PC not posting

Zonal · December 30, 2022

I just finished installing an asus prime b650m-a ax along with a ryzen 5 7600x and g.skill flare 5600mhz 1x16gb ram. This is paired with my previous evga 3060xc which had worked just fine before.

Fans and aio all work perfectly and everything seems fine except for the pc won’t post and the case (Lian li air mini) power button is blinking.

I tried taking out the gpu, taking out the ssd, reseating the ram, reseating the cpu cable, reseating the gpu cable. Also I’m using displayport if that matters at all. Any advice would be greatly appreciated.

Ryzen 7000 series now has iGPUs so you can plug a cable into your mobo and test if it posts as well without the GPU.

Adding to this, I would also check that your RAM is validated for the board (https://www.asus.com/motherboards-components/motherboards/prime/prime-b650m-a-wifi/helpdesk_qvl_memory/?model2Name=PRIME-B650M-A-WIFI). you can also use the BIOS flashback to make sure you're on the latest BIOS. Test different DIMM slots on the board, try re-seating your GPU, etc. Might be worth double-checking the wiring to make sure it's all connected properly, especially that front panel I/O.

May I also ask why you're only running 1 stick of RAM instead of two? I have seen in the past some boards refuse to boot in single-channel, and will only work when properly operating in dual-channel mode.

It was a deal where you can get the ram with an am5 cpu. I’ll try some of that. Thanks!

I am having this same problem but with the Ryzen 9 7900. Did you find a fix for this? I have tried flashing bios, removing cmos battery, returning the it and getting a new one.

not a fix, but I've sent it in to asus as an rma and they're saying it's a broken pin in the socket. They want to charge $135 even though its under warranty but I'm definitely not paying that much.
