Question New mobo and CPU, booted to bios yesterday but white VGA light today

[vasec]

Bought a new case, mobo and CPU and everything seemed fine yesterday when I built it. Only issue was that it booted to bios and couldn't detect any bootable device. I figured I needed to do a fresh install of windows but that I could do that the next day (today).

This morning, I can't even get to the bios and the mobo's white VGA light is on.

Any ideas what could of happened and anything I can try to fix this?

Mobo: Asus TUF gaming x570-PLUS wifi
CPU: Ryzen 5800x
GPU: MSI RTX 3070
PSU is a modular 850w bronze

Edit: My GPU worked fine in my previous setup, the lights/fans turned on in the new build

Edit 2: PSU is Thermaltake TR2 RX 850 Bronze (not gold)

Did you reinstall the OS after the motherboard swap?

What is the make and model of the unit? How old is the PSU in your build?

I did not reinstall the OS, I can't get to the bios and I can't get it to boot on a flash drive with windows on it.

The PSU is a Thermaltake TR2 RX 850w and I can't remember exactly when I bought it. Think I got it when I purchased a GTX 970 7+ years ago.

After hours of troubleshooting, the motherboard is defective and doesn't recognize any GPUs in any PCIe slots
