Mass issue on a PC that I built

Hello,
Since I assembled my PC tower, I've been having a grounding issue that manifests as receiving an electric shock whenever I touch the case or any other metallic part of my computer (effective as an anti-theft system, but I doubt the components like that). By the way, my graphics card just burned out, probably because of this.
Could you please provide me with solutions to fix this problem? Thank you all.

Have you tried removing the hood again and checking all your connections? Also, check if there's any contact between certain components (graphics card) and the case. The same goes for your motherboard.
In this case, you need to plug your PC into a grounded outlet......
I didn't even bother to find out where the insulation fault came from (cheap power supply, I think) and since then, no problem!

To address a bare wire, no, but I had a screw inside that I removed, yet it’s still the same. Any metallic part produces electric shocks, whether it’s the hard drive casing, the internal USB port, or even the processor's cooler, and also throughout the entire case. I don't see where the problem could be coming from??? :o/
At the motherboard level, there is a connection from the spacers to secure it, otherwise there's no contact with the case.
As for my graphics card, I removed it because it burned out; the fan is running but there's no signal anymore.
Regarding my connections, everything seems fine.

I will try to isolate with an insulating plate between my motherboard and my case, as well as at all contact points of my power supply to the case, to see if this improves the problem or not. But could this problem also come from a USB device?
Knowing that another PC in the house (built by a manufacturer) also emits discharges, but much lighter, wouldn't it be possible that this is due to a poor grounding in the house?

Check that there are no unnecessary mounting spacers that would create mass in unplanned locations.
Check the height of the solder joints on the back of the motherboard (some poor finishes can lead to contact with the case).
If you have carpet, avoid placing the case on it, and avoid inserting your hands inside while barefoot or in socks (static electricity).
A good approach would be to disconnect everything and set up an external test to see if it could be the power supply causing these short circuits. Sometimes problems related to the finishing of power supplies can cause this kind of issue (but in this case, two cases seem excessive... but you never know), including in cases of significant heating (expansion of materials).
