I have a newly built system that is extremely static-sensitive at its USB ports - both front and rear - directly or through a USB hub. If I walk across a 10 foot room with a USB disk, as soon as the USB plug gets close to the USB shield in the socket, the computer will do something strange. Variation of strange are USB reset (all ports), complete crash/reboot, various application crashes, crash/restarted display driver.
If I touch the case first, I can often feel a very small static shock, and then the USB drive will connect without incident.
According to an AC tester, the wall socket is correct with working ground.
A DVM shows continuity between the USB socket shields and the ground connection on the AC plug.
Some components in the build are:
MB: Gigabyte Z87X-D3H
PSU: SeaSonic M12II 650
Case: Fractal Design Define R4
Video: MSI GTX 660
I could probably live with this myself, but I'm building a bunch of identical systems for relatives in the midwest where the static is far worse than here so I'm wondering what I might do. Components for those PCs haven't been ordered yet, so I can easily order different parts - if only I knew which part to blame? I suspect the motherboard but I'm really just guessing.
Or should I try to do something else about HOW I assemble these? Currently, the same relatives and I are using systems I built years ago with various Antec enclosures and various Asus and Abit motherboards with no such issues so it appears that a static-insensitive PC is possible. (Or at least it used to be?)
