Computer Randomly Crashes and Previously Went into Power Loops

Howdy,

Last night I moved my PC into the living room to use the oculus rift with some friends who were over. After they left, I decided to try to get my case fans working, because only one had been working and then the other stopped as well about a week ago. I have a Phanteks Enthoo Pro, and I've had issues with the case fan since I got it about 8 months ago. Anyways, I determined that it must be the fans, because they don't spin at all, even on startup whether I am using the fan hub or the motherboard fan headers. Meanwhile, the CPU fan will spin on any fan header.

Thats a fairly easy fix. I imagine they became burnt out because I never hooked up the SATA cable out of a mistake so it was being regulated only by the CPU_OPT fan header on my motherboard which apparently can be bad is what I read while troubleshooting for ideas last night.

THE MAIN ISSUE: Today, after moving my pc back into my room, the computer started doing a power loop where the fans spin and the lights come on and it works fine for about two seconds before shutting off. After unplugging the fan hub entirely, the pc worked fine for about an hour where it abruptly shut off while I was gaming. It said windows encountered a problem and had to restart, but then went into another power loop. After that, it wouldn't boot again at all. I reinstalled windows completely and formatted my SSD, but now the computer is very finicky even after the reinstall. It works perfectly, and no more power loops even though there are crashes with the windows encountered a problem and needs to restart message. BUT, while I was plugging in my microphone it gave the windows needed to restart message again, but it restarted fine afterwards and worked perfectly. I plugged 3 other USB devices in, with two of them not causing a problem at all where as the 3rd one crashed the system again. I'll update this if it keeps crashing while I game, but I have no idea what the issue is.

Its not windows apparently, and everything worked fine up until I plugged in a USB device into the motherboard which is a bit worrying. I made sure to keep touching the metal part of the case whilst messing with it last night and it isn't a consistent issue which makes me almost think it could be a loose connection or something that freaks out when its bumped? I'm checking all the wires again, but I wanted to consult you guys for some other solutions or ideas to try. I want to prevent any damage (or further damage) if I can. I have three new case fans coming in tomorrow.

Thanks for any advice.

Here are my specs:

Gigabyte GA-Z270XP-SLI
8gb Corsair Vengenance LPX DDR4 3000MHZ
i5-7600k
Hyper 212 EVO
EVGA SuperNOVA 650w G2
Gigabyte GTX 1080 G1
WD Blue 1TB Hard Drive
Samsung 850 250gb EVO
Asus DVD-RW 24x
NZXT Hue
Elegato Game Capture HD60 PRO


EDIT: So,the PC went into another power loop and I tried disconnecting my graphics card and all extras. Turns out, taking out one of the ram sticks allowed the device to boot. Now it is out of the powerloop and seemingly working for the time being, but I'm 99% sure the issue is not solved. I'm about to run memtest86 to see if the RAM is faulty. If that fails, I will try to find alternative possible reasons for the crashes.

EDIT 2: I ran the memtest 86 with each of the two Ram sticks (4gb each) individually and they both passed, and upon putting both in it passed again. No errors at all. Interestingly, since that, I haven't had a crash yet. I also, however, removed the battery from the motherboard and all that jazz because I read that can help too. Any insight into what might be happening so I can fix it if it reoccurs soon or ever happens again would be much appreciated.
 
Solution
Final update: For me, I believe I dislodged a stick of RAM and removing it and replacing it again seemed to fix the problem. It is, however, possible that the solution was instead removing the motherboard battery and resetting all of that junk. Either way, if you run into a similar problem, I hope this helps.
