Critical Errors and warnings

[Lespaul678]

I have been getting these errors more and more lately and I'm starting to get really concerned. I have adjusted settings in my BIOS numerous times and even went back to complete default settings mode.

Even with doing that, this still seems to happen randomly. I can't specifically recreate the error when I want to, it just sort of happens.

I have done some research, but I'm not a huge pc nerd. I do know my way around computers but this is beyond me

My mobo has a memtest function on it and I have run it several times and every time it has come back perfectly fine.

I don't know what to do.

My specs are -
i7-7700k @ 4.5
RoG Maximus IX Hero mobo
16 GB Trident RAM @ 3866
GTX 1080 FTW

When these errors happen, my pc either does a hard lock or just a reboot without any warning or anything!

I also have an 850 watt PSU. I ordered a different heatsink and some more fans. I have plenty of air cooling as is, but I figured more/better/newer fans won't hurt either.

I was thinking about also ordering a new PSU. Maybe a 1000 watt modular in case it's my PSU.

Help!

Unexplained PC reboot to cause the Kernel-Power 41 (63) error. And ocing, overheat, driver, even the bad hardware, etc related to that problem.

So:
1) If you oc the cpu, reset it, also set the RAM speed to 2133mhz to see the PC runs fine or noy.
2) What brand is your PSU? If you have the good brand 600W PSU, it will be more than enough, the 1000W PSU does not hurt either, but just overkill.
Also you can go into the BIOS, hardware monitor or PC health monitor section, something like those, to check the +3.3V, +5V, and +12V. You want to see those voltages are within +/- 5%. If they are, the PSU is fine, otherwise the PSU has problem, you will need the newe PSU.
3) Even you can try take out the gtx1080 TFW, using onboard iGPU to see the PC runs fine or not. Or test the gtx1080 in other PC.
4) Check the cpu or GPU temp with HWiNFO64 or the software came with the EVGA.
