After replacing the motherboard, there was an issue with Battlefield 2042.

I believe the VRM of the B550M motherboard is not the issue because it passed the CPU FPU stress test, Ryzen Master overclocking test, and can run World of Warcraft, Overwatch, and Black Myth: Wukong without problems. I switched back to my old motherboard without reinstalling the system or modifying any settings, and everything returned to normal. Now I can play Battlefield 2042 without issues. I think the root of the problem might lie in the driver optimization for the RX 9070 series graphics card, and it may take a long time for AMD to release a fix. In the end, this issue remains unanswered. That’s it. Thanks to everyone for following this post, and I wish you all a wonderful day. Thank you.

The first thing I check with a new motherboard is to make sure all the screws for the VRM heat sink are tight. The last motherboard I bought came with loose VRM heat sink screws right out of the box.

The second thing I check with a new motherboard is visually inspect all the copper pins in the RAM slots and CPU socket to make sure none of the pins are bent. That's another common manufacturing defect on motherboards.

I think there's something wrong with the motherboard design, so I'll have to go through the trouble of switching back to a B450 motherboard. No more trouble, just let the B450m accompany me to the end.

I give up.

A drive's a drive. Generally that shouldnt have any bearing on things. All signs are pointing to SOMETHING with the motherboard its just the exact bit thats eluding everyone here. 

I’ve checked, and there isn’t a separate VRM temperature option. These usually appear on newer motherboard models, such as the B650 or B850.

Then today I replaced the PSU, but the issue still persists, so it’s not a power supply problem. I’m now trying to move Windows and the game back to the original SSD. A friend said that the new drive might not be suitable for running the system — it’s only good as a game storage drive.

ZksptR​ sometimes VRM is called VR loop, VR MOS, or VR VCC temperature.

Of course, AMD's driver package includes a chipset installation option, and I’ve made sure it’s up to date. I also updated ASUS Armoury Crate, so the chipset drivers are the latest version.

I made sure to check all the sensors, and there is no separate VRM temperature option.It's possible that my motherboard doesn't list the VRM temperature sensor separately, or it might be hidden among the few uncertain temperature readings above.Someone on the AMD forum suggested that I replace my PSU. I've already ordered a new 850W ATX 3.1-compatible power supply online. Maybe it's time for my current 1050W PSU to retire after over a decade of use.

Yeah I'm thinking its something specific to the board itself given OP says the old board was perfectly fine but the new models are having issues. ZksptR​ what about chipset drivers did you update those at all perhaps?

ZksptR​ VRM temperature would be under motherboard data, not CPU data. It's probably further down the HWiNFO list.
