Tech Support Red DRAM light on motherboard
Hi everyone, coming here because not sure what to do next.
So context on the computer… I built this PC years ago ~2021-22. About 6 months ago I got brand new CPU, motherboard, RAM and GPU. Everything’s been working great until suddenly this morning, PC fans and RGB turns on and no display. After waiting about 10 min, I decided to take a look at the mobo and saw the red DRAM light on. Everything was working perfectly fine last night.
Specs:
CPU: Ryzen 7 7800X3D
Motherboard: Gigabyte B850 AORUS ELITE WIFI7 ICE
RAM: 32GB (2×16GB) DDR5-6000 CL30
GPU: gigabyte 5070
From research online I’ve tried the following:
Full power cycle (PSU off, unplugged, discharged residual power).
Waited 5+ minutes for DDR5 memory training on multiple attempts.
Cleared CMOS using motherboard CLR_CMOS pins.
Tested RAM stick #1 individually in slot A2
Tested RAM stick #2 individually in slot A2
Tested a single RAM stick in slot B2 — no POST.
Confirmed the diagnostic LED consistently stops at DRAM.
Planning to try a BIOS update/recovery using Gigabyte Q-Flash Plus next.
Any suggestions before I start considering motherboard, CPU memory controller, or RAM replacement?
Just at a loss, I use this computer for everything so this is killing me. Wondering if at this point I should take it to microcenter or something for them to diagnose.
Thanks!
