Case shock!!

FriedPC · 10-02-2009, 01:58 PM

Hi,

I think I briefly mentioned this issue in another thread. But I would make a dedicated thread to this issue, because it really starting to confuse me. I am not even sure where this issue belongs so I put it here.

A few weeks ago I started experiencing electrical current running threw my case. It seems to be an on and off thing, just when I think I have resolved it, it comes back even worse. I have torn down the system completely stripping the case and re-built it a few times now and it continues to shock me. I just replaced the motherboard yesterday as well. For a while it seemed the shocking had ceased but it is now back. I also recently purchased a brand new powersupply and that did not resolve the issue either.

System:

GIGABYTE GA-MA790X-DS4
AMD Athlon 64 x2 7750 2.7ghz dual core
2gb PC6400 DDR2 800mhz kingston ram
Corsair 650tx 650w psu
200gb maxtor maxblast
old cd-rw drive

I really do not know what to do now.

I would recommend you have an electrician check your wall socket.

The case should be grounded to the electrical outlet by the 3rd wire in the cord, if the circuit in the house is not grounded correctly it can cause this to happen, if it is grounded correctly and there is a short to the case the PSU or house circuit breaker should be shutting down.

A tester like this will tell you if it wired correctly> http://www.toolking.com/eclipse_400-029.aspx

Ok well nevermind, I spoke too soon. I have left the compaq on for a little while and now it has current running threw the back of the case as well. It has really gotten bad now, when this started it was barely noticeable, now it giving a very decent shock(very unpleasant feeling).

Man..it just keeps getting worse and worse. I have not been able to test the outlet. However I have this other PC(its an older model compaq presario 5410US) but it does not seem to have the shocking issue when plugged into the same outlet.

Certainly sounds like the problem is in the PC and not your household wiring.
Try running the PSU outside the case. That will determine if the PSU is shorting to the case.

Ok, before I try anything I just want to make sure you read the update I made on the previous post. After about a half an hour of leaving the Compaq Presario idle(just sitting at the windows xp login screen) I went ahead and touched the back of the case and it too was shocking the hell out of me. It has a pretty strong current now. Both PC's are having the same issue. My old PSU in MY PC was having this problem. And now while using my new Corsair 650w it is still having this problem.

I assume this points to the wall outlet then? I mean 2 different PC's and 2 different PSU's used in my PC and it is still having this SHOCK EFFECT.

A major question I have about this that I still have not received a response about on any forum is: What kind of damage can be caused by this? What do I have to worry about with this occurring? Shorting of components or lack of power to the components?

Besides paying an electrician to come out and look at the sockets what else can I do(besides using the tester above, I will give that a shot when I get the chance). Is it likely that if this one socket is not grounded properly witch is causing the shocking that the whole rest of house has this problem as well? Can I try to just move to another position in the house and try it there?

Hard to say if the house is not grounded properly or just a few circuits are not, testing is the only way to know, it's possible it's a serious issue like if there is a circuit using the ground wiring as a neutral and the ground is not connected properly it can be dangerous, there are too many variables to know for sure.

Right now you cant take the chance of injury to yourself or someone else. Please get a tech to check the circuitry. [the hot and neutral wires on the proper side of the outlet] A light wouldnt be affected by this issue, but a computer would be.
