PC will function everywhere except in my locality

I built my pc in December 2017 and it has worked fine until the last month. We had a power surge in our building resulting in my TV’s PSU getting spoilt. After the surge my pc started behaving weirdly, refusing to turn on at certain times. About 3 and a half weeks its stopped turning on.
What all did I do:

1) Took it to the PC SHOPwhere they plugged it in and it worked with no hiccups.

2) Took it back home, worked for one day and it stopped working the next day.

3) Took it to my neighbor’s house; didn’t work.

4) Took it to my grandmother’s house in the same locality (400m away); didn’t work.

5) Took my PSU and my PC (without my PSU) back to the PC SHOP; PSU worked on other boards and after connecting it to my PC, the PC also worked.

6) Took the PC to my friend’s house who lives in another part of the city, disassembled the pc and reassembled it and tried it there; worked. Was told by the PC SHOP that it must be an electric/ voltage problem in my locality.

7) Called an electrician home who tested my sockets with a 100v bulb and he found no issue.

I’m thinking of giving my PSU for an RMA but am worried that they will check my PSU, say that it’s perfectly functional and return it.
What steps should I take?

Something odd here.

You write about assembling and more but why isn't the PC just picked up and moved intact?

Parting note: Our rule about the Ryzens. The BIOS shall be current.

do you live near any high power lines?

They can interfere a lot with home electronics.

Here's an example of how much influence they can have just through the electrical emissions which emanate from them. They can also interfere with the "stepped down" power lines delivered to homes near them. You can't see that using a "bulb" but can with an oscilloscope, but how many have one of those sitting around?
