So then I took the CPU back to the store I bought it from and got a new one, which also generated a CPU error.
Then I ignored the problem for a while and realized that the time for returning the motherboard to the mail order company had passed.
So I got a new version of the same mother board. I tried the CPU and it failed in the new motherboard.
Then I tried a different power supply.
My remaining theory is the first motherboard was so bad that it damaged the chip. Unfortunatly the best way to test that is to obtain and try a new CPU, dropping even more money into this foolish quest.
The other possible things that haven't been replaced were either the CPU cooler or me.
