Could the power supply unit have harmed your motherboard?
Here’s the rewritten version:
A few months back, my computer began stuttering or freezing suddenly. I searched online for solutions but nothing resolved the problem.
I replaced every part of my PC, swapped out my old storage drives for new ones, and installed a different operating system using two fresh drives. I also updated the motherboard, which appeared to solve the issue. However, it started stuttering again, though much less intensely.
Last week, I upgraded my BIOS to the newest version, and after that the stuttering returned to its previous level with the old motherboard.
My friend suggested the power supply unit (PSU) might be the culprit. I wasn’t sure, but a faulty PSU could potentially harm the motherboard—even though I used another reliable PSU before it didn’t help. My current PSU (Corsair RM750) is three years old and brand new.
I attempted a clean Windows installation, which reduced the stuttering but didn’t eliminate it entirely. Certain games, such as The Finals, performed better, while most open-world titles still experienced stuttering. I also built a second PC using remaining components, including my old motherboard (except the same OS drive from another PC), and it also stuttered.
My PSU is still under warranty, so I’m considering returning it for repair.
If anyone has any advice or information that could help, please let me know. Feel free to ask for more details. Thanks for reading!
Additionally, during page navigation such as on Steam or YouTube, the same freezing occurs while images and thumbnails are loading.
Hard problems often stem from a failing power supply unit, but identifying the issue can be tough unless it's clear. It's also not feasible to check a motherboard for electrical faults due to its complexity.
Checked for malware and unusual tasks in Task Manager. Hardware tests didn’t reveal an issue unless the SSD was failing. Possible causes shifted to RAM or the motherboard. The problem reappeared shortly after the Windows installation.
I ran Malwarebytes and didn't detect anything. Also performed a Windows Defender scan, but nothing found. No unusual processes have been observed so far. I've changed my operating system's SSD twice, and even with a brand new m.2 SSD, I still experience stutters. The issue reappeared after updating the BIOS to the latest version, not during a standard Windows installation. After a clean Windows install, the stutters decreased significantly. I also tried installing Windows on an older motherboard, but it didn't resolve the problem, which is unusual since it worked with the new one.
So I just created a discoveryt, that when scrolling in some windows, it won't stutter IF I don't move my mouse. But when I move it while scrolling, I get stutter.

Perhaps this has something to do with it?
I noticed you shared some videos from the original post, but I'm struggling to detect stuttering from a large frame time increase. Try replaying the motions again, but run CapFrameX. In the "Overlay" page, ensure the items for Framerate and Frametime are checked, along with the "Graph" checkboxes. If stuttering is linked to the game, Framerate will drop and Frametime will rise. If neither changes much (they're connected), it might be your mouse issue.
