Question PC won't boot, fans start for a few milliseconds and RGB on RAM.

[xeryl]

Just got done with my new custom build, and when I press the power switch, its like a small flicker of life before the whole system dies again. If I didn't notice the small movement I would've thought that the power switch was the problem, but then I saw that everything would turn on for a split second until dying. The fans on the case spin, the CPU fan spins and my GPU's fans spin for a very tiny fraction of a second until they die again. The oddest part of all this, the RGB on the RAM stays on for some reason. I originally thought that it was training the RAM, but after 30 minutes or so it was still dead with just the RGB on the RAM working. I get no debug LEDs on the mobo, either. Let me know what you guys think, I really need the help.

Here's my specs if it helps:
mobo: Gigabyte AORUS B650 Elite AX
cpu: Ryzen 7 7800X3D
ram: Trident Z5 RGB 32GB CL32 Intel XMP(2x16) in the second and fourth slots
gpu: Gigabyte RTX 4080 Super OC
and then I have a samsung 2TB m.2 SSD and a couple sata harddrives.
I think the case might be the biggest culprit to this problem, as it didnt seem to have many plugs to plug in, but I assumed maybe that was because it had a fan hub. My case is the Cooler Master TD500 mesh V2

Are ALL the cables properly plugged in, as well as all the front panel connections?
Recheck all the cabling and also remove them and re-plug them to begin with.

Next, reseat the components, starting with the RAM, GPU, then finally if no avail, the CPU (maybe do this at the very end as you'll have to re-apply thermal paste after removing CPU).

really hope I don't have to, dont wanna damage the LGA socket
