Been trying to install a Diamond DT0398 sound pci card in my ABIT ST6 mob. Disabled the on board sound in the bios, removed the sound in device manager and removed the drivers. When I reboot it keeps installing some windows sound drivers that don't work and when I try to install the diamond drivers I get an error msg and the comp. locks up. Has anyone been sucessful in installing a pci sound card in the ST6 and can anyone give me any help? thanks
