Haven't updated bios yet from what is shipped.

Hello, I recently built a computer in September, and today, while it was left on, had the EZ Light DRAM (yellow) illuminated. The computer was un-repsonive and a re-boot I now have both the EZ lights for CPU/DRAM illuminated.

Some history, it has been a troublesome build. My first motherboard was the ASRock B650M PG RIPTIDE WIFI AM5 Micro-ATX Motherboard. The on first power on had EZ lights for CPU/DRAM illuminated. Did some troubleshooting and decided to RMA. The replacement was same issue! I returned for refund and ordered the MSI motherboard. After waiting ~5 minutes, it finally booted and I was installing debian.

Everything was running great, I just had an ongoing issue where debian was crashing due to [gfxhub] page fault on my GPU. I started with troubleshooting hardware. I installed a XFX Radeon RX 580 GPU and took my Thermaltake W0106RU 700 W (yes from 2007) from my server PC since the 400W could not support it. After a week of no crashing, I installed my RX 6400 GPU again with 700W PSU and crashes happened again. The fix was to update my Mesa drivers through debian backports to 24.2 if I recall. I have been using my PC great with no crashes for 3-4 weeks now.

Today I had a browser open and was updaing nextcloud on the server PC. I took a 3 hour phone call, came back and that is when I saw the DRAM EZ light on and the keyboard backlight was dead.

My old PC was using an AM4 socket and DDR4, meaning I have no "good parts" to swap. What I have done so far

+ Re-seated RAM
+ Use only one RAM at a time
+ Tried all sockets
+ Clear CMOS
+ Removed GPU
+ Remove RAM, power on, power off, re-install RAM

The PC draws RMS 0.331 A off 120VAC. I measured +12.3VDC, +5.1VDC, +3.34VDC

I am at a lost what to do or how I can isolate it. My wifes PC is an intel, but has a ASUS ROG Strix B760-I Gaming WiFi Intel B760(13th and 12th Gen) LGA 1700 mini-ITX motherboard. Could I install my RAM and run MEMTEST86? I assume since the CPU error LED is on I have no means to test on my PC. Any guidance is appreaciated.

Welcome to the forums, newcomer!

Haven't updated bios yet from what is shipped.
And what BIOS version were you on out of the box?

PSU: EVGA 400 N1 100-N1-0400-L1 400W Power Supply (Bought 2019)
I would've replaced the PSU while you were upgrading the platform, if I were you;
Tier F

Just my observation, you seem to have bad PSU's at your disposal for concurrent hardware. To add, did you reinstall your OS when you replaced the motherboard?

Hi, you are right on the money :) I took my old Thermaltake PSU and the PC booted right up with no issues. Thanks for the list, that is very helpful and I will use that for the replacement. Thanks again!
