Re-install the Cpu with new thermal grease.
I still find those memory jumpers confusing..... verify they are installed correctly!
* See pgs. 8 and 15.
What is the ampere rating of the 12volts on your PSU?
Can you have the Cpu tested at a local computer shop ?
** Don't let the warranty expire on your board/ Cpu before you do a RMA.
