My pc shocks me when i touch the case

[Bikola]

Hello
so last mounth i just builed my first PC
today i touched the case and got shocked
can this damage my pc?
how can i fix it ?

 

[Toothless]

Yes it can damage, probably won't. Keep it off the floor, stop scooting your feet on carpet, and make sure your outlet is grounded properly.

my case is on a glass table

What country do you live in?

Take your motherboard out along with psu, gpu, put on non conductive surface, boot your system up outside of the case.

Check to make sure you only have the brass stand offs needed in the case to match up with the motherboard mounting holes.
Remove any extras.


Lightly touch power supply with back of your hand, if it zaps you, you have a short to ground in that psu, replace it.

Thats the culprit.
When I got my glass desk I started getting static shock like crazy.

You can run a humidifier
You can try grounding the table

Or you can create a grounding touch plug like I did,i took a pc power cord, plugged it into the wall, and then shoved a ground plug from another cord into the ground hole of the PC cord, and then I just touch it to discharge , it's connected to the ground via my electrical outlet. cheap/free & simple, plus theres only ground plugs, so you cant electrocute yourself, which is a plus

1 moment, do you get a tingling sensation or a pop? ESD/Static will cause a pop, continuous current causes tingling

It has nothing to do with your pc. You were probably outside, wearing something that easily gathers static electricity, and when you came back it came out when you touched your pc. Next time simply touch a wall when you come back from outside, especially during the winter. It used to be a common practice amongst a few of us tech support guys that drove around and fix peoples pc's, but most forgot about it.

Definitely ensure your case only has the needed brass standoffs for each screw hole in the motherboard.

You may need to create a chassis earth even for psu, or have the outlet checked.

nope its not a ESD even if i touch a wall and touch the metal part of the case i got shocked

i have a m-atx motherboard theres two extra standoffs fo atx motherboard not used should i remove them?

 

[Ferrum Master]

It is a charge build up from the Y capacitator. IEE permits 3.5mA leak. If no ground is present it could charge to usual average 50-80VAC and most people feel it. The glass table is a dielectric so it doesn't get anywhere and while touching it YOU are the best conductor.

He does not have a ground present at home, there is not much he can do as a civilian.

 

[jboydgolfer]

even if i touch a wall and touch the metal part of the case i got shocked

Touching the wall isn't going to ground you unless the wall is conductive. You need to touch the kitchen faucet, or copper pipes, or like that cord I made.

The outlet you posted has three holes so it's a possibility that one of them is ground, maybe the middle one I don't know but you may want to look into it

 

[Splinterdog]

It looks like the middle hole on the outlet he posted is a screw hole, if I'm not mistaken.
Many house where I live (Argentina) don't have the outlet ground connected to an earth, because there's no earth running through the house in the first place.

You need to ground the chassis or the power supply. In CES countries you rarely get the "real" ground, so you can either get slight shocks from ungrounded cases, or slightly bigger shocks if you have a ground line that's not actually connected to the ground.
When we did remodeling in our house, we've added ground but for a year it was not connected to the metal rod outside, so every time there is high inductive load on the mains (washer, freezer etc), then I could get something similar to static when touching electronics with metal chassis.
It's even worse at one of my customer's office. They are located in an old 50s building remodeled for office space. Most of the renters are IT, so they have hundreds of PCs everywhere and no ground. You can actually get shocks and big-ass sparks off PC monitors and laptops.

What you can do, is make a Jerry-rigged ground by running a wire from ground or from PC chassis to water/heating pipes (if made of metal of course, not PVC).

Check under the motherboard, make sure no standoffs are not under the mobo holes.

 

[27MaD]

A bad PSU can cause this , but the chance to damage something is 0.1%.

 

[Ruru]

I remember having that problem and I didn't have a grounded outlet back then.

 

[Frick]

The middle hole is a screw.

Incorrect. This is a grounding problem.

 

[Ruru]

Yep, both correct above.

 

[Vario]

Often its a motherboard tray issue, check to make sure the motherboard is correctly mounted to the standoffs, or isn't mounted directly to the tray or doesn't have anything wedged between board and tray.

i agree with this too. Ive encountered it, not in a personal rig, but a repair job i did. Standoffs incorrectly installed, or not installed at all. Also, I/O shield making contact with the case/plugs iirc.

 

[Vario]

It is not something to be taken lightly, its best to remove the board and check it.

Make sure the board is mounted to the standoffs not directly to the case:

These things are standoffs:

Please let us know the model of the case, model of the board, in fact please just list your full part list for us.

Only if it is touching the motherboard where there isn't a standoff screw point. If they are just sitting there not touching the motherboard at all don't worry about them.

Only thing they could become is rf antennas lol

If you are in a dry climate this is a common everyday ocurrence. The friction between two materials is one of the most common ways to create static electricity. One of the more common experiences is walking around inside and then touching a metal handrail. A ground connection should exist from your PC ccomponents to your PC case from the stanoffs, the case chould also be grounded to the case where you have attached the screws holding the PSI in place. And there should be a ground from your PC to the power cord to the outlet to an earth ground.

When you pick up a static charge, again more common in dry weather, it will seek to discharge thet electric potential to ground. The case serves as a protective "device" here ...the charge will rin from you to case to PSU to cord to outlet to building wiring to ground.

 

[micropage7]

the easiest way to avoid that just using both hands when you holding it
