[Vezovi]

Sure, many times

1. Update/Install/Reinstall Intel® Management Engine Driver for Windows 8.1* and Windows® 10 - Version: 1909.12.0.1236 (Latest) - Date: 3/26/2019 (downloads\ME_SW_1909.12.0.1236\Cons\ME_SW_MSI\SetupME.exe): https://downloadmirror.intel.com/28679/eng/ME_SW_1909.12.0.1236.zip
   
   
2. And the Chipset INF Utility for Mobile Intel® HM370 Chipset - Version: 10.1.18 (Latest) - Date: 11/28/2019: Chipset INF Utility
   
   The readme says:
   Read More:

   INSTALLING THE INF FILES AFTER OS INSTALLATION
   
   By [supported Windows OS] it is meant a Windows operating system that is listed in section 2.
   Some Intel(R) chipset platforms already are supported by supported Windows OS so it may not be necessary to use the INF files provided by this software to update the supported Windows OS.
   The following steps describe the installation process of the supported Windows OS INF files. You may need to repeat these steps to update all Intel(R) chipset devices not supported by supported Windows OS.
   
   1. Copy the contents of the to the root directory of a removable media, such as
   a USB flash drive (UFD) or floppy disk (A:\).
   2. Close all programs currently running on the system.
   3. Click on Start.
   4. Select Settings.
   5. Select the Control Panel.
   6. Double-click on the System icon.
   7. Click on the Hardware tab.
   8. Click on the Device Manager button.
   9. Select "Devices by connection" under the View menu.
   10. Click on MPS Uniprocessor PC -OR- MPS Multiprocessor PC.
   
   NOTE:
   Only one of the above items will be displayed for a given system.
   
   11. Click on PCI bus.
   12. Right-click on the line containing the description PCI standard host CPU bridge
   -or-
   PCI standard ISA bridge
   -or-
   PCI standard PCI-to-PCI bridge
   -or-
   PCI System Management Bus
   -or-
   Standard Dual PCI IDE Controller
   -or-
   Standard Universal PCI to USB Host Controller
   (This line will be selected.)
   13. Select Properties from the pull-down menu.
   14. Click on the Driver tab.
   15. Click on the Update Driver button.
   16. Supported Windows OS will launch the Upgrade Device.
   Driver Wizard. Select Browse my computer for the driver software.
   17. Enter "X:\" in the Combo Box, where X is the drive letter
   for your UFD or floppy disk
   18. Ensure that the Include Subfolders checkbox is checked.
   19. Select Next.
   20. The window Will Display the Device that was installed.
   21. Select Close.
   22. Reboot the system if prompted to do so.

   Honestly, I didn't see that "MPS Uniprocessor PC" or "MPS Multiprocessor PC" strings in device manager; a search on internet shows old dates (from 2000 and 2007).
   It could be things changed in the years and they didn't update the readme.
   Now, I think the path to follow (in device manager) is:
   - "ACPI x64-based PC", "Microsfot ACPI-Compliant System", "PCI Express Root Complex", "PCI standard ISA bridge"
   OR
   - "ACPI x64-based PC", "Microsfot ACPI-Compliant System", "PCI Express Root Complex", "PCI-to-PCI bridge"
   OR
   - Both?
   
   I have both (but I'm using an AMD system):
   
   
3. Finally, try the nvidia studio driver:

   Within GeForce Experience, click the menu (three vertical dots in the top right corner) to reveal a toggle and select the driver of your choice.

   If it's not available, download and install (custom option, Perform a clean install) the nvidia studio driver (442.92 - 2020.4.16 - 530.23 MB): http://pl.download.nvidia.com/Windo...ok-win10-64bit-international-nsd-dch-whql.exe

There wasn't any drivers that should be updated. Problem is still there :/

 

[xilolee]

Let's see if you get the problem with the clean startup:

• Start, searchbox, type msconfig, press enter.
• In the new msconfig window, in General tab (default opened tab), click Selective startup and untick/deselect/uncheck Load startup items.
  Only Load startup items should be unticked, the other two must be ticked.
• Go to Msconfig Services tab, tick/select Hide all Microsoft services.
  Don't forget to hide them!
  Disable the remaining NON-windows services.
  I.e., DON'T disable windows services!
• Click ok, reboot and check if the problem reappears.

Already tried that, no change

And in safe mode?

 

[Vezovi]

I can't run latencymon in safe mode

 

[xilolee]

I can't run latencymon in safe mode

But you can verify there are, or there aren't, the issues (popping, crackling, stuttering...).

 

[Vezovi]

Cracklings or poppings are rare now even on normal boot, but i think these latency problem (wdf01000 mostly) affect how mouse behave (it's kinda delayed/floaty). In bios it's not that much, its snappier.

 

[Vezovi]

I have found some interesting stuff: intel fix
But i don't know is it safe to turn off so many system devices, specially on laptop?

You can try to stop some services instead: Black Viper's Windows 10 Service Configurations | Black Viper | www.blackviper.com

I just registered for writing here. I have fully same problem with him. I cant fix for 1.5 years but I found why it happens. Ec Firmware or Bios causes this. I have the same problem when i am doing fn+1 (sometimes it happens randomly) ACPI.sys latency jumps. I found a EC Firmware update and flashed it. Problem didnt fix and it happens more often... So you cant do something on Windows. Just wait for the new updates. I have Clevo laptop and they did last update in 2021. Probably they wont fix it. I promised to myself for buying electronics from known manufacturers.
