Are motherboards THIS sensitive?

[Matchptt]

 

Hi everybody, I wrote a few months ago, my PC stuck after a heavy object had fallen by the house, I had no problems until a few weeks ago when the power bank fell on the side of the house motherboard, And I found that my computer was very sensitive to the bumps. Every time I flicked my fingers on the pc panel, the mouse stopped responding, the audio blocked on the last fraction of a second loop, and I was forced to reset the system.

After checking psu, gpu, cables, cpu, ram, etc, I brought the computer to the store, and told me that the motherboard was the problem, specifically a usb path was shorting.
So problem solved right? not really...
I bought another pc, new cpu, motherboard, gpu, new ram, new hard drive, new psu, even new case and sata cables, I tried to hit the new PC case on the same spot where my old one freezed ... and it freezed too ... I can not understand how unlucky I can be to have two completely different computers with the same problem..
Or is some security technology for hard drives that I do not know?
I'm 100% sure that both PCs are assembled correctly and that no component is malfunctioning, except for the motherboards ...
A motherboard is asus and the other is asrock. For the rest, both computers work properly ...

can anyone help me to better understand this situation? Sorry for the bad english

Hmm, are you using the same wall outlet and/or surge protector?  I would try another outlet at the very least. It definitely sounds like dodgy electricals IMO.

nope, they are in completely separate rooms, 
And since the problem persisted in the computer shop for the firt pc, i guess i cant blame outlets or my home ...
