DJ, closest thing that your experiencing that has happend to me was when I had raid drives and upon POST some similar symptoms occured.
Slap an old hard drive in her and try to get to where you install Windows. If you can't get that far, then motherboard, memory, or cpu problem (s) someplace I suppose.

p.s. hope being without Aces High for a short time doesn't make exile in Hawaii too insufferable.
