Solution Steps
- 1 Start by running the Windows Memory Diagnostic to check for RAM issues. Press Windows key + R, type 'mdsched.exe', and press Enter. Choose 'Restart now and check for problems'. This will test your RAM for errors—faulty memory is a common cause of heap corruption.
- 2 If memory is fine, update your drivers, especially the graphics driver. Press Windows key + X and select 'Device Manager'. Expand 'Display adapters', right-click your GPU, and select 'Update driver'. Choose 'Search automatically for drivers'. Outdated or corrupted drivers can corrupt the heap.
- 3 Run the System File Checker to repair corrupted system files. Press Windows key + R, type 'sfc /scannow', and press Enter. This scans and repairs protected system files that might be causing the corruption.
- 4 If SFC doesn't help, run DISM to repair the system image. Open Command Prompt as administrator (Windows key + X → 'Terminal (Admin)') and type 'DISM /Online /Cleanup-Image /RestoreHealth'. This fixes the underlying system image that SFC relies on.
- 5 Check for Windows updates: Press Windows key + I, go to 'Windows Update', and click 'Check for updates'. Install any pending updates, as they often include driver fixes and stability improvements.
