Buildapc

Hi all,

First PC build in about a decade. I've seen this issue multiple times online but no real solutions posted and the few I have seen haven't worked.

AMD RYZEN 5 7600X 6 CORES 12 THREADS UP TO 5.3GHZ THERMALRIGHT ASSASSIN X120 REFINED SE ARGB CPU AIR COOLER SAPPHIRE PULSE RADEON RX 7800 XT 16GB GDDR6 GRAPHICS CARD CORSAIR RM750E 750 WATTS FULL MODULAR LOW-NOISE ATX POWER SUPPLY MSI PRO B650M-P AM5 mATX Motherboard [PRO B650M-P] G.Skill Ripjaws S5 32GB (2X16)DDR5-6000 CL30 BK Kingston 2TB NV2 PCIe Gen4 SSD [SNV2S/2000G]

I've taken a lot of care, read the manuals and watched videos/tutorials on steps as I went. It was pretty much as I remembered the last time.

I complete the build, turn it on and get the red and yellow light on the EZ Debug.

I have reread the manuals, read Reddit and forum threads, watched YouTube videos of individual component installs to see if I've done something wrong - I don't get it.

I pulled the GPU and one stick of RAM.
CMOS Reset. Tried combination of Ram in different ports. Reflashed BIOS, saw it was a beta, downloaded last stable version and reflashed.
Pulled and reseated CPU plug. Changed out to second CPU plug. Used both CPU plugs on PSU. Reseated CPU and heatsink.
Tried every ram slot with both sticks.

I've run through every solution I can think of and read about, nothing works. Any ideas?

Imgur album, hopefully I've just missed something and I'm an idiot.

Thanks in advance.

EDIT - I've tried every suggestion in the thread, I thank you guys for your assistance. I have no idea what the deal is. I have no other PSU/MOBO/CPU. The parts are split between 2 stores, so this should be painful.
