PC stopped working with DRAM led solid

Go to solution Solved by rip3.141,

Problem is solved.

RMAd the CPU and Mainboard. Got a new CPU and now everything seems to be working fine. Manufacturer couldn't find any fault with the mainboard.

Might have been related to current ryzen problems, but I did not see any deformation on the old CPU.

My PC was running fine till yesterday (Been in use for a few months). When I tried to boot today it powers on but is stuck on DRAM debug led. Screens do not get an image and usb peripherals do not get power. The fans and coolant pump are running, but change speed between full and minimum speed periodically.

Build is entirely liquid cooled and all temps have been below max temps.

 


What I tried:

  • Reseat ram
  • Use only one ram stick (tried both sticks)
  • Reset cmos
  • Flashed newest bios (0925) using bios flashback
  • Disconnected all peripherals
  • Tried dedicated and igpu

My specs are:

  • Windows 10 Pro 64bit
  • ROG STRIX X670E-A GAMING WIFI (BIOS version 0925, latest)
  • Ryzen 7950x
  • 2x32GB Corsair Vengeance RAM
  • Gigabyte 4090 Gaming OC
  • Samsung 980 PRO M.2 NVMe SSD (1TB) boot drive
  • BeQuiet DARK POWER PRO 12 (1200W 80+ titanium)

Any tips on how to debug this situation further would be greatly appreciated, as I do not know where the fault could be.

Ok, I did some more debugging:

  • Tried ram in a friends pc - Works fine
  • Attached a beeper to the mainboard - No beep codes at all

My thinking is that either the cpu or mainboard has a fault.

The problem is, that I have no other am5 platform to test the CPU.

 

Should I just rma it? Any other Ideas what could be causing this?
