Question I am a beginner PC builder and I need help

[henryr1321010]

When i started building it, i knew there might be some problems but i connected jfp1, all of those, i figured out i had laptop ram on accident and reinserted udimm ram, then I turned it back on, reinserted the cpu and cpu cooler, remounted everything but still, it says "CPU ERROR" I have a MSI Mag B550M Tomahawk (w/o wifi) and an AMD Ryzen 7 5700X, and 64GB Crucial 3200MT DDR4 (2x32GB), I tried to update the bios as well, does anybody have any solutions

Does the box of your mb says that it's ryzen 7 ready? (I believe it is), could you provide a picture or the exact sentence about the error?
