There's a stray current flowing from my monitor through the VGA cable to the PC. Is this safe?

I have two monitors in my machine. One is an old LCS samsung monitor. Recently, I started to hear a small hum in my speakers (subwoofer) and replaced them. The new one also got the issues then I found our that its a grounding issue. I unplugged the PC's power chord. The monitor is still switched on. When I checked, there's current in the earth pin (ground pin). When I unplug the monitor, there's no current and the speaker is normal. Now, I have moved that monitor to my dad's machine and took his monitor.

My question is, is it a big issues? The house's earthing system is working and its grounding the current. I won't feel it if I touch the machine like in many other cases.

But still, is it good to keep that monitor attached to my machine?
Can it harm the computer?
What should I do?
