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

Recommended Posts

Posted · Original PosterOP

I built my PC about a week 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. The red light is kind of annoying, so I'd love to turn the sucker off somehow.

MSI support got back to me on this question.


They suggest I try updating to the latest Beta bios version on their website.


To be honest, I originally avoided that on purpose when I first built the PC--because it's Beta--and everything's working fine save for a tiny little red light inside my case.


What are other's feelings about Beta versions of bios? Again, my system is running so well now, I hate to take a chance. If things go to hell, can I simply roll back to the previous bios version easily enough?


I mean, is it really a big risk or am I just making something out of nothing (I'm new to all this, btw)?
