The situation is familiar to many: you press the power button, but instead of the usual Windows boot, a scary message appears on the screen. blue screen of death (BSOD) with a cryptographic error code. The laptop may freeze at this stage, reboot in a loop, or not respond to commands at all. The reasons for this behavior are varied - from driver failure to critical hard drive damage.
In this article we will look at all possible causes of BSOD when turning on the laptop, we will learn to decipher error codes and select working solutions - from simple reboots to complex hardware checks. We will pay special attention unique symptoms that help accurately diagnose the problem without contacting a service center. If your ASUS, Lenovo, HP or Acer refuses to load - read on.
What is a Blue Screen of Death (BSOD) and why does it appear when you turn it on?
BSOD (Blue Screen of Death) is the emergency screen that Windows displays when critical system error, preventing you from continuing to work. Unlike ordinary crashes, BSOD when turning on the laptop signals problems that even block the initial loading of the OS. Most often this is due to:
- 🔧 Driver conflicts - especially after updates or installation of new equipment (for example, Wi-Fi adapter or video cards).
- 💾 Damage to system files - due to sudden power outage, viruses or failure
NTFS. - 🔋 Hardware faults - problems with RAM, hard drive (HDD/SSD) or motherboard.
- 🔄 Incorrect BIOS/UEFI settings - for example, after overclocking the processor or changing the operating mode SATA controller.
The key feature of BSOD when enabled is cyclic reboot. The laptop can:
- 🔄 Boot to the Windows logo, then go into BSOD and restart.
- 🖥️ Show a blue screen immediately after pressing the power button.
- ⚡ Shut down a few seconds after the error appears.
In 80% of cases there is an error code on the screen (for example, CRITICAL_PROCESS_DIED or IRQL_NOT_LESS_OR_EQUAL) directly points to the source of the problem. However, if the screen blinks too quickly, you can use memory dump log (more on that in the next section).
- First time
- Rarely (every few months)
- Often (once a week)
- Constantly (daily)
How to read the BSOD error code and determine the cause of the failure
The blue screen error code is the main clue to diagnosis. It consists of:
- Error names (For example,
MEMORY_MANAGEMENT). - Stop code (hexadecimal number, for example
0x0000001A). - Recommendations for elimination (sometimes a QR code appears to download Microsoft tools).
Below is a table of the most common BSOD errors when turning on a laptop and their possible causes:
| Error code | Title | Probable Cause | Solution |
|---|---|---|---|
0x000000ED |
UNMOUNTABLE_BOOT_VOLUME | File system corruption, crash HDD/SSD or incorrect settings AHCI/IDE in BIOS. | Disk check via chkdsk, reset BIOS, replace SATA cable. |
0x0000007B |
INACCESSIBLE_BOOT_DEVICE | Driver conflict SATA controller, physical damage to the drive. | Updating drivers in safe mode, replacing SSD. |
0x00000050 |
PAGE_FAULT_IN_NONPAGED_AREA | Crash RAM, registry corruption, antivirus conflict. | Memory test (memtest86), registry restoration. |
0x000000D1 |
DRIVER_IRQL_NOT_LESS_OR_EQUAL | Incompatible or damaged driver (often network card or video adapter). | Removing the problematic driver via DISM. |
If the screen flashes too quickly to record the code, use one of the following methods:
- 📱 Take a video with your phone in slow motion mode (60+ FPS) and view the frames.
- 💻 Connect your laptop to another PC through USB-C/Thunderbolt and extract the memory dump from the folder
C:\Windows\Minidump. - 🔧 Boot from LiveCD (For example, Hiren’s BootCD) and analyze the dumps with the program BlueScreenView.
⚠️ Attention: If the laptop reboots in a loop of BSOD → Windows logo → BSOD, disable automatic reboot. To do this, when the Windows logo appears, hold downF8(orShift + F8for UEFI) and selectDisable automatic reboot on system failure.
Step-by-step instructions: what to do if the laptop does not turn on and shows BSOD
The algorithm of actions depends on whether the laptop can be loaded into at least safe mode. Let's start with the simplest steps:
Disconnect all external devices (flash drives, hard drives, printers)
Try booting into safe mode (hold F8 or Shift+F8)
Check the power cable and battery (for laptops)
Reset BIOS to factory settings (remove CMOS battery for 10 minutes)-->
Step 1: Boot into Safe Mode
If the laptop manages to show the Windows logo at least once before the BSOD, try entering safe mode:
- When the Windows logo appears, hold
Shiftand pressF8(for UEFI may be requiredShift + F8when turned on). - Select
Safe Mode with Networking. - If the download was successful, remove the latest driver updates via
Device Manager.
Step 2: System Restore
In Safe Mode or via Windows installation flash drive run recovery:
1. Нажмите Win + R → введите rstrui.exe → Enter.2. Выберите точку восстановления за 1–2 дня до появления BSOD.
3. Подтвердите откат системы.
Step 3: Check disk and system files
Open a command prompt as administrator and run:
chkdsk C: /f /rsfc /scannow
dism /online /cleanup-image /restorehealth
If chkdsk finds errors but cannot correct them - this is a sign physical damage to HDD/SSD.
If the laptop does not boot even in safe mode, create a bootable USB flash drive with Windows 10/11 and from the installation menu select System Restore → Command Prompt. From there you can run the same commands sfc And dism.
Step 4: Diagnose Hardware Faults
If software methods do not help, check:
- 🖥️ RAM: Remove the bars RAM one at a time and check the download. Use MemTest86 for deep dough.
- 💾 Hard drive/SSD: Connect to another PC and check SMART status program CrystalDiskInfo. Critical parameters:
Reallocated Sectors Count,Pending Sectors. - 🔌 Power supply: If the laptop shuts down 5-10 seconds after BSOD, it may not have enough power (especially for gaming models with RTX 30/40 series).
⚠️ Attention: If, when turned on, the laptop emits squeaks or reboots cyclically without displaying an image, the problem is most likely in motherboard or processor. In this case, independent repair is not recommended - contact service.
Advanced diagnostics: analyze memory dumps and Windows logs
Memory dumps (.dmp files) contain detailed information about the failure. To analyze them:
- Download the utility BlueScreenView (free, portable version).
- Run it as administrator - the program will automatically scan the folder
C:\Windows\Minidump. - Pay attention to the columns:
- Bug Check String — name of the error.
- Caused By Driver - problematic driver (for example,
nvlddmkm.sysfor NVIDIA).
Example of dump decryption:
Example of BlueScreenView dump analysis
Bug Check String: IRQL_NOT_LESS_OR_EQUAL
Caused By Driver: netio.sys
Caused By Address: netio.sys+1a3f0
Description: The crash is caused by the Windows network stack driver. Possible reasons:
- Incompatible VPN client (for example, NordVPN or OpenVPN).
- Damage to network settings after Windows update.
- Conflict with antivirus (Kaspersky, Avast).
Solution: Roll back the network card driver or remove the problematic software.
It's also useful to check Windows logs:
- Open
Event Viewer(eventvwr.msc). - Go to
Windows Logs → System. - Filter events by level
CriticalorErrorover the last 24 hours.

- 🔴
Disk- problems with the drive. - 🔴
ACPI- power management failures (often on laptops) Dell or HP). - 🔴
volmgr- bootloader errors.
Specific problems for different laptop models
Some brands have typical "diseases", causing BSOD when turned on. Here are the most common:
| Brand/Model | Typical problem | Solution |
|---|---|---|
| Lenovo Legion, Ideapad Gaming | BSOD WHEA_UNCORRECTABLE_ERROR due to overheating GPU or CPU. |
Cleaning dust, replacing thermal paste, turning off Turbo Boost in BIOS. |
| HP Pavilion, Omen | Cyclic BSOD after BIOS update. | Rolling back the BIOS to the previous version via HP Support Assistant. |
| ASUS ROG, TUF | Crash DRIVER_POWER_STATE_FAILURE when operating on battery power. |
Driver update ACPI and resetting the power plan. |
| Acer Swift, Spin | BSOD CRITICAL_PROCESS_DIED after hibernation. |
Disabling hibernation via powercfg /h off. |
For laptops Dell XPS And Latitude characteristic error SYSTEM_THREAD_EXCEPTION_NOT_HANDLED due to driver conflict Intel Management Engine. Solution:
- Download the latest driver from the website Dell.
- Uninstall the old version via
Device Manager → System Devices → Intel(R) Management Engine Interface. - Install the new driver and reboot.
If your laptop is a game series (For example, MSI GE, Alienware), check the temperature of the components first. BSOD on startup is often caused thermal throttling due to dried thermal paste or a faulty cooler.
When professional repairs are required: signs of serious problems
Not all BSOD problems can be resolved on your own. Contact the service center if:
- 🔥Laptop overheats (the case is hot, the cooler is running at maximum) and turns off 1-2 minutes after the BSOD.
- 💥 appears on the screen artifacts (stripes, dots) before or after BSOD - this is a sign of a malfunction video cards or motherboard.
- 🔌 Laptop doesn't turn on at all (no indication, does not respond to the power button) after several BSOD cycles.
- 💾 CrystalDiskInfo shows status
BadorCautionfor storage. - 🔧 Have you tried all methods from this article, but the BSOD is repeated with the same error code.
The cost of repair depends on the malfunction:
- 💿 Replacement HDD/SSD: from 1,500 to 5,000 ₽ (depending on the drive model).
- 🖥️ Replacement RAM: from 2,000 to 8,000 ₽ (for DDR4/DDR5).
- 🔥Repair motherboard (resoldering of chips, replacement of capacitors): from 5,000 to 20,000 ₽.
- 💻 Replacement video cards (for laptops with NVIDIA/AMD): from 10,000 to 30,000 ₽.
⚠️ Attention: If the laptop is under warranty, do not open it yourself - this will void the warranty. Contact an authorized brand service center (Lenovo, HP, ASUS etc.).
BSOD prevention: how to avoid repeated crashes
To minimize the risk of blue screens in the future, follow these guidelines:
- 🔄 Update your drivers regularly, but not through Windows Update, and from the official websites of manufacturers (NVIDIA, Intel, AMD).
- 💾 Check the health of your drive once every 3 months using CrystalDiskInfo or HDDScan.
- 🔋 Don't interrupt Windows updates This is a common cause of system file corruption.
- 🛡️ Use a reliable antivirus (For example, Kaspersky Internet Security or Bitdefender), but disable it while installing drivers.
- 🔥 Control the temperature: Clean the cooling system once every 6 months, use a cooling pad for gaming laptops.
For laptops with two video cards (integrated Intel + discrete NVIDIA/AMD) recommended:
- Disable automatic graphics switching in
NVIDIA/AMD Control Panel. - Update the drivers of both video cards to the latest versions.
- Set the main graphics adapter in BIOS
Discrete Graphics(if the laptop is used for gaming).
If you often work with virtual machines (VMware, VirtualBox), disable the function Hyper-V in Control Panel → Programs and Features → Turn Windows features on or off. Hypervisor conflict is a common cause of BSOD KMODE_EXCEPTION_NOT_HANDLED.
FAQ: Frequently asked questions about BSOD when turning on a laptop
My laptop shows BSOD with code 0x0000007B after replacing HDD with SSD. What to do?
This error is related to incompatibility of SATA modes. Go to BIOS (Del/F2 when turned on) and check the settings:
- Set mode
AHCI(notIDEorRAID). - If SSD NVMe, make sure your BIOS has support enabled
NVMe Boot. - Update your BIOS to the latest version.
If the problem persists, download the driver SATA controller for your laptop model and integrate it into the Windows installation flash drive using Dism++.
The laptop turns on, shows the Windows logo, then goes into BSOD and reboots in a loop. How to stop rebooting?
Disable automatic reboot:
- When the Windows logo appears, hold
Shiftand press repeatedlyF8(for UEFI may not work). - If that doesn’t work, create a bootable Windows USB flash drive, boot from it, click
Shift + F10to bring up the command line and run:
bcdedit /set {default} bootmenupolicy legacy
bcdedit /set {default} recoveryenabled No
After this, the laptop will no longer reboot automatically and you will be able to record the BSOD code.
BSOD only appears when running on battery power. When connected to the network everything is fine. What's the matter?
This is a common problem for laptops with worn out batteries or incorrect power settings. Check:
- Battery status
Command line → powercfg /batteryreport(look for the lineDesign CapacityvsFull Charge Capacity). If the difference is more than 30%, replace the battery. - Power Plan Settings: Go to
Control Panel → Power Options → Configure power plan → Change advanced power settingsand reset them to default values. - Driver ACPI: update it via
Device Manager → System Devices.
Is it possible to recover data from a laptop that won't turn on due to BSOD?
Yes, there are several ways:
- Connect the drive to another PC through USB SATA adapter or docking station for M.2.
- Use LiveCD (For example, Ubuntu Live or Hiren’s BootCD) to access files.
- Extract data via command line:
1. Загрузитесь с установочной флешки Windows.2. Нажмите
Shift + F10.3. Выполните:
notepad
Файл → Открыть → Перейдите вC:\Users\и скопируйте нужные файлы на флешку.
If the drive is physically damaged (for example, HDD makes a grinding noise), contact a data recovery laboratory.
After updating Windows 11, the laptop does not turn on and shows BSOD. How to roll back?
Use restore point or rollback to a previous version of Windows:
- Boot from the Windows 11 installation flash drive.
- Select
System Restore → Troubleshooting → Advanced Options. - Try:
Startup Recovery(if the problem is in the bootloader).System Restore(select point before update).Return to previous version(if the update was installed less than 10 days ago).
If rolling back doesn't help, you'll have to install Windows again with saving files (optional Update this computer in the recovery menu).
