Hi.
There's a stray current flowing from the VGA cable/port of my computer to the PC case.
First, I turned the PSU off with its power button, the current was still there, and then I took the PSU power cable out, still the same,
then one-by-one I took out everything connected to my PC (Pentium IV, 512 MB RAM, FX 5500 GPU), only VGA cable remained, and the current was still there,
finally I took out the VGA cable, then it went away.
I plugged the VGA cable back in, turned the monitor off through its power button; current is there. (PSU cable is unplugged)
I kept the VGA cable in, unplugged the power cable of the monitor; the current was gone.
I first thought, it's all because of my CRT monitor (bad/corrupted caps, etc), so that I tried another monitor (with a different VGA cable), had the same problem.
Whenever the power cable of ANY monitor is connected, the current leaks to whole the PC case (even while the PSU cable is unplugged), no matter what monitor/VGA cable I use.
Replaced the VGA card with a different one, didn't help at all.
So, it's not the VGA card, it's not the PSU, it's not the monitor, it's not the VGA cable.. Well, any idea what's going on?
And if that'd lead any damage to my PC components?
The pictures are attached.

<- No current.
