I have 'earthing / grounding' problem at my home. That is, when connected to the power outlet through the UPS, my CPU cabinet gets 'body-current'. Touch it and U get a electric shock. Just how much damage can it cause to my computer?

Grounding issue

A lot. You better do something about that, e.g. grounding the box. Run a wire to the closest waterline - if that is in metal. Else run a copper pipe into the ground in front of the window and a wire from there. Make sure there is good contact everywhere including the chassis of your PC.
@whs,you were real close my friend.There should be proper sized wiring from a copper grounding rod AND a metal water pipe (cold water side) to the main electrical panel.Wire size depends on the amperage of the main electrical service.My thoughts are a faulty UPS,I'd just plug the computer directly into the wall outlet and if good,have the UPS checked out.
Another way would be to pound a copper ground rod in the same room as the machine.And whatever the size of the wire going to the wall receptacle,I'd go a size larger using a ground clamp on the rod and then bond it to the computer chassis.@whs,you are welcome,for you are such a very kind person.You proved your patience on an earlier thread with one of our future geeks.:p
Hello!
I'm new to this forum, but an electronics tech of 44 years, so grounding is nothing new to me.
A big problem I see often is that people will NOT plug their entire computer system into the same outlet. That's a absolute MUST!
Everything that touches your computer tower, electrically, should be plugged into the UPS and it should be plugged into a three pronged wall outlet.
That will keep everything on your system at the same polarity and grounding potential.
If the computer system is properly grounded and you have static on your body, like from a wool rug, the static will find its way to ground thru your computer. Do something about your own static in that case.
Where I live, here in Florida, static is NO problem, but when I lived up North, static was a huge problem in the winter.
But, static or no static, it's still advisable to keep your whole system plugged into a common circuit.
Cheers Mates!
