Hi all!

I am in middle of building a new PC - I put together all the components and flashed the bios prior to first boot. However, the system does not post. It gets stuck on code C5 (00 -> 46 -> 15 -> C5). So far I've tried:

- Waiting for 15-20 minutes on C5 code.

- Try booting with a single RAM stick, different slots.

- Flashing 2nd bios.

- Checking for bent pins in the CPU socket on motherboard (see pics).

Everything seems okay. But it's still stuck on C5.

What could be the root cause?

I was thinking of getting another RAM stick (slower, lower capacity) to check if that is a problem. Any other suggestions?

Components:

CPU: AMD Ryzen 9950X3D2

MB: MSI X870E MEG ACE MAX

RAM: Patriot Viper Gaming RGB Elite 5 Ultra DDR5-6000, CL 28, AMD EXPO, 2X48 GB

Any help is really appreciated!
