System Issues after adding nVME - Swap Motherboard or Full upgrade - 3700x -> AM4 or AM5 or ???

[Emmortal]

So I've come into an issue that seems to be forcing an upgrade on me. Just not really sure how much of an upgrade I need or should go for.

Note that I'm in Canada, so any costs will all be in CAD, with canadacomputers being my dealer of choice. 

 

My System:

 

CPU: AMD Ryzen 7 3700x
Motherboard: Gigabyte AB350 Gaming 3
RAM: 32GB Corsair Vengeance LPX 3200MHz (4x8GB) - currently only running 16GB - see issue below.
GPU: Gigabyte RTX 2080 Gaming OC
Monitor: Dell S3422DWG Ultrawide WQHD 3440 x 1440
PSU: Corsair 750 watt

OS: Windows 10 Professional x64

 

Primary use is a mix of gaming (survival and RPG's mostly, with the occasional AAA title), productivity, and occasionally some 3D modeling and game programming.

 

The Issue:

 

This arose when I picked up a WD SN770 2TB nVME SSD. What (I thought) should have been a quick upgrade--install drive, move any drives off now-disabled SATA ports, reboot, profit--turned into an entire evening of headaches, troubleshooting, and a rather sore ass from sitting on the floor under my desk for most of the night.

I installed the M.2 drive, moved my existing drives off the SATA ports which would be disabled per the manual, powered on the system, and was met with a system that wouldn't even post. It just turned on for about 15 seconds and restarted, and would do this forever (when I first bought this board, it did this about 3-4 times then started normally) if I let it. It would never even get to sending a signal to the monitor.

 

Troubleshooting Steps Taken

1. Reseated the video card - No Post

2. Removed and reseated the RAM - No Post

3. Disconnected secondary HDDs from the SATA ports - No Post

4. Removed the new nVME drive - Posted & Booted to Windows 

5. Reset BIOS to defaults and re-installed nVME - No Post

6. Removed nVME drive, updated bios (F51b -> F52i) - Posted (Reset BIOS Defaults, Re-Enabled XMP Profile) & Booted to Windows

7. Re-installed nVME - No Post

8. Removed nVME - System doesn't go into the restart loop, but now just sits with no signal to monitor

9. Removed nVME, Removed battery (20+ minutes), cleared CMOS, - no change 

10. Removed all but 1 stick of RAM - Posted (Reset BIOS Defaults) & Booted to Windows

11. Re-installed all RAM - System doesn't restart 

12. Removed 2 sticks or RAM - Posted (reset BIOS defaults, no XMP) & Booted to Windows

13. This is where I'm at right now posting this

Thoughts:

 

I've had a few issues with this Motherboard since setting up the system originally with a Ryzen 5 1600. Every upgrade seems to cause instability and takes hours to troubleshoot but does eventually stabilize.

That said, I'm thinking it's time to ditch the Motherboard. I'm just not sure if I should:A) swap out the board with something more reliable and robust orB) suck it up and do a full system upgrade to an AM5 board with new CPU & RAMC) suck it up and do a full system upgrade to Intel

I know AM5 is the way forward for this platform, but do you think there's still some significant life in AM4?

 

I'm aware this will eventually come down to if I want to spend $200 or $1k, so really looking for opinions, but if someone has some insight or solutions into the issues with my current setup I'd gladly save the $$$ for now. I WOULD very much like to be able to use the nVME I just bought but returning it is an option.
