I hadn't used my PC in a few weeks, but yesterday was patch day on Final Fantasy XIV so I booted her up and was able to play all day with no issues. When I exited the game to the desktop, however, I noticed there was a sort of green digitization all over the screen and everything was unresponsive. When I restarted nothing happened. The monitor wakes up but doesn't display anything (not even the motherboard splash screen) but the lights on my mouse and keyboard come on. I unplugged the HDMI from the GPU and plugged it directly into the MOBO and the same thing happened, making me think it's not a GPU issue. I swapped the PSU and GPU into my old computer (an i5-2500k build) and the same thing is happening, making me think it's not the motherboard or CPU. Could it be the PSU? Any ideas? Here are my specs:

EVGA GTX 1070 FTW (fairly new as I just had it replaced under warranty)

Ryzen 5 (don't remember the exact model)

Gigabyte GA-AX370 Gaming 5 motherboard

EVGA G2 750w PSU

EDIT: I put my old GPU (an EVGA GTX 680) in the old i5 build and it booted up no issue. I'll replace everything back into my newer Ryzen build with the old 680 card and see what happens.

I think you are on the right track and I'd lean on it being the PSU as well.
The problem follows the PSU. It doesn't follow the GPU (as the problem happens when you are plugged into the MB)....and it doesn't follow the MB.

They dont work in another PC and the video of Igpu was the same. What happens when you put the power supply from old computer to new one? (make sure it's enough wattage)with and without Gpu
does old computer have an Igpu? (try power supply without Gpu in old system too)

The old computer doesn't have a PSU. Unfortunately I only have the one.

I just edited my original post. I put my old GTX 680 in the old computer and it started up fine, making me now think the GTX 1070 is causing issues. I'll replace everything in the new computer and try it out.
