Hi everyone,

I'm about at my wit's end here. I'm trying to do a build for my wife as a present for her. It's a mini-itx build. I have done builds before and never had issues. This build is probably going to be my last with how frustrating it's been.
The (original) specs are as follows:
  • MSI MPG B650I Edge Wifi (AM5, mini-ITX)
  • G.Skill Trident Z5 RGB Series (2x32GB)
  • Samsung 990 PRO SSD 1TB
  • Noctua NH-L9a-AM5
  • AMD Ryzan 7, 7700x 8-core 16-thread unlocked desktop processor
  • EVGA RTX 3080 XC3 Ultra Gaming
  • Velka 7 Case
  • Corsair SF750 (750 watt)
Initially I hooked everything up including the GPU, and turned it on. Display not showing, and bios not loading. I observed the CPU and DRAM debug lights were on. From there I took everything out and reset it to make sure I wasn't missing any connections.
The next thing I did was order a new MOBO (same model) to rule out the other being dead. Same behavior. I happen to have a ryzen 9 that I know works, and I popped that in to test it out and still getting the CPU light. I changed out the RAM, too. I'm using only the slot farthest from the CPU, and one stick. I've tried all sticks of RAM that I have. Nothing.
I emailed MSI finally and they suggested flash updating the BIOS, which I did. Nothing. Still can't get the display to work.

Extremely frustrated because at one point I walked away and came back and the BIOS WAS showing on my monitor, and it showed the CPU / RAM accurately, but not the m.2 ssd I have. I changed out the SSD and I've been unable to get it to boot again since. I feel like I've tried everything and I'm about to give up on the build that I've sunk quite a bit of money into.

Right now I'm not even connecting the GPU and just trying to get the bios to work. Would appreciate any insight as I feel like I've tried everything from resetting all things, trying a new motherboard, trying a different (working) CPU on the motherboard, and RAM. The MOBO is AM5, and the cpu is as well.
