AMD Ryzen 7 3800x not posting, QCode 10 PEI Core is started

[Emptyboi]

Hello,

 

I am coming to you for help after not finding any solutions to my problem.

 

Brand new:

Mb: Asus ROG Crosshair Hero VIII Wifi x570

Cpu: AMD Ryzen 7 3800x

Ram: Corsair Vengeance 3200MHz (2x8)

Psu: Corsair RM650x

 

Used and working fine (had these in my previous build), and still using in new build:

Gpu: EVGA 1060SC

Hard drives: boot drive KFA2 120 Gb SSD, 960 Gb Kingston SSD, 1To HDD, 2To HDD

 

So, after I built everything with the new stuff, all pluged-in and everything, it didn't boot and stopped at QCode 10: PEI Core is started.

 

After looking at some forum posts on the internet I tried changing the ram (bought the new 3200 for that, I had 2133 before from Corsair as well).

Tried my previous psu (EVGA 500W 80+).

Tried to boot without any drives, and just with the OS drive after that.

Tried to boot with only 1 ram stick in the A2 slot (farthest on the right), and with both A2 and B2.

 

Nothing worked and I'm still stuck with my QCode 10...

 

If you know anything about this error I need help please.

I'd be glad to provide you with any more details if you ask.

 

Thank you

 

EDIT: my old ram sticks now don't work on my old build anymore, qcode 53, even after multiple swaps and tries in every slot...

Still need help please!
