Loud vibration on the PC case and connected to the peripherals
Hello everyone, I’m facing an issue with my PC. It gives me a shock when I touch my case, even though there’s no static. This occurs every time I power it on, and it seems like everything connected to the PC—especially metal accessories—also gets shocked. I have a 500W PSU, but I’m not sure why this happens.
Possible reasons include:
- Incorrect grounding of the power supply to the wall, allowing charge buildup that affects the motherboard, power supply, and case due to shared ground points.
- Minor static electricity interference.
- A PC component is connecting to ground unintentionally, possibly through a USB device or internal header, causing a short at low wattage levels.
The issue might not be the grounding itself. I’m connecting to a grounded outlet, yet things like a hairdryer still shock me. Whenever I touch the back of the case it happens—never before. I’ll double-check but I’ve already inspected the inside and everything looks secure.
