Standoffs are the plastic or metal pieces that keep the motherboard from touching the part of the case that the motherboard is screwed to. Usually a screw is screwed into the standoffs with the motherboard sandwhiched between the two pieces.

Do an image search for 'pc case standoffs' to confirm your missing them. Your motherboard should not be directly in contact with your case.

You can't connect a MB directly to the metal case without spacers (otherwise known as standoffs) between the bottom of the MB and the metal pan. The spacers (standoffs) can look very different depending upon the case but all serve the same purpose. They will be located wherever there is a screw holding the MB to the pan. Electrically, they ground the MB to the case to help prevent stray currents like you're seeing.

Still weird ; i haven't got a grounded outlet and have no current on my case.

That you grounded it only makes the current leave the system, but where it comes from ?

Don't know, maybe i'm wrong anyway, not an electrician.

Maybe it's just static electricity which could be normal, i really couldn't tell.

On the other hand ; i should feel some sparks now and then if my case had that problem to.

I once bought a second hand pc and the gpu wouldn't work, tried everything but no luck, brought it to the store where they found out that at the back of the pc with all the connectors for internet, usb etc there were some parts of the metal ( clips or something, don't know exactly ) bend inwards and made some kind of short circuit, not so bad to shut the system down but bad enough for the gpu not to work, after fixing that that it worked perfect.

I don't say thats your problem to, but just that it can have lots of reasons and impossible to tell without physically seeing the pc.

Euh . . . i dunno. Not even sure what exact part the shop fixed and how. Maybe just make sure they make no contact or something but pulling out doesn't sound healthy for your pc, they are there for a reason i think.
