Even after installing the newest and most advanced operating system, in case of failure, solving problems with a computer still requires user intervention. One of these problems arises when the computer restarts endlessly on startup... This is one of the most annoying problems you can face.
Most of us are so dependent on the computer that when it stops working, we fall into despair from hopelessness. Don't panic - know that a constant reboot at system startup is not the end of your beautiful computer, it is a temporary problem that can be overcome.
Why does your computer restart after startup? What could be causing this behavior? How to determine possible solutions this problem?
When the computer restarts on its own, the problem may be hardware or software related. The solution to the problem is difficult due to the fact that the operating system cannot boot itself. Below are the possible reasonswhy the computer restarts on startup.
The presence of viruses
One of the most common reasons that can lead to a situation where the computer constantly restarts at startup is viruses. After viruses get into a computer, they usually come to full "alert" just the next time the computer is turned on or restarted.
For Windows 7, Windows Vista, and XP, one of the solution options is to boot the operating system into Safe Mode or in mode Last working configuration... To access the mode selection menu windows boot, immediately after turning on the computer, press the F8.
If Windows booted into Safe Modethen update antivirus software, download and install latest updates OS, and then scan the system for malware... Also be sure to see Autostart operating system. It is in this section that shortcuts for launching malicious programs can be installed. Here is a very useful utility Autoruns.
For most operating systems of the Windows family, one of the methods is to boot from the CD with the licensed version of the installed OS and turn on recovery mode... also in Safe Mode performance can be restored by rolling back the OS state to an earlier one restore pointwhen the computer worked properly. But this will only work if the creation of restore points was enabled for another working system... After restoring the start of the operating system, immediately install the antivirus and check your computer for viruses!
If this method did not help, and the virus caused an irreparable windows malfunctionsthen you will have to format the disk and reinstall the OS completely. In order not to lose important data, you should first connect your hard drive to a working computer with installed anti-virus protection and copy the necessary information.
Hardware problems
Another reason when the computer restarts cyclically at startup is a hardware problem. The main problem in this case may be with the hard disk, due to the failure of the boot partition. Winchester should be checked special program HDD diagnostics ( Victoria or MHDD) and, if there are errors, try to eliminate them. If the damage to the hard drive is not resolved with these utilities, then the hard drive will most likely need to be replaced with a new one. Of course, this is due to the subsequent installation of the operating system again.
Also, a malfunction may result in a reboot. random access memory... To check for errors in RAM, there is a very easy and understandable utility Memtest86 +... If the error is in memory, then it should be replaced with a good one.
A damaged video card can also cause Windows to restart. Follows in Safe Mode Windows remove the video card driver and after reboot. If the malfunction of the video card is not eliminated, you should contact the workshop for its check and repair.
Overheat... This may be due to fan failure, dust accumulation. Unless you are a computer repair technician, it is not recommended to open your computer and break the warranty seals. Take your computer to a workshop for complete cleaning vacuum cleaner and restore the fans to working condition.
In any case, the solution of hardware problems should be entrusted to competent specialists. This will save time and other problems that you can create yourself with your unqualified repair.
BIOS problem
A spontaneous restart of the computer may be associated with BIOS... The BIOS problem, although quite rare, can be eliminated immediately and easily. Should throw off bIOS settings to default settings and reboot. If this does not help, then it is required update BIOS... The most latest version can always be found on the manufacturer's website.
Incompatibility software or drivers
There is one more reason that can cause the computer to restart. Installation of incompatible software and drivers quite often leads to the fact that the System cannot start correctly. Full reinstallation of drivers in Safe Mode, will help solve reboot problems. If the installation of any program led to this problem, then it should be removed in Safe Mode. Also, rollback of the system to an earlier state can help here.
For windows users there is one very handy feature. You can simply turn off automatic restart when a fault occurs.
To do this, press right click mouse on the icon My computer and select the item " Properties". In the appeared window “ System properties"You must select the tab" Additionally"And in the section" "press the button" Options…". In the "" window that opens, uncheck the " Perform automatic reboot».
Now, when a critical error occurs, the computer will not restart, but will stop in the screen of death ( BSOD). In this case, you will see an error code on the screen, by which you can find out the reason for the refusal.
These were the most simple ways self-service recovery of Windows. All further methods require a much deeper knowledge of the computer, and therefore you should consult a computer wizard here.
Windows 7 Professional (64-bit) pumped updates, started installing them and went into a cyclic reboot for 35% of updates. There was no way to get out of this vicious circle.
Treatment through rollback to the last successful copy and auto-recovery from the installation windows disk didn't help.
In the end, the following helped.
We just need access to the file system - we need to rename several files. There are several ways to do this.
You can press F8 at startup, select "Troubleshoot computer problems", enter the administrator login and password if asked and select "Command Prompt".
If the administrator's logins and passwords are lost, then you can take out the hard drive, connect it to a working Windows machine and do everything in a familiar environment. Or boot from some Life-CD, as long as the FAT32 and NTFS file systems are supported. There is, for example, MSDaRT (this is ERD Commaner, completed to Windows 10) or Dr.Web LiveDisk.
So we got to file system. First, let's decide on the drive letter in order to treat exactly the "Windows" that we need, but not to break the "Windows", which is on the working machine in which you turned on the hard drive from the "flying" machine or something else. The easiest way is to go to the Users directory (at the root of the disk) and see the list of users, or just climb through the directory tree and see what is there as of the date the files were created. Have you decided? Now we start to heal.
Let it turn out that our system is on the C drive:
Then on the command line we write:
C:
cd windows
ren SoftwareDistribution SoftwareDistribution.old
cd winsxs
ren pending.xml pending.xml.old
ren reboot.xml reboot.xml.old
cd .. \\ system32
ren catroot2 catroot2.old
cd config
dir Regback
Note 1. I didn't have a pending.xml file, but it could have been ... so we still execute all the lines. These commands renamed the interfering files and directories - they now have .old extensions, so if something happens, you can rename everything back.
Note 2. Several sources limited it to this, but in my case it did not help - it was also necessary to restore the registry.
Further. Make sure that the list that the last command issued contains the “system” and “software” directories. And we execute 4 more commands (we restore the registry from a copy, having previously saved the old non-working one, just in case):
ren system system.old
ren software software.old
copy Regback \\ system system
copy Regback \\ software software
And we exit the command line with the last command:
exit
We reboot. Everything went well for me - Windows booted. Then I turned off the Windows Update Service (Start -\u003e Control Panel -\u003e System and Security -\u003e Turn on or off automatic update) and rebooted to be sure.
In an amicable way, after all this, you need to re-enable this service and install all updates - go to Windows Update in the Control Panel and reinstall all updates that have a checkmark. I didn’t dig into this for some reason, so I will not describe it. But I do not advise you to neglect this, especially if there is no antivirus ...
This method of recovering from an unsuccessful installation of updates can help when standard methods do not help. 35% is most likely a particular - someone may have other numbers. Although I met 35% several times while looking for a cure - perhaps this is a feature of some Windows update.
If you turn on the computer, and it suddenly restarts, barely having time to show the startup windows screen - it's not very pleasant. If this happens all the time or your PC generally refuses to boot properly, you need to urgently take action to "cure". The main problem is that the computer can behave this way for a variety of reasons.
It is difficult to immediately and unequivocally understand exactly where the source of such "lags" lies. But there are a few more likely options to check first. It:
- overheating for a variety of reasons;
- newly installed new equipment;
- poor contact of connectors and plugs;
- problems in the operation of the power supply;
- crashes in software.
Now let's look at all the options separately, starting with the components of Windows itself.
Reboots due to a crash in the OS
If your PC started to restart constantly at startup, you should contact boot disk with the operating system. If you don't have one, you can always borrow it from friends or download the official trial version Windows and burn to blank DVD.
So, the disk is there, and the computer still restarts immediately after the Windows welcome screen. Objective: Boot from DVD and do some operations. It is worth noting that if the computer reboots every now and then, this method should be tested first, but it does not help too often. In any case, you should try, especially if the disc is at hand.
To start from DVD at the first boot screen (where information about motherboard, hard drives and RAM), press F12. On most computers and laptops, it displays a boot priority screen where you need to select a Windows disk (or a USB flash drive, if you are).
When booting the OS from the media, the "Recovery" button will appear on the first screen.
You need to click on it. If a question appears about reassigning drive letters, answer in the affirmative, and then select your version of Windows installed from the drop-down list.
The picture is just an example. Your computer will display this information slightly differently.
On the next screen, you need to select "Startup Repair" and just wait for smart Windows 7 to independently explore possible options for fixing boot errors.
It may or may not help. If that doesn't help, there is another option. Follow the previous steps, only this time use the "Command Line" item (the one below).
Depending on which disk your installed Windows, enter that letter with a colon and press Enter (C: - for drive C). Then use the commands in order:
- CD \\ windows \\ system32 \\ config
- MD backup
- copy *. * backup
- CD RegBack
- copy *. * ..
Reboot. At the next boot, everything should be OK. If not, then the computer does not restart at all due to the operating system.
Finding other reasons
If the PC restarts when the OS starts up and does so constantly, the first thing to think about is the notorious overheating. Still, the computer also requires care and without proper care, sooner or later it will start to malfunction. At the very least, you should clean it from dust, change the thermal paste on the processor, pay attention to whether the coolers rotate well. Maybe they should be replaced with new ones, or at least change the oil in them.
Don't forget about the video card. It also has its own processor and heatsink. The first may have dry thermal paste, and the second may become clogged with dust. The cooler on the card can also stop.
By the way: think about how your system unit is located. If it is near a hot battery or is actually in an enclosed space on a computer desk, then this can also cause overheating.
What other options are there? The first thing that can be done if the computer often restarts at bootup is to check all the contacts, wires, plugs, connectors. You never know - suddenly one of them does not fit snugly. And we are talking about the connectors on the hardware itself - the motherboard, for example. Something at startup may interfere with normal system boot.
Overheating can also occur in the power supply. It is better not to disassemble it yourself, but take it for repair. It is better to replace the defective one with a new one of appropriate power. Finally, if the PC started randomly starting a restart just yesterday or today after installing a new hard drive or video card or even a printer, try turning off this equipment and turning on the computer without it.
The first part of the article tells about the reasons for restarting Windows 7. The second part describes in detail how to solve the problem of systematic restart of Windows. There are also other ways to solve the problem.
Reboot reasons
It is impossible to completely avoid errors in the operation of a computer system. Sooner or later, all users are faced with the need to troubleshoot the OS.
A very common problem is when, after updating, windows 7 reboots constantly and spontaneously. The reason lies in the malfunction of the hardware or software component of the computer.
The most common reasons for an unscheduled restart of Windows 7 are:
Video: Updating Windows 7. Errors and Solutions
What to do
First of all, you should use the services of a service center, or diagnose the computer yourself.
One should start by studying the software side of the problem. Most often, software problems are associated with viruses, or with the latest installed system updates.
The following is the most common reason for restarting Windows 7 and effective method her quick fix.
Remove update KB971033
Installation Center windows updates - a utility that allows users to install all the most latest drivers and system updates. However, sometimes the operating system personal computer and the center-mounted element may not be compatible
To date, one of the most problematic updates to Windows 7 is the KB971033 component, which, in most cases, disrupts the computer's operating system.
To uninstall an updateKB971033 should adhere to the following actions:
Activating Windows
After uninstalling the KB971033 update, you need to reactivate the Windows 7. To do this, you need to install a special activator for Windows 7. It can be downloaded from many web resources.
Important! Before installing the activator, check the file for malicious content with an antivirus.
To activate the OS, follow the instructions:
We close access for updating KB971033
The next step is to close access for updating KB971033, so that in the future you will not again encounter system failures.
The process of closing access to the KB971033 update looks like this:
Other solutions
Apart from the situation with the KB971033 component, there are many other reasons for the systematic restart of the computer.
Let's consider some of these reasons and methods of solving them:
- the case of a personal computer is too small for its contents. The solution to this problem is the urgent replacement of the case, because it should be remembered that a poorly ventilated case leads to the next more important problem;
- overheating of the processor and other components. main reason - insufficient cooling of the housing components. To fix the problem, open the computer case and clean the contents of dust. All fans should also be checked. In order to avoid problems in the future, install specialized utilities that monitor the temperature of the processor;
- weak power supply. Such a power supply unit cannot cope with the tasks set by the computer. This problem not very common, but still takes place. The solution to the problem is to replace the power supply;
- lack of RAM or its defects. Quite a common cause of system problems. To test the OP on your own, you can use a number of programs, but it is better to address such a task in service center... The solution is to replace the RAM module.
The article discusses most of the reasons for the constant restart of a computer running the Windows 7 operating system. detailed instructions for troubleshooting. It should be noted that you must first determine the cause of the problem as accurately as possible before you begin to fix the system problems yourself.
The most annoying problem for an inexperienced Windows user is a reboot problem. The essence of the problem is that the user cannot work normally on the computer, play, watch videos or visit social networks due to constant reboot of the OS. Let's take a closer look at how you can solve the problem when Windows is constantly rebooting.
Please note that the main reason for this phenomenon may be the banal loss of important system files. This happens through the fault of the user or viruses, although the latter also do not appear in the system by themselves. In order to return the system to a working state, you need to start or simply reinstall it.
Let's consider in more detail the situation with constant reboot on examples of different versions.
Windows 7 reboots at boot
The cause of an endless (cyclic) system reboot can be either a virus or a problem at the hardware level.
If the problem is a virus:
If the viruses are all removed or the download has not finished in safe mode, but on the contrary continues, then there is a problem with the hardware, in particular with boot sector hard disk.
If it is damaged, the system simply does not find the boot files and continues to reboot until it finds one. There are several options for solving this problem:
- Boot from boot windows flash drives with command line support. Enter the command: fdisk / mbr and press Enter. Reboot and check the results. Only then try the following options.
- Reinstall operating systemafter formatting hDD for installation (not to be confused with local drives);
- Try to move the user's files to another hard drive that works for sure, and then repeat step 1;
- Take it for repair or use a program that will restore boot partitionif at all possible. We can recommend: Active Partition Recovery, Testdisk, SFbootablecd. They must be loaded onto a USB flash drive (make it bootable) and start the computer from it. Then everything happens intuitively according to the instructions of the application that you select.
Other options that affect the correctness of the OS boot can be:
- Malfunction of the video card;
- Malfunction of the sector (s) of the RAM;
- BIOS failure;
- Dust in the system unit in large quantities;
- Overheating of the computer.
If booting in safe mode works, then the first three points are decided by the user independently. To do this, you need, in the case of a video card, to reinstall the drivers. The variant of a malfunction of the RAM is solved by checking the MemTest86 + program, which will show whether you can continue to use your RAM bar (s). BIOS failure is solved by removing the battery from system unit... It looks like a small penny.
This will create an automatic reset custom settings and the BIOS will return to its original state. In case of dust and overheating - if you do not understand how to clean your computer or change thermal paste, it is better to contact a specialist who will do everything neatly and without harm to your computer.
Windows 8 | 8.1 reboots by itself
In general, the problems of a more recent version of the OS, as well as in the "seven", have not gone away. The system can reboot on its own for several reasons:
- Important updates are being installed;
- There is a virus in the system;
- Memory problems, both on the hard drive, SSD, and RAM.
In the first case, of course, the user should be warned that the updates will be reinstalled now, but sometimes the user may simply not notice this message, and the system is already starting to reboot. As a result, important documents may be lost or online conferences disrupted. You need to closely monitor Windows 8 | 8.1 notifications to avoid this issue.
In case of a virus, use the advice from the previous subsection about Windows 7. If the system boots normally and without using safe mode, then before the next "reboot" make a scan of the Cureit! -program. This usually helps the first time, but it may take a few checks.
The third point is solved in the same way as in the case of Windows 7. In difficult situations with computer memory, it is better not to hesitate and contact a specialist, as well as be ready to buy a new hard drive or RAM stick.
Windows 10 reboots on shutdown
Problems with this system are very common, but they rarely spill over into endless repetitions. The menu bar can often disappear, "Start" or "Search" cannot be launched, but these are all temporary phenomena that are solved by rebooting and then installing updates.
What to do if the "ten" starts to reboot on shutdown? This can happen for the following reasons:
- Installing updates, updating system files;
- The presence of a virus;
- Hard disk problem;
- System incompatibility with the processing of dynamic processor cycles.
The first point assumes only patience from the user, because updates will be installed whether you like it or not. It is forbidden to disable updates in this system, because it is considered the last of its kind and should be updated regularly.
The second point and the third point are solved in the same way as in the case of Windows 7, and the last option is a little more interesting.
In order to disable the processing of dynamic processor cycles, you need to call " Command line with Administrator rights "and enter the command bcdedit / set disabledynamictick yes
