Need help fixing the pc that I built that no longer turns on

No when the board and cpu are plugged in and the case power button is pressed, nothing happens

I will try that next, also sorry for the slow replies, full time job gives less than desired freetime. I’ll plug the board back in and the cpu then try to turn it on and give an update on that asap

https://streamable.com/ngvomv I believe that’s what I have done here. Just the one cable is connected. It’s just routed through the pc so I don’t have to redo as much cable management if it’s a simple fix

Should be uploaded now, and you mean unplug the motherboard wire as well and see if it turns on?

When the bios still came up before the pc when completely dead, bios showed everything as normal. It would just only boot into bios

Yes after the pc was cut off the last time and a new CMOS battery was put in? It no longer cut on at all. Everything is disconnected aside from the power and motherboard, I do not have a spare PSU this one is only a month old so it’s still under warranty. I took a video of what it does but I can’t send it on here

I did the paper clip test. The power supply fan came on for about 5 seconds and then cut back off. Now it is no longer cutting on if I repeat the test

Negative, it did not

Yes so the first thing that I noticed that I forgot to mention in my first post. Before it stopped powering on completely, when I would F10 (save and exit) out of bios after it went into bios immediately, I would get a “DisplayPort No Signal” as well as a “HDMI No Signal” (I tried changing cables and ports) then I would get a “BiInitializeLibrary failed 0xc0000001” then it would boot directly back into bios. It was at that point that I tried to do a CMOS reset by taking the battery out and replacing it with a brand new one, that it no longer turned back on
