Hmmm,
Will get back to this thread, Currently working on over clocking a T7400. Happy Holidays and modding. I get that error on an old HP DC 7800 small for factor. Replaced the Q9300. Put that cpu into another board. Replaced it with an E6400
which will be OC with a pad mod.
Computer runs fine with 64 bit Vista Business. With that error on Boot up.
