I experience a minor shock when I come into contact with any metallic components of my computer.
I've verified it's not an issue with the outlet or surge protector. It seems the problem might be with the power supply unit itself. I'm reaching out for assistance since, earlier, I was testing my PC and accidentally left it powered on, which caused a tingling sensation when I touched it. I promptly moved my hand away and felt anxious afterward. Additionally, both the PSU and surge protector were turned off.
The power supply appears to be touching metal on the enclosure, possibly due to vibration isolation not preventing contact. It seems the concern is about grounding rather than a sudden shock.
I don’t have it connected to anything, and it feels more like a tingling than a shock. I talked to an electrician, and we both noticed the outlet was grounded. I opened my surge protector and confirmed everything was fine. Now I’m confused because I’ve tested other electronics too, and they all seem okay. My own PCs are built by myself, and some prebuilt ones are, but only my PCs aren’t affected.
Outlet and surge protector can be connected to ground, yet this wouldn't matter if the power supply has a bad ground or a short circuit somewhere. This issue occurs not just when the system is turned on or even when the computer is idle. You might attempt grounding the case, but it's more of a temporary solution than a real resolution. Inspect the PSU cables for any damage. It could also be related to a fan or its cable. Any device that draws power will be affected.
I recently talked to my landlord who confirmed there’s no grounding system installed and none of the outlets are connected to a ground. Now I realize anything plugged into those outlets could be hazardous. The most concerning thing is that last night I accidentally touched the rear side of my PC after trying to connect my mouse and keyboard, and it stopped working immediately—no power or signal at all.
Hmm... it seems there’s something off here. Maybe your landlord has an issue or you need a different electrician. Alternatively, you could try testing it yourself. But if there’s no grounding at all, that’s definitely a concern. I understand what you’re saying, but this tends to happen sometimes due to simple mistakes. Kind of like a gun is always loaded—you just can’t be sure.
Both should reach out to a specialist next time! Whether it's grounded or not, the problem seems to be a short circuit in your PC. Likely the motherboard is making contact where it shouldn't—you'll need to inspect the motherboard, standoffs, and cables thoroughly. It might even involve the power supply unit (don't attempt repairs yourself; it's risky).
I spoke with someone local who mentioned the ground wire was linked to neutral—probably because either my landlord made a mistake or the construction team did a poor job. Things are now fixed and everything is properly grounded. I informed my landlord, who apologized for the situation and left me feeling let down about how something like this could happen in Mexico. Regarding the PC, the power supply shut down to protect my components (thank you Corsair for quality PSUs), and I’ve ordered a replacement. Just wanted to thank you for connecting me with a professional and for Vertigo’s help in identifying the issue.
