Asus Rog Maximus x Hero Wifi AC
I7 8700k (delidded was overclock at 5 ghz at 1.250 volts)
G.Skill trident z RGB 16 gb
Last night I was just casually playing destiny 2. Before i hopped off I shutdown my computer. Wake up next morning tried to turn it on no display from gpu (even used onboard graphics still nothing). Disassembled the entire build and started troubleshooting. After a couple of hours messing plugging and unplugging components, I got it to post and boot into bios, hurray!
Then I restarted my pc a coupe of times to make sure the problem was fixed. After my second boot I was convinced that it was fix, so I post into bios but this time I only changed the fan curve. Sure enough as soon as I saved and restarted I was back to square on, q code 00.
So I disassembled my pc again took out the cpu and checked for bent pins in the socket (there werent any), cleaned the contact pads with isopropyl alcohol and unplug and replug the 8 pin cpu connector. And guess what it booted again! So I did the restart test again and it was fine!
Until I entered bios and redo my overclock, saved and restarted and once again q code 00. So now im stuck and its getting late and I have an essay due tomorrow.
From my experience I can conclude that the cpu wasnt at fault since it was still booting time to time. It wasnt a corrupted bios as I reinstalled the bios (through bios flashback and normal flash after I got the pc to work for a while).
So my two main culprit are, my psu or my motherboard. Psu could be failing to supply sufficient voltage and power to the cpu. There maybe a short in the motherboard or something like that.
Now im stuck deciding what to do. Should I try to go for an RMA and if so which one? As I do not have a spare motherboard or psu lying around.
