Download the software and it will scan your computer for free and identify any hardware drivers that need updating.
Then, if you want, you can pay for the software ($40 I think) and it will automatically download and install the drivers for you.
I tried it and wasn't thrilled to spend the money but in hind sight, it now does save me a lot of time as I can scan my drivers anytime to see if they need updating and download and install whatever I need with only two or three clicks.
Pretty conviennient and I don't have to search any company websites or make sure that I am downloading the right versions.
So far worked for me pretty well and my computer definitely works better too.
Sucks to have to spend the money, but its really conviennient so I think its worth it.
Anyway, you can always just download for a free scan and try and download the drivers somewhere else for free if you want I guess.
