Node 202 pc won't post

So I’ve been building a pc for my friends brother using the following parts

and the issue with the computer is that it won’t post into the bios and I haven’t even gotten the os on the computer and I don’t have the computer at my house and need to go down to his house to get it to work but idk why it won’t post into the bios, I’ve built my own pc and never had issues this bad and would appreciate any help.

Some isn’t seated correctly or t DOA. Did you test the components before you built it?

It turned out the issue was we had the wrong cpu in the motherboard, The pc was built months and has been running well sense I’m just typing this now to put on the record that it’s working.
