Why is my USB port giving me a shock?

I've recently noticed that when I plug a USB cable into my PC, the other end gives me a slight shock. It's the same with the USB ports on my computer. As I'm typing this, I think my keyboard might be doing the same thing, but I can't be sure. I suspect this started happening after my power randomly cut out yesterday. Does anyone know why this might be happening and how I can fix it?

It sounds like you might not have a proper earth connection for your power supply. This can definitely cause issues with electrical grounding, leading to shocks when you touch the USB ports. It's worth checking your power supply and making sure everything is grounded correctly.

Could that be something that just happens out of the blue? It sounds serious. Iโ€™d recommend getting a professional to take a look at your wiring if it continues.
