To be clear, the system just shuts off then won't POST? You're not seeing a BSOD? IS the RAM running at 4800 or 5600?
When that DRAM LED comes on, does it stay yellow, or switch to red then yellow? Does the system seem to be restarting every 30 seconds or anything?
It strikes me as more of a board power issue. It's restarting and that generally indicates a brief power loss, but you get the DRAM error on startup. Now it doesn't try to retrain or anything, so I think the DRAM is indicating that the IMC fails to initialize. It's more of a CPU memory controller issue than a DRAM issue. You have to clear caps to POST again.
What BIOS version are you on and are you doing anything specific on the system when this happens?
Worth trying the 1222 BIOS with the AGESA 1.0.0.5 firmware. My feelings are that this is a power issue. I'd swap the PSU, though based on the symptoms I think motherboard VRM is more likely.

When I first built it I did try to swap the PSU out, and it would still turn off randomly. I was thinking of trying a different Mobo. I have been looking at the Strix B550E-E.
The Strix B650-E is a good board. It's a guess at this point, but the power loss I would assume is on the board if you've ruled out the PSU. Possible it's a GPU issue where you're losing video and crashing, but you can't see the BSOD, but that wouldn't explain the failure to initialize the IMC most of the time.
Update:
So after a few days, I swapped out the Motherboard. The issues with the DRAM light staying on seem to have gone away. However, when I close a game after playing for a little bit, the computer restarts again (it starts up just fine when it does this). But again there are no BSOD errors or anything like that. This has happened on two different games and I'm not sure what's causing this to happen. I have run sfc /scannow and it did say it fixed some corrupted files, but the issue still keeps happening
My thought would be it's a voltage issue when the game stop and the voltage drops it's causing the reset. Check your BIOS on the right side see what your CPU voltage is and the load line calibration level. It should say like 1.24V @L5 as an example.
You can try AI Tweaker Digi + VRM - CPU Load-Line Calibration. Change it to level 4. See if it's the idle CPU vdroop that's causing the restart possibly.
Set the power plan in Windows to High Performance as well. See if that has any effect. Did you exchange the board or swap to the Strix B650-E?
The power plan on Windows is already set to Best Performance. I did exchange the board for the Strix B650-E
Just out of curiosity, could my CPU or GPU be bad? The GPU was an open-box purchase from Micro Center. Everything else was purchased brand-new.
You ruled the board out. GPU is possible, but you should see a crash in event viewer or a minidump. It sounds like it just restarts. Double check C:\Windows\Minidump. See if there's anything in there.
That means the system has never logged a crash. It doesn't create that folder until the first time it does. So this just the PC restarting. Given the indication is that the system hangs initializing the IMC, and that's on the CPU, I'd swap the CPU first.
