I have again Theory and somehow i again believe that its related to our Hardware and maybe still Location/Region (but have no idea what it is and still cant believe that it is electricity related)
But Something clearly happens already at Start-up of our Hardware and fucks up with everything like with stability/performance and just windows loading times as example (where some people already able and can notice even this very small changes too and tell that something not alright) and many more weirdness and differences or even random bugs start to happen then after...but our system like runs Unstable from that point on and at the point as soon we Start it...(and online gaming and mostly our network becomes same fuck up experience after for sure 100% but it is where we are all notice it the most ...and this differences)
That why sometimes People noticed that Windows Reinstall (included myself) like randomly helps and that why sometimes they noticed like after Bios and or random Tweaks and many Restarts or Off/On after helped sometimes too (randomly)...but for many this random FUN and Improvement was always for short time and the bad experience returned always again and like again...

like a fucking curse or some magic shit...
And when People moved to other Location with same PC...then there Start-up fixed by itself somehow there and everything start run fine and stable...But for how long this works and stays like in this good stable state ? No one can tell and there no much Information and Update on that and from those Guys who rly moved and become rly fixed...

Many tell like different Story and exprience...
- for some its fixed and like long time...(but are they still feel fixed to this days

)
- for some nothing changed much even in new location and dont noticed difference much at all...
- and for some everything returned again to bad after time/days and become same exact bad experience like it was already in old location....
and then there exist other group of people who claim and tell that you need buy everything completely new and if move to new location...and tell that this 100% fix...but is that rly truth ? again no much proofs or information or anything on that...
But no matter in what and who believe and which direction we go...
Things still so hard fucked up...
With only less Answers and more Questions after...the deeper we go down this Rabbit Hole and everything that related to this...
Many out there and ouside of this...dont even want know and what we all even talk about here...And many think that we are just some Crazy or Shizo...
Edit:
But at the end I believe that it is somehow our Hardwares and something already at Start-up happens which leads to such instability and many other weirdness...what and how ?...I still cant tell and dont know and still dont figure it out here...
2nd Theory...it is still our Internet/Local Network Setup and which matters much too and especially for Online Gaming (where we notice all our Issues the most) and many other things with Internet...But if you already tried everything much possible in this Path and nothing rly bring you a Change or Difference much...
Then now...you know for sure where to Search for Issue and Skill...only 1 Option left.
Thats all what I can tell Guys and from my all Experience too...But many Guys here already tell even much more on this Forum than me and what i could tell...so nothing much new from me and at this End.
I just want only to write again a long Text and all my thoughts with bad English...
But maybe maybe someone will find useful information for himself in this long Text... 
sry.
