Hi Alex,
Thank you for posting your query in Microsoft Community.
- What is the make and model of the computer?
- Which security software is installed in the computer?
- Do you remember making any specific change in the computer prior to the issue?
This could be due to several reasons and diagnose the issue, let's try the following methods and check.
Method 1:
Start the computer in Safe Mode and check if the issue persists. If the issue does not persist in safe mode, place the computer in clean boot state and check.
Step 1:
Start the computer in Safe Mode
Safe mode is a troubleshooting option for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows
are started. The words Safe Mode appear in the corners of your monitor to identify which Windows mode you're using.
a. When you hit the power button, hold down the
Shift key when clicking the Restart button.
b. The next screen will present you with three options. Click
Troubleshoot.
c. Next, hit
Advanced options followed by Windows
Startup Settings from the next screen.
d. Your PC will now be rebooted to enable the advanced parameters, which include Safe
Mode as well.
Step 2:
Perform Clean boot to avoid any third party software conflict.
To help troubleshoot error messages and other issues, you can start Windows by using a minimal set of drivers and startup programs. This kind of startup
is known as a "clean boot." A clean boot helps eliminate software conflicts.
Placing your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. You need to follow
the steps from the article mentioned below to perform a Clean Boot.
How to perform a clean boot in Windows
Note:
Refer "How to reset the computer to start normally after clean boot troubleshooting" to reset the computer to start as normal after troubleshooting.
Method 2: Run System File Checker tool
System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.
Press
Windows key + X and click Command Prompt (Admin)
Type the following command and press
Enter
sfc /scannow
Note: Do not close this Command Prompt window until the verification is 100% complete.
The scan results will be shown after this process is finished.
Hope this information is helpful. Please feel free to reply in case you face any other issues with Windows in future.
