This last bit of work involves uninstalling the software that is specific to your older video card. Examples of this include 3dfx Tools, 3D card overclocking utilities, or any other proprietary software that you installed specifically for your current video card. Unless removed, these utilities will continue to load and some may cause problems with your new video card. It is also recommended that you read the instruction manual included with the new video card, since many require installing the drivers before physically installing the card. Where driver and software installation is concerned, the card's documentation always supercedes any guidelines included here.
One last note for those currently using integrated video solutions such as the Intel 810 and 815 chipset lines. Most new motherboards allow a seamless migration from on-board to dedicated video, but others require a small change to the System BIOS for the new card to be properly recognized. Please consult your motherboard manual for the proper procedure when upgrading from an integrated video solution.
After this process has been completed, it is time to shut the PC down and get ready for the video card installation.
This step will involve unhooking all wires and connectors from the computer and physically opening the case. To open the case, just remove the case screws, or if no screws are present, consult your computer's manual for proper opening instructions. It would also be a good idea to create a working area conducive to the work ahead, with a clean area for the case and plenty of elbow room. Also watch out for static electricity and either wear a grounding wrist strap or use a handy metal device (office chair, filing cabinet, etc.) to discharge static electricity before during and after the installation.
