Why doesn't the computer turn on when I turn it on? The computer won't turn on

The first step is to establish the cause of the malfunction. If the situation is such that the computer turns on, but then the operating system (OS) itself does not load, then naturally you need to dig towards the same OS.

And if the situation is that the computer does not even turn on at all, that is, it shows absolutely no signs of life, then the situation can be much worse.

A few recommendations on what to do if your computer won’t boot! Here, as a rule, there is a problem with system files, either they are damaged or completely lost. Try the tips below, all tips are given for Windows XP.

The first case (the computer turns on, but the OS itself does not boot).

1) Use the “Load last known known configuration (with working parameters)” option. You can use it as follows: after turning on the computer, press the F8 key, a window will appear, and in it select the above-mentioned menu item.

2) Enter safe mode and try to restore the computer to its previous state. To do this, when booting the computer, press the F8 key (as in the previous paragraph), select “Safe Mode”.

If the system boots, go to the following path: Start -> All Programs -> Accessories -> System Tools -> System Restore. And following the wizard's prompts, try to restore an earlier working system.

3) If the previous methods did not help, then I suggest you familiarize yourself with another option. This option will return your computer to working order with a 99% probability. What do we have to do? You just need to update the old system.

To do this, you will need a boot disk with Windows XP. Insert the disc into the DVD-ROM, reboot, it should boot from the CD, for this you need to set the appropriate item in the BIOS, or you can call up the boot option menu with the F12 key when booting the PC and select boot from CD/DVD-ROM, but This method may not be suitable for everyone.

After booting from the CD, select "Install Windows XP" following the prompts. When a window appears notifying you that a previously installed OS has been found, press the R key. This way, the Windows installer will update the existing copy.

Wait until it finishes and try to boot normally.

The second case (the computer does not turn on at all).

In fact, there can be a lot of reasons for this, and it can sometimes be very difficult to help in absentia in this case. And, as a rule, the reason is a malfunction of some device (motherboard, power supply, RAM, etc.).

At home, especially for an inexperienced user, there is simply no way to check the functionality of a device by replacing it with a known working one. But there is a way out, although not 100%.

First . Try resetting the BIOS. To do this, you need to remove the battery for a few minutes. Or close the jumper contacts to reset the BIOS. Look for a jumper next to the battery labeled Clear CMOS (possible designations: CCMOS, CL_CMOS, Clear RTC, CRTC, CLRTC, CL_RTC). If it doesn't help, read on.

Second. It is necessary to disconnect ALL devices on the computer, leaving only the motherboard connected. That is, we take out the video card, all RAM slots, disconnect the hard drive and DVD-ROM from the power supply, if there are additional devices (internal modem, sound card, etc.) we take them out, leaving only the motherboard connected to the power supply.

And now we try to turn on the computer, if it turns on, then the problem is in one of the disabled devices. Turn off the computer and try to connect the devices ALTERNATELY, checking the computer for functionality. First, connect the most important devices (video card, hard drive, RAM), and then the secondary ones.

Thus, if, when installing a device, the computer stops turning on, you can independently determine the faulty device. If the computer does not turn on with one motherboard, then the problem is either with the motherboard itself or with the power supply.

A common but frightening problem for users is when the computer turns on, but the operating system does not start. At the same time, the coolers work, the system unit makes noise, but the greeting and desktop are not visible. In fact, the recovery process can be done independently, and it is not as long and complicated as it seems at first glance.

Reasons why your computer won't boot

Malfunctions look different:

  • black screen with inscriptions - physical or system errors;
  • blue screen - problems with RAM or drivers.

There are malfunctions on different computers: Lenovo, Samsung, Msi, Asus and so on.

There are two types of reasons:

  • Physical- due to the computer hardware: rusty contacts on the boards, broken wires, poorly inserted video card, damaged hard drive, dried out thermal paste, dusty processor. There may be very simple reasons, for example, the monitor is not connected.
  • Software- the mathematical algorithm of the system is broken: incompatible drivers, viruses are installed, the user accidentally deleted files necessary for work, Windows is out of order, problems with the video driver.

Safe mode

When you simply restart the computer, pressing the Restart button on the system unit automatically restores the system.

If this does not help and the operating system does not start loading, it is advisable to turn to Safe Mode.

This is a way of operating a computer when it loads a list of necessary components without unnecessary elements.

  • Remove all information media from the computer: flash drives and disks.
  • In versions of Windows 7 / Vista / Windows xp / 2000 / ME / 98 / 95 - immediately after turning on, press F8. In Windows 8 / Server 2012 / Server 2012 R2 / 10 / Server 2016 - a combination of Shift and F8 at the same time.
  • Select Safe Mode.
  • Sign in.

F8 restores the version of the operating system to the previous changes.

Example

You can load the Last Known Good Configuration of Windows 7 like this: F8 or Del - Last Known Good Configuration (Advanced).

The mouse does not work in this mode; control occurs through the up-down and Enter buttons.

Damaged HAL.dll

The following steps will help fix the error when the computer reports that the HAL.dll file is damaged or missing, and restore the operation of the OS:


Startup recovery

Checking the monitor, components, connections

The external condition of the device is important.

Perhaps the reason is hidden in external damage:


After turning on the computer, a squeak follows - a Bios signal. In normal condition, this is one short “squeak” and the computer boots. If there is a malfunction, the sound changes. It is important to know the name of Bios and count the number of signals. This way you can figure out the problem using the signals.

Video card driver conflict

The computer cannot turn on due to installed video drivers. In this case, go to Safe Mode - Start - Control Panel - Device Manager - Video adapters - Disable/Update drivers (program conflicts are visible here in the Properties - Resources tab).

In some cases, after updating the drivers, the problem disappears.

Removing programs that block OS loading

From time to time, programs that conflict with Windows cause a malfunction. It is advisable to correct the situation through Safe Mode:

Start - Programs and Features - Uninstall a program - Uninstall.
You can delete in Safe Mode using CCleaner.

Disabling unnecessary Startup items

Safe Mode - Start - In the Start command line, enter msconfig.exe and press Enter - In System Configuration there are 5 tabs:


If the problem disappears, you need to go into Safe Mode and add one program at a time to startup in the “Services” list and restart the computer in normal mode.

As soon as the problem returns after adding another program to startup, the root has been found, but this program must be disabled, updated, or deleted altogether.

To enter the normal Windows operating mode: In the “Start” menu, write “msconfig.exe” and press Enter - System Configuration - General - place the checkbox on “Normal Startup” - Click OK and restart the computer.

Reverting the system to working condition

Via F8 go to the menu.


Infinite reboot

The reason that a computer or laptop does not boot beyond the manufacturer's screensaver is an initialization failure, an emergency power outage, or a full disk with files (movies, photos, etc.).

When the computer turns on again after “Welcome”, you need to:

  • restart your computer several times;
  • hold down F8 - the Advanced Boot Options window will appear - go to Repair Your Computer - Enter
  • if the endless startup to the logo continues: Safe Mode - My Computer - drive C - copy and move files to D.

If the startup repair tool cannot automatically restore the system, you need the help of removable media.

Using a Live CD (Boot Disk)

The boot disk with the image is the second operating system. It contains a recovery console and will help in solving the problem.

Disc functions:

  • diagnostics;
  • virus checking;
  • useful utilities.

Many errors, for example, 0xc0000098 when starting Windows 7 (problem with starting files), are solved using boot disks.

Boot Manager Recovery

If there is an initialization error, the system does not see the hard drive. You need to start from the boot disk.

Press R - the console appears - enter “chkdsk c: / f /r” and press Enter - then enter “Bootrec.exe / FixMbr” and Enter - then “Bootrec.exe / FixBoot”.

So the commands restored the resume bootloader.

Overwriting the sector Bootrec.exe/RebuildBcd will work if the hard disk is intact.

If “NTLDR is missing” (file access is not complete), it is advisable to try to restore boot records. If this does not help, copy the file from the disk to the system partition with the command: E:\i386>copy ntldr C:\ - Enter, reboot and the system is restored.

MbrFix utility

The program is included in Hiren's BootCD. After starting MbrFix, enter into the command line: MbrFix.exe /drive 0 fixmbr/ win 10

The described option is suitable for Windows 10. Helps if the boot manager is missing or damaged.

4MRescureKi

Includes services for copying data, preparing for reinstallation, diagnosing problems in a hard drive, and checking for viruses. Works on Windows and Linux.

Viruses

Malicious programs are also the reason why the monitor stopped turning on. It is necessary to detect the infection and clean the device. It happens that a virus contains a game or a picture from the Internet. An anti-virus scanner is required, which is loaded before the operating system runs.
Antiviruses on removable media are good: disks and flash drives. They have their own boot records and menu interface. For example, Avast and Kaspersky are excellent at resuscitating “sick” files.

Reinstalling the system

If the previous methods have been tried but failed to fix the problem, reinstalling the operating system is an option to solve the problem.


Black screen when reinstalling Windows

The reasons for this situation are:

  • Unsuitable Windows, in this case you need a different operating system.
  • Bad sectors of the hard drive, damage to the storage medium from which the OS is installed.
  • It is recommended to install the operating system on another partition of the hard drive.

The hard drive has failed: how to determine and what to do

If you suspect that your hard drive is not working, it is important to carry out diagnostics. If you format it, the saved files will be lost.

It is advisable to check the hard drive in several ways:


Signs that the hard drive is completely broken:


Useful video

A computer is a technology that has become simply a necessity for modern people. But even with careful and attentive use, there are often situations when the computer may break down, for example, suddenly stop turning on. Most modern users will not understand the reasons and will contact a technician or take the equipment to a service center to diagnose the problem and subsequently repair it. But often you can cope with problems yourself, without shelling out significant sums for repairs.

Therefore, it’s worth figuring out why the computer turned off and won’t turn on.

Causes of problems

In fact, there are a lot of reasons that cause PC problems. Repair of the fault will depend on correct diagnosis. First of all, you should try to determine the nature of the breakdown, and only then call a specialist, because some breakdowns can simply be resolved on their own.

Some of the most common problems that cause this include:

Each reason requires a separate approach and repair. For example, if the problem is with the electricity supply, then you can try to fix it yourself.

Computer power supply

If when you press the corresponding power button, the system unit does not respond at all, then most likely the problem is caused by a lack of power. If there is electricity in the room, then it is worth checking the connection of the surge protector itself to the network. Sometimes the protection in the surge protector is triggered. This situation is not uncommon if a large number of devices are connected to it.

Sometimes the reason for the lack of power is the cable. You should check its connection directly to the outlet, as well as to the connector on the system unit.

If after such a simple check the problem cannot be resolved, you should also check the power supply button, which is located near its socket. It should be in the on position.

Malfunctions in the power supply

Often the computer does not work due to a malfunction in the power supply. Sometimes this indicates a problem with it, and sometimes the device’s protective system against power surges is simply triggered. If there is a failure or voltage drop in the electrical network, the power supply will naturally react. The following signs will indicate a malfunction in the power supply:

  • when turned on, there are no reactions in the system unit;
  • When you press the start button, the indicators light up, but the reaction of the other components is not observed.

If the power supply is simply blocked and protected, then you can reset the corresponding capacitor on your own. To do this, just remove the power cable and the corresponding socket, wait a while, insert it back, and try to start your equipment again. Other types of malfunction of the power supply can only be confirmed by replacing it with another one that functions accurately.

Dusty system unit

Often the reason why the computer does not turn on is simple dust inside the system unit. Moreover, such a problem can manifest itself in various ways. The computer may turn off on its own during operation or may not start at all at the very beginning. The procedure for cleaning the system unit is as follows:

Battery problems

Each board contains a small 3V battery. It powers a special CMOS memory where the BIOS settings are located. If the device has been in use for a long time or has been left idle for a long time, the battery may run out. The problem with a dead battery is detected in the early stages: during daily startup, the date and time are lost. But there are situations when the computer does not turn on at all due to a faulty battery. Replacing the battery is quite simple, especially since they are on sale in many stores today.

Start button broken

If the button does not completely close the contacts, then, naturally, the computer will not turn on. It will also be easy to eliminate such a breakdown. It is necessary to find the area on the system board where the wires from the power button are connected, and then find the Power connector, which will be located nearby. The connector itself should be removed, and the two contacts responsible for turning it on should be carefully closed with a simple screwdriver. If after this the equipment does not work, you should look for something else for the reason.

Problems with the motherboard

If, after checking all the considered options, inclusion does not occur, then the conclusion is sad. It turns out that the computer does not turn on due to failures in the motherboard or its components. Here, only a person with special knowledge and skills can carry out independent repairs, so it is better to go to a specialist.

Most often, you will need to install a new motherboard, and it is not cheap. Most likely, you will want to purchase a motherboard of a more powerful and new model, so most likely you will also need to replace the processor and RAM strips. It would be more correct to say that the update will affect the entire system unit . If you decide to change only the motherboard, then it’s worth remembering that it must have:

  • for the processor, similar to the previous model;
  • hard drive connection interface;
  • the required number of connectors for RAM sticks of the same type;
  • the required number of slots for existing cards.

Another point worth remembering when purchasing a motherboard with a different set of system logistics is that the operating system will need to be replaced.

It makes sense to restore the motherboard if it is still under warranty, and also when the cost of work is no more than 30% of a new spare part.

Failure to load operating system

Sometimes the question arises: why does the computer turn on, but the OS does not load? In certain cases, the reason is with the system itself, and sometimes it is a consequence of the fact that the components on the device have malfunctioned. In a situation when after starting the system everything works, and a lot of inscriptions pop up on the screen in white and black, there are several options:

If this is the reason that the computer does not turn on, then the problem can be easily solved using a boot disk . It will help you restore or install a new operating system.

These are the main types of breakdowns that cause the computer to not turn on. As you can see, not every one of them requires the help of a specialist. Many of the problems can be easily dealt with on your own.

The first step is to establish the cause of the malfunction. If the situation is such that the computer turns on, but then the operating system (OS) itself does not load, then naturally you need to dig towards the same OS.

And if the situation is that the computer does not even turn on at all, that is, it shows absolutely no signs of life, then the situation can be much worse.

A few recommendations on what to do if your computer won’t boot!

There is probably no need to explain that situations when the computer does not boot occur quite often. There may be a myriad of reasons that led to this. Now we will try to figure out why such situations arise and how to deal with them. Let's look at desktop computers rather than laptops, although in some cases the methods for solving the problem may be very similar.

Causes of download problems

First of all, in the question of why the computer does not boot, you need to understand that among the main reasons there are two main ones: physical damage to the components of the computer system and a malfunction of the software (in this case, Windows).

Both can cause serious problems. Let's look at the most common causes of failures and figure out how to eliminate the consequences.

Consequences of physical impact

As for damage to physical components, first you should pay attention to the initial stage of booting the PC. Probably everyone knows that when turned on, the system unit makes a characteristic sound (a single squeak). This indicates that all hardware components are in order. True, this is not always the case. The fact is that a hard drive failure is detected only after startup (the system does not see it).

Sometimes the system speaker may emit short and long squeaks. This is already worse. This can only mean one thing - some component is not working, has failed, or is simply incorrectly connected to the motherboard. The signals may vary for different BIOS versions. But all of them may indicate malfunctions in the operation of RAM, video card, central processor, etc. In some cases, there may be no signal at all.

In this case, it is recommended to remove the system unit panel and check whether all components are connected to the motherboard. It may well be that the device does not work not because of failure, but because the corresponding cable is damaged. Naturally, it is not possible to determine such a malfunction yourself, so you will have to turn to specialists.

There are often cases when the computer does not boot even when turned on. There may also be enough reasons for this. It is very likely that there is simply no power supply. It is worth checking the outlet or uninterruptible power supply. Sometimes, when a large number of electrical appliances are plugged into an extension cord, protection and much more may be triggered. You can check the battery that is installed on the motherboard. It is very possible that after replacing it, turning on and booting the computer will go as usual. Often no one pays attention to this, nevertheless the fact remains a fact.

In general, you should immediately check all cables, sockets, extension cords, etc. Maybe this is really the reason. That’s why it turns out that nothing starts, nothing loads, the computer is black and shows no signs of life.

Crash systems

Of course, you can replace the hardware, but with the operating system itself the situation is much worse, because no one obviously wants to reinstall the system, format the hard drive or partitions, which will entail data loss.

There are just a lot of reasons why Windows might crash: a sudden power outage, incorrect shutdown or shutdown, a software failure, the presence of viruses, damage to the hard drive, etc. The list is endless.

As for physical damage to the hard drive, the severity of the problem can only be determined after full testing of the surface and contacts. If it burns out, you know, you’ll have to shell out money for a new one, there’s nothing you can do about it. If the damage is minor, you can try to restore the damaged sectors. This will be discussed a little later.

Basic methods to correct the situation

As is already clear, in terms of hardware failure, when the computer does not boot, the black screen hangs constantly, the system unit does not make a sound, the solution would be a complete test of all components. It is very possible that reconnecting or replacing some of them will clarify the problem.

It is worth noting that in some cases, when the system does not detect the hard drive, the most trivial situation may occur. In the BIOS, the boot priority can be set to, say, CD/DVD/ROM first, the second device is a USB drive, etc. It is clear that when media of this type is inserted, the system will display a message stating that this is not a system drive.

It also happens that the computer does not boot from the Windows installation disk. Here you will have to check the disk itself. It is very possible that there are some scratches or other damage on it. By the way, perhaps the drive itself is damaged and simply does not work.

Now a few words about how to correct the situation when the computer does not boot, Windows 7 does not start, and in general it seems that nothing can be done.

Let’s say right away: don’t despair and panic. Bill Gates is not a stupid person at all. When creating his system, he left loopholes to restore the functionality of the operating systems, and today there are quite a lot of methods that allow you to quickly and effectively apply measures that can, so to speak, breathe new life into the system. Below we will describe the most common problems and methods for eliminating them specifically from the point of view of the Windows software shell.

Loading Last Known Good Configuration and Restoring the System

As a rule, even after very serious errors in the operation of Windows 7, as they say, it simply does not give up. On reboot (if everything is fine with boot records), testing occurs, and then in most cases a message is displayed about possible boot options, including loading the last known known configuration.

This happens because the system, as it were, remembers its last working state and offers to go to it, bypassing all the changes made before. In 90% of cases this helps. However, it also happens that the computer does not boot even if Windows self-healing, and the user eventually receives a message that such a configuration could not be loaded.

The same applies to using system restore, which may be offered when Windows starts. Sometimes it helps, sometimes it doesn't. In principle, both services are very similar. In this state of affairs, more effective measures will have to be taken.

Safe mode

Many users, faced with a problem, for example, when the computer does not boot after updating Windows 7, clearly underestimate the benefits of safe mode, but it allows you to gain access to a fully functional system and fix many software errors.

To load safe mode after the system starts, you need to press and hold the F8 key. When the system boots, we can take care of our problem. In this case, you can check all the hardware components for functionality and the presence of the appropriate drivers, run a disk check for errors, and finally begin restoring the system.

System Restore

First of all, using the control panel, you need to go to the “Backup and Restore” section. It can also be accessed from the main Start menu under All Programs/Maintenance. Here you need to select a checkpoint (the last one created or one of those present in the list) and start the process itself. This, of course, can take quite a lot of time, but if you don’t want to reinstall, you’ll have to be patient.

Now let's say that after the updates the computer does not boot. In the same control panel, if you go to Windows Update, you can view the update log, in which, in fact, you will need to delete everything that was installed before the system crash, no matter whether these updates were installed automatically or in manual mode.

In many cases, this approach allows you to revive Windows without resorting to more serious methods, which not every user can handle.

Using the Recovery Console

If the above method does not produce results, you will have to use other methods. One of the most effective and radical methods when the computer does not boot is to use the recovery console, which is available either on the Windows 7 installation or emergency recovery disk.

To use such disks, of course, you should make the appropriate boot priority settings in the BIOS, indicating the CD/DVD-ROM first in the list.

The boot menu will show a "Welcome To Setup" screen, after which you will need to press the "R" key to go directly to the console (command line). It is worth considering that if more than one operating system is installed on the computer, folders with files will first be shown, and then a request will follow which system the user wants to work with. Now you just need to enter the number corresponding to the number of the selected system. Next, you may be asked to enter the administrator password, provided that you have one. Now about the teams. What and how to enter and what to use, we will now figure it out.

Recovering the Boot.ini file

As a rule, one of the reasons for a system crash is damage to the Boot.ini boot file, which is responsible for loading the system. To restore it, almost all systems use a tool called Bootcfg. Bootcfg/Rebuild is entered on the command line (not counting other tools for scanning its entries, redirecting actions, adding identifiers, etc.). It seems that, apart from the main recovery command, the average user does not need anything else.

Recovering the Master Boot Record

The master boot record contains tables of all logical partitions of the hard drive. The so-called primary loader places the active and boot sectors in the tables, after which, in fact, the system starts. If the boot record is damaged, the active sector simply will not be able to start the system.

To restore in this case, use the Fixmbr command, after which you enter the qualified name of the disk or partition. In the case of drive C, the command will look like Fixmbr\Device\HardDisc0.

Recovering the boot sector of the hard drive

The boot sector is a small partition on the hard drive for storing data in FAT32 or NTFS file systems for booting. If it is damaged, use the Fixboot\c: recovery command (provided that the operating system was installed on drive C).

Quick system reinstallation

Again, let's consider a situation where, after updating Windows 7, the computer does not boot, and the system simply does not want to start. As a last resort, you can use the so-called quick reinstallation of the system in the same folder where the previous OS was installed. In some cases, this may correct errors.

After the system starts from the disk, the license agreement window will appear. You can agree to the terms by pressing the F8 key, after which you will be asked to select an installation method. Key "R" - restore the existing version, Esc - cancel the restoration and go to a new installation. In most cases, recovery proceeds without problems.

Virus check

Now a few words about another unpleasant situation, when the system does not start and the computer does not boot. A black screen may be the result of spontaneous viruses that either prevent the system from booting or change boot records.

In this case, it is recommended to use utilities such as Kaspersky Rescue Disc or Dr. Web Rescue Disc. As is already clear, such programs start directly from the optical disk, but, what is most interesting, they are loaded even before the Windows OS starts. They have a graphical interface, so working with them is not difficult. It should be noted that in 99.99% of cases, such applications remove even those viruses that are simply impossible to remove using standard scanners installed on the system. After all, they can “hang” even in RAM. At the end of the check, the computer terminal is rebooted, and, hurray, the system works again as if nothing had happened.

Conclusion

So we looked at the question of what to do if the computer does not boot. It seems that some solutions to this problem will be useful to many users. Of course, it’s quite difficult to say right away, right away, why a computer or operating system won’t boot. But if you conduct a comprehensive test and find out the cause of the problem, then you can choose the most appropriate method to correct the situation.
