If he built this PC recently and all those pieces are new (which is why I asked you those questions), then whether the board is cheaper than the processor doesn't matter. Just take whichever part is causing the trouble back to the store and get another one. And if it's because the board can't see the CPU, that means your motherboard has a problem.
It still matters in the sense that money is reserved until the refund is processed. And they might refuse a damaged CPU, but not a damaged motherboard. Seen it happen. But until the OP says something else, there's no telling if it's any of that or just the memory training getting stuck because he didn't let it complete, which is also common for those who never used DDR5 RAM before and aren't expecting a long initial boot time. If he resets the CMOS and leaves it alone for a while and it still doesn't load, 95% chance it's either that specific motherboard, that model, or the B650 chipset overall and in all cases the solution is replace the motherboard.
I looked at those posts above, and they gave me some great tips. Here are a few things I learned as I went along: Try putting in just the basic pieces first and check if the computer starts up. Don't try to add hard drives or solid state drives yet. Just make sure the CPU power plug is connected to the mainboard. If you leave it off, most motherboards won't start at all. Also, push that big power cable for the main PSU down tight on the motherboard and make sure it sits completely flat against the metal. I sometimes unplug and replug these cables many times just to get rid of old rust or dirt on the pins. That is a good trick when dealing with the thick wires used by big graphics cards. If your motherboards have built-in video, see if that happens without any RAM sticks. Sometimes you only get sounds like beeps instead. Make sure you plug an audio cable into the front panel power button and LED hole while you test it. This has saved me many times. In a similar way, some motherboards can start up even with no memory. If you hear those beeps or video sounds, try one stick of RAM at a time to see if just that one is bad. It could also mean a whole slot is dirty or broken. Some of the advice above mentions bent pins. Another very common way to break things is static electricity damage. I read an article that said almost 40% of computer crashes are caused by electrostatic discharge, even years later when you buy new parts. I do a lot of engineering consulting and have seen so many ESD disasters, so this is no joke at all. Always wear an anti-static wrist strap on your PC case while working with parts. These ideas might help out.
