I recently upgraded my CPU fan and ram the pc wouldn't boot and i needed to rebuild the pc 3 times over, once it booted and had a blue screen for not having enough power but after a few rebuilds it started to boot in windows. When booted into windows the CPU is stuck 0,78GHz and not 3,8GHz. In IETU (Intel extreme tuning utility) it says it's thermal throttling i have a ss here: https://gyazo.com/003150cc2abcc0ec0f126fce1348f906
I have an INTEL i5-8400
Also i think this might be a PSU issue any thought's?
Also this is what i upgraded:
Intel stock cooler -> Cryorig H7
8gb ram -> 24gb ram
