Need some help troubleshooting mobo

Hello all, I built the PC in my sig back in March 2020 and added the video card in August 2020. It has been working flawlessly up until yesterday. In the middle of my wife using it, it suddenly crashed. We go to turn it back on, everything powers up and the CPU warning LED illuminates on the mobo. The system won't turn off with the power button, I have to switch off the PSU to make it turn off. The manual provides nearly no information on how to troubleshoot the CPU LED, and I do not have a spare CPU to tell if it is actually a CPU problem or a mobo problem. I have contacted Gigabyte support about this, but I am unsure if the mobo is still under warranty or if it is even a problem with the mobo. So far I have tried:

Unplugging everything except the monitor, still won't POST
Cleared the CMOS, no change
Re-seated the RAM, no change

A friend of mine is suggesting flashing the BIOS, however I am a little hesitant to take that step before I hear back from Gigabyte (plus it's been 15+ yrs since the last time I updated a BIOS LOL). Does anyone here have any suggestions for further troubleshooting steps I could take?

Thanks!

When you say "unplugged everything" does that include the internal storage devices? You might be able to at least get into the BIOS with them removed -- if so, the problem could be one of the drives dying.

No, it didn't. However, I just tried that and still no good. At that point the only thing plugged in was the GPU, RAM, CPU, and the various front headers. Thanks for the idea!

Still haven't heard back from Gigabyte support, but it IS still under warranty, as is the CPU. Just not sure how to tell for sure whether it is a problem with one or the other.
