[SOLVED] PC Shuts Off Randomly When Using It

[CaptainDiabeto]

My PC For The Most Part Has Done Pretty Well In The Past With No Significant Errors/Crashing, Until 3 Days Ago.
Now My PC Wont Go 5 Minutes Without Shutting Down & It Does It Randomly; Sometimes In Windows, Sometimes When I'm In The BIOS & I'm Completely Stumped.

Here's A List Of Things I've Tested That Aren't The Cause Of The Problem:
My CPU
GPU
PSU
Windows Installation
BIOS
Power Cable
Wall-Socket
Monitors
Monitor Cables
Optical Drive
& Hard Drive

I've Tested Everything Under The Sun Apart From The RAM, CPU, SSD, & Motherboard & It Still Randomly Crashes.

I Haven't Made Any Changes To The PC: Haven't Installed Any Suspicious Software, Updated The BIOS/Drivers, Haven't Changed Out Any Hardware; The Problem Just Seemed To Come Out Of The Blue.

I Also Reseated The CPU Cooler & Applied New Thermal Paste (Even Though The Resting Temperature Before Was Still Around 50℃) & That Still Didn't Do Anything, And I Can't Even Run A Memory Diagnostic With It Crashing. My Biggest Point Of Focus Now Is The RAM, But I'll Have To Wait Until I'm Able To Find New RAM.

Here's The Specs Of My System:
Ryzen 5 3600X
MSI B450M Pro-VDH MAX
Nvidia GTX 1060 6GB
2x16GB 3000 MHz DDR4 RAM (Brand: OLOy)
APower AK Series: 680W PSU
256GB SanDisk SSD
2TB Seagate Barracuda HDD

I Have A Video Project For School That I Have To Edit, And This Is My Only PC, So I Will Greatly Appreciate Any Advice Given To Help Further The Cause Of Getting My System Working Again.
Thanks For Any Future Advice!

(P.S. All My Computer Parts Are Within 1 Year Old, Except For The GPU, But That Has Been Tested Working)

are temps normal before it crashes?

imo it does seem like a memory problem, but someone else might have a different opinion.

That PSU Apower AK 680 is an unrated low quality PSU and a weird wattages number. Not even in PSU tier list and was released November 25, 2008. 13 years old model.

If you tested another PSU was it a good model or it was a PSU like the one you're using?

A system shutting down is normally caused by overheating, PSU or a GPU issue.

Faulty RAM can cause a shutdown but it does not rank near the top for reasons why the shutdown happens.

Yup, they don't spike, so I don't think it's overheating

The 2nd PSU I tested was a Corsair CX750M. A Bit Old, But It Was Pulled Out Of My Server Computer & It Was Working Just Fine In There.

That's good to know. Corsair CX750M is a good entry Corsair PSU.

Did you manage to resolve this issue?

Unfortunately Not, I Have Gotten The Motherboard Back From Being RMA'd, And It Sort Of Bent My CPU Pins Due To A Faulty Latch Lever (Note This Is Still After It Got Back From RMA), So Now I Have To RMA The CPU.

Turns Out My Motherboard Was Garbage, I Bought A New Motherboard, Replaced The Old One, And It Was As Good As New
