My computer was plugged in, all switches were turned on (PSU switch, wall plug socket), and I got a tingly shock feeling from my PC case when I touched it(moved my finger across it) whilst I was holding the end of my HDMI cable (I was touching the contacts). This also happens when i touch my case when my iPod charger is plugged into my 360 or TV (360 or TV was turned on). What the hell is this? I really hope it's not a fault in the house wiring. [spoiler]I'm actually being serious for once. And no, I didn't sell it. Check the tags of that other thread for your answer. [/spoiler] EDIT: Yes, I've asked Tom's Hardware. They were no help at all. EDIT: Been speaking with Crantius Colton. He said he's almost certain it's my PSU. Going to get my uncle to bring his computer down to see if his does the same.
