    Unable to boot with all 4 cores active. (QX6850)


      I recently sold a QX6850 Core 2 Extreme CPU that had been laying around.  The buyer claims that he could not boot it unless 2 of the 4 cores were disabled. Does this make sense? It has occured to me that the problem might be in the CPU but that there are other possibilities:

      1) the motherboard isn't compatible.

      2) the motherboard is defective

      3) his power supply isn't big enough

      4) the bios isn't configured correctly.

      Any thoughts as to what is causing the problem and how can we determine whether or not the CPU is defective?
