Win ME/Ati Radeon 64ddr/Homeworld not working together

Just installed a Radeon 64ddr, and a 21" monitor. Everytime I try to run Homeworld, system freezes! System is Asus B3-f w/128m pc100, 18gig hd, 16xdvd/40xcdrom, 600mhz pent III.

Gone through all the paces, check for new drivers/patches for ME, video card, game, ect.

Suggestions greatly apperciated!
