Blue screen of death (BSOD) is one of the most frightening errors for users Windows. It appears suddenly, interrupts work and is often accompanied by a cryptic error code like CRITICAL_PROCESS_DIED or IRQL_NOT_LESS_OR_EQUAL. In 90% of cases, the problem can be solved without contacting a service center - the main thing is to act systematically.
In this article we will look at all possible reasons blue screen on laptops Lenovo, HP, Asus, Acer and other brands, and will also give step by step instructions for diagnosing and troubleshooting. We will pay special attention to cases when the laptop gets stuck on BSOD on boot or the screen appears after updating the drivers.
1. What is a blue screen of death (BSOD) and why does it appear?
BSOD (Blue Screen of Death) is an emergency stop screen that Windows Displays when there is a critical error in the system kernel. Unlike regular crashes, it indicates problems that the operating system cannot ignore: corrupted system files, driver conflicts, or hardware failures.
Key signs of BSOD:
- 🔵 The screen is completely blue with white text (in Windows 11 — black background with QR code)
- 🛑 An error code appears (for example,
KMODE_EXCEPTION_NOT_HANDLED) - 🔄 Automatic reboot after a few seconds (if the option is enabled
Automatic reboot) - 📁Creating a memory dump (
.dmpfile) in the folderC:\Windows\Minidump
The most common reasons:
- 🖥️ Driver problems (especially video cards, chipset, Wi-Fi)
- 💽 Damage to system files after updates or viruses
- 🔌 Random access memory (RAM) problems or hard drive
- 🔥 CPU/video card overheating due to dust or dried thermal paste
- ⚡ Software conflicts (antiviruses, overclocking utilities)
- First time
- Once a week
- Daily
- Only after updates
2. First steps: what to do immediately after a blue screen appears
If laptop rebooted after BSOD and now working fine, follow these steps immediately:
Check the error code (take a photo of the screen or look in the event log)
Disconnect all peripheral devices (printers, external drives, USB hubs)
Run a disk check with the command chkdsk /f /r in CMD as administrator
Update your video card drivers via Device Manager
Create a system restore point (Settings → Update & Security → Recovery)
-->
If laptop stuck on blue screen and won't load any further:
- Force shutdown the laptop by holding down the power button for 10 seconds
- Turn it on and press immediately
F8(orShift + F8for Windows 10/11) to get into menu of additional boot options - Select
Troubleshooting → Advanced Options → Boot Options → Restart - After restart, press
4orF4for safe mode
⚠️ Attention: If the laptop emits beeping sounds when turned on or appear on the screen artifacts (stripes, flickering) is a sign hardware failure video card or motherboard. In this case, further diagnostics using software methods is pointless.
3. How to decipher the BSOD error code
Every blue screen contains unique stop code, which helps determine the cause. For example:
CRITICAL_PROCESS_DIED- a critical process was terminated suddenly (often due to corrupted system files)IRQL_NOT_LESS_OR_EQUAL- problem with drivers or RAMVIDEO_TDR_FAILURE— graphics driver failure (video card NVIDIA/AMD)SYSTEM_THREAD_EXCEPTION_NOT_HANDLED- error in the system kernel
Where to look for the error code if the screen disappears:
- Open
Control Panel → Administrative Tools → Event Viewer → Windows Logs → System - Look for events with a level
Errorand sourceBugCheck - Or use the utility BlueScreenView (you can download from the official website NirSoft)
| Error code | Probable Cause | Recommended Solution |
|---|---|---|
MEMORY_MANAGEMENT |
Random access memory (RAM) error | Check memory sticks with utility MemTest86 |
NTFS_FILE_SYSTEM |
Damage to the file system on the disk | Execute chkdsk /f /r in CMD |
DPC_WATCHDOG_VIOLATION |
Driver conflict or SSD problems | Update chipset drivers and disable AHCI in BIOS |
BAD_SYSTEM_CONFIG_INFO |
Damage to the registry or configuration files | Restore the system via a restore point |
If the error code contains a file name (for example, nvlddmkm.sys), then the problem is in this driver. For NVIDIA This is the video card driver for athwbx.sys - Wi-Fi driver from Qualcomm Atheros.
4. Check and restore system files
Damaged system files are one of the most common causes of BSOD. To restore them, use the built-in utilities Windows:
Method 1: SFC (System File Checker)
sfc /scannow
This command checks the integrity of all protected system files and restores corrupted versions from the cache. The process may take 15-30 minutes. If the utility finds errors but cannot fix them, move on to the next method.
Method 2: DISM (Deployment Image Servicing and Management)
DISM /Online /Cleanup-Image /RestoreHealth
This command restores a system image using files from Windows Update. If your Internet is disabled, connect to the network before performing. For Windows 10/11 you can also use an additional parameter:
DISM /Online /Cleanup-Image /RestoreHealth /Source:esd:D:\sources\install.esd:1 /LimitAccess
Where D: — drive letter with the installation ISO image Windows (if it is connected).
⚠️ Attention: If after executionDISMerror appears0x800f081f, this means the recovery components are damaged. In this case, it will only help clean installation of Windows with data storage (described in section 7).
5. Diagnose hardware problems
If software methods do not help, the cause of the BSOD may lie in gland. Let's check the key components:
1. Test of random access memory (RAM)
- 🔧 Use the built-in utility
mdsched.exe(type in searchMemory Checker) - 💿 Or boot from a flash drive MemTest86 (recommended for deep scanning)
- ⚠️ If errors are found - replace the memory stick (even if errors do not appear on all tests)
2. Checking the hard drive/SSD
- 📊 For HDD: use CrystalDiskInfo (check options
Reallocated SectorsAndPending Sectors) - 🚀 For SSD: please note
Total Host Writes(if the value is close to the drive resource, it is worn out) - 🔍 For a deep check:
chkdsk /f /ror VictoriaHDD in modeRemap
3. Temperature monitoring
- 🌡️ Install HWMonitor or Core Temp and check temperatures under load
- 🔥 Normal values:
- CPU: up to 85°C under load (for Intel 10th generation and newer - up to 100°C)
- Video card: up to 90°C (for NVIDIA RTX 30 series - up to 83°C)
- ❄️ If temperatures are above normal - clean your laptop from dust and replace the thermal paste
How to properly clean your laptop from dust
1. Turn off the laptop and remove the battery (if possible).
2. Use soft brush And compressed air cylinder (not a vacuum cleaner!).
3. Pay special attention radiator And fan - they often become clogged with dust.
4. To replace thermal paste, use Arctic MX-4 or Noctua NT-H1 (apply a thin layer).
5. After cleaning, check the temperatures in AIDA64 under load (stability test).
6. Driver conflicts: how to find and resolve
Incorrectly installed or outdated drivers - the reason 70% of all BSODs. Drivers especially often cause problems:
- 🎮 Video cards (NVIDIA GeForce, AMD Radeon, Intel Iris Xe)
- 📶 Network adapters (Wi-Fi and Ethernet)
- 🔊 Sound cards (Realtek, Conexant)
- 🖨️ Printers and scanners (especially HP And Canon)
How to update drivers correctly:
- Open
Device Manager(Win + X → Device Manager) - Look for a device with a yellow exclamation mark (this is a sign of a problem)
- Right click →
Update driver → Automatic search - If the automatic search did not help, download the driver from manufacturer's official website (do not use driver packs like DriverPack Solution!)
How to roll back a driver if an update caused a BSOD:
- Boot into safe mode (as described in section 2)
- Open
Device Managerand find the problematic device - Right click →
Properties → Driver → Roll Back - If the button is inactive, remove the driver completely and reboot
Never install drivers through Windows Update for video cards NVIDIA/AMD - they are often outdated. Always download them from official sites: nvidia.ru or amd.com.
7. System restore and clean installation of Windows
If all the previous methods did not help, there are two radical solutions left:
Option 1: System Restore
- 🔄Load into safe mode or with installation flash drive
- Open
Control Panel → Recovery → Run System Restore - Select a restore point 2-3 days before the BSOD appears
- 🚨 Attention: All programs installed after the point was created will be deleted!
Option 2: Clean installation of Windows and saving data
- Create an installation flash drive with Windows 10/11 through Media Creation Tool
- Boot from the flash drive (click
F12/Escwhen turning on to select boot device) - On the installation screen, select
Custom installation - Remove system partition only (usually
Disk 0 Partition 2or3), leave the data section untouched - Install Windows on the free space
- After installation, your files will remain in the folder
Windows.oldon the system disk
⚠️ Attention: If laptop HP or Lenovo with preinstalled Windows, before clean install save all drivers from the manufacturer's official website. After installing bare Windows, the keyboard, touchpad, or Wi-Fi may not work.
8. Prevention: how to avoid BSOD in the future
To prevent blue screens from appearing again, follow these recommendations:
- 🔄 Update Windows regularly (but not immediately after the release of major updates - wait 2-3 weeks)
- 🛡️ Use licensed antivirus (Kaspersky, ESET NOD32) and don't turn it off Windows Defender
- 💾 Launch once a month
chkdsk /fAndsfc /scannowfor prevention - 🔥 Monitor the temperature: clean your laptop from dust every 6 months
- ⚡ Do not use programs for acceleration (For example, MSI Afterburner) on laptops - this reduces the life of components
- 🔌 When connecting new devices (printers, external drives) install drivers first, then connect the device
Create emergency flash drive with Windows PE (For example, Sergei Strelec) - it will help restore the system, even if Windows does not boot. The flash drive should have the following utilities: Acronis True Image, MemTest86, CrystalDiskInfo And Dism++.
FAQ: Frequently asked questions about a blue screen on a laptop
🔹 The laptop shows a blue screen when turned on and immediately turns off. What to do?
This is a sign critical bootloader error or hardware failure. Try:
- Boot from the installation flash drive and select
Startup Recovery - Disable in BIOS
Secure Bootand turn onLegacy Mode(if used Windows 7) - If it doesn’t help, check the RAM (pull out one stick if there are several of them)
If laptop Asus or MSI with two video cards (Intel + NVIDIA), try disabling discrete graphics in the BIOS.
🔹 After updating Windows, a blue screen appeared. How to roll back?
Use restore point:
- Boot into safe mode (button
F8orShift + Reboot) - Open
Control Panel → Recovery → Run System Restore - Select a point before the update date
If there is no point, roll back the update manually:
- Go to
Settings → Update & security → View update history → Uninstall updates - Find the latest update (usually with code
KB50XXXXXX) and delete it
🔹 The blue screen appears only when launching games. What's the matter?
Most likely the problem is video card driver or overheating. Actions:
- Update your video card driver from the official website (NVIDIA/AMD)
- Install MSI Afterburner and check the GPU temperature under load (normal: up to 85°C)
- Lower the graphics settings in the game (especially
ShadowsAndAnisotropic filtering) - If the laptop is old (for example, Lenovo G580 or HP Pavilion g6), try replacing the thermal paste
For laptops with NVIDIA Optimus (two video cards) check that the game runs on discrete video card (right-click on the executable file → Run with GPU → NVIDIA High Performance CPU).
🔹 Is it possible to replace RAM yourself if MemTest shows errors?
Yes, replacing RAM is one of the simplest hardware procedures. Instructions:
- Buy compatible memory stick (check the supported type in the laptop documentation)
- Turn off the laptop, remove the battery and unscrew the RAM compartment cover (usually marked with a 🏠 icon)
- Carefully remove the old strip by bending the latches on the sides
- Insert the new strip at a 45° angle and press until it clicks.
For laptops Apple MacBook, Dell XPS or HP Spectre The memory is often soldered to the motherboard - in this case, replacement is possible only at a service center.
🔹 BSOD appears with code WHEA_UNCORRECTABLE_ERROR. What does this mean?
This error indicates hardware failure, most often:
- 💥 Processor problems (overheating, core damage)
- 💾 Motherboard failure (for example, swollen capacitors)
- ⚡ Unstable power supply (faulty power supply or battery)
Actions:
- Check the CPU temperature in HWMonitor (if above 90°C - cleaning + replacing thermal paste)
- Unplug the laptop and run it on battery power (or vice versa) - if the BSOD disappears, the problem is in the power supply
- Update the BIOS (but only if you are sure that the power supply is stable!)
If the error appears on the laptop MSI, Gigabyte or ASUS ROG with overclocking - reset BIOS settings to factory settings (Load Optimized Defaults).
