Question New build shuts off due to static electricity and I cannot figure out the cause

[redpotatoe]

I recently built a fractal terra. Other than an issue with helldivers shutting the pc off if clock speed is set to default (once I lower it to 2500mz from 2900 it stays stable) it has ran fine. Today I noticed an issue if I have any slight bit of a static charge and I touch my case the moniter shuts off. Fans stay spinning and lights remain on. Also if when it crashes I leave it on but insert the hdmi into the motherboard directly it comes back on. Gpu still won't give picture until reboot but the motheboard will. At the same time if I touch it with a static shock when it's plugged into motherboard to begin with it won't crash, it will flicker but it stays on.

I tried different outlets and it did not work. At first when I moved to an actual grounded outlet it seemed to fix it, at first. Then after a few times testing it it would shut off aswell and then would consistently every time after. I removed the psu from the case and touched the case without the psu touching the case anywhere and still crashed so I don't think it's the psu. I Swapped a backup gpu into it and it seemed to go away at first. But now it has been doing similar things. If I have enough of a static shock it may make the screen flicker, go black for second, feeze the pc or make the app (amd adrenalin specifily) flicker. After touching it after rubbing my feet on the carpet multiple times over and over it finally did have the screen go black once with the new gpu, but only once whereas the previous gpu would do it every single time no matter how little shock. Any ideas on what to do? I have spent so many hours getting this thing running right and it's very discouraging at this point

your motherboard? If so, what BIOS version are you on? As for the build, have you tried breadboarding it to see if lack of airflow across the VRM is causing the issue?

You might want to relocate to another wall outlet. If that doesn't alleviate the issue, you should call in a certified electrician and scope out the wiring in your abode to see if your grounding has been compromised.

Yes, that's indicative of you having a grounding issue.

Yes that's the correct board, I have 3.10. I tried in an outlast that comes directy from the panel that was only installed a few years ago and it still caused the issue. By breadboardinf do you mean taking the parts out of the case? I took the psu out and tried it that way and touching the psu when separate from case it would not short. If psu is screwed into case and I touch psu then it shorts.

I also have another pc in the house that has a more powerful gpu and cpu and that pc in the same outlet does not cause an issue, if that matters at all

Having everything on your motherboard box and your bench, not inside the case.
