Can someone teach me how to install a new video card? It's going to be a Diamond HD 4850 512MB on an Intel X38 motherboard. Correct me if I'm wrong. 1. Uninstall the old graphics card drivers. 2. Shut off the computer. 3. Replace the graphics card. 4. Start the computer and then insert the drivers CD. 5. After installing the drivers, check online for the latest drivers. Also, what do I do if my computer doesn't automatically detect the new graphics card?
