I've had two CPUs die in the last 4 months. Is part of my system frying my CPUs? Or is it just bad luck?
I built my first system in April 2019 (specs below) and it ran without a hitch for over a year. Never overclocked anything except bumping the RAM to 2933MHz (it’s rated for 3000MHz). August 2020, it starts to get occasional BSOD with message “WHEA UNCORRECTABLE ERROR,” or when starting up it would give blank screen and the mobo’s CPU error light. Restarting fixed both issues for a time, but eventually every startup had a blank screen with the CPU light. I went through all of Intel’s normal troubleshooting steps (cycling a RAM stick through each RAM slot, removing the GPU, resetting the BIOS) but always the CPU light and no display. In September, Intel decided OCing the RAM above 2600MHz (their recommended max for the 9600K) had damaged the CPU, and they exchanged the CPU under warranty. I put in the new CPU, everything worked perfectly (RAM at 2600MHz), and I thought my troubles were over. Fast forward to yesterday, and it’s back to not starting up at all. Same as before – the case fans and lights go on and stay on, but the mobo’s CPU error light goes on and there is no display. I’ve tried Safe mode, removing the GPU, cycling the RAM, and resetting the BIOS, but nothing has worked.
If I need a new CPU, I need a new CPU, I can get on board with that. My question is, is it possible something in my system is responsible for two CPUs dying in close succession? What’s the most likely culprit? It seems unlikely to just be coincidence. I obviously don't want to replace the CPU if it's just going to die again.
