Help new celeron 600 doesn't boot

[NTD]

I just got a new celeron 600 for my BM6 and well it doesn't seem to want to boot. Once I put my old CPU back on my system boots again. I have flashed to the latest BIOS version. Anyone have any suggestions? Maybe my chip is DEAD?
Should I have reset all the settings in the bios to default before installing the new CPU?

Plug your Celeron 600 back into the BM6.

Use your CMOS Clear jumpers to clear out all past data. It's probably running on old voltage and fsb settings that your old CPU was running on and that's why it's not booting.

If all else fails, shrug.
