Step 1: Boot into Safe Mode

Safe Mode loads only essential programs, helping you troubleshoot easily.

  • Restart your PC.

  • Press F8 (or Shift + F8) during startup or force shutdown 3 times to trigger recovery mode.

  • Choose Troubleshoot → Advanced Options → Startup Settings → Restart → Safe Mode.

Pro Tip: If your PC runs fine in Safe Mode, the problem is likely a driver or software issue.


Step 2: Use the System File Checker (SFC)

Windows has a built-in tool to repair missing or corrupted system files.

  • Open Command Prompt as Administrator.

  • Type:

    bash
    sfc /scannow

  • Press Enter and wait for the scan to complete. It will automatically fix any damaged files.


Step 3: Run the DISM Tool

If SFC alone doesn’t fix the issue, use DISM (Deployment Image Servicing and Management).

  • Open Command Prompt as Administrator.

  • Type the following commands one after another:

    swift
    DISM /Online /Cleanup-Image /CheckHealth

    DISM /Online /Cleanup-Image /ScanHealth

    DISM /Online /Cleanup-Image /RestoreHealth

  • Press Enter after each command.

Pro Tip: This tool checks deeper and restores critical Windows system health.


Step 4: Perform a System Restore

If your system was working fine a few days ago, restore it to a previous point.

  • Search for System Restore in the Start menu.

  • Choose Recommended Restore or pick a different restore point when your PC was stable.


Step 5: Reset or Reinstall Windows (as a Last Resort)

If nothing works, you might need to reset your PC:

  • Go to Settings → Update & Security → Recovery.

  • Under Reset this PC, click Get started.

  • Choose whether to keep your files or remove everything.
    (Backing up your data first is recommended!)
