Question New Upgraded PC - FPS stuttering same as old one. Why?

[Kairosmic]

I was experiencing issues on my old pc, so I upgraded every part except an old HDD and SSD.

Asus Prime z790p
I7 13700k
RTX 4070
2x16GB DDR5 6000
H150i elite 360mm cooler
Corsair 850W gold (no overclocking)

Reinstalled windows on my new SSD, 990 Pro 2tb, and I am still getting FPS issues. Desktop and games will skip frames and audio will cut with it every once in a while. I’ve literally done everything I could to fix the problem EXCEPT replace/deactivate my old HDD. Could a faulty drive be the cause to these problems? I have nothing else to check. I’ve checked every new component and have a clean windows 10 install with my account. I mean at this point the drives are all that’s left. Would my old HDD/SSD cause these problems? I have a mediocre 8tb sea gate that’s very slow, and 2 970 evos. Then my new SSD. I just need to know if one of those 3 (besides my 990 pro) would be the cause of fps issues. That’s all I can check at this point. Would unplugging my old drives and just running the 990 pro help?
I’ve been working on this for 2 weeks which is why I’ve completely overhauled my build.

Heavily fragmented files on a spinning hard disk result in sluggish read/write speeds. SSDs are much faster and do not have the same head positioning delays. Even old SATA SSDs (970s?) should provide sufficient performance.

Try running a few games with all relevant files copied from the hard disk to a solid state drive, then disconnect the hard disk during gaming.

If the glitches are reduced, consider buying a couple of 4TB SATA SSDs to replace the 8TB Seagate.

I'd also recommend checking the integrity of the Seagate hard disk. It might be starting to fail.

If testing shows the hard disk is still in pristine condition (no surface errors), perform a full defrag.

On the new PC use Task Manager, Resource Monitor, and Process Explorer to observe system performance.

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

First observe system performance doing things that do not stutter.

Second observe system performance doing things that do stutter.

Look for what changes being the not-stuttering observations and the stuttering observations.

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

Pay attention to what the drives are doing.

I think it’s a bad hard drive. I’ve said “I think” for every time I’ve tried fixing it. Gone through everything I could think of EXCEPT the old HDD. And I was getting BSOD’s on my old system before I upgraded. Now I’m just getting the frequent stutters. It’s a very slow HDD as well. Download speeds are horrible and it runs very slowly. My 970s should be fine. But I think I’m going to format the HDD and unplug it to see if that was the issue. It comes down to storage because I’ve tried everything else. And it did seem like specific games installed to the HDD were causing TERRIBLE stuttering. Battlefield 2042 for example. I played for about 5 minutes and got unplayable skipping. Great FPS, average 200, but skipping frames like a b****

Had issues with my old pc, BSOD’s and stuttering like crazy. Built a new one using the same old HDD (8TB sea gate junk speed) with a bunch of games and stuff on it. New specs:

Asus z790p
RTX 4070
I7 13700k
H150i elite cooler
2x16GB DDR5 6000
Corsair 850W gold (no overclocking)

like I said, everything in the pc is new except an old HDD that I still have. I reinstalled windows 10 onto my new SSD and boot off of it, but I’ve noticed that I’m getting audio cuts and frame skips/stutters on the desktop and in games just like it was on my old build. All new parts except the HDD, checked every part to make sure they’re operating. It realistically couldn’t be anything else but my storage because I’ve checked EVERYTHING ELSE. Which is why I have a new build. Would this old, slow HDD cause stutters in game and on desktop? I run average 200fps on ultra settings, but I’ll skip a frame and sometimes it gets severe on bigger map games, like bf2042, warhammer 3, ecta.

All my big games are on the HDD, but like I said, I get the stuttering on the games and on the desktop. Would my HDD be causing that if it was going bad? I’m going to format and unplug it after work to see if that fixes it. I’ve gone through everything I can think of. Diagnosed everything on my old pc, and now with all new parts EXCEPT HDD still getting it.
