⚠️ Why This Error Happens

The error can happen during boot, after login, or randomly while working. It often leads to restart loops or recovery mode. Common causes include:

• Corrupted system files (from power loss, failed updates, or malware)
• Incompatible or outdated drivers (especially for storage, antivirus, chipset)
• Failing SSD/HDD (bad sectors or controller issues)
• Interruptions during critical Windows updates
• Malware or rootkit infections
• Unstable overclocking or BIOS settings

🛠️ Step-by-Step Solutions

Here are 8 step-by-step solutions. Start from the top and work your way down.

✅ 1. Run System File Checker (SFC)

Goal: Detect and repair corrupted Windows system files.

Steps:

1. Boot into Windows Recovery Environment (WinRE):

   • If your PC won't boot, turn it on and off 2–3 times forcefully to trigger recovery.
   • Or boot from a Windows installation USB (created via Media Creation Tool)

2. Go to: Troubleshoot → Advanced Options → Command Prompt

3. In Command Prompt, type:

   sfc /scannow

4. Wait for the scan to complete (can take 10–15 mins). Follow any recommendations.

✅ 2. Run DISM to Restore System Health

Goal: Use Windows Update to restore broken system components.

Steps:

1. In the same Command Prompt (from recovery), enter:

   DISM /Online /Cleanup-Image /RestoreHealth

2. Let it finish (can take 10–20 mins). If it fails, try running it again.

✅ 3. Check Disk for Errors (CHKDSK)

Goal: Detect and fix disk issues like bad sectors or file system errors.
