When I touch my IO shield (for example when plugging things in while the computer is on) I get a shock, much like a static shock, however there seems to be a current on the IO shield rather consistantly, as very shortly after a static discharge i'll be able to set it off again.

My main concern here is whether or not this is an issue, does this mean any of my hardware is at risk, or anything like that? The shocks don't bother me personally, it's mainly about hardware damage that I'm afraid of.

This only happends when I touch the I/O shield, not when I touch the case.
I use a european 2-prong plug.

The charge on the chassis is probably due to filters in the power supply that assume the chassis is grounded. With no path to ground, the current through the filters has no where to go but out through you when you touch it.

Shocks that are unpleasant to you can be deadly to your hardware. Signals that are only expected to see a few volts may be exposed to over one hundred and the resulting current could easily fry a sensitive component.

For your safety and that of your machine, you should stop using it and unplug it until you can ground it properly.

wood floor, it doesn't seem to be static charge like I stated in the post, as there is no way I'd be able to generate 2 static charges within seconds of eachother by standing still hanging over my PC to plug things in :/

I don't think I have access to a grounded plug anywhere near my PC, what I'd like to know is if not having it plugged into a grounded plug would have any serious risks to it, if so then I'm gnna have to investigate some way to get it to reach a grounded plug or ground it in some other way.
