Question Can’t boot PC (NZXT N7 B650E)

[maru2107]

I’ve been having some issues getting my PC to boot since I upgraded parts.

I have:
- AMD Ryden 9 7950X3D
- GeForce RTX 3070
- NZXT N7 B650E
- RM750X
- DDR5 2x16GB

The first time I put it all together, I got two red post LEDs, for CPU and DRAM, however the cpu and ram are both brand new. I tried a few things, updated bios, cleared cmos, and nothing worked, so I got the mobo replaced with a new one. This time, I can get into the BIOS (couldn’t last time) but I can’t get past it. When I turn on the PC, the same two post lights turn on, then they turn off, and the “boot” and “vga” LEDs come on, then they all turn off and I get into the BIOS.

When I go to boot options, I can’t see any of my drives. I have
1x M.2 SSD (windows installed already)
1x SSD
2x HDD
When I go to advanced->storage configuration, I can see all four of these, so the motherboard knows that they’re there, but none of them show up on boot options. I’ve got no clue why this is happening, and I’d appreciate any help.

How old is the PSU in your build?

1x M.2 SSD (windows installed already)
Did you install the OS while on the older board or is it an install from a much older platform? If so, you will need to reinstall the OS after fabricating the bootable USB installer using Windows Media Creation Tools.

I honestly couldn’t tell you how old the PSU is, but it’s less than 5 years. The windows was from my old motherboard. I still don’t understand why none of my drives would show up as a boot option even with that being the case though? I also don’t particularly want to wipe my SSD to have to reinstall windows on it.
