Still comes down to 50/50 chance on the Motherboard or CPU being bad.
I had a problem with a new motherboard (an ASRock) from Newegg. It had a bad memory slot on the motherboard as diagnosed by ASRock. I returned it to Newegg and they wouldn't accept it as "bent CPU pins" in the CPU socket. There were no bent pins but they were set on that and returned it. I found out from searching the web that others had the same experience with Newegg. I went back to ASRock and finally (after several e-mails) got a replacement. Because of that I no longer buy from Newegg.
