Do you have 3 prong grounded outlets in your house? I know a lot of older homes, built before the 70's still might not have them. If you do, maybe installing a GFCI would be of help, but at the same time, it might keep tripping off, and that's almost as bad...but not quite as bad as getting zapped! If you DON't have grounded outlets, you'd need to contact an electrician for help. Might be a good idea anyway, just to figure out what the heck you have going...
