damaged by static electricity. Be sure that you are properly grounded before
opening your computer case or touching your PCI Express card. StarTech.com
recommends that you wear an anti-static strap when installing any computer
component. If an anti-static strap is unavailable, discharge yourself of any
static electricity build-up by touching a large grounded metal surface (such
as the computer case) for several seconds. Also be careful to handle the PCI
Express card by its edges and not the gold connectors.
