I know there are a lot of posts and questions regarding electrostatic discharge (ESD) when building a PC but couldn’t find a specific answer for the case I’m encountering.
Today I built a new PC(my first), had bought a strap to keep grounded all was good,
Until I had to lift the board and get my eyes close to it (to inspect a standoff screw) at which point I heard a very soft clicking noise.
It was my hair that came in contact with the back (underside) of the motherboard.
Now to be clear I don’t have abnormally long hair, and am not prone to frequent zaps, but it is dry cold winter so…
Couldn’t tell if there was an electric discharge or simply a single hair that got hooked to one of the soldering and snapped when i backed away.
My understanding was that the strap would keep all ESD safe, but after some light testing with an old small liquid crystal display i realized that whatever static i had in my hair was independent from rest of body and not discharged.
I have not had a chance yet to test the build as it’s missing some components (mainly PSU). So unclear if it is damaged.
At the time of “noise” the only components installed were NVMe SSD and CPU (with cooler). So my questions are:
- What components are prone to damage by ESD ? Is a CPU vulnerable remotely (meaning via the board getting shocked?)
- Should I be worried for the board? The motherboard in question is an from Asus X570.
- In your opinion would I be worth attempting to replace with a new?
- Do modern boards have ESD protection all around of is that a myth?
- And ultimately how to mitigate this risk aside from wearing a full hair cover?
Thanks for reading and offering some insight, this might seem like a lot for so little; but when you spend large amount of money and decide to do it yourself, can’t help but freak over what you could have wrong.
