Question DRAM Qled on, replaced almost everything, boots sometimes.

[Rhekk]

TLDR: PC wouldn't post, replaced everything but GPU and CPU, now boots occasionally. DRAM Qled is on after every restart, sometimes leads to boot.

(Specs after replacing PSU, Mobo, and Ram)
OS: Windows 11

Mobo: ASUS TUF B650-PLUS WIFI
Processor: AMD Ryzen 7 7700x 8-Core Processor
GPU: MSI GeForce RTX 4070Ti Ventux 3x OC
PSU: Cooler Master MWE Gold 850 V3 ATX 3.1 Modular PSU
RAM: CORSAIR VENGEANCE DDR5 RAM 32GB (2x16GB) 6000MHz CL40 Intel XMP
CPU Cooler: RGB AIO 240mm (included in prebuild, no idea what brand)
SSD: 1TB NVMe M.2
Secondary SSD: WD_Black 2TB SN770 NVMe M.2

Last weekend we had a power outage. My computer tower would boot up afterwards but would not send any signal to the peripherals, the CPU and DRAM Qled lights were on which according to the manual suggested the Mobo was not recognizing the CPU or DRAM. I could not access the bios even after CMOS resets and even bios flashback.

I tried most troubleshooting methods under the sun. I replaced the motherboard. Upon replacing the Mobo the tower would boot, DRAM Qled persisted. It was still not turning on the peripherals as well as the Chassis fans were not spinning, however the RGBs were lighting up. Reseating the ram into different slots would occasionally let me access the bios but after saving and restarting it wouldn't boot.

I replaced the PSU at this point. With the PSU replaced the DRAM light continued to persist so I tested each RAM stick individually to find that one would boot the PC while the other would not.

I opted for new RAM, with the new RAM the Qled light still comes on upon turning on, and the Chassis fans start to spin before stopping. It can take several hard resets before things start working properly . The DRAM Qled persists on boot up before it cycles through the CPU, VGA, and BOOT lights before the pc properly boots.

DOCP/XMP is on, I haven't updated the bios yet, windows 11 is up to date.
CPU is the last integral component I haven't replaced yet.

Welcome to the forums, newcomer!

By replace, you mean you replaced them with like-for-like parts?

RAM: CORSAIR VENGEANCE DDR5 RAM 32GB (2x16GB) 6000MHz CL40 Intel XMP
Ideally you're advised to look at ram kits that have AMD's E.X.P.O advertised on it. Could you pass on a link to the ram kit?

Wait. So the ram listed above is the new kit? If so, what was the old kit?

I haven't updated the bios yet,
If the motherboard has BIOS versions pending update, that's the first order of business. You can flash the BIOS using this method;

After all of this, if even using ram meant for AMD's AM5 platform doesn't help...since you're left with the CPU and GPU from your older build, it's possible that the integrated memory controller on the CPU conked out during the power outage.

Hi, thanks for the response, I've been helping him over discord thus far, so I can answer these questions.

The pieces he replaced were:

• Motherboard: MSI B650-P Wifi
• RAM: Kingston Fury RGB 16GB DDR5 5600 MHz (2x8GB)
• PSU: 700W Gold

He didn't buy an EXPO kit because he didn't know about it (This is the first time he's really worked on a computer) and he bought the kit before I could tell him there was an expo one lol.

He has tried updating the bios of his previous mobo when we couldn't access it, via the flashback port/button, but results were less than stellar and the light would stop blinking and be permanently on, so he's anxious, but I told him updating a working BIOS should be easier, he'll try it now.

Alright, he first attempted the Ez Flash utility, but it restarted after pressing start, and then wouldn't boot.

Then he used the flashback function successfully, and it went through the cycle of DRAM QLED-> after 30 seconds or so, other QLEDs blinking for a sec->Booting, it went into bios, let him set up DOCP again, restarted and went through the cycle, then it cycled again for some reason, and now it's booted and operating.

It seems like it boots somewhat reliably, but under normal operation previously in his PC, he'd never had a QLED light up and his computer would boot immediately without issue, so it still seems like things aren't alright.

He also ran a memtest previously with his new sticks.
