refreshrate problems with windowsxp

im running on a p4 4500 with nvidia gforce4 4200 on windowsxp, i cant get the fps to go any higher than 60 and have downloaded almost every fix available on the net but nothing seems to work, if anyone knows a program or steps to fix this it would be much appreciated and im not a genius so if theres some trick to running it that would help to

oh yeah and i dunno what everyone is saying about vsync, but ive f*kin looked to disable it everywhere and its not there so thats not the problem
