How to Fix Buffer Overrun Errors


A buffer overrun, also known as buffer overflow, occurs when a program overruns the buffer limits and starts to overwrite adjacent memory, resulting in data loss and slow performance. You can troubleshoot buffer overruns by a variety of methods. You may update your Windows operating system files. You may also enable Data Execution Prevention (DEP), which is a key buffer overrun defense feature. If your buffer overrun originates from your Internet Explorer web browser, which is a common problem, you may want to increase its security levels.

Perform a Windows Update

  • Click the "Start" menu and select "All Programs."

  • Locate the menu command "Windows Update." Click to launch the program.

  • Click the link "Check for updates" in the left pane. Let Windows install all the required updates.

  • Reboot your computer once the update installation is complete.

Increase Security Level in Internet Explorer

Enable Data Execution Prevention

  • Click the "Start" menu and select "Control Panel."

  • Click "System and Maintenance." Click "System."

  • Click "Advanced System Settings." Type the administrator password if prompted.

  • Click "Settings" listed under "Performance." Click the tab labeled "Data Execution Prevention."

  • Click "Turn on DEP for all programs and services except those I select."
