Hi

Have you just installed more memory ? I am just unsure why this problem has just surfaced.

Did you also leave the BIOS settings on Auto ?

If so that is your problem. You have to compensate for the extra loading on the memory controlller and possibly alter the QPI/Vtt also. The timings will need to be inserted manually too.
