What are your “plugging into the PC”? This is a tower/desktop right? If you get the shock from touching the case then you are probably missing your ground connection.
Thank you for your reply, it is indeed a “tower/desktop”, I get the shock if I plug in a flashdrive with metal parts or a cell phone into the USB but also when I plug in internet cables or indeed any cables into the back of the machine, it wouldn’t kill me but it’s damned unpleasant nonetheless.
I bought a rubber shower mat and put it under the machine as someone said something about earthing it but it really didn’t make any difference.
An additional piece of information is that I live in SE Asia so I don’t know if they have some sort of different electricity system here.
Forgive me if I sound like a bit of an imbecile but working out how to avoid being electrocuted was not part of my computer training, I’m not a geek but I’m not completely stupid and I would welcome any advice.
