I am not sure what values you mean so if you can specifi them ?

You need a Multimeter (also known as AVOmeter) to check your grounding quality and stability. It can be a simple model, you don't need to buy an expensive one. After you get a multimeter what you want to do is to take certain measurements on the outlet you use for your pc, you can also test your extension cord afterwards as well;

First: Check if your voltage is stable by inserting one of your probes to hot and other one to neutral. If the value is around your country standard ±5% it is stable, the value should not be jumpy, if it is jumpy your probes are not still/you are moving your probes around.

Second: Leave the first probe in hot and move the second probe which was in neutral to grounding and check if your readings are the same as the first step, they should be roughly the same.

Third: Move the first probe from hot to neutral and leave the second probe in ground and please share your values for all the steps, especially the third step with your country standard voltage.

P.S. While using a multimeter make sure that the multimeter is set to a higher value than your country standard, e.g. your country has a standard of 230 volts, then make sure that your multimeter is set to a higher value and not 200 etc. you can set to lower values for a more precise reading for the third step after you make sure that you first read the value while keeping the multimeter on a higher setting, in case your grounding is connected to neutral, which should not be the case but some houses have such issues. If you drop the multimeter reading setting to below the voltage it receives you will blow your fuse/damage the multimeter.

Hot - Neutral 240-247V +-
Hot- Ground - same values as above
Neutral - Ground - 0V never change

Multimeter : UNI-T UT181A

In some countries with old type electrical wiring it is necessary to bond neutral to ground at socket if you want grounding done (there are only two wires coming to the socket). It is best to have 3 wires, but not everyone wants to do full apartment renovation.

Anyway, ground or no ground doesn't make lasting difference. I never had ground in my apartment when everything was working good. Then this issue came.
I was also wondering if some changes in electric wiring for other apartments in apartment block would affect anything.
Let's say 30% of people in apartment block rewire their apartment to have 3 wires.
Rest of them are still having 2 wire setup.
Would that affect anything?

However, there are people who have this issue in modern apartments where everyone should have 3 wires.
