I have a Windows 98 PC in which I recently installed drivers for a "SoundBlaster PCI 128" sound card. 3D games or more modern ones like Diablo, Half-life, Fallout 1-2 crash immediately and locks up system. Upon launching Doom 95, where it says what it is loading it stops at setting up sound. I checked for IR and DM conflicts and I don't think there is any Sound Card settings for any. My specs are (in case you think it's a hardware issue).
