This is what fixed it for me!

Good luck and happy many hours of troubleshooting!

April 2, 2025ASUS Prime B550M-A WiFi II or MSI PRO B550M-VC WiFi ProSeries Motherboard
Both are near equivalent in performance. If the same price, prob go with the MSI since has better reviews. Both have WiFi 6, and B550 features. The MSI has a front USB C port if needing that for the case, and has a M.2 heatsink if going to be using high performance SSD. If using a MicroATX case, the GPU slot sits lower on the Asus so the GPU will be lower to the bottom starting on the 2nd slot down on the back of the case, whereas on the MSI it sits higher in the first slot on the back of the case. The main difference out of the box, is that the Asus will support 5000 series CPUs right away, while the MSI might need a BIOS update. However, the MSI does have a BIOS flash button 'M-flash' to update the BIOS by USB drive, so won't need an older CPU to perform the update. Will just need another computer to prepare a USB drive with the BIOS update. Also, is this a new build? Any thoughts of going AM5 AMD instead of AM4 to have a better upgrade path in the years ahead? AMD just announced today at Computex AM5 support through 2027. More on reddit.com

r/buildapc on Reddit: Is ASUS Prime B550M-A WIFI II a good motherboard?
November 10, 2022 -
So I need to pick a motherboard for my PC, and was looking at the ASUS Prime B550M-A WIFI II, as it is cheaper than the MSI B550M PRO-VDH WIFI. But I couldn't find any reviews for it online (I could for the one without the II, but not for any with it) Does anyone here have experience with this board? Is it pretty much exactly the same as the one without the II?
Also, Will this board work with a 5600? It doesn't come up on the part picker that it might need to be updated, but it doesn't have bios flashback, so was wondering if that's why it didn't come up. I'm pretty sure it does, but I would just like to check if anyone knows for certain.
Thanks

The II is guaranteed to be compatible with any 5000 series CPU, it doesn't need a BIOS update. Its WiFi module is probably lower quality than the original's. The original specified that it came with an Intel WiFi 6 module, which is as good as it gets. The II doesn't specify what module it has. There's no other significant differences.
