How to Fix Buffer Overrun Errors

Shares & Saves

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

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

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

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

  4. Reboot your computer once the update installation is complete.

Enable Data Execution Prevention

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

  2. Click "System and Maintenance." Click "System."
