  1. A bad CPU won't post ,,, period ....You seem to have checked everything except maybe the video cable from the card to the monitor, too bad you do not have another mobo......
    EDIT>>>> Check system battery.....:)
  2. Thanks amigo. I replaced the battery and then reflashed the BIOS. Worked. Now to get past the blinking underscore...

    Repaired Windows startup files.. no avail.
