Seems like ESD. The ESD event makes electrostatic fields, means you don't need to discharge directly into the circuits, a discharge onto the case of the PC will create very strong fields also inside of it. These short term fields can cause components to get a bit out of whack.
- Stevvo 6y agoWouldn't the case act something like a faraday cage, dissipating the fields enough not to cause an issue?
- theandrewbailey 6y agoIf the case isn't electrically grounded/earthed properly, the cat can create a strong enough electric charge in the case and conduct it to other components inside, causing a reboot.
- ivan1783 6y agoIn theory there is no difference between practice and theory, in practice, there is. While your computer case is designed to act as a Faraday cage (for EMI compliance reasons), this is only given when its new +some years old. Many opening/closings of the doors, disassembly/reassembly will wear out the conductive seals and eventually it wont perform as it was originally designed. Also, if the guy cut a big hole in the side to put a window in or something, that ruins the whole Faraday cage concept. Same goes if you put in a fan without a conductive filter closing the opening. ESD is in the GHz range and if you have any slots/holes in the case which are larger than the wavelength of the ESD, the fields will get inside.
