Is the fan working noisy?
I have run many HP i5-8600/i7-9700 DM computers. it's unlikely an issue on CPU paste. possible issues as you have got it over three years.

my HP i5-8600 was noisy when heavily loading (processing graphics, streaming, , ,) and getting hot. it's...
Try a WIFI tool, LocalSend, a free, open-source app. portable.

I don't use USB cable these days. If a wifi device, just use its wifi feature.
also monitor if CPU overheating.
Is this a home-built computer. then is CPU glue applied well?
to isolate it's NOT a software issue, backup OS and data, then do a clean-install, either W10 or W11, no matter. to see if computer runs stable. If still sees instability, then must be a hardware...
It's so true.
Their customized ESP is in uncommon size. And NOT user-friendly to handle with.
I run several theirs. While re-formatted and did clean-install OS. HP DM computer has more ports on USB3 and graphics. Which are useful in my work.
Dell is inexpensive than HP. Plastic-like. But good...
Typically, a hardware issue.
you have to isolate PSU, RAM, SSD, Graphics, , , one by one.
If you run two sticks RAM, test them one stick by one to isolate. For Graphics, test built-in 1st, then external , , ,
what's the RAM and storage size?
If limited by RAM and Storage, you could try this solution.

my storage is WDC SN770 1TB NVMe SSD. a similar but slower one.
the computer runs out of SSD slot. hence my solution was using NVMe adapter card on PCIe slot. it run fine. even on a 15-yrs old computer, it had no problem. in reality, I often move it from one PCIe slot to another computer's...
25H2 has MSFT SID issue. a buggy release. I tried but gave up. (as its image couldn't transfer to other PC)

You better NOT run clean-install on the computer.
You could have two choices
Restore an image of other PC's W11 on to this computer than clean-install. (Please read my post of Lenovo 2 GB)
Make your own SD11 (search mydigitallife) install media. A better way.
For choice#1, my OS size was...
4 GB should be enough.
I run W11 on a Lenovo 2 GB so far.

I run into a similar problem. saved photos (*.jpg) from my phone then some of them couldn't open using Windows photo viewer. got error message.
Later, I tried Paint.exe. paint can open those photos Windows photo viewer couldn't.
I do.
my NAS runs mix of SSDs and HDDs. often big size files move (images added/removed). at that time, manually defragment is my best choice.
my main computers have SSD only. every time after restoring image, I do manually trimming as I see "Never , , ," when image done.
There is a significant difference in your down/up load speed. so your ISP must be a cable company. Cable ISP upload speed often much lower than download speed.
In contrast, @Bree must be using a fiber company. her down/up load speed nearly identical.
Internet speed specs is payment-related...
