That is consistent with metallic debris in a DB15 module connector. It might still be there, waiting to cause trouble again at some inopportune moment. Take the time to remove the modules and inspect the connectors using a very bright light and perhaps a magnifier. Make sure nothing is hiding in there ready to short any of the connector pins.
