Seeking advice - Crash issues

Describe your problem. List any error messages and symptoms. Be descriptive.

The PC boots and runs stable on Windows for basic web browsing and daily use. Whenever I boot a game (tested PUBG, CSGO, OW) I am able to play for as long as I want, but the PC crashes when I close the game app to return to the desktop. After this happens the PC even crashes sometimes sitting on Windows just using Discord and Chrome.

No specific error message but the order of events for the crash are as follows;

• First few times it crashed the monitors shut off, the USB devices with LED lights shut off (but the laser on the mouse stayed on?), and the fans/CPU keep spinning. The GPU fans haven't turned on even when it is working so I don't know if the GPU is still running when this crash happens. NOTE: this happened with a 1050Ti and the 650Ti I slotted in while waiting for the new GPU.

• The next few times it has happened after troubleshooting and tinkering the screen simply freezes, I can still engage and disengage CAPS and NUM lock lights, and as before the fans and CPU are till running. Again, this happens when the game closes, and after rebooting from that it will sometimes happen on the desktop.

List anything you've done in attempt to diagnose or fix the problem.

Initially I assume the Ryzen 1600 was too much for the old and overused 650Ti and according to GPU-Z I was running the GPU at nearly 70C so logically I just assumed GPU overheating due to being so old.

When the problem persisted with the 1050Ti slotted in I got to digging for answers on Google. My CPU is running at a cool 35-45C idle and 50-60C while in games. The new GPU runs so cool the fans don't even need to turn on. My RAM is DDR4 Corsair Vengeance LPX 3200mHz which is a clock speed ASRock advertises is compatible with their mobo. I didn't realize there was a list of specific RAM models among specific manufacturers that are confirmed to work, and the RAM I bought happens to not be on there.

However, I've spoken with ASRock over the phone and discussed the RAM support issue. He said 3200mHz will put it in a boot loop, which it did at 1.2DRAM volts in bios settings. I've since walked it up at 1.2v, 1.35v, and 1.4v and I get the computer to boot and run Windows stable at anything from 2133mHz to 3200mHz when set to 1.35v or higher. However the crash occurs no matter what when I close a game, and will compound into crashes just sitting on Windows randomly if I reboot the PC too quickly after crashing. I've now walked it back down to 1.2v @ 2400mHz since that seems to be the manufacturer and user recommended settings for the time being.

I've got my RAM slotted to A2 and B2, recommended by users and ASRock tech support, and basically the guy on the phone told me at this point they wouldn't be able to troubleshoot it any more and they offered to replace the board under warranty. I don't want to do that, so I did more digging and found a user who turned his SoC voltage up to 1.15 in order to get his 3200mHz RAM running stable at ~3000mHz. Ryzen Master already has my SoC clocked to that by default so I am not sure it's the RAM at all at this point.
