When I was scouting for a driver, I came across this amazing free program...It will throughly scan your pc and give EVERY possible data on things from installed devices to CPU temperature (!)
It's called Everest Home edition ( yeah , I know I never heard of it either )
As I said this program is free and helped me out a lot:

I believe you can overclock too for all you tweakers out there.
