New Motherboard Losing Hardware, etc

I just installed a new motherboard with a via chipset and an AMD K2/450 processor /64M. At first I couldn’t get the stealth 450 video card to be recognized so on advise I installed a VIA 4 in one patch. Wrong! Now my primary and secodary bus are not working so no cd rom or cd burner. I tried reinstalling drivers but I keep getting message “can’t find driver”. I am at a loss of what to do next.
