contact a member by the name of Phoenix86. he wrote a tutorial that was on another site, but that other site is currently down. his tutorial works like a dream because there is a tool to do this and i think it is on the xp disc. i wish that the mods would put Phoexnix86's tutorial here and sticky it, i did a motherboard swapout and fix in less than 1h 30mins and had full functionality of all my programs with no problems whatsoever, and this xp install is going on 1.5yrs old even though i have changed m/b, gpu, hdds, ram, cpu, etc.
