You will prolly need more than just the video drivers to get everything working properly. Windows will install generic drivers for most components but you really should install drivers for your chipset (motherboard), video, sound, network card, etc. Have a good look at your motherboard and see if you can find a make and model number. If you find make and model # then do a search of the company website for drivers that match your board. You may also find some info by using a program such as Belarc Advisor
