Hi,
Welcome to Microsoft Community. Your interest in Windows 10 is much appreciated.
When the system processor or Random Access Memory (RAM), or hard disk is not working properly, it will give the system alert using the beep sound.
I would recommend you to check if the RAM and the hard disk are working properly.
Method 1:
You can also change the Windows Sound scheme as "None" and check for the issue.
a. In search, type Sound and hit Enter.
b. On the Sounds tab, select "No Sounds" under
Sound scheme, click Save As.
c. In the Save Scheme As dialog box, type a name for the new sound scheme.
The new scheme is displayed in the Sound scheme box.
Check if you still come across the Beep sound.
Method 2:
Run the System Maintenance troubleshooter and check the status.
1.Open Control Panel.
2.Click on ‘search’ and type ‘Troubleshooting’ and select ‘Troubleshooting’.
3.On the left pane click "View all" and then click "System Maintenance" and run the troubleshooter.
4.Once the troubleshooter is run, restart the computer and check the status.
Also install all the Windows updates and check.
Method 3: Run the DISM Tool.
If the issue persists, I would have you run the DISM tool to check the system health and will try to restore the files.
-
Click on 'Start'.
-
Enter 'Command prompt' in the Search box.
-
In the list of results, swipe down on or right-click Command Prompt, and then tap or click
'Run as administrator'.
-
In the Administrator: Command Prompt window, type the following commands. Press the Enter key after each command:
DISM.exe /Online /Cleanup-image /Scanhealth
DISM.exe /Online /Cleanup-image /Restorehealth
To close the Administrator: Command Prompt window, type Exit, and then press Enter.
Note: The tool might take 15-20 minutes to finish running, so please do not cancel it.
