D1esel: A Man after my own heart!
Nate: I finally got XP to install on my 780ftw after a week of farting around with it. Turns out it was the BIOS all along. Be sure to clear the cmos, then before installing windows, go into bios and reset everything to failsafe defaults (or whate ever it's called..not sure you really have to do the fail safe thing, but it's what I did), then proceed to set it up like you want it. Be sure to disable all those spread spectrum and C1E settings. F10 and see what happens.
