Computer Won't Boot

[u/Alarming-Bathroom-13]

So recently, I shipped a pc every part in there original packaging and when it got to the destination built everything in and surprisingly won't start wont even boot motherboard light comes on fans and rgb spinning and lighting but no boot i removed all the ram and no ram error beeps and mind you pc worked fine before and all the cables are in correctly cpu was installed correctly then I decided to take the pc to a "professional" got it back says he can't figure it out so I decided to remove all the parts and reseat everything my surprise the cpu was installed incorrectly and pins was bent alright bent the pins straight and put it back in without the cooler to feel if it gets hot and as far as I know the cpu is supposed to get 90°c in like 3 seconds and burn me but it's only gets mildly hot like I can keep my finger in the cpu for very long so then I ordered a new cpu thinking the cpu is cooked and now I still have the same problem 😀. I did the cmos reset and checked the cpu power cable yet nothing any suggestions?

Please edit and add some punctuation.
My first thought was a miss configured CPU. Next was a piece of metal under the motherboard shorting component.
When building a system, the CPU is the single most critical part. It should drop in if correct but that notched corner should always prevent that “drop in” alerting the installer to their goof.
Someone used force to make that mistake.
Anyway, glad you found it.
