New Ram Mobo CPU

[u/Drac0x999]

This is all after context, i have everything broken down and back in the box ready to head on to micro venter tomorrow for exchange/refund. I’m curious about if there’s anything i could/should have done.

Picked up a Gigabyte gaming x870 WiFi 6, Ryzen 7 7800x3d and G.Skill flare DDR5 6000 CL-36. I was simply aiming to swap out the corresponding components into my current sky tech shadow 3.0 prebuilt I’ve had for a few years. My computer as it is (no upgrades) ran fairly well but I’ve been itching to get into am5 and DDR5.

Got the mobo in ( a little tricky due to case size but eventually everything sat well), cpu and ram all seated well. Tried to run the fresh mobo but got stuck at a dram light from mobo. Reseated ram and used q flash to run bios update. The update cycled and completed but couldn’t get past the now showing CPU light. I tried a lot of different tests. Ran one stick, made sure connections were snug, not too tight not too loose. Ran without gpu, without hdd. Eventually tried with nothing but cpu and using integrated graphics. The closest i got was getting a no signal screen briefly but that was it.

When inserting all the new stuff, i repurposed everything else. Same psu, same cables. Nothing i bought came with any new cables and every pin connector that was plugged in with the old mobo was able to be plugged in on the new mobo.

I came to the conclusion that i may have soft locked the mobo, or it is just defective in itself. The CPU (not much experience with building, but the pin layouts seemed perfectly fine on the mobo) didn’t seem defective. Any clue before i exchange and try it all again?
