Customer has Hp Pavilion 512n. Needs Ati or Nvidea video to play Sims game. No agp slot on m/board. We tell him we'll upgrade to 2.4 celeron and board with agp plus the ati card. Put it in new case, remove hard drive. Install in new machine, run repiar install off of Win xp home cd. Repair appears to work. Start, does not load os, just sits there and blinks at me. Have done this on dozens of other machines with success. Does Hp do something to the drives? Are they "locked" or something?
