X670E-A mobo stuck on white VGA light, have tried many things

Yesterday, my system went to sleep as normal. Today, when waking my PC from sleep, the screen stayed black and the case fans were a little worked up, like when booting the system. I thought it might be restarting, but it just stayed like that for a long time. So I powered off at the PSU and powered up again. It didn't move past the memory training stage, so I opened the case and saw it was stuck at the white VGA light.

I removed the battery, power cable, held the power button down for a while, and also pressed the clear-CMOS button, then restarted. The issue persisted.

I had upgraded the BIOS to the latest version a day or two before, so I thought that could be causing the problem. I downgraded the BIOS using Flashback and tried again, but the issue persisted.

I next tried removing the GPU and connecting my monitor to the onboard graphics port, using an HDMI cable instead of the DP cable I normally use, then powering up. The issue persisted.

I then removed everything but the CPU, RAM, and storage drives, and powered up. I got the orange DRAM light, as expected.

Then I removed the storage drives and tried with only one RAM stick installed, and I got the white VGA light again. I've also tried each RAM stick, in different RAM slots, and still got the white light. 

I don't know what else to try. Anyone have a suggestion or insight as to what the issue likely is?

Here's a video with everything removed, receipt for the CPU and a single RAM stick.

So I just upgraded to this board and I too am having many issues. Throughout all of my troubleshooting, I noticed there was a setting in the bios to Bifurcate the GPU slot. I think the setting was called GPU + M.2 when it was enabled. When I turned that on, my motherboard was stuck on the VGA light as well. Turning it off brought it out of that stupor though. I can't remember where it was exactly, but I know I had to hit F7 to get into advanced mode, then Onboard Devices Configuration. It might even be the first option under that. Make sure that is turned to Auto, and hopefully it will start working for you. With my luck though, it's already on Auto lol.
