Can you check if the metal screws you used do not contact any pins or copper?
Also verify that they didn't damage the pcb, when screwing them in.

Are you using battery power?

It looks to me like you might be getting power supply noise on your DC voltages.
This is a common problem with medical devices, which is why they have very stringent noise filter requirements.

You can also get this type of noise from lights.
