Reboot Error

Ok, having a problem with my parents PC, my old one as a matter of fact.. Well, I installed a new hard drive 40gb.. cause I thought this reboot error was caused by the old 5yr old hard drive.. Well.. seems the hard drive wasn't the culprit.. and I'm ready to throw this thing out the window.. I took the network card out.. stable after that, then reboot the machin and back into the reboot loop.. well.. I'm about out of ideas... Anyone got any idea whats going on with this thing...

Maybe its possesed.. dang Bill Gates probably sold my computer's soul or something..

Ok, got it stable, for now... Gonna go update to SP1 since I already did the work around ;)
