Custom AMD PC - Randomly shut down, will not power on

Hello, I built a custom PC in December; I used the PSU from my prior custom PC, as well as the Primary SSD and the secondary HDD, but I formatted the SSD and ran a clean version of Windows 10 on the new system. The whole setup process went flawlessly, and it was the perfect model of how every custom PC build should go.

Roughly an hour ago, however, I came back to my computer from watching a movie with my family. I woke it up by pressing a key on my keyboard as I always do, and logged into my account. I did nothing out of the ordinary. A couple minutes into waking up my computer, however, I joined my friend's channel on Discord, said a few words, and tried to scroll through the user list in the right panel. The scroll bar froze, acting as if it were resisting the scroll wheel (going down) by rapidly scrolling up. I went to go click the scroll bar to drag it down, and my system shut off - killing the displays, turning off my mouse and my keyboard, and leaving only the motherboard AURA LED's active.

This wasn't any typical shutdown. I have had similar occurrences with other systems where they randomly shut off, but I just held the power button until it was off completely, pressed the power button again, and the computer would boot up as if nothing ever happened.

Instead, my system just stopped working altogether. The power button and reset button did nothing, and my computer did respond at all. I reached behind, flipped the power switch on the back of the PSU, watched the AURA LED's turn off, and held the power button for 10 seconds, as usual when powering down a system to work on it. I flipped the power supply switch back into the on position, the AURA LED's came on, and it did exactly what I described after it shut off the first time. I pressed the power button, and (instead of doing nothing) the case fan LED buttons flashed once along with the LED's on my CPU cooler fan, which nudged very slightly, and nothing happened.

I have pictures and videos of all the events described above, as well as general pictures of the connections to the motherboard inside of the case. After all of the above, I pulled my computer from under the desk and disconnected everything but the cable for the power supply, but this has had no new effect.

My build:
ASUS 970 Pro Gaming/Aura ATX DDR3 AM3 Motherboard
Thermaltake Level 10 GT
AMD FX-8350
Kingston HyperX FURY 16GB Kit (2x8GB) 1600MHz DDR3 CL10 DIMM - Black
EVGA GeForce GTX 1050 Ti SSC GAMING ACX 3.0, 04G-P4-6255-KR, 4GB GDDR5
CORSAIR CX-M series CX750M 750W 80 PLUS BRONZE Haswell Ready ATX12V & EPS12V
Cooler Master Hyper 212 EVO

Any and all help is welcome; I have tried everything I can think of at the moment, and I will continue to troubleshoot inside of the case. I will post updates if there are any, but I am hoping to come to a solution that I can manage.
Thank you in advance, and please let me know if you need any clarification

UPDATE: I removed my graphics card and tried booting. The computer responded as per usual, posted correctly (although the speaker beeped the post message for no GPU detected), and although I could not see a display, all of the internals ran as they were supposed to.

Does this mean my graphics card is dead? I plugged it back in afterwards and received the same results as before. I am going to a friend's house to test the card, and I am going to contact EVGA depending on my results.
 
Just in case anyone comes along this thread looking for help, I removed my graphics card and the system booted up, posted (my post speaker beeped that there was no VGA device), and everything worked.

I followed this up with a post on EVGA's forums: https://forums.evga.com/System-crashed-and-unable-to-boot-m2664119.aspx

and have issued an RMA

To sum everything up, my computer turned off out of the blue and would not boot back up when my graphics card was in either PCIe x16 slot. My graphics card is presumed dead and I am issuing an RMA.
 

The computer worked flawlessly for five months, running dual monitors and overwatch on max settings. I did, however, try another graphics card I have laying around and it booted correctly.
