As the title says, when I touch my case, I get a little shock. Nothing serious but it is quite annoying. What can I do? What can the cause this? Nothing happens to the computer or something, it's just annoying.
Also, when I touch the side of the case with my feet, it feels like it is vibrating. I noticed that when I touch with one foot the case and with the other foot a metal object, I feel the vibration in both of my feet :D
its not grounded properly

get a new psu
hmm signs of a current flowing through the case
check all the wires
even in the PSU
either that or ESD
Accept that you got a free foot massager and move on.
Either your PSU has Schizophrenia or that shit's haunted.

Pre-built or custom? If its a pre-built, contact the manufacturer, its a build defect.
If its a custom, make sure the motherboard is correctly mounted, and that everything is clean and dust free.
It's custom, dust-free and I am going to check the cables and everything else inside the case right now. Well I do know one thing in the case, in the PCI slots I've got a graphicscard and I don't know, some sort of network card or something, just below the gpu.
Anyway, when I start my pc up, the fan of my graphics card touches the upper part of the networkcardthingy. But only for a second, after that everything goes normal and it doesn't touch the network card. That's only problem I know but I don't think that can cause it.
I've also read something about earthed sockets or something and that 'un-earthed' ones can cause problems. Now would anyone mind explaining me the difference since I don't understand a shit of what it means?
If it feels like your feet are vibrating, that's AC current. Likely the PSU is shorted out or grounded wrong. If you have a volt meter, touch one prong to the case and stick the other prong in the ground of an electrical socket to see how much voltage is flowing.
I had this problem on one of my servers and it turned out to be a bad power cable, so you may want to check that too.

AC current doesn't carry enough magnetic force to cause vibrations. It's probably the fans or something else. Not to mention that the power supply converts the AC to DC current.
Make sure you ground yourself to the computer before you touch anything when you open it up.

No, if it feels like your feet are [i]burning[/i] that's AC current

The "vibration" the OP is describing is clearly being electrocuted, not the case vibrating. When you have AC voltage passing through your body, it makes your muscles rapidly expand and contract, which can be described as feeling vibration.

Incorrect, it depends on the voltage level involved. Improper grounds don't give you a direct dose of wall current, often only about half or less depending on how improper the wiring is. Anything below 60v AC is usually just felt as the vibration from the expanding / contracting muscles the OP described.
Hold a small light bulb and see what happens.
This happens to me too. Scary shit.
why does everyone think its the computer, this faggoty ass gook is probably just sliding his feet with socks on all over his carpet

Best laugh I've had in awhile.
And to think I used to consider you a douche.

What do you understand with 'improper wiring/grounding'? What is 'improper' for you?
[QUOTE=BrQ;18490509]What do you understand with 'improper wiring/grounding'? What is 'improper' for you?[/QUOTE]
Improper wiring is wiring that passes current through the case.
No wonder you haven't fixed it yet...
[QUOTE=Maccabee;18481237]Make sure you ground yourself to the computer before you touch anything when you open it up.[/QUOTE]
thats not such a good idea in his case

If an electrician is lazy, they can split the neutral leg in the breaker box instead of giving each breaker its own neutral, which can start back feeding voltage into the circuit. Neutral can also somehow get shorted or crossed with ground, and depending on how much wire is contacting, depends on the shock you get out of it.
Other things like improperly wired two way and three way switches can also cause similar situations where voltage is fed into the wrong wires. The appliance attached to the switches will still work, it will just cause other problems if anything else is on the same circuit.

Where do you live? I'm in chilly northern Minnesota, and it gets really staticy this time of year. Every time I touch my computer case I shock it, and if I forget I shock my keyboard and it goes funky.

Like I've been saying, it's not static, it's mains voltage.
try licking the case while grounding yourself.
[QUOTE=FlexMiester;18497148]try licking the case while grounding yourself.[/QUOTE]
Naah, put the case in a metal tub while standing on a metal grounded mat and take a whizz on the case.
Sounds like your computer isn't grounded.
Used to happen to me too, with everything for a matter of fact, due to my house not having a ground connection. :downs:
Well, ever since I discovered it's actually very relaxing for my feet, I just keep it this way.
Can it cause any harm? To me or the computer?

Everybody is shitting their pants over some static while installing, so I'd be a bit worried if mains power is leaking to the case.
Well like we have said it could just be you, and no a problem with the computer. A shock is a result of two items with very different static charges touching. so you could have the static, or the computer. But it really doesnt matter if you just shock the case. just dont touch a component. That's what the case is for.
Also, being grounded to your computer just means that you have the same voltage running through you. So you are actually grounding yourself when you touch the computer and get shocked.

So there's absolutley no problem? Well, I'm pretty sure it's the pc. I've asked various people to touch the case and they all said it gave them a little shock. Just a little one, it's like you just touched something sharp like a piece of glass but it doesn't bleed. The good thing is that it gives awesome foot massages (when wearing socks, never tried it on bare foots)
edit
I just changed the socket to something what they call an earthed socket. Now I noticed something, when I touch my case, nothing happens. When I touch my case (with my hands) AND I am touching a metal object, I do get a little shock.
Ok, that is a sign of improvement. that means that the voltage in the metal object may be different than that of the computer. If you are touching the object and get a shock many times in a row that is a cause for concern cause it means there is voltage charging in one of the things. wether it be static on you, the computer, or the object, but as long as you dont touch the inside of your computer, you cant harm it.
