Dr Debug on Asrock X79-Extreme9

[l3g10n]

When I restart my PC it freezes when trying to POST. Dr Debug shows b7 for a while then stops on b9 (or it could be 67 then 69 depending on how you read the LEDs).

The handbook isn't very useful - do you know what these codes mean?

I think I need to swap something, just not sure whether it is CPU, Memory or Motherboard.

Thanks for any help

try clearing the cmos? has it always done this or just recently

it started doing it when I first built the pc but an increase in voltage to DRAM (1.55v), VCCSA (1.2v) and VTT (1.2v) sorted it and it would boot.

now it is just when I restart the PC after it has been on for a while.

I did get BSOD but I did a BIOS update a couple of weeks ago and no BSOD since.
