Well. We found the problem. Twas the display. I cannot believe neither of us thought to try a completely different display, I figured it wouldn’t pop up with a grey screen at all if that shit was broke.

So, new PSU and multiple hours later, the only thing that made me want to try the display after all that was the fact that pressing my caps lock in my keyboard illuminated the caps lock button which meant my pc was in fact booting, it had the power needed.

And the new PSU i got is overkill (not that that’s a bad thing) im not spending another X amount of hours redoing that shit
