Re: I've screwed up. Majorly.
Once you get your sig up it will help a little more, but just off of the info you gave us i have a few ideas.
try re-seating the RAM, its amazing how many problems this fixes. If that doesn't work, see how far the boot up goes when there is no power cord plugged into the hard drive.
if neither of these solves the problem start swapping out any hardware you can, starting with RAM and video card if you have one.
I do not belive this has anything to do with your windows re-format, it just seems to be a serious case of bad timeing.
