Frequent HARD FREEZES after 1-2 hours of usage

It sure does sound like a power or a temperature issue. I didn't recognize the PSU brand and did a quick google search. Looks like that Rosewill Valens -series isn't very good:

The link takes you to the conclusion page, but it seems like it's the DC output that's the weakest part. The summary of the DC output testing is:

"After the very nice start the VALENS-700 had today, the overall DC output quality is lousy. And not just lousy, but failing in a massive right turn into a wall kind of way that hits so hard I should have been wearing a HANS device just watching today's chain of events.

In our testing today, the VALENS-700 started off with rather active traces on the 12v rail but quiet traces on the minor rails. However, during testing all of these values increased dramatically (and differently depending on the AC input voltage) to end out of specification on the 3.3v rail and very high on the others. How bad was it? Well, the 12v rail peaked at ~85mV of ripple/noise and the 3.3v rail did its very best to match that at ~75mV of ripple/noise (the ATX12v specification limit is 50mV). The 5v rail was no saint either as it peaked at ~40mV of ripple/noise during our testing. All things considered, this was just hugely disappointing given our other metrics today and this unit obviously trails the passing Enermax MODU87+ 700W, LEPA G700-MA, and the Rosewill Capstone 750W. Let's move on now to see how this all wraps up (you might be able to guess at this point)."

The big reason high ripple is bad is that it can damage other components. Quickly too, if the ripple is bad enough. It can also make it harder to overclock. If I'm not mistaken, you're running your system at stock settings. At stock, my system's Vcore was bouncing all over the place, so if your system does the same, it would sort of makes sense that combining the half-mental auto setting of the BIOS with ripple from the PSU could cause instabilities. Especially if the ripple gets worse as the PSU warms up. Now, I know this is very "hand wavy", but if I were you, I'd try to install another PSU and see if the freezes still occur.

I also started swing hard freezes on my B350M Win10 build the last couple of weeks. What I have done so far:

Clocked down Ryzen 1200 to default
Update BIOS to 3.3 from 3.1
Update AMD chipset drivers and power plan
Set memory voldtage to 1.35
Set VDDP to 1.1

Next set of action is CMOS clear.

OMG. That's bad, mkay!

TBH, these new PCIe retention mechanisms prove to be troublesome for many.

Now it's a chance to grab a Taichi!

Not a huge selection of M-ATX boards at my local dealer.

Attaboy!

I usually use my 12ga shotgun for skeet shooting bad electronics/stuff I hate. No kidding. Someone behind me throws it in the air and I shoot it. Feeling is priceless!

Hope you have more luck with the MSI as they are not particularly known for great products. Please do come back and do tell us how it went with the new mobo.
