This is all nonsense. This would all matter if our computers were analog, but the reality is different. You don't have to worry about power quality, the problem will come when the voltage is too low and your PC just won't turn on. Even in spite of all the facts, people have tested perfect system grounding and it hasn't solved their problem.
the voltage can be 100v and your monitor and power supply will still work.
Naturally, the grounding will not work because current still goes through the neutral wire with high resistance.

You're talking nonsense... If the neutral has high resistance, the voltage becomes very low.

if you dont know about this problem, you can keep quiet. i have solved my desync issues after fixing my electrical connection, reinstalling mcbs and putting a dedicated line and mcb for my pc and installing a ups. ( not sure how the ups helped, the biggest fix was improving my electrical situation at my home )

I think I might finally have clarity on this. My local cable operator (who’s also a self-taught electrician) told me that in our area, the neutral at the transformer has been floating for years. He’s had multiple pieces of equipment fail because of it and has already raised complaints, but nothing has been fixed. He even measured ~16V between neutral and earth during the day.
This matches exactly with what I’ve been experiencing since around 2015. Back then I first noticed strange behavior on my PC: things would feel out of sync, delayed, or “floaty.” Over the years I’ve rebuilt my system multiple times — swapped motherboards, RAM, PSU, even tested with different ISPs etc. The pattern never changed: right after a RAM reseat, CMOS reset, or fresh OS install, the system would feel perfect — smooth, responsive, in sync — but after a while it would degrade back into the same inconsistent state.
Now it makes sense. If the supply neutral itself is floating, then no matter what I do at home, my system never has a stable ground reference. That explains why heavy load makes the problem worse, why temporary fixes sometimes help briefly, and why the issue always returns.
In other words, it’s not just my house wiring — the supply itself is already compromised. Unless the transformer neutral is properly grounded, any fix I do locally is only partial at best.
Given that nothing has been fixed for years despite complaints, there’s also a possibility that this could be a deliberate negligence or even a way to inflate bills, though I can’t confirm that. Either way, the unstable supply is the root cause.

What do you/he means by neutral at the transformer floating ?
When someone says neutral floating it means disconnected.

When we say “neutral floating” here, it doesn’t always mean the neutral is completely disconnected. It usually means the neutral at the transformer (or DB) has lost its solid earth reference.
There are two cases:
If neutral is fully open/disconnected, then yes it’s truly floating and very dangerous.
But more often (like in my area), the neutral is still present but weakly bonded to earth at the transformer. That makes it drift a few volts (I’ve seen up to ~16V) above earth depending on load.
So the supply still “works,” but all the equipment is running with a shifting reference, which causes weird behaviour like input lag, floaty mouse, and even hardware damage over time.

I see , I would research for possible malfunctions these will cause then complain electricty company to about them
They wont take seriously our issue for sure , maybe something like " I run a lab in my house and this keep drifting my readings"
But they usually dont give a fck unless some damage to hardware (fear of sue) try to find something like that

Totally true, this has been the exact case around my locality too but it atleast in my city it differs from area to area,
some areas with newer transformers,feeders have better more frequently maintained neutrals.
Even if we do have a low resistance good single point neutral and ground system bonded at our homes, the drifting neutral upstream does dictate the overall impact on sensitive equipments on different times of the day. (Different mouse movement/frame pacing/desync behaviour at different times.)
But still if we invest in a good grounding system installed at our homes like i said in my OP along with the ups's and stuffs things can be on the sunnier side.

Here in Mexico, the standard is to connect the neutral and ground at the base of the meter to maintain a 0 V reference and divert stray currents. Now I suspect the connection between neutral and ground may be poor.
I've already solved all the problems by using LiFePO4 batteries, but I'd like to be able to use my home's mains electricity.
