PC Case Electrocutes me

[NotAtomic]

Alright,so whenever i turn my pc on,and turn my laptop on too and connect it to charger; whenever i touch a metal part of pc case and metal rim of laptop i get electrocuted.What Could be the fault here? I tried to connect the pc in another room but still the same thing.I tried to connect the pc to a power strip instead of wall outlet still the same thing.What should i do? (Sorry for my english)

Sounds like static

its more likely your environment, 

 

try grounding yourself first(touching radiator) and see how that works

sorry what do you mean by "grounding yourself"

Touching something metal that is grounded so it discharges any static you have built up

Are you sure that your motherboard is not touching the case or a frayed wire in the case?

but that is how my computer electrocuted me could it be that it's not grounded or something

Your wall socket where your electricity comes from likely isn't grounded. This is pretty common for older houses (Pre 1980's).

Did you build your pc yourself? are there standoffs installed? do you have a carpet on your floor?

[NotAtomic]

No i didn't build it myself and yes i do have a carpet in my floor

Is the PC directly in the carpet?

[GenericFanboy]

do you wear socks on your carpet. that causes electric charge. touching a piece of metal discharges that charge= the shock that you feel.

[ManyCoresGuy]

I hope your pc is not directly on the carpet.

what does the carpet have to do with it

[GenericFanboy]

as stated above, carpets can cause static by friction with metal/other fabric.

[NotAtomic]

and by the way sometimes my pc automatically shuts down.Could it be the PSU?

[GenericFanboy]

do you mean standy/sleep mode?

Does the power plug for the laptop charger have a ground pin?

Does it only shock you if the PC and laptop are touched together, or do you also get shocks if you touch just the laptop or just the PC by themselves?

No.i mean the PC automatically shuts down and then when i try to turn the pc on the fans go loud and it does some beeps. but: after i open the case and change rams place it works again.same thing repeats.

It shocks me only when my laptop is charging and when one hand is in the laptop metal rim the other in metal part of PC case

and also i feel the shock in the pc case i just have to touch the laptop while charging too to get shocked

Computer power supplies are designed on purpose to leak a bit of electricity which you shouldn't notice if your computer is plugged in an grounded outlet.  That tiny leak is enough to zap you or to feel it with your hands, but not high enough to hurt you or kill you, the current is very low.

Without this tiny leak of electricity, power supplies would be more noisy in the sense of electric radiation : basically, AM and FM radios, baby monitors, radio remote controls etc etc and the analogue TV reception (back when it was a thing) could be affected, your power supply could "polute" the area around you with electric noise.

 

You need to plug your electronic devices into a grounded outlet and if you use power strips or extension cords, they have to be ground contacts as well. From pc to the outlet, everything must have grounding.

 

The laptop's charger may or may not have a ground wire. In that case, you could try using another charger, if the laptop uses usb type c or some generic DC IN connector.

 

A grounded mains outlet has 3 or more prongs / metal contacts ... two for the AC voltage and one or two contacts for grounding.

 

See https://www.worldstandards.eu/electricity/plugs-and-sockets/ and see Type B and Type E, F, G .. and the other outlets which are grounded

 

In older buildings it's possible to have the outlet with the grounding contacts but not have that ground actually wired to anything.

 

You can check if the outlet is grounded with a multimeter.  Set the meter to AC voltage (set to 750v if you have multiple ranges) then touch two contacts at a time. You should measure some voltage between hot and ground, but nothing (or something like less than a few volts) between ground and neutral. Sometimes hot and neutral are reversed, the important bit is there should be voltage only between one of the hot or neutral AND ground, not between both. If there's no voltage in both cases, you don't have grounding.

 

See video below:

 

 

as for automatic shut down, lack of grounding can affect power supplies and make them randomly shut down. I'd also check that the cpu cooler is properly mounted (not loose, causing cpu to overheat) - use hwInfo to monitor the cpu temperature and other things.

Make sure all connectors are properly plugged in... put your fingers on all connectors and gently push them in and make sure they make good contact.

 

Very rarely, there's computer cases which have a wonky / going bad power button or reset, which would randomly trigger (or switch when temperature inside the house went up and metals inside the switch expanded a tenth of a millimeter or so). Vibrations from feet walking by the case were enough to make the switch activate.

You can try and see if that's the case by removing the switch connector from the motherboard front panel header. You can start the pc just by touching those two pins with a flat head screwdriver for a second or so.
