It sounds to me like a heating + loose connection issue - something disconnects when the computer starts heating up, then reconnects again when the computer has reached its operating temperature.
If you have a good hardware guy in your area, see what he can do. If he can't do anything, and this is the computer you use for work, replace it. Your time is too valuable to waste on debugging your tools.

That's actually an issue I currently have with my oven!
When I turn on the grill it'll sometimes short circuit the entire house.
When I flip the electricity back on it'll run without issues.
Took me a while to connect the dots on that one, I usually turn on the oven and then the TV while also microwaving stuff, etc.
Haven't used the grill in months, just using air heating now which works fine

Kind of a long shot, it may have something to do with temperature, but it could be something else entirely...
Besides, they'll want my computer for an entire week, if not longer, which is impossible as it's the only one I have and I still have to work.
Replacing this beast isn't something I'm looking forward to.
Getting something similar will cost me around €3000 (it's the 32 GB RAM that makes it so darn expensive) 
Got this second hand from my previous employer for less than a third of the price.

Issues like that are often from cold solders.
Can often be tracked down using cooling spray and or a heat gun.

Clear out (delete or disable) ALL scheduled tasks in control panel, administrative tools, then restart.
Run AdwCleaner one time from MalwareBytes for good measure.

I am facing weird things latelly too...
my mother in law has randomally no sound at all, not even the green bar when one changes the volume and then it sounds "clink".
It was all working fine, until she started to install messengers for video conferences... she has 5 of them 
Teams, BlueButton and RedConnect due to Work
Zoom due to some distance university lessons she is doing
Skype for some remote "pilates" lessons
M.D.V. 
If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you
Rating helpful answers is nice, but saying thanks can be even nicer.

Something I sometimes experience is that Zoom or Teams changes my default audio output or switches them around.
Normally, I've got my speakers and my headphones and they have different volumes.
It's not at all obvious even when it works as intended.
So anyway, I go into a Teams meeting and my sound is adjusted and suddenly I'm on another output.
Or, I'm on another output while Windows still shows the other one.
Or Teams says I'm using headphones, but I still hear stuff despite not having headphones plugged in, or vice versa, or backwards and inwards out...
It's a bit of a mess sometimes

How long has it been since it had a clean OS install? I ask because I've found that after three or four years we've put so much crap on our PCs that they start to become unstable. Possibly time for a full backup of your data and a complete reinstall of the OS, and I mean complete as in delete the partition table during OS setup.

Less than two years actually.
I'm also not one to install many things.
I've got my regular work stuff and I delete anything I don't need (anymore).
So far, a complete OS install is taking me way more time than an occasional reset, so I'm good, thanks

Usually there's a relation between what's in Task Manager and response.
At startup, the anti-virus will be hogging the CPU. If I see anything I don't like, I disable it (from startup), or delete it all together (like Google Chrome for always doing "something" in the background).

I'd be finished testing my code by now but I am terrible at soldering. 
Somehow, this is a thing that happens.

Isn't that a hardware problem?

That's what I thought too.
I'm trying to test a series of 8x8 LED matrices arranged in different layouts. The trouble is I have two batteries of 8x8 segments, each 4 in a row.
I'd like to connect the two batteries and create a 4x2 battery of 8x8 segments for a total of 32x16 "pixels"
However, in order to do that I need to solder a connector onto one of those batteries of segments so that it can be daisy chained.
Only then will I know if my *software* accurately handles multiple rows of segments. So it's a hardware problem that creates a software issue. - something that crops up with IoT stuff.

I have a lot of challenges with soldering and just ordered this new soldering iron station[^].
I had a really cheap soldering iron (took a long time to heat up and was way too large).
This one has really helped me and I can't believe how much easier things are with it.
You probably already have a nice soldering iron, but if you don't I highly recommend the switch.
Check out the difference in size of my cheapy one (right) vs. my new one (left)[^].
The new one is so much easier to control.
I am an amateur so I didn't even know to know there was a difference. 
Just a thought. Good luck.

I used to use an American Beauty 40W for most fine work. And an _old_ Weller gun ( try to find an old one with copper "tube" ( transformer secondary - the new ones all are Al. and the connections die on you. ) for when you need to slam things.
That said, I highly recommend this https://gokimco.com/products/hakko-fx888d-digital-soldering-station?variant=31349108113460&utm_source=google&utm_medium=cpc&utm_campaign=Google%20Shopping&gclid=EAIaIQobChMI4OHmlsLi8AIVn21vBB3egA_ZEAQYBCABEgLS2vD_BwE[^]
I run it ( by failing memory ) 475 F with Kester lead-free for putting LEDs etc into circuit boards. Nicely made kit.
I've gotten boards from Express PCB Manufacturing Service – ExpressPCB[^]
There are several places that do small short run jobs and supply software.
Their Standard MiniBoardPlus was a good fit for me. Their free software functions, but is very basic and a bit awkward. ( I haven't tried the newer version. )
Worked OK for the simple stuff I did.
The PanaVise is very useful. A wrist - side of hand - pinky rest should help the shake. I use readers so that I'm VERY nearsighted.
You learn to see small color / gloss differences as the solder turns liquid.
Keep your tip clean and shiny, don't leave it idle longer than needed. I usually let it hit temp, wipe it, touch it to solder, start making joints.
Use the sponge, keep it soaked, a small thing of rosin is sometimes useful. Usually, rosin core will supply plenty of flux, but if your tip gets dirty ( oh, I use several, but a small chisel tip seems usually best for component leads ) you may need the extra.
Can't think of much else, wick or a solder sucker can help when you make a mistake.
Have fun,
dave

Shaky hands are my main problem - always had them.

I have shaky hands too and I was watching a guy paint signs the other day and he was using a stabilizing stick for his working hand. Found this video[^], I don't think you need to get as far in depth as this, but maybe it would be something that could help.

Serious reply:
Get the smallest lightest soldering pencil you can find, that you can comfortably hold in a pencil grip (not a saucepan grip). You should be able to steady it all on the heel of your hand or pinkie edge.
Some of the butane gas ones are excellent, once you get the hang of temperature control.
