So my friend just built a new pc. We put it all together and prest start. The computer started at first but shortly shutdown and refused to start aging, no fan spinning, nothing. So going through the steps and we found that one of the CPU pins (AMD Ryzen 5) was bent. We bent it back and plug it back in to try agin, nothing. Later on we found that the PC starts (fan spining and lights) when we un plug the CPU Power. So now the question is, do we have a dead cpu or motherboard. Or can it be the PSU?
