Electrient - short?

[qwertyjjj]

Just recently, I would occasionally press the shift/ctl key and I felt a small electric shock running through it (just a little shock, nothing bad, but you can definitely feel it enough to go wtf!). This only happens if I'm pushing hard and I think it's when I touch some part of metal.
I had some other areas on the laptop where the black plastic covering exposed some metal surface and when I touche these I get the same shock.
Also, just lately, I plugged in a line out so I could plug it into my stereo, the end of the line out has the same current running through it as I felt it when I touched the audio LR by mistake.
Any ideas what this could be?
I've covered 2 or 3 of the exposed metal bits by the CD eject button (it's always on worn areas) with tape.

I've got 2 external monitors plugged in, a cooler fan, mouse, external; hard drive.

Dell Inspiron 9300.

It sounds like AC current leaking through the power supply is it an original Dell one? If its a cheap Ebay one its most likely the problem

yes, it is the original dell one. I've read some stuff about the 2 pin being a problem as it's not grounded.
The plug is UK and has 3 pins but maybe the area where the plug joins to the adapter is 2 pin only?

The problem may NOT originate in the computer. It may be coming from the attached peripheral devices, like the audio amp, a monitor, or a fan. Disconnect as many as you can of those and see if the problem disappears, then add them back one at a time.

I'm pretty sure it's the USB monitor.
I reconnected the USB plug from this monitor to the computer but touched the metal part of the USB and got a small shock.
I thught one of the other USBs did this as well but could be imaging it. As you can understand, I'm reluctant to touch the metal parts of all USBs as it hurts a bit
If all the USBs do it, then could it be the actual extension plug? I have an extension with 7 plugs going into it and then that goes into the wall socket.

Any idea what to do or check?
I don;t understand how tieing a metal cable rounf the plastic base of the monitor will help...
