I've been running my PIII 1gig @ 1500 with a Hercules Geforce 2 64mb and 3DMark 2001 with no problems. Today I installed a new Visiontek Geforce 3 and 3DMark2001 won't run. I have uninstalled and reinstalled un-overclocked and still it won't work. I try and open the program and it won't run. I am using Direct X 8.0b and Nvidia's 12.40 drivers. Anyone else with this same problem and hopefully a fix?
