so i bought winxp home sp2....OEM. and for some reason, it installs, then before it gets to the desktop...it freezes. i was on a 30 day trial, i reformatted and reinstalled with the new one i bought. and it just keeps freezing. but when i put back that 30 day trial on, it works(which is why i can come here and ask for help). anyone else ever had this problem or have a solution? thanks in advance.
