voodoo2 + riva 128 = Lockup?? HELP! Please

[busydude]

I have a celeron 333 system with a Elsa victory Erazor(Riva 128) and have just added a Quantum3D Obsidian2(Voodoo2)card. I can't seem to get the combo to work for my games. When I start a game (directX or GL)it locks up. It's as though the cards are fighting over who gets 3d duties. I have tried everything recommended at both mfg. web sites, to no avail. Any suggestions? TIA!

What games are doing this? have you tried going into the configuration and picking one? Also, what Obsidian card do you have? If it's the X-24, you might want to try disabling SLI, if only temporarily.
