Did u upgrade MSN?? Also how many other services and process do u have running. The lastest MSN does suck a bit. Take it out of startup (forgot if u can or not with the new one). Best not to use XP, better freedom with win2k. Or if you want go Gentoo Linux, all is sweet with that.... :)
Truly the deepest kiss one can feel, and the one most sought after, is the one you will not survive....
