Question Strange issue that I can't seem to resolve.

[LVFF]

Hi everyone, new around here and hoping someone can give me some advice. This is a little tricky to explain.
What it is, is I get fps drops quite consistently between every 30 seconds, this varies as sometimes it can happen after a minute apart or less. When these drops occur, it feels like a slowdown/slow motion effect that lasts for a split second and it's very noticeable. This only happens in some games, games that I find it mainly happens on is Tarkov, Fallout 76, and Rust. I know these games are not really optimized, however no one else I know has this issue I'm facing, even trying these games on a friends rig that's more outdated than my own doesn't have this issue.
I've monitored all temps, but they seem to be fine. Gpu never hits over 60c under load, and cpu averages 60c/70c when gaming.

PC Specs are:
RX 6700xt
Ryzen 5 5600x
ROG STRIX B450-F GAMING
Corsair Vengeance 16gb (2x8gb) CL18
Cooler Master ml120l v2 AIO
Corsair CX650F RGB PSU
Crucial P3 500gb M.2 NVMe (boot drive)
Kingston A2000 1tb M.2 NVMe (secondary drive)

Things I have tried:
New CPU
New GPU
New RAM
New PSU
New case
New drives including boot drive
Fresh install of windows (multiple times from windows 10-11)
Over clocked CPU & Undervolted it
Ram in XMP/without
Updated BIOS
Cleared CMOS/set bios to default
New chipset drivers
DDU all old drivers
Freesync on and off
Resizeable bar on and off
Changed some AMD Adrenalin settings

The only 2 things I haven't changed are the AIO and motherboard, and this issue was a thing before I changed parts. And I highly doubt my AIO could be causing these fps problems.
About a year and a half back, I updated my motherboard BIOS and around the time of doing that, this issue started as before this the problem never existed. Could this be the culprit? If so, I have no idea why as my system is fine otherwise. It's just in certain games.
I'll also post screenshots of this drop happening, both screenshots are like a fraction apart in time.

Use Task Manager, Resource Monitor, and Process Explorer to observe system performance.

Use all three tools but only one tool at a time.

(Process Explorer, Microsoft, free):

https://learn.microsoft.com/en-us/sysinternals/downloads/process-explorer

You will need to have the monitoring window open in order for continuous observation.

First observe system performance while not gaming. Then again while gaming.

Determine what system resources are being used, to what extent (%), and what is using any given resource.

Pay attention to resource changes when fps drops. The 30 interval may appear in some pattern.

Possibly some background process tying to update, gather data, or simply "phone home".

Take your time, be methodical, and do not immediately react to something that may be the problem.

Do additional testing to ensure that the observations are consistant and confirmable.

He can also try a clean boot to rule out most software besides windows updater I believe. @LVFF Here is how you can perform a clean boot. This disables all services that are not windows related effectivley eliminating software as a culprit. It the issue happens after doing a clean boot and you only open the game to test then it is most likely something besides software.

Thank you, I will give clean boot a go first as resource monitor and so on I've no clue what I'm looking for.
I'll report back after the clean boot

Ok so just tried a clean boot and launched Fallout 76, reason for this game is it happens more frequent compared to the other games mentioned. Still, same issue. I will try get my head around using Resource Monitor, and Process Explorer and see what I can dig out from that. If no luck, I may have to invest in a new motherboard and hope for the best.

Maybe flashing/reflashing the latest non-beta BIOS available to your motherboard could solve the issue. You said it all started after a BIOS update, right? You could go back to the BIOS version you had no issues with.

My motherboard doesn't support BIOS flashback unfortunately, and I can't think to why it would be a windows issue as I've fresh installed god knows how many times. It has to be the motherboard but I can't figure what would be causing it.

Have you tried updating the BIOS with the updater tool inside BIOS? You should be able to flash any compatible BIOS, old or new...

I have tried to revert back to an older BIOS version, but I can only go so far back as my mobo never supported 5000 series when they first came out, going back further than that I'm not sure if it would cause issues, and I no longer own my old cpu

You can check which BIOS versions started supporting the 5000 series CPUs and try one after that.

I've tried that, but no luck. This problem has been going on way before the 5000 series came out.
