RTX 3050 6GB GDDR6 Screen Strobing

I went to consumer chat first but apparently they only deal with Windows… So they sent me here.

Bought a new PC and Win boots just fine, went to put a Tails Live USB in and when it starts to load (makes it through boot loader) i get the error “Hub Has No Ports” (or something to that extent) the screen goes greyish white and 15 seconds later it’s flashing lie a strobe at 100 mph…

Any help would be greatly appreciated .
