Question Voltage pen tester indicates current is running trough pc case

[tallchild]

I had some problems with my pc and took it to a repair guy. He said that the problem came from the fact that my pc was running on an ungrounded outlet , but i tested the outlet my computer is connected to and it appears to be fine, but when i put the voltage pen in my pc case it indicates a running current. I have also felt light shocks from my pc in the past, so i believe the reading is correct. What could be causing the problem?

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

You should bring over a certified electrician and have said person go through the wiring in your abode/room. A grounding issue can and will knock out your entire PC.

In a situation like this I would pull every single part out of the case. Check for metal fragments such as left over from threading, check to make sure there isn't a standoff where it doesn't need to be and so forth.

Set the hardware on a table and connect everything that is inside the case there, bread board style and use a meter to see what is leaking the current. IE, your table isn't conductive, so if I hook one lead to a known ground and then use the other lead to probe around on such as where the screws would connect to the mobo, the casing and backplate and such for things like the graphics card, the power supply and so on. Make sure that none of your power supply cables are in a pinch and actually grounding through a wire pass and so on.

DO NOT touch anything that should be actively powered doing this. Only things that should be neutral or specific to ground. If you are not comfortable doing so, please work with the professional to do this check.

You might want to invest in a reliably built PSU, apart from the suggestion I made to get your grounding sorted out in your abode.

yeah i am starting to thing that is the source of the issue, going to ask the repair guy to test the computer with a diferent psu tomorrow to see if the problem remains

Your outlet might indeed be improperly installed.
Not only a missing ground, but the polarity can be foo.
Test with a simple tester like this:

Or, have a qualified electrician test for you since if there is an issue, the electrician will be needed to fix it.

You might also verify that your psu cable is sound.
