I'm having the same problem, except it's crashing my dang PC. Actually, it's only crashing the GPU, but that's pretty indistinguishable from the whole PC crashing in practice.

Now I'm wondering if I should ground my chair to the shelf my PC is sitting on.

As pretty obvious evidence this is static related, it only happens in the winter.

I've had the same problem for a couple years - specifically the GPU crashing. Had a very hard time isolating the issue - seems like a mix of static + the EMI spike OP talks about (it happens most reliably when I stand up quickly from my desk chair).

My guess is that, like OP, we're both getting interference in the our DP connections, and that that interference is in our cases causing the GPUs to crash.

Haven't had a chance to try ferrite cores yet but that was going to be my first test.

Curious what system specs you have in case we have overlap in anything that could isolate the issue. Mine: https://pcpartpicker.com/list/Xpdb8Z

Mine: https://pcpartpicker.com/list/Kw7wh9 It was happening more often when I had a Sapphire NITRO+ RX VEGA64, but the 6950 XT isn't immune.

other things not encapsulated in the parts list: My PC sits on the bottom shelf of a foodservice-style wire shelving rack. My motherboard's I/O shield is integrated and wasn't a perfect fit into the case.

The DP cable is, probably, in-spec. I usually buy Cable Matters or BlueRigger.

I do wonder if ferrite cores would help.

edit: The only similarity I notice in our builds is lower-end ASRock b650 motherboards.
