Installation
WARNING! PCI Express cards, like all computer equipment, can be severely 
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.
