DRIVER_OVERRAN_STACK_BUFFER Windows Error: Why it occurs, How to fix it

The DRIVER_OVERRAN_STACK_BUFFER issue is a Blue Screen of Death (BSOD) error on Windows 10.

This error typically indicates that a driver has caused a buffer overflow by overrunning the stack, which is a common type of memory corruption issue.
If you noticed that this issue started occurring after an update to the CrowdStrike Falcon Sensor, but the computer is not directly related to the Falcon software or CrowdStrike, it could still be due to various reasons, including conflicts with other software or drivers.

Here are some steps to troubleshoot and resolve the DRIVER_OVERRAN_STACK_BUFFER error:

1. Update All Drivers
   Ensure all your drivers are up to date. You can use Device Manager to check for updates or visit the manufacturers' websites for the latest drivers.

2. Uninstall Recent Updates
   If the issue started after a recent update, try uninstalling the update to see if it resolves the issue.

Go to Settings > Update & Security > Windows Update > View update history > Uninstall updates.

1. Check for Software Conflicts Since the problem started after a CrowdStrike update, consider uninstalling or disabling the Falcon Sensor temporarily to see if the issue persists.

Go to Control Panel > Programs > Programs and Features and uninstall the software.

1. Run a System File Checker (SFC) Scan Corrupted system files can cause BSOD errors. Running an SFC scan can help identify and fix these files.

Open Command Prompt as Administrator.
Type sfc /scannow and press Enter.
Wait for the process to complete and follow any on-screen instructions.

1. Run the Windows Memory Diagnostic Tool Memory issues can also cause BSOD errors. Run the Windows Memory Diagnostic Tool to check for memory problems.

Press Windows + R, type mdsched.exe, and press Enter.
Choose to restart now and check for problems.

1. Check for Malware
   Malware infections can cause system instability. Run a full system scan using Windows Defender or any other reputable antivirus software.

2. Check Event Viewer
   The Event Viewer can provide more details about the cause of the BSOD.

Press Windows + X and select Event Viewer.
Look for critical errors under Windows Logs > System.

1. Perform a Clean Boot A clean boot can help you determine if background programs are interfering with your system.

Press Windows + R, type msconfig, and press Enter.
In the Services tab, check Hide all Microsoft services and click Disable all.
In the Startup tab, click Open Task Manager and disable all startup items.
Restart your computer.

1. Reset or Reinstall Windows 10 If none of the above steps work, you might need to reset or perform a clean installation of Windows 10. Ensure you back up your data before doing this.

If the issue persists after trying all these steps, it may be worth consulting with a professional technician to diagnose and resolve the issue more thoroughly.
