Question EZ Debug LED on VGA, MSI x470 Gaming Pro

So let me give a quick summary of my previous events that led me up to this point: Bought most of my components last year around June (except I
used my old Sapphire Radeon HD 7950 till it died). Built the system with
no problems.

Around January this year, my 2 drives randomly disappeared from the boot
list. Issue was solved by resetting CMOS (I tried replugging in all the
drives before but that didn't work). I replaced my old AMD GPU with my
brother's unused working Gigabyte GTX 1060 3GB Windforce OC Edition. The
GPU would occasionally not be detected but it only happened like once a
month and would resolve eventually. Both issues started happening more
frequently so I decided to update my BIOS to the latest one on July
26th.

Then on July 29th my computer didn't POST with the VGA light being lit
on the 'EZ Debug' LED array. I tried using the other PCIE slots but only
one is accessible with my GPU as it's 2 slots tall. The slot didn't work
either. So I decided to contact the supplier I bought the motherboard
from as I have 3 year warranty. They agreed to test it but I just
received it back this morning with a report that no issues could be
found. I managed to test my GPU on my brothers rig yesterday, and it
worked. I even swapped my PSU just to make sure that wasn't the issue
and of course it still worked. I have reassembled my PC and I get the
same VGA debug LED being lit. I am fairly convinced the motherboard is
the issue but I'm not an expert. I have reset the CMOS. My guess would
have been the PCIE slot is damaged but it doesn't explain why the other
slot didn't work either.

Any advice/ideas would be extremely appreciated!

Sure, I'll give it a go. My friend will be willing to let me test their CPU once they upgrade in early September. I'm still unsure as to how the CPU could cause issues with the GPU during POST but I might as well try...

Thank you for the response! :D
