Svchost.exe is constantly using my HDDs causing them to run very slow

post #1 of 9
Thread Starter 
So a month ago I've noticed that my 500GB Seagate HDD is constantly writing/reading something causing it to be noisy and slow. Somethimes it would run so slow that HD Tune Pro would show read speed below 1mb/s. Resource Monitor wasn't showing any activity so I thought that the drive is simply dying, it's 8 years old after all. So I've disabled the drive and moved on. After awhile I've noticed that the same thing is happening to my 2TB Seagate drive. So I've started to investigate on the software side and found out that if I kill one particular svchost.exe process, the problem goes away. Then I've started investigating services that run under that svchost process and I found out that if I pause and resume the "Winmgmt" service the problem goes away.

Does anyone have any idea why is this happening?

Pausing and resuming the "Winmgmt" everytime I start the PC is very unconvinient as you may imagine, so please help me come up with a permament fix for this.

Would it be safe to completely disable "Winmgmt" service? What does it do?

Specs:
Windows 10 Pro 64
HDD1: Seagate ST3500320AS
HDD2: Seagate ST2000DM001
System HDD: Toshiba THNSNH256GBST

EDIT: Uninstalling MSI Gaming App solved the problem. Well done MSI - really nice software.

Could you post your computer specs as well? Do you have Pagefile enabled to write to your HDDs?

 

Did you run a malwarebytes scan? To make sure you dont have any virusses?

I never played around with pagefile settings so it's set to Auto.

That was the first thing I did when I've noticed the problem, but it found nothing.

Does windows use a HDD for backups, restore points or Pagefile? Try turning them off.

 

You got 16gb ram, so using your HDD as ram because youre exceeding your ram seems unlikely.

I disabled the Pagefile - no difference. Restore was enabled only for the system drive, disabled it - no difference. Backup is disabled. But if it would be any of those things it would show up in the Resource Monitor. Disk Monior in HD Tune also doesn't show any activity, yet the drives are doing something.

I did a benchmark for every drive in HD Tune and this is how it looks:

HDD2: Seagate ST2000DM001

After pausing and resuming Winmgmt:

That was freshly after starting the system so it's not that bad, but if I would let it run for a few hours it would get even worse.
But sometimes it's bad from the start - here is a extreme example from earlier today:

I'm not sure if the system SSD is affected, it did speed up a bit after pausing Winmgmt in this test, but it could have been just doing something while the first test was running - its a system drive after all. I will try to let the system run without touching Winmgmt for a while and then do another test.

It's not the Winmgmt.exe that I have problem with, it's Winmgmt service:
http://servicedefaults.com/10/winmgmt/
I can't even see Winmgmt.exe running in task manager.

The two should still be related from what I can see. That winmgmt.exe and the service with a similar name use each other.

About "svchost.exe", you can find a more complete process name by using the Resource Monitor tool instead of the Task Manager tool. The name you see there might help finding your problem with Google. When you look at one particular process there, you can also research which files it has open on disk. Perhaps that might help somehow with finding something about the problem.

I've solved the problem cheers.gif

So I've noticed that pausing and resuming Winmgmt service had a side effect of svchost.exe starting to use over 30% of CPU. You can see that the benchmarks I did after pausing Winmgmt have 51% CPU usage. So I've killed the svchost.exe in task manager and then MSI_Activex_service.exe started using around 30% of CPU so I googled it and that's what came up:
https://forum-en.msi.com/index.php?topic=272127.0

So then it hit me that the problem started occuring after I've installed MSI GTX 1070 Gaming X and along with it MSI Gaming App. Uninstalled MSI Gaming App and the problem is gone! biggrin.gif

I've tried downloading the new version - 6.0.0.17 - of MSI Gaming App to see if they've fixed it (I had 6.0.0.08) and it's still the same. After I install it, my HDDs instantly start "doing something" and when I uninstall and restart the problem goes away. I would never suspect that software designed to control GPU will somehow mess with HDDs.

So a big round of applause to MSI for creating such a wonderful piece of software applaud.gif

Thanks for trying to help guys.
