I've been having this issue for a while now. Any time I attempt to plug something into the front IO ports (headphones, mic, and USB) or even touch them with my hand, it causes my displays to go black like the GPU has shorted out. I have to reboot my system for them to come back up.
At first I thought it was an issue with the front I/O hardware on the case. However, I recently got a new case and the issue is still ongoing. To my knowledge, I have everything wired up properly.
Anyone have any ideas I can try?
