Intermittent Boot Cycle Issue – X670E System Randomly Fails to Post

Hi all,

 

Looking for help with a frustrating issue on my  AM5 build. My system runs perfectly for days, then randomly typically after being powered off all day it enters a boot loop. The system turns on, fans spin for a second or two, then it powers off and repeats endlessly. No consistent Q-Code is shown, it varies or shuts off too quickly to read.

 

Here’s my build:

 

  • CPU: AMD Ryzen 7 7800X3D
  • Motherboard: ASUS ROG Strix X670E-E Gaming WiFi
  • RAM: G.SKILL Trident Z5 RGB 48GB (2x24GB) DDR5-8000
  • GPU: ASUS TUF Gaming RTX 4070 Ti OC
  • Cooler: Lian Li HydroShift 1 AIO
  • Fans: Lian Li Uni Fan SL Infinity (7 total, daisy-chained with controller)
  • Case: Lian Li O11D EVO RGB
  • Storage: Samsung 990 PRO 2TB NVMe Gen4
  • OS: Windows 11 Pro
  • PSU: Corsair RM1000x

 

 

What I’ve done/tried:

 

  • PC has run fine for 2+ weeks between incidents
  • Happens randomly after the PC is left off for a while
  • Disconnected all accessories, fans, and GPU—still boot loops
  • Motherboard tested out of case on cardboard
  • Tried different RAM kits (same issue)
  • BIOS is updated; no XMP or memory OC enabled
  • System is connected to a PSA 1500VA

 

 

This issue only occurs on this ASUS board no issues when using a Gigabyte AM5 board.

 

Has anyone run into something similar or have insight into this behavior? Could this be a board-specific hardware issue?

Hello @Epicgamer347 

Thank you for reaching out to us.
Could you please clarify if this issue occurred after the PC was first built or after using it for some time and occurred following any recent changes, such as a BIOS update or component replacement?
Based on your description, it appears that the issue occurs randomly. May we ask if you have observed any specific scenarios or steps that tend to trigger the problem more consistently?
What is the part number of the RAM modules you currently installed, and are they listed in the ROG STRIX X670E-E GAMING WIFI QVL? 

Please also specify which slots your RAM, GPU, and SSD are installed in, as well as ensure there are no bent pins in the CPU socket, and confirm that the CPU is installed appropriately.
As the issue seems to occur frequently and is reproducible, we kindly ask that you provide a more detailed scenario description along with a full video recording that captures the problem, including the bare board test and results from minimal hardware configuration. 

Thank you.
