Windows 2000 problem!

Im having trouble running epsxe, it used to run fine when i was running Windows 98 but recently i put 2000 proffesional in and while trying to run Gran Turismo 2 it locks up on the video screen just after the main credits. It does this for both 1.4 and 1.2. I am running an athlon 1.4ghz, 256megs of ram,with a voodoo 3 3000agp card and soundblaster live, it worked before when I was running 98 thats why i think its got something to do with 2000 please help if you can thanks
