I currently have a custom built PC i bought back in 2016. Recently this past week, when i was charging my phone via the usb port on my computer case (NZXT H440) i could feel a buzzing sensation whenever i touch the home button of my iphone which was near the port. I decided to plug it out of my phone and touch the cable end directly with my hands and i could feel the buzzing sensation. I tried it on another port in my room and it doesn't seem to occur so i suspect it might be something wrong with my computer. I also tried another usb cable which was used to charge a portable USB lamp and i got a greater electric shock from it when i touched the cable connected to my computer usb port.
Can anyone pin point me the issue if it could be because i'm not grounded, or the motherboard problem or even the power supply? Thanks in advance!
TLDR, anything connected to the usb port of my computer gives out a small electric shock and i do not know what the issue it.
