Pavilion a6117

hello! i have searched for days at this. i have a pavilion a6117. at first i had windows vista on it but i changed to windows xp, and now i need the drivers for it. i´ve searched at hp.com but they only have the drivers for windows vista. and the big problem is that it doesnt say anything about what parts or models there are in the a6117. ive opened it but i couldnt read anything . the company i bought it from says i should call the hp support but they are putting me on hold for many hours.(and i didnt get any disks or anything when i bought it either.) so im very very very desperate.. please help me!
