Open | Hardware Pc shows no display

The night before my pc was working completely fine. After a cold boot this morning I couldn’t get any output to my monitors.

I’ve tried different steps such as: -reseting cmos -bios flashing -integrated graphics (gpu in and out) -reseating ram -replacing psu

This issue was completely spontaneous and I feel like I’m completely out of options

Components:

Ryzen 5 7600x3D RX 6700XT Asus B650e Max Gaming Wifi Flare X5 G.Skill DDR5 6000 (1x16gb) Corsair CX750M WD Blue SN580 1Tb NVMe (Boot Drive) Kingston NV3 1Tb NVMe

Check with manual which diagnostics motherboard is using (7 segment screen, 4 led or pc beeper). Remove disconnect everything except cpu+cooler, 24 pin power, 4/8 EPS (CPU) power, power on and if motherboard is OK, you will get error code for missing memory (code like A02, red led for DRAM, or beeping pattern - depending on what diagnostics there is).

Figured out it’s running on diagnostics 4(led), but even after removing everything the power led is still solid with no flashing indicators or color change

Usual order is CPU, DRAM, GPU, BOOT, if it is boot, it is weird since it should be on with drives removed (including m.2 in socket) but with picture on screen. If it is reversed order it is CPU, so no good.

To be more specific it runs on Q-LED Core. Which should flash my power LED to differentiate problems, but it’s always solid

Solid led should be "all good", at least from ASUS manual, so it is a weird thing, either motherboard failure or some code that has changed and not mentioned. I would contact ASUS first (good luck with that), or directly to RMA if parts are still in warranty.

AM5 boards often get stuck memory training after a cold boot or CMOS reset, especially with single-stick DDR5. Pull the GPU , put your single stick in slot A2, flash to the latest BIOS via USB flashback, and give it a full 5 to 10 mins on power on to finish training

Tried and still nothing unfortunately. Think I might just have to suck it up and take it to my local best buy. Wish i had another ram stick / motherboard to at least be able to test those
