Currently I am renting in an old house in Canada, which only has two pronged outlets. I have no clue if there is a grounding wire or romex sheath behind the socket or not; I have an electrician coming soon to take a look at it. The solution is probably going to be to install a GFCI plug. In the event that I cannot have the GFCI plug grounded... is there any way to ground my PC. The house is all linoleum and hardwood, so no carpet; but the winters get pretty dry and last like 8 months (8 months of winter, 4 months of bad sledding). I'm concerned about my computers getting damaged by ESD. I have an old 24" 2006 iMac, and my linux box is mounted in an Antec 302 case Is there anyway I can ground them? An ESD mat? What safety precautions should I take? Touch a door knob before I touch my keyboards? Touch something else metal before I touch my case or open it up. What are my options?
