Steps to Resolve Error 0x00000031

Step 1: Boot into Safe Mode

Safe Mode starts Windows with a minimal set of drivers and services. If the error is caused by a driver or service, Safe Mode might allow you to boot successfully.

1. Restart your computer.
2. As soon as your computer starts, press the F8 key repeatedly until the Advanced Boot Options menu appears.
3. Select "Safe Mode" and press Enter.

Step 2: Update or Roll Back Drivers

Outdated or incompatible drivers can cause this error. In Safe Mode, you can update or roll back drivers.

1. Press Windows + X and select "Device Manager".
2. Look for any devices with a yellow triangle, indicating an issue.
3. Right-click the device and choose "Update driver" or "Roll back driver" if the issue started after a recent update.

Step 3: Run System File Checker (SFC)

Corrupted system files can lead to this error. The SFC tool can repair these files.

1. Open Command Prompt as Administrator.
2. Type sfc /scannow and press Enter.
3. Wait for the process to complete and follow any on-screen instructions.

Step 4: Check for Hardware Issues

Faulty hardware components such as RAM or hard drives can cause this error.

1. RAM Check: Use the Windows Memory Diagnostic tool.

   • Type mdsched.exe in the Run dialog (Windows + R) and press Enter.
   • Choose "Restart now and check for problems".

2. Hard Drive Check: Use the CHKDSK utility.

   • Open Command Prompt as Administrator.
   • Type chkdsk /f /r and press Enter.
   • Follow the prompts to schedule a check on the next restart.

Step 5: Restore System to a Previous State

If the error started after a recent change, restoring the system to a previous state might resolve the issue.

1. Type rstrui.exe in the Run dialog (Windows + R) and press Enter.
2. Follow the instructions to restore the system to a previous state.

Step 6: Repair Windows Installation

If none of the above methods work, consider repairing your Windows installation.

1. Create a bootable Windows installation media.
2. Boot from the media and select "Repair your computer".
3. Choose "Troubleshoot" > "Advanced options" > "Startup Repair".

Examples

• Updating a Driver via CMD: While Device Manager is the primary tool for driver updates, you can use PowerShell or CMD for specific tasks, such as using pnputil to manage drivers.

  pnputil /add-driver <path_to_driver> /install

• Running SFC in Safe Mode:

  sfc /scannow

• Running CHKDSK:

  chkdsk C: /f /r
