I worked the Dell forums for over 10 years (I'm still listed as one of the "rockstars") The "standard" install procedure we gave to all users.
1 Install Windows, 2 Install Dell Laptop (or Desktop as applicable) Support Software, 3 Install Intel motherboard chipset drivers (and other chipset drivers as applicable), 4. Install device drivers including Video, Sound, Ethernet/Wi-Fi, etc.
I would download all the drivers from the Dell downloads for your specific VOSTRO model. Burn them to a disc or a USB flash drive so you will have all the needed drivers for the "clean" install.
