Almost all users know that some versions of Windows-systems at startup instead of the usual graphical interface can display blue screens. And it is not always possible to determine exactly why this is happening. To get started, just look if the blue screen when the laptop is turned on is the so-called death screen (BSoD) or is it something like a “Desktop”, but without controls. The second case is not as catastrophic as the first, because, quite possibly, the system is in a kind of standby mode for loading all the necessary components. But when the death screen appears (or when the elements of the "Desktop" are not activated at all), decisive measures will have to be taken.
Why does the blue screen appear once or continuously when I turn on the laptop?
As for the first option, partly such a failure may be due to violations in the Explorer service, which is responsible for starting the graphical interface.
If the blue screen is lit when the laptop is turned on , but the interface elements are not loading for a very long time, you can restart in safe mode and use the manual launch of the corresponding service by writing the command of the same name in the Run menu (Win + R) or using the “Dispatcher” tasks. " Then it will be possible to identify possible failures.
In the case of the death screen, a special stop code is usually indicated, a description of the failure and a link to the driver file (sometimes it may be absent). What caused this behavior of the system will have to figure out on their own. But most often, the appearance of a blue screen when you turn on the laptop is associated with the following reasons:
- damage to system components;
- incompatibility of new equipment with the system;
- malfunctions or overheating of equipment;
- problems with drivers;
- conflicts with installed software;
- incorrectly set BIOS parameters;
- exposure to viruses;
- malfunctions of protective programs.
Interpretation of errors on a blue screen after turning on a laptop or desktop PC
A few words are worth mentioning about quickly identifying the causes of the failure, in which the screen of death appears. You should immediately look at the error description and stop code. Depending on this, it will be possible to take appropriate measures. If a failed driver file (usually SYS format) is specified, the solution will concern just such a component. Sometimes it happens that a blue screen appears when you turn on the laptop, but after a while, or even when you restart, it disappears.
You can determine the malfunction using the special utility BlueScreenView, in which after clicking on the AppCrashView link it will be possible to identify a failed component. Then it will immediately become clear what exactly affected the appearance of the failure.
Restoring system performance with simple methods
But we will proceed from the fact that the user does not have such a program at hand, and a laptop or computer constantly gives an error. In this case, when you turn on the computer device, you can try to remove the blue screen by using the special start menu, which is called up by pressing the F8 key at the very beginning of the system boot.
In it, you need to select the start of the last working configuration. If this does not work, you can try to force shutdown and turn on the terminal several times so that the system recovery works automatically. Also, as an option, you can use the start in safe mode, and then either restore the system from a special section, or do diagnostics of computer components.
Checking the main components of a computer
As already clear, the blue screen after turning on the laptop or desktop computer may appear due to problems with the equipment. But first of all, you should check if there is enough space on the hard disk (in the system partition). If anyone does not know, for the normal operation of Windows on disk "C" free space requires at least 10% of the total size of the partition in which the operating system is installed. Thus, excess computer debris must be disposed of.
But the “iron” components can also affect the appearance of a blue screen when you turn on the laptop. We do not take hardware diagnostic methods into account, since it is unlikely that somewhere there is a loose contact, but to check their work, if you can use a safe start for downloading, it is necessary. This primarily concerns the testing of the processor, RAM and hard drive.
It is better to use third-party programs for the CPU, but to check the RAM, a utility built into the system (mdsched in the execution console) is suitable. It is better to check the hard drive not by regular means, but through the command line (toolkit of the CHKDSK command with additional attributes like the combination “/ x / f / r” without quotes). To test system components, absolutely all experts advise using the sfc / scannow command.
Driver Actions
The main failures with the appearance of a blue screen when the laptop is turned on, the system owes just drivers. In most cases, this applies to the management software for video cards, since they are involved in the system boot.
In this situation, the driver must either be updated or the device removed completely and rebooted. If the reason is a failed updated driver, you should roll it back. For an update it is better to use automated programs like Driver Booster, but in this case you need to boot the system in safe start mode with network drivers. To restore the old version of the driver, the usual “Device Manager” is also suitable.
Software Compatibility Issues
Sometimes, although infrequently, the cause of this phenomenon may be recently installed software, which is incompatible with the operating system itself or with the equipment used.
In the best case, experts recommend using activation of the program’s executable file launch in compatibility mode through the properties of the shortcut, in the worst case, completely remove the application with all its components. But for this it is advisable to use highly targeted applications like iObit Uninstaller, and not the “native” section of programs and system components.
The same situation can be observed with updates. In some cases, it helps to remove the last installed packages one by one, with a reboot, manually searching for updates, and then excluding failed updates from the installation list.
Note: To simplify the operations you can use the Show or Hide Updates program.
BIOS settings
Another common reason for the appearance of a blue screen when the laptop is turned on is incorrect BIOS settings, overclocking and obsolescence of the primary system firmware, due to which it does not recognize new equipment.
To get started, it is better to perform a complete reset, using a menu item such as Load Setup Defaults. But updating the BIOS firmware without special knowledge on its own is not recommended. In the best case, if you have installed the UEFI system, the update can be performed directly from Windows, but the installed firmware should fully correspond to the chip manufacturer and the developer of the corresponding software.
Viruses and Security Software
Finally, a few words about viruses and antivirus software. The fact that viruses can cause such phenomena does not surprise anyone. It goes without saying that the system should be checked for threats. If downloading is not possible in any of the modes, you can advise using the Kaspersky Rescue Disk program, which, when recording to removable media, allows you to boot from it. But, no matter how strange it may sound, the antiviruses themselves are no less capable of provoking the appearance of blue screens. A vivid example of this is the vaunted free antivirus Avast !, for which such flaws are noticed. It should be removed completely and completely, using the “native” developer utility or uninstaller programs for this, and then installing other security software.
