The I/O shield develops static charge upon contact.
It seems there might be some electrical activity happening inside your PC when you power it on. The current you observed through the I/O shield and the metal part of your keyboard could indicate a loose connection, a faulty component, or even a grounding issue. Checking for proper wiring and ensuring all connections are secure might help clarify what’s going on.
Your wall outlets with three connection points are grounded, while those with only two points are not.
