I bought an Elsa GeForce 256 used from a guy and it seems to be FUBAR. First I tried it in my kids PC which is were I intended it to go. It had a VooDoo3 3000 in it and I uninstalled everything and slaped in the geforce. Everything looked fine until I tried any 3D games locks up imidiately. I figured there was some left over conflicts with 3DFX and Glide so I installed it in my PC A Soyo 6BA+4 BX board that has only had my Geforce2 GTS on it. Same thing locks up in 3D games. I am using 6.49 drivers on both PC's the main game i'm testing with is UT. I have used safe mode and disabled most everything but it still locks up like it's over heating. It looks like it has the original heatsink/fan on it and appears to have never been messed with.
I am using just the nVidia drivers not the ones from Elsa. My brother owned an Elsa Geforce 256 card and used nVidia reference drivers with his card with no troubles.
Any idea's on what else to try?
