PC wont boot reliably (Stuck at RAM and CPU led)

[Joe4Lama]

I have built a new pc last October.

Here are the specs:

ASRock x670e pro rs

Ryzen 9 7900X

Corsair VENGEANCE DDR5 RAM 64GB (2x32GB) 6000MHz CL40

Corsair RM1000e

GTX 1080ti (my old card,will upgrade eventually)

 

I am encountering the following issue about every time I start my PC and every time I reboot.

When I press the power button everything inside the case lights up and fans start spinning, but the CPU and RAM LEDs light up and stay on. There is no power to the peripherals and no output to the display.

 

This state does not change even after waiting for 30 or more minutes.

 

The only thing that I can do to get it to boot is power cycling it (switch off PSU and hold power button for about 30 to 40 seconds) After doing that and switching the PSU back on, the same problem occurs. But after then shutting it down by holding the power button and then powering it on again it all turns on normally and everything works (all of the RAM is detected, CPU works well under heavy loads, no crashes etc.) 

This fix works most times, but sometimes nothing helps for like 30 minutes trying or more and suddenly it starts.

 

I have tried about everything:

- clearing CMOS

- updating BIOS

- replugging all cables

- reseating CPU (multiple times)

- reseating RAM (multiple times)

- enabling/disabling XMP

 

Do you have any ideas what could cause this?

 

RMA of the motherboard or the PSU are my last resort because I need my PC every day for work and university.

Are you sure it's not memory training?  Can take up to minutes especially with 64GB RAM.

I don't think so, I often leave it like that for a couple of minutes but nothing happens. I also tried with fast boot enabled or disabled but it does not make a difference.

DOCP issues maybe?

It also happens when XMP is disabled
