Cleaning Procedure for Card Connectors
It is possible for residue to build up on the gold edge connector
pins on some PCI cards, which could cause a variety of symptoms.
If you are having problems with a PCI card, inspect the connector
pins with a magnifying glass. If you find residue, use a pencil
eraser to gently clean the pins.
