PC stuttering every few seconds

[Deadzoke]

Hello there!

 

So, I have a small "huge" problem with my computer. It keeps stuttering every few seconds as I said in this topic's title (I have a video attached with a webpage opened at the www.testufo.com, that is used to check framerates, so you can check by yourself), so I tried a few things that didn't quite worked out for me and, while doing so, I've noticed some strange things on my computer as well.

 

So I will start to explain the situation: I got my custom build PC, wich parts I will list at the end of the topic, at november 2019; installed all the required/recommended drivers (from all the websites of the manufacturers, like MSI for the mobo and AMD for the CPU); all did well at the beggining, except at the time i didnt got the windows key and the pc was starting stuttering (so i bought the windows key right away and reinstalled, and all worked fine); a few months later (arround january) the pc started stuttering like in the video, so i started searching and after some research I noticed that my latency was high; ran a few tests etc and the problem was solved, and i didn't knew how; and today it started again after the energy here went down, the pc shutted down, energy came back, and i started the pc and the stuttering stated again and with this I noticed a few things:

- my MSI Creator Center now doesnt recognize the CPU, when before, it did (i can't see it in the monitoring tab and when i set the performance to "High Performance", only the GPU changes and when i try a custom performance, only the cpu is showing) (i dont know if the power loss of today was the cause of this, i didnt check that for a while);

- when today I tried to reinstall the nvidia driver, with the clean installation, between the time when the driver was unninstaled and the new one got installed, the stuttering disappeared;

- with latencymon, the highest meadured interrupt to process latency was 180, the average latency is arround the 30s and with spikes to the 80s for no aparent reason, the highest DPC routine execution time was the "nvlddmkm.sys - Nvidia Windows Kernel Mode Driver, v445.87" with 581 and the highest ISR routine execution time was the "dxgkrnl.sys - DirectX Graphics Kernel" with 216, all this while just working on the pc, no games involved;

- MSI Afterburner doesn't open, or better, it opens and closes, opens and closes, opens and closes, etc;

- i ran a few more tests and i executed some "fixes" but none of that worked out, and while i was tapping this message, sometimes the website testufo got stable, without stuttering;

- i noticed now as well that the pc stutters when i do something more than just stand still writing, like uploading the video, opening and closing many times the start menu or just opening a tab...

 

My PC's specs:

- Monitor 1 : ASUS VG248 144Hz
- Monitor 2 : ASUS VX248
- Monitor 3 : Samsung S24D300
- Motherboard : MSI Prestige X570 Creation
- Processor : AMD Ryzen 9 3900X
- Cooler : CoolerMaster ML360R RGB
- Graphic Card : MSI Gaming Z Nvidia RTX 2070
- RAM : 4x8GB G-skill Trident Z 3600hz CL16
- SSD 1 : 500GB SSD Samsung 970 Evo Plus M.2 NVMe
- SSD 2 : 1TB SSD Samsung 860 Evo SATA

Any help is welcome and i'm willing to test and answer all the help you can give me guys!

Thank you! :)

Maybe power loss reset something in hardware, don't know... tried system restore?

Why would you record your computer screen via external camera and not a screen recording software?

CPU spikes are normal behavior under heavy load, and if it can't keep up things will hang...

Frames per second don't matter if the picture on the screen doesn't change, so that is one weird test.

do you have any changes applied in bios? any cpu or ram overclock? or in ryzen master?

Didn'd tried system restore because it was my last hope, altough it doesnt change much, id like to keep that to last since this problem appened before for no aparent reason.

I recorded with my phone so the pc was in a minimum load.

Yes, i know CPU spikes under heavy load are common, but with nothing appening, CPU in 2 or 3 % and still stuttering its wat's worring me the most...

I ran this test because is a countinuous sliding image, and its easy to se the stuttering instead of moving windows or moving the mouse, wich happens as well.

I have a change in the bios for Virtual Machine support, since it is needed for working proposes, but when the first situation of stuttering happened this wasnt active yet. I had ram memory overclock as well, but i reverted it a couple months ago.

After some testing I figured it out and it was the MSI.CentralServer.exe process. I opened the task manager and i noticed the process running at almost 1gb RAM (and checked some foruns and it was safe to stop), and when I stopped it, the stuttering stopped compelitely, but there's a downside... Now the MSI Creator Center does not work, it is stuck in the "Waiting for SDK initialization" state (Screenshot_1.png).

 

Can someone help me with this please?

And why does my CPU settings doesn't appear in the MSI Creator Center? Oh, and the MSI Afterburner cant open either maybe because of the same issue.
