Hi, I reformatted my Dell Inspiron 1440 laptop yesterday and did a clean install of the Vista Home Basic 64 bit OS. Next, I need to install the drivers, but I'm not sure which ones are already installed and which ones I need to install off the Drivers and Utilities CD or the Dell website. When I put in the Drivers and Utilities CD, it showed a list of drivers on the CD and tickmarks next to a few drivers which meant that it scanned these devices existed on my laptop. So I installed the three drivers which showed the tickmarks - ATI graphics, WLAN, and Bluetooth. The rest of the drivers don't have tickmarks on them. So I'm not sure if they match my laptop or not, and whether I should install or not. I mean, my little manual says I have IDT 92HD81 audio, but on the CD and website (under my service tag) it gives the number as IDT 92HD71B. Can I install this even though the number is different? Second question - do I need to install chipset, network, camera, touchpad, and other drivers too? How do I know what to install and whats already installed? Please help, I'm really confused.
