Question System turns on, Red LED, turns off, on again, stuck at Green LED

[chaydon117]

I just got together a simple set of upgrades, these being

AMD Ryzen 7 5800x
Asus Proart b550-Creator (BIOS version 2407)
Crucial DDR4 pro 3200MT/S 32gb (2x16gb)
Teamgroup MP33 512gb M.2 SSD
Cooler Master GX III750w

but when I reassembled my machine, I turn the system on, slight time on yellow LED (Memory test) before going to red for less than a second before shutting itself off. Then, it turns itself back on, goes through the checks and gets stuck at green LED (storage) with no POST, no BIOS. Nothing.

I have tried practically everything in the book. CPU-reseat, Memory swapping/testing with one stick. SSD removal, PSU changeover. Nothing has worked.

I'm honestly getting close to ripping hair out, so any help would be immensly helpful.

ps. I don't have have spare am4 chips or ddr4 module to test so there might be that blindspot. I would rather get a full confermation before I am forced to buy yet more components for what was supposed to be a simple upgrade.

Have you double checked that the m.2 is seated fully. If the board has two slots try the other one.

If that does nothing, do you have a spare hard drive to connect to see if it posts. Remove the m.2 before trying !
