Solution Steps
- 1 Press Windows key + X and select 'Device Manager' from the menu. This opens a list of all hardware components. Look for devices with a yellow exclamation mark — these indicate driver problems.
- 2 Right-click on any problematic device (e.g., network adapter, graphics card) and select 'Update driver'. Choose 'Search automatically for drivers'. This lets Windows find and install the correct driver, which often fixes data handling issues.
- 3 If no update is found, visit the manufacturer's website and download the latest driver manually. Install it by running the downloaded file and following the on-screen instructions. Outdated drivers can cause buffer size mismatches.
- 4 Press Windows key + R, type 'cmd', and press Ctrl+Shift+Enter to open Command Prompt as administrator. Run 'sfc /scannow' to check for corrupted system files that might cause the error.
- 5 Restart your computer to apply all changes. After reboot, test the application that triggered the error.
