System stutter problem

[srK122]

So, I've been getting sound and system stuttering, mainly while scrolling and opening browser tabs and it's very weird cause My CPU is fine, (FX 8350 with no voltage or fps drops in games), RAM never goes up 6k out of 8k.
I've been suspecting 2 things, either my HDD (a samsung 8yo HD) or my GPU r9 270x is faulty. Thing is, i tested my HDD health and it is fine, i've ran all kinds of benchmarks on my GPU and no problems what so ever.
From time to time i get artifacts randomly (mainly if i run a 2 monitor setup), my GPU warranty wears off next month so i am worried it could be it, but i don't want to waste my time sending it to RMA and i turn out to be wrong.
My MOBO is a sabertooth 990fx r2.
PS: Problem persists with newly installed OS

Can you tell me what PSU you have?

Make sure everything is up to date, and maybe reinstalling your drivers will fix it.

Okay if you can I would update your audio drivers and see if that helps. If not I would try a different power supply and see what happens.

Well it is hard to get a new PSU that supports this PC setting based on a guess, i did a fresh install of everything, that's the problem

Then update your audio drivers. here is the driver download location http://www.asus.com/us/Motherboards/SABERTOOTH_990FX_R20/HelpDesk_Download/

i've made a fresh install last month.. Last audio driver update for the MOBO dates from last year, so there's no use installing it again

 

[subvoltic]

Yeah, did you install the audio drivers when you reinstalled windows?

 

[srK122]

Yes, also, i use the HDMI so sound goes through GPU to my monitor (it has speakers on it).
EDIT: Although i dont think system would stutter over a audio driver issue, it really freezes for like 1~3 secs

I had an audio issue on an old hp years ago that did the same thing was a pain to fix, went through 5 audio drivers until one finally fixed it. That's why Ive been suggesting that's the issue but it could very well be another problem.
