MY specs are:
Ryzen 5 1600 with stock cooler no OC
ASUS Dual RX 580 8GB
MSI B350m Mortar
G. Skill Tridentz 8GB x 2 3000MHz running at XMP profile 1 at 2667MHz
SeaSonic S12G 650W
1 KVA UPS
Windows 10 Home

The following file is the log of system events from when I shut down the PC initially.

https://drive.google.com/open?id=0B5A6YFsvCmiddjdBRDkwTlFzTDA

I came across that after the problematic boot, my memory was set to 2133 MHz even though XMP profile 1 at 2667 MHz was activated. I turned the profile off, restarted, then turned it on again. The memory was back to 2667 MHz. But the next boot again went into cycling. I fiddled with the power button and got it to boot somehow(yeah I know) and again the memory was set to 2133 MHz. I have since turned the XMP profile off and the problem has not occurred.

But it was running fine at 2667 MHz for a month? Does this sudden problem mean the mobo maybe dying or something?

It wouldn't post and the RAM RGB wouldn't come on, only the Mobo power indicators and case fans would cycle on and off several times.

Meaning the slightest change in voltage can send it crashing. So far it's been behaving and indeed you might be able to get it working again by simply playing around with the settings. I haven't done this manually so I hesitate to advise you on how to do it.
Here's a nice review on ryzen, memory compatibility and playing around with different frequencies:

Again, definitely try the 2933 preset (should be available under xmp in your bios), and update your bios first and foremost as there were updates to memory compatibility for ryzen:

Your mobo's spec page lists memory compatibility as such:
1866/ 2133/ 2400/ 2667(OC)/ 2933(OC)/ 3200(OC)+ Mhz

so technically it should be able to run it. It could be it just doesn't like timings on your particular memory stick. Your model has actually 3 different sub-models with three different timings:
http://www.gskill.com/en/finder?cat=31&prop_3=3000MHz&prop_4=0&prop_1=0&series=2482&prop_2=16GB+%288GBx2%29
I don't know which one you have, but one of them may not jive with your mobo at 2667MHz. Or could be just on the limit of stability, so you've had it functioning ok for a while and now it won't. There are ways to adjust memory OC voltage/freq but I don't know enough about this to advise you, wait for someone else to chime in.
All 3 on that page list only z and x board compatibilities, so I'm guessing it was never tested with your board.
Try a 2933 clock and see if it fares any better. If not, go back down to 2400.
Also, get the latest BIOS for your board, as the latest mentions improved memory compability:
https://us.msi.com/Motherboard/support/B350M-MORTAR.html
Finally, this could be a ryzen compatibility issue. I've heard ryzen tends to like the higher 3200Mhz. Here is a nice thread of people discussing msi board/ryzen/memory compatibility so you might get some advice there:

which have then been included into various bios.
