Windows 11 BSOD Error Code Decoder

Frequently Asked Questions — Windows 11 BSOD

What is a BSOD (Blue Screen of Death) in Windows 11?

A Blue Screen of Death (BSOD) is a critical system error screen that Windows 11 displays when it encounters a problem it cannot safely recover from. It stops all processes to prevent damage and shows a stop code — a hexadecimal number like 0x00000050 — that identifies the type of error. Common causes include faulty drivers, bad RAM, failing hard drives, and corrupted system files.

How do I find the BSOD stop code on Windows 11?

Windows 11 displays the stop code directly on the blue screen under the sad face icon. Look for a line that reads Stop code: followed by the error name. If the screen disappears too fast, open Event Viewer (press Win + R, type eventvwr), go to Windows Logs then System, and look for Critical or Error entries around the time of the crash. You can also check the minidump file located at C:\Windows\Minidump.

What are the most common causes of a BSOD in Windows 11?

The most common causes of BSODs in Windows 11 are outdated or corrupt device drivers (especially GPU, network, or storage drivers), defective or failing RAM, a failing hard drive or SSD with bad sectors, corrupted Windows system files, malware or rootkit infections, an overheating CPU or GPU, incompatible or recently installed software, and failed or incomplete Windows Updates.

How do I fix a BSOD on Windows 11?

Start by noting the stop code shown on the blue screen and searching it in the decoder above to get a specific fix. For general troubleshooting, boot into Safe Mode if the PC keeps crashing, update all device drivers via Device Manager, run sfc /scannow in an elevated Command Prompt, then run DISM /Online /Cleanup-Image /RestoreHealth. Also test your RAM using Windows Memory Diagnostic (mdsched.exe) and check your drive with chkdsk C: /f /r.

What does PAGE_FAULT_IN_NONPAGED_AREA (0x00000050) mean?

This stop code means Windows tried to access a memory address that does not exist or is not available. It is most commonly caused by defective RAM, a corrupt or outdated driver, or antivirus software interfering with system memory. To fix it, run Windows Memory Diagnostic to test your RAM, update or roll back recently installed drivers, temporarily disable your antivirus, and run sfc /scannow in an elevated Command Prompt.

What is WHEA_UNCORRECTABLE_ERROR (0x00000124)?

WHEA stands for Windows Hardware Error Architecture. This stop code means your hardware — most often the CPU, RAM, or motherboard — reported an error that Windows could not correct. Overclocking is the number one cause on gaming and enthusiast PCs. To fix it, disable all CPU, RAM, and GPU overclocking in BIOS, reset BIOS to default settings, test your RAM with MemTest86, and update your BIOS firmware to the latest version.

How do I fix VIDEO_TDR_FAILURE (0x00000116) on Windows 11?

This stop code means your graphics card stopped responding and Windows could not reset it. To fix it, use Display Driver Uninstaller (DDU) in Safe Mode to completely remove your current GPU drivers, then download and install the latest drivers directly from Nvidia.com or AMD.com. Also check your GPU temperature using GPU-Z or MSI Afterburner — it should stay under 85°C. If your GPU is overclocked, reset it to stock speeds and ensure your power supply provides enough wattage.

What is CRITICAL_PROCESS_DIED (0x000000EF)?

This stop code means a core Windows system process — such as smss.exe, csrss.exe, or wininit.exe — stopped running unexpectedly. Windows requires these processes to always be active, so it crashes immediately when one dies. Common causes are corrupted system files, malware, or a failed Windows Update. To fix it, run a full malware scan with Windows Defender, then run sfc /scannow followed by DISM /Online /Cleanup-Image /RestoreHealth. If the issue continues, use System Restore to revert to a point before the crashes started.

Can a BSOD permanently damage my computer?

A BSOD itself does not damage your computer — it is a protective mechanism designed to stop Windows before damage occurs. However, the underlying problem causing the BSOD, such as a failing hard drive, overheating components, or faulty RAM, can cause permanent damage if left unfixed. Repeated BSODs from a failing drive can also lead to data loss, so it is important to identify and fix the root cause as soon as possible.

How do I prevent BSODs on Windows 11?

To prevent BSODs on Windows 11, keep Windows and all drivers up to date, avoid overclocking unless you know how to test for stability, monitor CPU and GPU temperatures and ensure adequate cooling, run periodic hard drive health checks with CrystalDiskInfo, test your RAM with Windows Memory Diagnostic every few months, use a reputable antivirus and avoid installing unknown software, never force-shutdown your PC during Windows Updates, and consider using a UPS to protect against sudden power cuts.
