Quick Note Before You Begin

Before diving into fixes, make sure to do the following checks:

  • Check for Recent Changes: Think about any new hardware, software, or updates installed just before the error appeared.
  • Have Your Windows Version Ready: Knowing your exact Windows 11 version helps when searching for specific patches or support.
  • Ensure Power Stability: A stable power supply is important; unexpected shutdowns can cause errors.

Step 1: Restart Your Computer

How to do it:

  1. Click on the Start button.

  3. Choose Restart.

After the restart, check if the error still appears. If it does, move on to the next step.

Step 2: Run Windows Memory Diagnostic Tool

Follow these steps:

  1. Press Win + R keys to open the Run dialog box.
  2. Type mdsched.exe and press Enter.
  3. Choose Restart now and check for problems.
  4. Your PC will restart and test your memory. This may take several minutes.

If errors are found, you may need to replace your RAM or consult a professional technician.

Step 3: Update Device Drivers

To update drivers:

  1. Right-click on the Start button and select Device Manager.
  2. Look for any devices with a yellow warning icon.
  3. Right-click the device and choose Update driver.
  4. Select Search automatically for updated driver software.

Make sure especially to update drivers related to your graphics card, network adapters, and storage controllers.

Step 4: Run System File Checker (SFC) Scan

How to run SFC scan:

  1. Press Win + S, type cmd.
  2. Right-click Command Prompt and select Run as administrator.
  3. In the Command Prompt window, type this command and press Enter:
sfc /scannow

The scan will take some time. If it finds and fixes problems, restart your computer afterward.

Step 5: Check for Windows Updates

Microsoft regularly releases updates that fix bugs and improve stability. Installing the latest updates can resolve system errors.

  2. Go to Windows Update on the left menu.
  3. Click Check for updates.
  4. Download and install any available updates.

How to uninstall:

  1. Open Settings and go to Apps > Installed apps.
  2. Find the recently installed software.
  3. Click the three dots next to it and choose Uninstall.
  4. Follow the instructions to remove it.

After removal, restart your computer and check if the error persists.

Step 7: Use System Restore

  2. In the System Properties window, click System Restore.
  3. Choose a restore point dated before the error began.
  4. Follow the wizard to complete the restoration process.

Your PC will restart during this process. Check if the error is resolved afterward.

Step 8: Check Hard Drive for Errors

Hard drive issues can also cause system crashes. Running a disk check can identify and fix errors on your storage device.

  2. Type the following command and press Enter:
chkdsk /f /r

You will be asked if you want to schedule this check on the next restart. Type Y and press Enter.

Restart your computer, and the disk check will run before Windows loads.
