings, but select all logical partitions and boot records using deep scan.

Installing or reinstalling the system

Perhaps the most common is the situation when a failure manifests itself at the stage of installing the system. This also displays a message stating that the computer restarted unexpectedly or that an unexpected error occurred. How to fix such a problem, few know. The situation is aggravated by another unpleasant factor. The fact is that you can restart the computer, but in most cases the error occurs again, and on subsequent restarts it loops.

What is the saddest thing, no means help, except for one. When a failure message appears on the screen, the first step is to call the command console using the Shift + F10 combination for this, and write the registry editor (regedit) call string in it.

In the registry in the HKLM branch, through the system catalog, the installation and status folders, get to the ChildCompletion section, in which the setup.exe key will be shown on the right. Either through RMB, or through a double click, you should enter the editing of the parameter and change its value from one to three, confirm the actions by pressing the OK button and restart the Windows installation after restarting the computer or laptop. Usually after that the problem disappears.

Possible Windows errors at the stage of installing drivers or user programs. What to do?

Unfortunately, a failure with a notification that the computer restarted unexpectedly or an unexpected error occurred can also manifest itself in a working system, when the user independently installed drivers for some devices that do not suit them, or software that is incompatible with neither the system nor with " iron." The problem, though unpleasant, but solvable.

If a normal restart does not fix the error, you can try to restart the computer and roll back by selecting from the start menu called by pressing the F8 key to load the last known good configuration or try to start in safe mode, then remove the failed drivers or programs that were installed recently and caused the appearance of failures in the operation of the OS.

RAM Conflict Issues

An equally common problem can be called failures in the operation of RAM strips. In particular, this applies to replacing them or increasing existing RAM by installing additional brackets.

In this case, you will have to remove each bar in turn and reboot the system. If a problem bar is identified (when the system boots up normally), it will need to be replaced. Particular attention should be paid to the technical characteristics of the memory and motherboard. This applies to the supported volume, voltage and operating frequency. In other words, in a motherboard slot designed for 2 GB, 4 GB of "RAM" will not work. The same goes for installing 1600 MHz memory in a 1066 MHz only slot. And of course, the operating voltage should be taken into account.

Problems with SSD drives

Finally, the most unpleasant situation concerns SSD hard drives. For some reason, it is on them that such a failure appears most often. Of course, at the system installation stage, you can try to delete all logical partitions or completely format the hard drive, but, as practice shows, in most cases such actions do not give the desired effect.

One solution may be to switch the operating mode during system installation to IDE (this is a prerequisite), and use AHCI in a running system. These settings can be changed directly in the BIOS/UEFI Primary I/O.

Summary

If we draw a line under all of the above, we can note the fact that in most cases the error appears at the stage of installing the system. Other situations are not so common. If we talk specifically about RAM and hard drives, it is better to select equipment of the same brand, for example, install on Samsung laptops and a hard drive, and memory only from this manufacturer. In this case, the appearance of conflicts is excluded almost one hundred percent.

Sometimes during a clean Windows installation or upgrade to Windows 10, the user encounters a problem like:

The computer restarted unexpectedly, or an unexpected error occurred. Unable to proceed with Windows installation. To install Windows, click OK to restart your computer, and then restart the installation.

The administrator agrees (nowhere to go anyway), presses OK and ... the computer restarts again with the same error. And so time after time. Unfortunately, at this stage there is very little information about what is happening, and, meanwhile, there are a lot of reasons: from and to hanging in some installed program. At the same time, as practice shows, the installation problem lies in wait for users of any version of Windows: from 7 to 10. The last time I personally encountered such an error after processing the next version of Windows through, which means that I needed an extended solution to the problem. Which I will present here.

Computer restarted unexpectedly...

So what can be done? If the system is capable of showing dialog boxes, then everything is not so bad, and we will most likely have access to repair utilities from the System32 folder. Try the following solution to the problem: it is not new, it is googled in any language and has been known since time immemorial:

• during the next attempt to install Windows, we are waiting for the appearance of a window with an error
  after it appears, hold down the keys Shift +F10 and go out to

• in it by the team

regedit.exe

call the registry editor

• from there we go to the section

HKEY_LOCAL_MACHINE\SYSTEM\Setup\Status\ChildCompletion

• on the right you need to find the parameter setup.exe. Most likely, its value is set to 1 . If so, change to 3 double click on it:

We just forced the installation process to jump to another level, skipping the "incomprehensible" error so far

• you can go into reboot right now from the console window with the command

wpeutil reboot

Try installing/updating Windows again. I'm sure that the upgrade or installation process will now run smoothly. If the error repeats or you encounter another one (up to the process freezing) - dig towards the iron components of the computer.

However, in the meantime, I need to get Windows out of this mode and prevent the error from appearing again. Let me remind you that the problem appeared in the Audit mode sysprep. So, we continue to dig the registry. I don’t go to reboot and in the registry I go to the section:

HKEY_LOCAL_MACHINE\SYSTEM\Setup\Status

where the following parameters in the following subsections are assigned the following values ​​in total:

~\AuditBoot- 0

~\ChildCompletion\setup.exe 3

~\ChildCompletion\audit.exe 0

~\SysprepStatus\CleanupState - 2

~\SysprepStatus\GeneralizationState - 7

~\UnattendPasses\auditSystem - 0

Windows exited after reboot audit, loaded in mode OBE. I had to recreate it so that Windows would safely hide it again at the next installation.

Good luck to everyone.

The essence of the problem: When installing Windows 7 at the last stage (after an error, after a blue screen, or after an emergency shutdown), the computer restarts cyclically and the message is displayed:

The computer restarted unexpectedly or encountered an unexpected error. Unable to proceed with Windows installation. To install Windows, click OK to restart your computer, and then restart the installation.

in English:

The computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed. To install Windows click OK to restart the computer and then restart the installation.

Solution to the problem:

When this error occurs, press the Shift + F10 keys on the keyboard, the command line will start, enter the regedit command, thus launching the registry editor. We are looking for the HKLM\System\Setup\Status\ChildCompletion section. In the section there is a key called setup.exe. If the key is set to 1, then double-click to change it to 3. Then close the registry editor and restart the computer

When working with a PC, users often notice that the computer restarted unexpectedly or encountered an unexpected error . Such a mistake can panic anyone: unsaved data, loss of important information, loss of time and money for unplanned repairs. Most often, such a window appears when reinstalling the operating system, giving us anxiety. But, do not rush to panic, below we will talk about what needs to be done in such situations.

Finding out the reason

First you need to determine what is causing this error. Answering this question will make your task at least half easier. Here are the most common causes and situations in which an error appears on the PC screen or it restarts on its own:

Reinstalling the operating system

Most often, a sudden reboot and an error pop-up occur during a system reinstall. There are quite a few reasons for this behavior of the PC. However, to solve them, you will need skills in working with the registry. If you do not have such skills, it's too early to get upset. Perhaps it's something completely different. If you are not afraid to enter the registry, when you reboot or the error displayed on the screen, click Shift+F10. On the command line that appears on the screen, write regedit. Find the parameter setup.exe by the address HKLM-System-…, change the key value to

Recreating the hard drive

If the registry entry method did not solve the problem, use the following method: Delete and re-create the partition on the hard drive where the operating system was located. This will require special programs and utilities, or directly installer Windows(disk or flash drive with OS).

The easiest way to solve the problem of reboots and errors is to use the installer. Press " Disk setup” in the installation window, during the installation process. In the window that appears, you can start recreating it. Pressing the button " Delete section” will lead, respectively, to deleting the partition. Button " Create section' will add a new cell. The main thing is to select the necessary parameters, enter the required volume. Next, save the changes and continue with the installation. The issues under consideration should disappear.

Hard drive replacement

However, there are situations in which problems with a hard drive cannot be so easily solved. An unpleasant signal may be a pop-up unexpected mistakeSSD or sudden restarts of the computer. This is a particularly bad signal for users who have already tried the above troubleshooting methods.

All this can also happen due to a breakdown of the hard drive installed in your computer. Moreover, even repairing the disk, most likely, will not work. The problem will be solved by a complete replacement of the faulty unit with a new one. This method is not the easiest, but effective. After replacing, change back to 3 parameter setup.exe, as described above. This method will help you avoid unnecessary problems associated with reinstalling the OS.

Problem Applications

In the process of working with the installed Windows operating system? There may be several options for solving the problem. Still, you should not rely on them 100% if you do not have at least basic knowledge of computer diagnostics. We have already talked about the errors associated with the installation of utilities, dubious games and programs. We advise you to remove all installed programs that could be causing errors and reboots. This can be done using standard OS tools by opening in " Control panels" chapter " The installing and deleting of programms».

In most cases, this will solve the problem. You can also use the standard features Windows to reset the system. A few minutes and your problem will be solved. However, it is better to say goodbye to dubious applications.

Attack of evil viruses

The computer restarted unexpectedly or encountered an unexpected error is a problem that requires a timely response. Perhaps this is a consequence of the attack of malicious viruses. First, try to deal with the problem by scanning your computer with an antivirus.

On our website you can find an article about .

If it doesn't help, roll back the system. It is advisable not to delay with this in order to avoid infection of all sections of the system. The registry needs to be cleaned. As a last resort - reinstall operating system. When in doubt, use the services of specialists. They will return your computer to life, its previous performance, troubleshoot, quickly and without unnecessary loss of your nerves and information.

Actually, that's all, now you know what to do if the computer restarted unexpectedly or encountered an unexpected error. Enjoy and more importantly, stable use of your PC!
