I fought for a year with a similar issue: when getting up from my chair, sometimes my monitor lost the image for a second.

Turned out to be a SecretLab's particular weave accumulating a lot of static and discharging through the chair's feet when getting up because the base then made contact with the frame, generating a proper EMP disrupting the Displayport signal in my cable.

In our offices, I could rub my shoes on the carpet and ALL monitors 7+ would blackout for 1-2 seconds but only if I had my headphones connected.

I used to get mysterious lockups on my personal PC. Turns out I had a habit of touching the case with my leg, and when enough static built up on my chair, the zap from my leg would crash it.

The thing is still going, knock on wood!

A lot of DIY PC cases are almost certainly trash in regards to EMI. One of the reasons for all the scraping interlocking tabs on OEM PCs isn't just that they're cheap to make, but also to ensure a good connection between panels - OEM PCs have to pass EMI tests, DIY PC cases don't.

And that's before considering that most DIY PC cases nowadays, for some unexplainable reason, replace a whole side with transparent acrylic or glass.

It's very explainable: they want their cases to look cool and there's a market for that.

Also annoying if you don't care about blikenlights but do want a large, well made, high airflow case (big fans can spin slowly and be quiet).

They all seem to come with the glass side, PC is on the floor so I mostly live with it but still limits a lot of options.

Same with all the RGB on everything.

Some of us just want a fast computer, we don't really care what it looks like when it's running.

I wanted the same thing, and found the Fractal Meshify series to be a good fit. They can be configured with an opaque metal side panel, and have great airflow.

I have been using 4u server chassis for my last few builds, great airflow, built well, lots of space, and not designed for a 12 year old, they are pretty great.

The only problem is that it really illustrates how desktop class motherboards are 90 degrees out of phase with regards to airflow.

I wonder how the non-DIY gaming PCs are exempt from this, tbh...

Only if the wood is properly earthed!

Seems like you're not the first to find that!

I ran into that one for a while, and I read that newer DP cables’ standard has better shielding to prevent it. I got a newer cable and the issue went away, ymmv

I have the exact same issue with the same chair manufacturer.
