Reduce static electricity in your Case

I always read static electricity is very bad for your PC. However I've never had a PC that didn't gave you a little pinch after opening the case up so I guess it is normal.

In this PC however there is an abnormal high amount of static inside but it only occurs after I plug in the monitor cable on my VGA card.

I've had the electrician ground my wiring today but it is still being highly static in there after I plug in the VGA cable.

Is this normal? I've tried it with different cables, different monitor, onboard vga and my video card. It remains the same, as soon as I plug in the VGA cable my hardware starts to give me little pinches when I touch them.

Is this normal? Is there a way to further reduce the static in my pc by running extra ground wires from the case or isn't this nescescarry?

Yes the monitor and pc are both plugged into the same UPS and the UPS into a grounded circuit.

But isn't it quite normal that you feel some static when you still have your powered on monitor VGA cable plugged into the PC?

Once I disconnect the cable it is all gone.

I'm a bit confused here reading about wrist straps and such and do think it is kinda awkward to get these miniscule pinches touching my harddrives while the VGA is plugged in.

Are you sure it's the PC and not your body? Your body can pick up static electricity when walking over carpet or such, or your clothes rubbing together, or whatever you do when you reach for that monitor cable. Have you tried grounding yourself? Touching something big and metal should help.
