I posted this here instead of Linux forum because it seems like a hardware thing, and it's only affecting the GPU....
I am experiencing the strangest issue.... I would notice that sometimes, when I plugged in a USB device, my screens would go black and I couldn't get them back. I noticed that even though the monitors weren't getting any signal, my PC was still running. I could still SSH into it, and things like YouTube or spotify were still running. I could even play/pause/skip with my keyboard still.
I checked my logs, and I saw this:
Then I started noticing that it would happen if I happened to brush against my computer case and get a static shock. I realized that when I was plugging in USB devices, I must be getting a shock, too. I've since confirmed this to a reasonable extent by making sure to touch something metal that's NOT the PC when I plug in a USB device. I haven't had a problem when I remember to do that.
So I can try to make sure I'm grounded, and I have a small humidifier in the room to try and keep the RH up a little, but the problem remains, and it's concerning to me. My house is a new build, only four years old, and I have my PC plugged into a properly grounded surge protector. I feel like a static shock, especially when it's just to the case, and not the USB port or something, shouldn't be causing my GPU to drop out.
One other note is that I've really only noticed this since I changed from an RTX 4070 TS to a RX 9700 XT a few months ago. It might just be coincidence, but the timing fits.

Sapphire Nitro+ RX 9070 XT

EVGA Supernova 1000W P3, 80 Plus Platinum
Thermaltake Core P3 ATX case
