I'm freaked out. Have built almost two dozen systems over the past 15 years and I've had the usual amount of hardware fails -- a few motherboards that had issues, a failed gpu, etc. Never had a CPU go bad. Built a new rampage V ed. 10 w/ i7-6900k about three weeks ago and this week in the middle of reading my email (very demanding) it shut off. Dreaded debug code of 00 and the CPU led on the asus board indicated failure. I didn't believe it and replaced the mb and same deal. I've never had a CPU fail. Other than running the memory at the xmp profile, this wasn't an overclocked system. Am I crazy in thinking CPU's never fail? Especially after a three week break-in and no OC? Sigh.
