Hope one of these works. I have ran multicores in the past and had issue with xp, cause of windows live update crarp that worked on on cpu and not anothe, one of the othe was to eliminate the live uped entirly using either or both methods (cant remember). Now I did the i3 upgrade and had to reduce to the 2 core angle which doesnt recognise my graphics cards max potiental. It only reads as if Im usin my onboard graphics. So hope this was some help, dont give up.
