VGA light randomly ( randomly hangs on POST )

What hardware checks? You might be able to manually set the RAM and I suggested setting boot device to the SSD only so that wasnt looking at the USB ports but you couldn't find the setting for that; you cant stop the POST process detecting USB devices completly otherwise the keyboard etc wouldn't work in the BIOS.

hmm i see

i will see if i can find something else but my list of bootable devices only lists my ssd
 
You may as well try it.

You could also use NVCleanstall to remove the HD audio from the GPU driver, then the only source of audio will be from your USB DAC.

i can be wrong but i´m not sure if disabling the driver disables the hardware as well

for motherboard we can 100% disable onboard audio or igpu from cpu let´s say

but i don´t know if removing the driver can disable the audio 100% from the gpu

If you remove the audio from the Nvidia driver, only the audio is diasabled. (i have removed it from my driver)

So if that and motherboard audio disabled there will be no conflicting drivers and the USB DAC may work properly.

It's worth a try and is reversible if it does not work.
