Hi, I am working with a DELL XPS 400 and was wondering if anyone could help me out. Origionally this computer had a pentium d and i am attempting to upgrade to a intel 2 core duo processor...i dont really know if my motherboard supports it or not or how to check if it does. All i know is it is the same socket type. I have attached a file outlining my system.(CPUZ HTML report) Any help would be appriciated thanks. ULTRA_XP.zip
