Windows 10: System Clock Running Slow

My system clock consistently runs slow. Using a stopwatch, I've timed that 60 seconds on my system clock takes 74 seconds in real time. I've validated this using a standalone stopwatch, and the stopwatch app on my phone and can upload video to clearly demonstrate it.I've tried the following methods of troubleshooting:- Replaced the CMOS battery on my motherboard twice - no battery fixed the problem.- Set up automatic sync to internet time. This works only when the sync is scheduled, and the clock immediately starts to drift significantly out of sync afterwards.- Changed automatic sync servers.

Clock Running Slow ~ System Tray Clock running slow !

Hi <

In the last two days the System Tray Clock on my Dell PC has been running slow , it seems to be running progressively slow , that is the longer it is running the greater the inaccuracy , resetting the clock manually or automatically does just that , but
it soon becomes apparent the speed of the clock is not accurate. As a guide in the last ten minutes the PC Clock has advanced three minutes.

The PC is running Windows 10 .

Just checked ...when I send an email it is correctly timed (that is NOT using the time displayed on system tray clock)

Any help correcting this would be welcome!

Hi Anju,

Thank you so much for engaging on this problem, in answer to your questions:-

• 
  Have you made any changes to the system prior to the issue? A: The only change I am aware of was adding the 'Pinterest' app .
  
• 
  Have you installed all pending updates? A: All updates have been added .
  
• 
  Did you experience this issue on a local account or a Microsoft account? A: I do not understand this question, but my guess is a Microsoft Account as I am not aware of a Local Account
  
• 
  Have you replaced the CMOS battery in your computer? A: No, the computer is less than 2 years old.
  

I am not sure how to implement this advice ; "I suggest you to sign out from the current user account, restart the pc and login to the Admin account or the Microsoft account to test if that helps with
this issue."

I have conducted the System File Check procedure , no issues were discovered.

I will look at trying the other advised procedures.

When I started the PC today , the clock immediately displayed the correct (local) time , but it was running slow immediately, so in twenty minutes the clock was 15 minutes behind time.

I have noticed that some other display issues seem slow , for example, drop down menus are slower to 'open/drop down' and when using the backspace key to delete text , it is slower at switching from one press /one backspace to continuous backspace when the
key is held down, if that makes sense!

The Task manager processes screen (to the inexpert) does not seem to show any slow processing / heavy demand. I have done Disk Clean -Up and checked for defragmentation (not required).

Thanks for your help on this!

Hi Chris,

Thank you for posting your query in Microsoft Community.

I understand your concern, and we in Community will try to help you in the best possible way.

I understands that your System tray clock on the Dell PC has been running slow,
this issue occurs if the system file is corrupted or damaged.

Please provide more information to help you better:

• 
  Have you made any changes to the system prior to the issue?
  
• 
  Have you installed all pending updates?
  
• 
  Did you experience this issue on a local account or a Microsoft account?
  
• 
  Have you replaced the CMOS battery in your computer?
  

If the computer is 3 or more years old it’s time to replace the battery on the motherboard.

I suggest you to sign out from the current user account, restart the pc and login to the Admin account or the Microsoft account to test if that helps with this issue.

I also suggest you to install any pending Windows updates on the pc to check if that helps. Updates are additions to software that can help prevent or fix problems, improve how your computer works, or enhance your computing experience.

If issue still persists, I suggest you to follow the methods below and check if it helps:

Method 1: Clean boot

I suggest you to do a clean boot and check if any third party apps are causing the issue.
Placing the computer in a clean boot state can reduce software conflicts and help identify the root cause of the issue.

Please refer to the article below for steps to perform a clean boot.

Disclaimer:Once you are done with the troubleshooting, perform the steps in "How to reset the computer to start as usual after troubleshooting with clean boot "to reset computer as usual.


Method 2:SFC

System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.

Please refer the link below to run a system file checker scan and check if that helps.

System file check (SFC) Scan and Repair System Files & DISM to fix things SFC cannot

Method 3: Run DISM or System Update Readiness tool

Let’s run the Deployment Image Servicing and Management (DISM) tool and check if it fixes the issue. This tool will try to fix the corrupt operating system files.

1. Open an elevated command prompt. To do this, Right click on Start and select Command Prompt (Admin). If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.

2. Type the following commands. Press Enter after each command.

DISM.exe /Online /Cleanup-image /Scanhealth

DISM.exe /Online /Cleanup-image /Restorehealth

3. Close the command prompt then check if it fixes the issue.

Hope this helps. If the issue persists please get back to us we will be happy to help you further.
