PC has suddenly become extremely slow

[kokotas]

I came back from work today and I was excited to plug in my freshly serviced cx48 oled (changed panel) only to find that my pc was being extremely sluggish. Even opening a folder is taking forever... So I ran a quick userbenchmark to get a general idea of what's happening and this is what I bumped into

I already tried:
1)Uninstalling/reinstalling chipset/sata/gpu/nvme drivers.

2) Safe mode

3)Updating bios/optimized defaults

4)Unplugging all devices

5)Unplugging UPS and plugging power supply directly to wall

So before I go about unplugging internal components or re-installing windows, does anyone have any idea of what might have happened here?

There is no sign of disk usage while on idle. I think there is an issue with the pcie lanes. Either the mobo itself or something in the gpu has crapped out and causing problems.

First I will reinstall windows to rule that out, but I'm not very hopeful. It will be a fun new years eve lol

Good news. Fresh windows install and everything is back to normal which begs the question... What could have caused such a problem rendering the system almost unusable? I guess the lesson learned is to make system restore points which I never do.
