							|  | How to install the PCI card |  |  | 
				
					|  | 
				
					| 
						
							|  | 1 |  | Unplug your computer. 
							Power down your computer and then unplug the power 
							cable and all the other cables that are connected to 
							the back. |  |  
							|  |  |  |  
							|  | 2 |  | Open your computer. 
							PCI cards need to be installed inside your Computer's 
							chassis. |  |  
							|  |  |  |  |  |  
							|  | 3 |  | Remove the metal bay 
							cover. Each PCI slot will have a bay 
							associated with it on the back of the computer. When 
							there's nothing installed, the bays are covered by 
							small metal protectors. You can remove one by 
							unscrewing the single screw holding it in place and 
							then lifting it directly out of the case. Set the 
							screw aside. |  |  
							|  |  |  |  |  
							|  |  |  |  |  |  
							|  |  |  |  |  |  
							|  | 4 |  | Gripping the PCI card by 
							the sides. Do not touch the contacts along the 
							bottom, and try to avoid touching any of the 
							circuitry. |  |  
							|  |  |  |  |  
							|  |  |  |   |  |  
							|  |  |  |  |  |  
							|  | 5 |  | Insert the card 
							and press it firmly straight down into the slot. 
							Ensure that the card is level and seated fully in 
							the slot before continuing. note that the X650 PCI 
							card is not required to insert into PCI slot on the 
							motherboard. |  |  
							|  |  |  |  |  
							|  |  |  |  |  |  
							|  | 6 |  | Secure the card. 
							Use the screw that you removed from the metal bay 
							cover and use it to secure the card into the same 
							hole. Tighten the screw firmly but not so tightly 
							that it will strip later. |  |  
							|  |  |  |  |
