Blue Screen and Restart Windows 11: Fixes That Work
If your Windows 11 PC shows a blue screen and immediately restarts, the stop code on that screen tells you what went wrong, and most causes fall into a few fixable categories: driver faults, failing hardware, or corrupted system files. This article walks you through the exact steps to diagnose the error, stop the automatic restart so you can read the code, and apply the fixes that resolve the majority of BSOD cases.
Why Windows 11 Restarts After a Blue Screen
By default, Windows 11 is set to automatically restart when it hits a critical system error. This is meant to prevent data loss and get you back to work quickly, but it also means the blue screen—with its all-important stop code—flashes for only a second or two before the PC reboots. The restart behavior itself is not the problem; it is a safety feature. The underlying cause is the stop code, which is a hexadecimal value like CRITICAL_PROCESS_DIED or IRQL_NOT_LESS_OR_EQUAL. Each code points to a different subsystem: memory, storage, drivers, or power.
How to Stop the Automatic Restart and Read the Error
Before you can fix anything, you need to see the full error. Windows 11 lets you disable the auto-restart from the Advanced Startup settings, but if the PC is already in a restart loop, you may need to interrupt the boot process three times: turn the PC on, and as soon as the Windows logo appears, hold the power button until it shuts off. Repeat this twice. On the third boot, Windows should enter the Recovery Environment.
- In the Recovery Environment, click Advanced options.
- Click Startup Settings.
- Click Restart.
- After the restart, press F1 or the number key for Disable automatic restart on system failure.
Now when the blue screen appears, it will stay on screen until you manually restart. Write down the stop code and the driver name listed at the bottom (if any). That driver name is often the direct culprit.
Common Stop Codes and What They Mean
Different stop codes require different fixes. Here are the most frequent ones on Windows 11 and their usual causes:
- MEMORY_MANAGEMENT – Faulty RAM or corrupted page file. Run Windows Memory Diagnostic.
- IRQL_NOT_LESS_OR_EQUAL – A driver accessed memory at an incorrect interrupt level. Often a network or graphics driver.
- CRITICAL_PROCESS_DIED – A core Windows process stopped unexpectedly. Often fixed by System File Checker or a recent driver rollback.
- SYSTEM_SERVICE_EXCEPTION – A driver or service threw an unhandled exception. Check the driver name in the error.
- PAGE_FAULT_IN_NONPAGED_AREA – The system tried to access memory that does not exist. Usually RAM or storage driver issues.
- VIDEO_TDR_FAILURE – The graphics card stopped responding. Update or roll back the GPU driver.
If you see WHEA_UNCORRECTABLE_ERROR, that points to hardware failure, most commonly CPU or motherboard. That one is less likely to be fixed by software alone.
Step-by-Step Fixes to Try in Order
Start with the least invasive fixes and move to more involved ones. Do not skip the first two—they resolve a surprisingly large share of BSODs.
1. Run Windows Update and Driver Updates
Open Settings > Windows Update and click Check for updates. Install all pending updates, including optional driver updates under Advanced options > Optional updates. Many BSODs are caused by known bugs that Microsoft or hardware vendors have already patched.
2. Use System File Checker and DISM
Corrupted system files can cause random blue screens. Open Command Prompt as administrator and run:
sfc /scannow– scans and repairs protected system files.DISM /Online /Cleanup-Image /RestoreHealth– repairs the system image that SFC relies on.
Reboot after both complete. If SFC found and fixed files, that may be the end of the problem.
3. Roll Back or Uninstall Recent Drivers
If the BSOD started after a driver update, go to Device Manager, find the device, right-click it, and select Properties > Driver > Roll Back Driver. If rollback is unavailable, choose Uninstall device and then reboot—Windows will reinstall the generic driver.
4. Check for Overheating and Power Issues
Overheating CPUs and GPUs cause unstable operation and blue screens. Download a temperature monitoring tool and check idle and load temperatures. If the CPU exceeds 90°C under load, clean dust from heatsinks and fans, and ensure the thermal paste is still effective. Also disable any aggressive overclocking in BIOS/UEFI, including XMP/EXPO memory profiles, to see if the BSOD stops.
5. Test Your RAM
Memory errors are a leading cause of BSODs. Press Windows key + R, type mdsched.exe, and choose Restart now and check for problems. The test takes 20–30 minutes. If it finds errors, replace the faulty RAM stick. If you have multiple sticks, test them one at a time to isolate the bad one.
6. Check Disk for Errors
Open Command Prompt as administrator and run chkdsk C: /f /r. You will be prompted to schedule it for the next restart. This scans for bad sectors and file system corruption on your system drive. If the drive is failing, you will see numerous bad sectors, and you should back up your data immediately.
7. Perform a Clean Boot
A clean boot starts Windows with only the essential drivers and services. If the blue screen does not occur in a clean boot, a third-party service or startup program is the cause. Use msconfig to disable all non-Microsoft services and startup items, then re-enable them one by one to find the offender.
When to Reset or Reinstall Windows 11
If you have tried all the above and the BSOD persists, the problem may be a deeply corrupted Windows installation. The Reset this PC feature in Settings > System > Recovery lets you reinstall Windows while keeping your personal files (choose Keep my files). This is a less drastic step than a full clean install and often clears system-level corruption that SFC cannot fix. If the blue screen still appears after a reset, the issue is almost certainly hardware—RAM, storage drive, motherboard, or power supply—and you should consider replacing those components.
Common Mistakes and Misconceptions
One widespread misconception is that a blue screen always means imminent hardware failure. In reality, most BSODs on Windows 11 are driver-related and fixable with a simple update or rollback. Another mistake is ignoring the stop code and immediately reinstalling Windows. That is the slowest path. The stop code is your diagnostic map; without it, you are guessing.
Another frequent error is disabling the automatic restart permanently. That setting is useful for troubleshooting but should be re-enabled once you have the code, because leaving it off means your PC will sit on a blue screen indefinitely after a crash, which can lead to data loss if you are not present.
Finally, do not assume a single fix works for all codes. A VIDEO_TDR_FAILURE is rarely fixed by running SFC; it needs a GPU driver change. Matching the fix to the code is the fastest route.
Frequently Asked Questions
How do I find the blue screen error code if my PC restarts too fast?
Disable automatic restart as described above, or check the Event Viewer. Open Event Viewer > Windows Logs > System and look for events with source BugCheck or Kernel-Power. The BugCheck event will contain the stop code and often the driver that caused it.
Can a blue screen be caused by a virus?
Yes, though it is less common than driver issues. Rootkits or malware that hook into kernel functions can cause instability. Run a full scan with Windows Defender or a reputable third-party scanner. If the BSOD appears during boot, use Windows Defender Offline from the Recovery Environment.
Is it safe to keep using my PC after a blue screen?
If the blue screen happens once and does not recur, it is generally safe to continue, but you should still check for driver updates and run SFC. If it happens repeatedly, continuing to use the PC risks data corruption, especially if the cause is a failing hard drive or RAM. Back up important files before doing more troubleshooting.
Will a system restore fix the blue screen?
It can, if the BSOD started after a recent change like a driver install or a Windows update. System Restore reverts system files and registry settings to an earlier point without affecting your personal files. Try it before resetting Windows, but note that it will not fix hardware-related BSODs.
How do I check if my RAM is causing the blue screen?
Run the Windows Memory Diagnostic tool (mdsched.exe). If it reports errors, your RAM is faulty. You can also use third-party tools like MemTest86, but the built-in tool is sufficient for most cases. Replace the faulty stick and re-test.
What does the blue screen stop code 0x0000007B mean?
That is INACCESSIBLE_BOOT_DEVICE. It means Windows cannot access the drive that contains the system files. This is often caused by a storage driver issue, a loose SATA cable, or a failing hard drive. Check BIOS/UEFI to ensure the correct drive is set as the boot device, and run chkdsk from the Recovery Environment.
