PROBLEM SOLVED!!!

When I said that my the bug occurred regardless of voltage, I was refering to medium to high voltage settings (+.20 to +.35). What I did not try was normal/low voltages....it worked (now running +.10)!!! It's booting every time without the bug now at 456MHz FSB. All I had to do was leave the voltages alone, maintaining the settings I used for 400MHz FSB.
