Question PC won't post, motherboard LED cycles through error codes ?


Sep 30, 2020
Hello friends, after shipping my computer overseas it refuses to POST. Fans turn on, there is LED on the motherboard, light etc... Worked normal before shipping. It has been in shipping for approx. 2 months.

Monitor and case wasn't damaged at all, it doesn't seem like it was a rough shipping.

CPU: Ryzen 5 3600x
GPU: GTX 1060
RAM: HyperX Fury RGB DDR4 2666MHz 16GB (2x 8 GB)
Motherboard: Asus Rog Strix b450-f Gaming
PSU: Corsair vs550

I looked at the debugging led indicators and it just cycles through the different colors.
Starting with: Red -> Amber -> White -> Green, and then repeat.

Things I've tried / symptoms
  • Reset CMOS battery
  • Reseating ram
  • Tried booting with 1 ram stick
  • Tried ram in multiple ram slots
  • Tried reseating GPU
  • Booting without ram, just gives me amber indicator
  • Booting without CMOS battery, still cycles led error codes
  • USB devices doesn't light up
Hope I can get some answers as to what I should do, thank you :)
