StarTech.com recommends that you wear an anti-static strap when
installing any computer component. If an anti-static strap is unavail-
able, 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 card by its edges and not the
gold connectors.
