6) After reviewing assigned hardware resources, shut-down Windows.
7) Refer to the documentation for new video card for the specific jumper settings that must be selected before the card is installed.
8) If jumpers are used to set hardware resource values for the new video card:
Example hardware jumpers
NOTE: The factory settings for jumpers on the video card are usually correct and there should be no reason to change any of the jumper settings.
a) Make sure that the hardware resources set by jumpers on the video card are not currently assigned to another device installed in the computer.
b) If the resources set by the jumpers on the video card are assigned to another device, follow the instructions in the manual for the video card to change the resource settings to use an unassigned value for that particular resource.
c) If the resource set by jumpers on the video card cannot be changed to an unassigned value, change device resources of an installed device to free resources that the new video card can use.
9) Turn off power to the computer, and disconnect the power cord from the computer.
10) Remove the computer cover.
11) Locate the video card by tracing the monitor cable connected to the video card.

14) Compare the external connector on the video card to the new video card and make sure the connectors are the same.
VGA/SVGA Video Adapter
NOTE: VGA and SVGA video adapter cards use the same type of external connector. CGA and EGA video cards have different types of external connector. A VGA monitor cannot be connected to a CGA or EGA video card.
15) Compare the card edge connector on the video card to the new video card:
a) If the card edge connectors of both cards are the same, the new video card can be inserted into the same slot that was used by the old video card.
b) If the new video card uses a different type of card edge connector, determine the type of expansion slot that matches the edge connector of the new video card.
NOTE: If the new video card is designed for a expansion slot type that is not found on the motherboard in your computer, the video card cannot be used in your computer.
c) Align the video card with the expansion slot, and then press down firmly until the card seats level in the expansion slot.
Aligning a card with a expansion slot
NOTE: To insert the card into the expansion slot, it may be necessary to insert the card into the slot at a low angle starting at the end of the slot in toward the middle of the motherboard, then gently pressing down until the card is seated level in the slot.
16) Screw the card to the computer and replace the computer cover.
17) Reconnect the power cord to the computer and the monitor cable to the video card.
