How to Resolve It
How to Resolve It
Work through the steps below in order. If your laptop is crashing repeatedly, start from Step 1. These methods are tried-and-true for resolving BSOD issues.
Step 1: Boot into Safe Mode
Step 1: Boot into Safe Mode
If the laptop keeps crashing before Windows loads:
Power on the laptop.
Force shutdown as soon as the Windows logo appears.
Repeat this 3 times — Windows will enter Automatic Repair mode.
Navigate to: Advanced options → Startup Settings → Restart.
Press 4 to boot into Safe Mode.
Safe Mode loads Windows with minimal drivers, letting you troubleshoot without crashes.
Step 2: Run System File Checker
Step 2: Run System File Checker
Open Command Prompt as Administrator and run:
sfc /scannow
This scans for and repairs corrupted system files.
Wait for the scan to complete (may take 10–20 minutes).
Restart after it finishes.
Step 3: Run DISM to Repair Windows Image
Step 3: Run DISM to Repair Windows Image
Still in an elevated Command Prompt, run:
DISM /Online /Cleanup-Image /RestoreHealth
This repairs deeper OS-level corruption that sfc may miss.
Requires an internet connection to download repair files from Windows Update.
Restart when complete.
Step 4: Check Your Disk for Errors
Step 4: Check Your Disk for Errors
Run the following in Command Prompt (Admin):
chkdsk C: /f /r
/f — fixes filesystem errors
/r — locates bad sectors and recovers readable data
When prompted, press Y to schedule the scan on next reboot, then restart. This can take 30–60 minutes depending on disk size and condition.
Step 5: Update or Reinstall Drivers
Step 5: Update or Reinstall Drivers
Focus on these driver categories first:
Storage drivers — Intel RST / AHCI / NVMe
Graphics drivers — NVIDIA / AMD / Intel
Network drivers — Wi-Fi / LAN adapters
How to update:
Open Device Manager (Win + X → Device Manager).
Right-click the device → Update driver.
Alternatively, download the latest drivers directly from the manufacturer's website.
Step 6: Uninstall Recent Updates or Software
Step 6: Uninstall Recent Updates or Software
If the BSOD started after a Windows Update, driver install, or new application:
Go to Settings → Windows Update → Update history.
Click Uninstall updates.
Remove the most recent update or any suspicious software.
Step 7: Scan for Malware
Step 7: Scan for Malware
Run a full malware scan using one of:
Windows Defender Offline Scan Settings → Windows Security → Virus & threat protection → Scan options → Microsoft Defender Offline scan
Malwarebytes (free version) Download from the official Malwarebytes website
Step 8: Check Hardware
Step 8: Check Hardware
If the laptop is old, has been dropped, or the issue persists after all software fixes:
Check RAM:
Win + S → "Windows Memory Diagnostic" → Restart now and check for problems
Check SSD/HDD health:
Download and run CrystalDiskInfo (free)
Look for a Caution or Bad health status
Pay attention to Reallocated Sectors and Pending Sectors counts
A failing drive is one of the most common hardware causes of this stop code.
If This Happened Only Once
If This Happened Only Once
Sometimes Windows crashes once due to a temporary glitch — a power fluctuation, a brief driver conflict, or a one-off process failure. If the crash does not repeat, it is generally harmless.
Monitor the system for a few days. If it stays stable, no further action is needed.
If It Keeps Happening
If It Keeps Happening
Provide the following details to help pinpoint the exact cause:
When did this start?
Did you install anything recently (software, drivers, updates)?
Is the laptop slow or making clicking/grinding sounds?
Does it restart repeatedly or loop back to the blue screen?
With this information, the root cause can usually be identified and a targeted fix applied.
