Dono what we did wrong, followed the destructions to a T.  But every time we tried to boot it up, it'd get to the black windows screen, instantly flash bsod, then reboot... over and over and over.  Not once did we get it to boot.  3 hours later, we figure we'd throw the stock stuff back inside.  Now bios wont even load!  What the heck could possibly go wrong?  I have never had a problem upgrading a machine, but this one is way beyond me.  its going into a computer shop tomorrow to get them to fix it.
