Solution Steps
- 1 Press Windows key + R, type 'mdsched.exe', and press Enter. Choose 'Restart now and check for problems'. This runs Windows Memory Diagnostic to test your RAM for errors. Corrupted memory can cause stack corruption. The test will take about 20 minutes and your PC will restart.
- 2 After the memory test, update your drivers. Press Windows key + X, select 'Device Manager'. Right-click each device and select 'Update driver' → 'Search automatically'. Pay special attention to chipset and graphics drivers.
- 3 Run System File Checker: Press Windows key + X, select 'Terminal (Admin)', type 'sfc /scannow', and press Enter. This repairs system files that might be causing the issue.
- 4 If the error occurs with a specific program, try reinstalling it. Uninstall from Settings → Apps, then download the latest version.
- 5 Check for overheating: Use a temperature monitoring tool like HWMonitor. If your CPU/GPU is running above 90°C, clean your fans and improve ventilation.
