So my problem is that pc worked fine until yesterday morning. I started pc but it got stuck just after press for bios disapears. Waited but nothing happened so i press start button for 10 sec to shut down. Start again and now windows tried to repair itself. Waited and waited but nothing happened so again i shut it down. Start again and same. So i tried to repair windows from usb stick but after booting from that stick pc is stuck again on that rog logo screen. Then i swipe my ssd where my windows was and tried to install it again. Stuck again in rog screen.

And after that formula led screen is saying detect memory and q 09- PCH initialization after microcode loading. I dont have a clue what that even means. Sometimcodees q code 23. So i thought maybe ram issue. Switch slots, test one by one, test another kit but nothing works. Usually 09 and sometimes 23. Tried with one ssd, with another ssd nothing. Tried wirh out gpu. Tried with only hdd.

Any help from here? Next im about to empty my loop ja taking cpu out and build it again. After that im sending this mobo back to seller.
