TLDR at bottom
It started back in 2016 when my PC would randomly shut itself off as if it had became unplugged. I suspected a bad PSU and used my warranty for a new PSU. Having had bad luck, there was a power bump and I am pretty sure it fried the PSU. I brought it to the repair shop and they replaced the old PSU with a new cheap brand and all worked well for a while. Some time later it began happening again and I decided to give my PC components a clean which fixed the problem. Just recently my PSU started making noises when being first booted up from sleep or cold boot. Eventually the sound would go away but my PC YET AGAIN started showing the same symptoms.
I decided enough was enough and even though my temps seemed normal, I bought a brand new case, heatsink, 2 new fans for more airflow and a brand new EVGA 650W GQ PSU. If these parts wouldn't fix the problem, I believe I have ruled out a bad PSU and/or high temps. Keep in mind I am not overclocking either. PC seemed to be fine for just under a week and then shut off.
My PC specs:
Processor: Intel(R) Core(TM) i7-4790k CPU @ 4.00GHz
MB: Asus Maximus VII Hero
RAM: 16GB
OS: Windows 10
GPU: NVIDIA GeForce GTX 980
PSU: EVGA 650 GQ
I am currently running memtest86 to see if it can find anything wrong within my memory. Will update with findings when it is complete.
Update 05/30/18: Memtest86 didnt find anything wrong after multiple passes.
Update 05/31/18: I have updated my BIOS and passed Intels Processor Diagnostic Tool.
TLDR: Replaced PSU and bought new aftermarket heatsink, fans and case to rule out any PSU or overheating problems (not overclocking). PC still randomly shuts off.
I appreciate any help and ideas. I am beyond frustrated!
If there is anything else I have missed, let me know and I can do my best to provide.
