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.
