New build; system stuttering

Too long since I've done this kind of troubleshooting.
Finally built a new machine to replace the good ole i7-920.

Ryzen 2700
MSI X470 Gaming Pro Carbon
2x Patriot VIPER 4 8gb sticks
Seasonic FOCUS Plus 750w Platinum
MSI Radeon RX 580 GAMING X
WD Black 500gb NVMe
Windows 10 Pro

After initially installing Windows, I'm pretty sure everything was fine and dandy.
Unfortunately I didn't pay enough attention.

After installing or updating drivers, I'm getting micro-stuttering that's impacting the whole system.
Mouse cursor stalls for a second.
If typing in notepad, text input stops.
Screen doesn't refresh/webpage stalls displaying.

I've tried:
downgrading drivers
removing drivers
upgrading BIOS
downgrading BIOS

keyboard is wired, mouse is wireless; but since it's not just input devices impacted, I know it's not those.

I have not yet tried booting in to a Linux Live yet, and plan on that sometime after I get back from work.

When in UEFI, there are zero stutter issues though.

halp?

What drivers? Are you getting latest from manufacturer or just letting Win 10 install whatever the hell it wants?

Currently using drivers downloaded from AMD for graphics and chipset.
Downloaded and installed Intel drivers for LAN.
Downloaded and installed Realtek drivers.

When it was just the initial drivers installed by Windows, it wasn't being problematic.
May have just been timing or coincidental.

I would download the latest "everything" directly from the MSI website for your exact motherboard.

(except graphics driver obviously)

Using a VRR monitor?

I'd probably install windows again

I would expect them to just provide (and maybe repackage) drivers supplied by manufacturer, but I'll give it a go.

not sure what VRR stands for so... I would say no

considering it's a less than 1 week old install, with nothing other than some basic apps (chrome, firefox, vlc, 7zip), I'm gonna say no. Not yet.
Not even regular use until last night.

Check your dpc latency.

so... the chipset drivers I downloaded directly from AMD appear to have been the cause...? wtf.
18.10.0813 from AMD.
17.40.3765 from MSI.
Issue appears to be resolved, or at least not occurring, with 17.40.3765.
I probably would have maybe eventually got to this, but your suggestion bumped it up the list! thanks!

I did... but had no real idea wtf I was looking at.
Plus there were several processes reporting what may have been high numbers; to include Windows drivers.
I think it was a Realtek hdaudio.sys and NDIS.sys that had the highest numbers.

How frequent are the stutters? It may be worth checking temperatures also, in case the system is thermal throttling heavily.
