MSI B550 Tomahawk: "VGA" Debug LED Lit, But System Running Flawlessly

[SDK^]

I built my PC a couple of days ago, and it's been smooth-sailing the whole time. The computer booted up and has been running (and overclocking) like a dream. No issues whatsoever.

However, my MSI B550 Tomahawk's "VGA" debug LED has been continuously lit from day-one.

According to the manual, this LED means "GPU/PCIE/M.2 device is not detected or fail."
Could this be because I've only populated one of the M.2 slots (the PCIe 4.0 one) with my SSD, and the second M.2 slot is empty?

It's the only thing I can think of. Like I said, this PC has been running flawlessly. No errors, BSOD's, etc. I couldn't be happier.

Any ideas as to why this LED is on?

I’m running with an NVIDIA 3070 and one NVMe drive.

Since this could be not only gpu issue I would simply disconnect anything like m2 or other pcie expansion card u might be using and check if it post without this VGA led on. If it fixes the problem than connect stuff again one by one and check if post properly each time u connect something and you will be sure what's causing the issue. Are you sure you don't have a hdmi cable plugged into mobo hdmi port? Your CPU probably does not have a igpu build in so that could eventually be causing this led to be lit even tho everything works.
