You should not operate most modern computer-type equipment without a three wire grounded outlet. Without some sort of ground, the shunt capacitors in the power line filter (entry module) of some equipment will "float" the chassis to 1/2 the mains voltage. This might be the shock you're feeling!

Thanks, I'll look into it. It's not gonna be an easy task by any means: i'm living in an appartment on the 3rd floor, so there's no crawl space, and surtainly no way to pin a ground rod into the dirt below. But I do know the risks of not having any ground in the house (which is not gonna help when

Heimiko, You need to hire an electrician immediately to ground your outlets - at least the ones where you have devices with metal enclosures plugged in, but preferably all of them. To save money you can alternatively install GFI breakers directly in place of a 2-prong outlet, instead of install

Ethernet is not your problem here - it's transformer coupled so it will not carry a DC voltage or create a ground loop (assuming you're using normal unshielded cable). I did not realize you were trying to solve a real problem here - I thought you were trying to do an "audiophile hack". I am not c

worried about grounding issues. i don't want the ground of my PC hanging on the same ground as my audio. I noticed whenever I touch my PC, and touched my radiator (which has another ground) i get a shock. The only way to get my audio "grounded" is through one of the radiators in the same room, so
