Hello, so yesterday I built my first build and everything when fine. it worked for about an hour then out of nowhere the computer shuts off and would not turn back on. I tried turning off the PSU and unplugging it for a little while then plugging it back in but that didn't work. when I press the power button nothing happens, no fans try to spin even the PSU one and also I have LED's on the motherboard and graphics card the turn on when they get power and none of them turn on or even flash when I hit the button. I'm thinking it the PSU was a faulty one but I wanted some other opinions. thank you for any help you can provide.
