My hunch is either some sort of radiated interference, or a problem with your house wiring.If any more information is needed
It seems like you have just answered your own question. Get a better PSU. Preferably the official RPF power supply.

I'll go out on a limb here and also guess that you aren't using a good surge protector. Get one of those as well (one with line filtering - I like the Tripp Lite brand myself, particularly the Super7).
You haven't put your location in your forum profile, but does that mean you want the power supply delivered to an address in India?I will get a new power supply but cant get the official one coz
they dont ship to where I live. I have tosearch in amazon.in.
The idea from @hawaiianpi to use a surge protector is also worth considering if you are accepting the idea that the problem is being carried via the mains cabling.
This thread reminded me of an old touch switch nightstand lamp that would turn on/off by itself whenever the air conditioner cycled.
