I have PIII 550 mhz box. Trying to install Soundblaster Audigy Platinum soundcard. Initially couldn't get to recognize the hardware in the PCI slot. Seemed to get the drivers installed, though I noted VERY long time to install from CD, and I thought might be bad disk initially. Finally seems to recognize the soundcard, but on start-up get two error boxes - "soundcard not installed properly" (paraphrased), and no sound. Tried different PCI slots, triple- checked all connections. Note I do recall had problem before installing LAN card and drivers and think had to reload whole operating system per my tech assist. Also note had to reinstall video card drivers a month ago or so. A friend said I need the drivers for the motherboard as something with the soundcard is not being recognized?? Problem is had box put together and have none of this. The computer seems to be running slower than usual, and on start-up the icons take a few secs to draw and was blazing. Have 30 gig mem 1/3 full. Any ideas?
