Programs which looks for your drivers suck even more.. It's no big deal to download drivers from internet and install them..
Many programs which looks for drivers automatically has a virus in them...
If you have nvidia's video card, go nvidia.com
If you have ATI's video card, go ati.amd.com
CPU drivers you don't need, motherboards chipset drivers are nice plus, but not needed, then there's sound card + Ethernet controller..
It's much safer to find the drivers on your on, instead of using some untrustable program to do it...
