ok, finally got past the agp440.sys crash reinstalled windows. Every once in a while I still get a sytem halt on boot, but at least she's usable. I attempted to put in a slave drive, I have it hooke up in the same line as my CD rom (my primary is on a different line) and BIOS wont recognize it. could this be a jumper thing? I've taken out and put back in this drive all day on my previous Pc with no issues. Does my BIOS in this new mobo play a roll with jumper settings?
