I have a pc that I built years ago that suddenly stopped showing display and mouse keyboard no longer light up. It has been working fine for 3 years. The hdmi got disconnected, I plugged it back in, it had a static screen and then I got no display on the screen. There were NO problems before this and nothing to indicate there was any type of hardware failing. It was working just fine before the hdmi came out. I have tried a new monitor, new hdmi, one stick of ram, no ram, moving ram, reseating cpu (inspected pins before doing so, they looked good) moved the gpu to the other slot, resetting cmos, replacing cmos battery. Still have nothing. The fans turn on, the motherboard is lighting up in the back. The LED light is on for the cpu. The cpu fan is plugged in, the cpu is plugged in correctly. The only thing I haven't done is get my psu tested and of course buy new parts to start narrowing down the culprit. It's an older pc so I haven't been in a rush to fix it but my kids use it and I want to get their grubby paws off my pc and laptop. Any help is appreciated. I will put specs below. Thanks guys!!!

I can't remember the psu brand. Pretty sure it's EVGA and it is 750 watt. It is compatible though, made sure through pc part picker.
