1) Download "DriverDetective Software" , U will get this s/w for free, U hav to do just is go to www.driverdetective.com , Click on its downloads option and then select to download "Driver Detective".

2)Install "DriverDetective" s/w .

3)After Installation finishes Driver Detective will scan ur pc for missing drivers, and on finding the missing
drivers it will automatically download and install the required drivers for ur pc.
