Always "on the ball", whether you currently happen to need to download a video driver or a sound card driver, it just "knows" exactly what you need
. Here's another benefit: should you have a computer that is not hooked up to the net, you will have to keep that computer's drivers up-to-date as well. Can a single program really have the capability to prevent all your driver(s) hassles? In all probability, no, but i strongly advise you to put it to the test when you can. Most of us like to increase our computer's arsenal of hardware and software quite frequently, thus it must be our routine to keep them maintained properly. No matter which way you go, it is highly recommended that you scan and detect all your problematic/missing drivers; your pc will thank you for it - by performing much better!
