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.

pins with a magnifying glass. If you find residue, use a pencil 
eraser to gently clean the pins. Remember, never handle the PCI 
cards by the gold connectors.
