So I have got most of the drivers for XP working fine and things are running great. Only once did XP crash while I was installing the drivers but that was maybe because I installed the wrong one. I was having trouble finding the right driver for my video card, ATI Radeon 4570.
Anyways, to find the drivers I searched google and again came about many posts related to the topic. Tried the drivers one by one, some failed and some didn't. But in the end I came about a post saying that Dell has released xp drivers for Dell Studio 1555! I searched the Dell site and found it to be true. Dell has in fact posted most drivers for xp on its website. So I downloaded them and, as expected, they worked fine. So again, before you go about wandering in googles ocean be sure to check your manufacturer's website first :)
