Definitely earthing. Check your house power box.

Or get an electrician to do it.

Earthing problem.
220V is coming through the earthing/ground post which should be 0V.
Contact your electrician ASAP to prevent much more devastating accident in you house.

Its simply because of improper Earthing .

If your spike guard has Earthing indicator you can simply see that there is no earthing.

Just connect your device to a three pin socket where there is proper earthing and you will have your problem solved.

Earthing problem, not a hardware issue. I too face this problem.

I have lived in 3 houses & all had this issue with my computer & no electrician found any earthing issue, present house I asked a through check but electrician team reports all normal but usb shocks even now if I am bare foot otherwise not.

Their checking method is to put on end of multimeter in earth & another in positive the meter does not show any current.
Is this the right method?

^^ Try to see the voltage differnece instead of measuring current.

Do you use one of those multi port circuit boards/surge guard board? If yes do observe the internal /take it to an electrician and verify if the earthing cable is still intact and in contact with all the ground pins on the board.

Cheers!
