PCI Express Cards can be severely damaged by static electricity. Ensure that you
are properly grounded before you open your Computer Case or touch the PCI
Express Card. You should wear an Anti-Static Strap when you install any computer
component. If an Anti-Static Strap isn’t available, discharge any built-up static
electricity by touching a large Grounded Metal Surface for several seconds. Only
handle the PCI Express Card by its edges and don’t touch the gold connectors.
