I'm sorry if this is in the wrong place but my pc decided to brick itself a few months ago, I originally got told it was the cpu that bricked but I recently replaced it and the motherboard and it's still not booting, it'll run the boot up cycle and go to boot the bios then just stop,
I'm out of ideas as it's a new cpu and mobo and mobo is saying that the RAM and GPU boot up fine, I don't really wanna be spending loads on a new psu or cooler to find out it wasn't one of them so if anyone has any ideas that'd be great

specs;
CPU: Ryzen 9 5900x
Mobo: Asus TUF x570
RAM: Corsair Vengeance 32GB (8GBx4) @3600mHz
GPU: MSI 2070s Trio

it's a Be Quiet! Pure Power 11 700w
as for the BIOS I'm not sure because I can't get into it, I'm assuming its the latest, as of 20/10/2022, as I bought a CPU/MoBo bundle
