Electrostatic discharges from chairs can interfere with USB and display signals:
"Surprisingly, we have also seen this issue connected to gas lift office chairs. When people stand or sit on gas lift chairs, they can generate an EMI spike which is picked up on the video cables, causing a loss of sync. If you have users complaining about displays randomly flickering it could actually be connected to people sitting on gas lift chairs. Again swapping video cables, especially for ones with magnetic ferrite ring on the cable, can eliminate this problem."

KaptainKanasta, if you're out there, I know I speak for others who would love to hear if the chair was indeed the culprit. Though if it wasnt the chair and was indeed a malevolent spirit, I fear the worst.
