That might be your problem, at least going by my experiences with S3 
cards. *blech*

What are the beeps? Normal POST, or a beepcode
Long-short-short-short
then boot as normal? If its the latter, your BIOS is failing to init the 
video for some reason - perhaps the S3 is somehow interfering with the 
TNT2 (IRQ conflict or maybe even nasty IO range grabbing stuff). Try 
different slots as Greg suggested, and have another look through the 
BIOS for where to set which bus is primary vga on boot.

If you're not getting the BIOS beepcode for "no vga found, booting 
anyway" as above but the normal "POST OK" one, yet you still don't get 
video, its more likely that something is confusing your primary video 
card (usually the AGP one but picked by BIOS) and causing it to fail 
_without_ reporting failure to the BIOS. In that case, try another PCI 
card - can't think of anything else, really.
