Fix Driver Overran Stack Buffer Error on Windows 11? 7 Fixes That Actually Work

The Driver Overran Stack Buffer error on Windows 11 usually indicates a serious problem with system drivers or memory handling, where a faulty or outdated driver attempts to overwrite protected data in memory. To prevent potential system corruption or security risks, Windows immediately shuts down, with BSOD error DRIVER_OVERRAN_STACK_BUFFER. In most cases, this error occurs due to incompatible drivers, corrupted system files, or even certain third-party software. If you’ve recently updated Windows, installed new hardware, or noticed random crashes, you’re not alone. Many users encounter the Driver Overran Stack Buffer error after system changes or driver conflicts. Whatever the reason, here are 7 proven fixes to resolve the Blue Screen of Death error on Windows 11 and get your PC running smoothly again.

What causes the Driver Overran Stack Buffer Error?

Before jumping into fixes, it’s important to understand why the Driver Overran Stack Buffer error happens. This will help you identify the root cause and apply the right solution instead of guessing.

According to Microsoft, this BSOD occurs when a driver attempts to write more data to a protected memory area (the kernel stack) than it’s allowed to. Windows detects this as a potential security risk (similar to a buffer overflow attack) and immediately shuts down the system to prevent damage.

Here are the most common reasons behind this error:

• Corrupted or Outdated Drivers: Drivers act as a bridge between hardware and Windows. If a driver is outdated, incompatible, or corrupted, it may behave unpredictably and overwrite memory it shouldn’t—triggering the Driver Overran Stack Buffer error.
• Corrupted Windows System Files: Essential Windows system files can become corrupted due to improper shutdowns, malware infections, or failed updates. When these files don’t function correctly, they can interfere with driver operations and cause system crashes.
• Problematic Third-Party Software: Certain third-party applications—especially antivirus programs, system optimizers, or low-level utilities—can conflict with system drivers and memory processes, increasing the chances of this error.
• Overclocking or System Tweaks: If you’ve overclocked your CPU, GPU, or RAM, it can make your system unstable. Even minor instability in memory operations can lead to buffer overflow-type issues and trigger this BSOD.
• Hardware Conflicts or Failing Components: Defective RAM, failing SSD/HDD, or newly installed hardware that isn’t fully compatible with your system can cause memory-related issues. Since this error is closely tied to memory handling, hardware problems are a major trigger.

Quick Fix: Disconnect External Devices & Restart

External devices (USB drives, printers, adapters, external GPUs) install their own drivers. If one of them is corrupt or incompatible, it can trigger the Driver Overran Stack Buffer error during boot.

• Turn off your PC completely
• Unplug all external devices, excluding keyboard and mouse,
• Power ON the computer.

If the system stops crashing, reconnect each device one by one to find out the culprit.

Important: Boot into Safe Mode (If BSOD Happens Frequently)

Safe Mode loads only essential drivers, preventing problematic drivers or software from crashing your system. This gives you a stable environment to apply fixes. If Windows crashes before you can boot into the desktop, start the computer in Safe Mode and apply the solutions below.

How to boot into Safe Mode

1. Force shutdown your PC 2–3 times during boot
2. Windows will open the Recovery Environment
3. Go to: Troubleshoot → Advanced Options → Startup Settings
4. Click Restart
5. Press 4 (Safe Mode) or 5 (Safe Mode with Networking)

👉 Once in Safe Mode, follow the fixes below.

Fix 1: Update, Roll Back, or Reinstall Drivers (Most Important Fix)

Device drivers act as a communication bridge between your hardware and the Windows operating system. When these drivers become outdated, incompatible, or corrupted, they can send incorrect data to system memory or attempt unauthorized memory access, triggering the Driver Overran Stack Buffer error.

Updating or reinstalling drivers ensures proper communication between hardware and Windows, resolves compatibility issues, and prevents memory-related crashes.

Updating device drivers is crucial for maintaining system stability and compatibility.

Update drivers from Device Manager

• Press Windows + X → Device Manager
• Expand a category example Display adapters.
• Right-click your graphics card and choose Update driver.
• Click Search automatically for drivers and let Windows search.
• Repeat these steps for other important devices (such as Network adapters or Storage controllers).
• Restart your PC when you’re done.

Get the latest GPU drivers from the manufacturer (recommended)

For the Driver Overran Stack Buffer Error while gaming on Windows 11, the GPU driver is often to blame. Download the latest driver from:

• NVIDIA GeForce Experience / NVIDIA.com
• AMD Software: Adrenalin Edition
• Intel Arc / Intel Graphics

Install the latest Windows 11‑compatible driver, then restart.

Roll back a recently updated driver

If the error started right after a driver update, rolling back can help.

1. Open Device Manager.
2. Right‑click the suspected device (often GPU, network, or storage) and choose Properties.
3. Go to the Driver tab.
4. Click Roll Back Driver (if available) and follow the prompts.
5. Restart your PC.

If you can’t roll back, uninstall the driver and install a known stable version from the manufacturer’s website.

Fix 2: Repair Corrupted System Files (SFC + DISM)

Windows system files manage memory operations and driver interactions. If these files are corrupted, they can cause improper memory handling and trigger BSOD errors. Running SFC and DISM scans repairs these files and restores system stability.

• Type cmd in the Start menu search. Right‑click Command Prompt and select Run as administrator.
• Now type the command sfc /scannow and press the Enter key
• The utility scans for corrupt system files and attempts to repair them.

This will start the scanning process for corrupted and missing system files. If this System File Checker finds out incorrect files, overwrite the protected files. It will extract the correct system file from the system file backup (namely, dllcache) and replace the incorrect file.

This process may take some time, so be patient and avoid interrupting it.

Once done, you need to reboot your PC to take the changes into effect.

Note – In some cases, the SFC scan may not be able to repair all corrupted files. If that happens, you can try running the DISM (Deployment Image Servicing and Management) command to repair the Windows system image.

DISM /Online /Cleanup-Image /RestoreHealth

Once done, restart your computer. Try using your PC normally and check if the Driver Overran Stack Buffer BSoD appears again.

Fix 3: Install Latest Windows Updates

Keeping Windows updated ensures you have the latest security and compatibility fixes. Updates address known bugs, security vulnerabilities, and issues with hardware compatibility that could trigger Blue Screen errors like DRIVER OVERRAN STACK BUFFER.

Updating Windows to the latest version is always recommended as this makes the PC more stable

• Press Windows key + I to open the Windows settings app,
• Go to Windows update, and hit the check for updates button,
• If new updates are pending there, allow them to download and install on your computer.
• Restart your computer to apply changes.

After updating, use the system for a while to see if the blue screen returns.

Fix 4: Check RAM Using Windows Memory Diagnostic

Your hardware can often cause these types of errors. If you recently installed any new hardware, we advise you to remove or replace it and check whether that resolves the error. If your hardware is incompatible with your motherboard, your system will crash and you’ll get a BSOD.

Also, faulty Memory Modules can sometimes cause Blue Screen Errors. The Windows Memory Diagnostic Tool checks your system memory for errors, helps you identify and fix faulty RAM.

• Press the Windows key + R, type mdsched.exe, and hit the Enter key to open the Windows Memory Diagnostic Tool.

• Here you will see two options to run the Tool, save your work, and click on the first option, Restart now and check for problems.
• This will restart Windows and check for memory Module Errors.
• Wait until the process completes 100%, then restart Windows. You can find the Memory Diagnostic Test Results from here.

If the test reports memory errors:

• Power off the PC and reseat the RAM sticks (remove and reinsert them).
• Test one stick at a time, if you have multiple.
• Replace the faulty RAM module if the errors persist.

Advanced users: For deeper testing, use MemTest86 (USB boot) and run several passes overnight.

Fix 5: Diagnose and Repair Hard Drive Issues (Bootrec + CHKDSK)

Bad sectors, file system errors, or problems with the Master Boot Record (MBR) can also cause crashing and BSODs. Checking your hard drive and repairing errors can help address physical or data problems.

• If you can’t boot normally, enter Safe Mode or Windows Recovery Environment (WinRE).
• Open Command Prompt as administrator.
• Run bootrec.exe /rebuildbcd, bootrec.exe /fixmbr, and bootrec.exe /fixboot sequentially.
• Type chkdsk /r c: and follow prompts to schedule a disk check.
• Restart your PC to perform the scan.

If your drive shows heavy bad sectors, consider replacing the HDD/SSD.

Fix 6: Disable Overclocking (Improve Stability)

Overclocking increases hardware performance but reduces stability. It can cause memory timing issues, leading to buffer overflow errors. Resetting to default settings ensures stable operation.

Reset BIOS/UEFI to default settings

1. Shut down your PC completely.
2. Turn it back on and repeatedly press the key to enter BIOS/UEFI (usually Del, F2, F10, or Esc, depending on your motherboard).
3. In the BIOS/UEFI menu, look for an option such as:
   • Load Optimized Defaults
   • Load Setup Defaults
   • Load UEFI Defaults
4. Select it and confirm to reset everything to default.
5. Save changes and exit (often F10 to Save & Exit).

This will remove CPU, RAM, and some GPU overclock settings applied directly in BIOS.

Turn off software overclocking tools

If you use overclocking utilities in Windows (for example, MSI Afterburner, ASUS GPU Tweak, Intel XTU, AMD Ryzen Master):

1. Open each overclocking app you use.
2. Click Reset, Default, or Apply default/stock settings for that hardware.
3. Disable any options that apply an overclock on startup.
4. Restart your PC.

Fix 7: Use System Restore (Rollback Recent Changes)

If the Driver Overran Stack Buffer Error started after installing a driver, update, or software, System Restore can revert your system to a stable state before the issue occurred.

• In the Start menu, search for Create a restore point and open it.
• Under the System Protection tab, click System Restore.
• Click Next and choose a restore point dated before the crashes started.
• Click Next > Finish to start the restore process.
• Your PC will restart and restore system files and settings.

If none of the above fixes work and the system still hits the Driver Overran Stack Buffer Error, resetting Windows might be the fastest path to a stable system.

1. Go to Settings > System > Recovery.
2. Under Reset this PC, click Reset PC.
3. Choose Keep my files (apps and settings will be removed) or Remove everything.
4. Follow the on‑screen steps to reinstall Windows.

After the reset, install the latest drivers and apps gradually, checking for errors as you go.
